FROM THE DESK OF THE PRESIDENT

Hello, please allow me to introduce myself. My name is Eric Girven; I hold the following RETA Certifications: CARO & CIRO. I am also one of only 13 (at this time) RETA Authorized Instructors (RAI). I have been involved with industrial refrigeration for 25 years and close to 15 years as a RETA member. Most of my career to date was spent as an operator, technician and manager at a large beef processing facility in Northeastern Pennsylvania. Now I live in the contracting world providing project management and compliance needs to customers in the Northeast. I am humbled to be part of the leadership team—President—for the Northeastern Pennsylvania Chapter. We have a smaller Chapter than most (78 members), but host great meetings and a very successful golf outing each spring due to the hard work of many chapter members. Similar to the RETA family, my family is extremely important to me. My wife Stacey and our three kids, Emily, Jacob and Lucas, are very supportive of the commitment it takes to be involved in this industry. Their love and support means more to me than anything. I am excited for the upcoming year for our organization. We have many things going on behind the scenes that will make a huge difference for our membership and the industry. We have great relationships built with many partners within the industry that will help us meet our Mission Statement and keep our membership on the forefront

of Education and Certification. I look forward to the upcoming responsibilities as the National

Board of Directors President. I will be relying heavily on the Directors for their input and knowledge. This coming year is going to be very productive.

RETA President Eric Girven

If you were fortunate enough to attend the recent Hershey Conference you witnessed a great event. Two days of hands on training as well as many other opportunities for PDH credits and networking. The numbers haven’t all been tallied but what have been shared has been very positive. The RETA staff and volunteers did an awesome job of ensuring the conference ran smoothly. As with any event as large as this, there will be lessons learned and improvements implemented for next year. A big thank you goes out to all of the Committee Chairs, their sub-teams and all of the volunteers that spend countless hours providing expertise to ensure the RETA Organization continues to meet our Mission Statement. Please contact the National organization if you have interest in volunteering. You can manage your time commitment to fit your schedule. Best regards, ~ Eric Girven, CARO, CIRO, RAI

FROM THE EXECUTIVE DIRECTOR

The theme for this year’s Past Presidents Dinner was “Family”, and that is how I felt when I looked around a room full of people I have come to love and respect, with an organization that means so much to me, RETA is family, my family. The dinner took place at The Mill in Hershey, Pennsylvania during the 2017 RETA National Conference. The Curry family built The Mill in 1880 as a warehouse to store grain and feed. As time passed, due to high demand, coal was added, becoming a staple in the community. In time, The Mill became a gathering place. RETA isn’t much different than The Mill. Our founders saw a need and built an organization to meet that need and feed its members. RETA wouldn’t be where it is today if it wasn’t for our Past Presidents. The RETA Past Presidents not only honored the past, but they embraced the future. This small group came together for a short time to reminisce and enjoy our Family.

Guests arrived at The Mill and were led to the top floor where they were greeted by friendly servers, long farm tables, and welcoming table décor which set the mood for the evening. Everyone mingled, hugged and ate some appetizers just like any other gathering. Dinner began and everyone sat and just like with Family at Thanksgiving, people passed plates, served each other, laughed, and remembered. Looking around the room, I was touched by the many Past Presidents who were sitting among us. It seemed to me that everyone was feeling how special this gathering was. After several courses, I passed the mic and asked the Past Presidents in attendance, “What RETA means to them?” Speaking from underneath what looked just like the cog in the RETA logo, was Alex Gooseff (Past President 1975). Person after person speaking from the heart about what RETA means to them. There wasn’t a dry eye in the house. I still find myself thinking back to that night at The Mill, where a special group of people laughed, cried, and came together to honor the Presidents from the past who were dedicated and determined and who made RETA a family. ~ Jim Barron

WHY VITAL UTILITIES ARE ... WELL ... VITAL

I always wonder why refrigeration is given the importance it is often shown. Some facilities treat refrigeration as an inconvenience. Others treat it as a curse. I prefer to think of refrigeration as the catalyst for profit. “Profit? Utilities costs money, we sell ice cream not ammonia,” you say. While that may be true, let’s think about that for a moment. To sell ice cream, we have several components. The costs can be broken down into the following: • Ingredients • Direct labor (the labor needed to make ice cream) • Physical structures (the structure and equipment needed to make ice cream) These are the costs you would have if you were making ice cream in your garage. Well these and some utility costs such as electricity. But if you were to break down your costs, you would find that these are a small portion of the costs of a modern industrial ice cream facility. The additional costs? • Indirect labor (the labor needed to support the people who make ice cream, the people who sell the ice cream, and the people who move things around) • More equipment (to clean the processing equipment, fork trucks, offices, bathrooms, etc…)

• More structures to house the ancillary equipment.

But at this point, you still would have little more than a syrupy sweet goo. Refrigeration makes ice cream ...well...ice cream. Otherwise

you have ice creammix. Ever want to sit down with a big glass of ice creammix on a hot day? To be totally honest, without refrigeration the milk would spoil before arriving at the facility. It all starts with refrigeration. Suppose we have a nice new shiny ice cream facility, but no milk. As long as we have refrigeration we can make slushes or popsicles. What about water and steam? Without them, there is no CIP, no sanitizer stations, no evaporative cooling of the condensers. What about electricity? Imagine mixing all of the ice cream by hand, in the dark, and without air conditioning. Not a lot of fun. How long do you think your workers would work under these conditions? Don’t forget about OSHA, they may have something to say about the working conditions. Some industries predict that 20% of the cost of their products are direct utility costs.

So how important do you believe utilities to be now? A 10% increase in utility costs results in a 2% increase in product costs. How long will your company maintain their market share if your competitors have a 2% advantage? Keeping utilities operating at peak efficiency is not merely important, it is vital! I remember a story about an engineer at a frozen dessert facility. He submitted a much needed utilities project budget. His boss told him they wouldn’t spend the money. The engineer looked at his boss and said, “We better change the slogan, because we won’t be freezing anything.” Utilities are the backbone of everything we do. Electricity, water, and refrigeration. So, the next time you’re annoyed by the resources (people, time, money) taken by VITAL utilities. Remember you won’t be in business very long without them.

ENERGY BALANCE & SYSTEM PERFORMANCE

By Andrew Fiala, SCS Tracer

If an ammonia system is subject to the OSHA process safety management (PSM) regulations and is built after May 26, 1992 it is required to have an energy balance. Regardless of whether or not a system was built before or after that date, it is still important and useful to have a documented energy balance. Why? An energy balance can be used to show deficiencies in system capacities; are the compressor capacities greater than the evaporative heat transfer surface capacities and are the condenser capacities greater than the compressor capacities? Compiling the data necessary for creating an energy balance can be obtained from the equipment manufacturers. Once the basic data has been collected it can either be filed and forgotten, or used to produce some really amazing information about an ammonia system. The information obtained from the manufacturer is the equipment’s optimum performance data at specific temperatures/pressures. Most compressor manufacturers use 31.5 psig

Swing compressors should reflect the capacities in both high and low stage on the energy balance. Condenser heat exchange surfaces should be examined to verify the heat transfer surface is clean of build-up and the water distribution is effective at covering the coils. We’ve learned from RETA’s Industrial Refrigeration Book 1 that as little as 1 / 32 of an inch scale on a condenser coil can reduce the capacity by as much as 30%. A reduction in condenser capacity will lead to higher discharge pressures and, therefore, higher compressor horsepower being required. Non-condensable gasses in the system can also cause higher discharge pressures and must be removed. Evaporators, chillers, and other heat exchange surfaces can become oil logged, reducing the effectiveness of the heat exchange surfaces. An effective oil management system compares additions and subtractions from the ammonia system. An effective oil management system can inform the owner if more

suction pressure and 151 or 181 psig discharge pressures to produce the high side compressor tonnage rating. If the suction and discharge pressures differ from the manufacturers design, then the tonnage rating of the compressor can be adjusted to show actual performance. As the suction pressure is lowered the compressor tonnage rating also drops. With a lower compressor capacity, the upstream heat transfer surfaces can become “backed-up” affecting the room and product temperatures. Heat of compression should also be calculated into the equation—(HP x 2545)/12,000. “While an energy balance can be a daunting task to compile, it should not be just a check in the box for your PSM program.”

oil is added than taken out through oil pots. If over a year there is a large gap between what has been added and what has been taken out, it most likely is still in the ammonia system somewhere. Does the system contain any evaporators that have had coil circuits pinched in the past? If so, the evaporator should be re-rated to show actual tonnage capacity. The basic energy balance can be difficult to put together if some of the equipment you own no longer has design data, or if the manufacturer no longer exists. It is the basis for evaluating if your system is sized correctly. It may show that you are short compressor capacity. This doesn’t necessarily mean that you should purchase another compressor. Processing facilities have fluctuating heat loads, the evaporator capacity may be greater than the compressor capacity on paper. Cows, pigs, turkeys, etc. cannot enter all cooler bays at once, it is a gradual heat load over time. A detailed energy balance should explain why a compressor capacity is lower than the evaporator capacity. One item we haven’t discussed is the heat load put onto the system. What is the total heat load that the refrigeration system has to absorb and reject? Lights, motors, people, wall and ceiling R-values, and infiltration loads need to be calculated to show that the evaporators are an appropriate size to handle the heat load. While an energy balance can be a daunting task to compile, it should not be just a check in the box for your PSM program, but a tool used to understand the actual performance.

SAFETY

WHAT DO I NEED TO DO? Under 10,000 Pounds of Ammonia:

By Kent Harmon, Industrial Consultants RETA Education Chairman

Compiling and updating the following information is essential to GDC compliance: • Process Safety Information (PSI), including current P&ID’s (NOTE: A crucial guideline to be considered is in IIAR Bulletin #110 - Section 4: Records); • Process Hazard Analysis (PHA) with discussion of potential release scenarios and their impacts; • operating procedures; • training; • pre-start up procedures; • mechanical integrity; • preventive maintenance; • hot work permit; • incident investigation; and • emergency actions, planning, and response. Everyone who deals with PSM knows they must comply with the fourteen elements. For those with less than 10,000 pounds, I like to say there are the nine elements they must comply with. Even though compliance can seem confusing, remember “How do you eat a whale? One bite at a time. Little bites will get you there.” Be compliant, be safe.

Bigger facilities that have over 10,000 pounds know that they have to comply with the OSHA-PSM standard. Facilities with less than 10,000 pounds sometimes do not know or understand what is required for them. When a facility has less than 10,000 pounds of ammonia in the facility system, both OSHA and EPA use their respective General Duty Clause(GDC) and or Recognized and Generally Accepted Good Engineering Practices (RAGAGEP) to inspect and generate citations. These clauses describe the responsibilities owners and operators have for being diligent in preventing chemical releases. This includes both an employer’s recognition of hazards — and —MOST importantly the industry’s recognition of hazards! The most prominent ammonia refrigeration consensus standards are issued by IIAR (IIAR Suite of Standards, most especially IIAR 2) and ASHRAE (Standard 15). Complying with a GDC basically involves the following: • identification and assessment of process hazards; • maintaining a safe process system; • minimizing consequences of any ammonia release; and • MOST IMPORTANT — adhering to industry codes and standards. (NOTE: This is commonly referred to as RAGAGEP.)

Thank You, Thank You, Thank You RETA Family

By Kent Harmon, Education Chair The RETA family had a very successful Conference in Hershey, Pennsylvania. A lot of RETA members do not know that RETA is an ANSI accredited organization, one of only about 60 organizations — in all disciplines, not just refrigeration — in the world. This makes belonging to RETA a very prestigious and extraordinary organization. However, for RETA to maintain this ANSI accreditation, all RETA study resources must be reviewed and updated every five years per our policies and procedures. As the Education Chairman, I had a goal of 100 volunteers on the Education Committees. At the end of Conference, thanks to members being willing to volunteer, the incredible RETA Board, Executive Committee, and RETA HQ we now have a total of 125 members. I know this sounds like a lot of committee members; however, RETA is now becoming a world-renowned organization. With the help of Bret Swanson, the Membership Chairman, RETA now has over 6,000 members and is

pushing into Australia, New Zealand, Canada, England, and France as well as other countries. TO MEET THE DEMAND OF REVIEWING THE MATERIALS WE NEED YOUR HELP Listed below are the current committees: • CO2 Study Course: A cooperative work with the North American Sustainable Refrigerant Council (NASRC). This book will address CO2 commercial and industrial systems • Industrial Refrigeration Controls: An update to the RETA controls books • Refrigerated Facility Energy Efficiency Study Guide: A study resource for the CRES Certification. This work is in its final stages and we hope to have it available in the near future • PSM: A more in-depth version of the Ammonia Refrigeration Compliance Guidelines. This will facilitate the creation of two new certifications — one for operators, one for managers

18 RETA.com

• Basic Electricity II: Periodic review • Industrial Refrigeration II: Periodic review • Video: Creating videos for RETA’s training library

• Voice over PowerPoints: For chapters without speakers and a virtual chapter for “At- Large” members without an accessible physical chapter • Spanish Industrial Refrigeration I: Periodic review (Spanish speakers needed) • Spanish Industiral Refrigeration II: Convert to Spanish (Spanish speakers needed) • RETA Authorized Instructor (RAI: Must be an RAI to participate) So here is my new goal: 200 committee members. Seems crazy, doesn’t it? Remember we have over 6,000 members, we just need 75 more volunteers. Here is your chance to give back to the organization and the industry that has given you so much. For just one hour a week, you too can join one of these prominent committees. If you have an interest in being a part of this important work, contact Kent Harmon, Education Chair at kentharmon@ammonia.com or Jim Price, Education Manager at jprice@reta.com. We look forward to hearing from you and to working with you on one of the committees.

58%, and CRES 1%. Many also earned RETA credentials that are now expired, including CARO (21%), CIRO (5%), Level A (7%) and Level B (2%). The CARO survey asked how RETA certification has impacted refrigeration system operations in their experience. Nearly 100 responded to this question by reporting: • Improved plant safety: 95%. • Improved plant efficiency: 86%. • Improved operator awareness of safety requirements: 83%. • Improved costs of plant operations: 76%. Over 350 survey comments demonstrate how certification addresses RETA’s Mission Statement “To enhance the professional development of industrial refrigeration operating and technical engineers.” They cited many benefits from RETA certification. • “RETA certification makes operators aware of dangers associated with the job.” • “RETA certification increased safety awareness across all experience levels.” • “Everyone at our plant has a better understanding of the hazards of ammonia.”

• “I ammore conscious of potential hazards. We take a proactive approach to mitigating hazards and follow PPE guidelines from our SOPs.” • “RETA certification has opened my eyes to energy saving opportunities.” • “Costs are lower because of greater knowledge of the refrigeration process.” • “RETA training helped me understand why safety requirements are in place.” • “RETA certification not only provides the basic knowledge for safety, but it creates a level of pride in following safe work practices.” • “RETA certification has made me more aware of how my decisions can impact the daily operating costs and maintenance costs of the refrigeration system.” • “RETA heightens awareness and support by executive management for preventive maintenance of all equipment and proper training of staff, which ultimately leads to safer, more efficient operations.” We welcome your questions about RETA’s credentialing exams and activities. Send your questions by email to Dan Reisinger at dan@reta.com

Manager, has guided development of RETA credentialing exams since 2002. RETA Testing Corner provides information and answers questions from RETA members, candidates and others to help them earn and benefit from RETA credentials. Each RETA credential is designed to measure the knowledge and skills needed to perform safely and effectively at that level. RETA recently conducted a new CARO Practices Survey to update the content areas that will be required to pass future CARO examinations and the number of questions that should be asked for each topic. Responses came from 158 people with 86 employers in 46 states and Canada (1). Of these, 67% have worked as system operators, 41% as supervisors, 19% have provided technical support and 15% have experience as refrigeration instructors or trainers. Ninety-nine percent of survey participants hold at least one current RETA credential: CARO 63%, CIRO

The Shade Tree Mechanic, Volume XXVIII

If I was mak’in the laws Ya know, there’s been a lot of talk lately bout them politicians and what they want to do.They all seem to know what they wanta do, even if they don’t do it. I gotta think what would I do if I were ta be elected ta be king bee.

The first thing would probably be ta outlaw rust. Now I know that rust happens. But that don’t mean that you have ta let stuff just sit and rust. I checked with that internet place and here is what I found. 5 gallons of paint for $37.99 I pay a lot more than that for paint around the shop. But what I’m sayin is paint is cheap. I don’t understand why people don’t paint stuff more often. I’ve gotta a lot of spray cans laying around the yard. I primer parts after they get cleaned. Valve bodies, quarter panels, spare pipe nipples, almost anything that will get painted in the end gets primed in my shop. Color don’t really matter. I paint ta prevent rust. Just get a coat on it! I walk through the plant and see brown and instantly think paint. I write more work orders for painting than almost anything else. What do ya think it woulda cost ta save this? Paint!That’s all it takes. Here is an R/S strainer that needs replacin cause no one ever painted it. I know what you’re

thinkin, it’s only a strainer and not that expensive. But in order to replace it, I need ta pump down the line. Production will need ta be down long enough to pump it down and replace it. How much confidence do ya think I’d Pump down, pipin replacement, etc. Most of the time, this is found through mechanical integrity inspections or annual inspections. Savin a few pipes justifies the costs of my inspections. At my plant, I use production labor have in the rest of the system? What do ya think this costs?

durin shutdown days to paint. I order pizza for the paintin crew, turn up the radio and everyone enjoys the day. Last summer we had some of our employees kids come in and paint while they were home from college. If I can save one major repair I can pay for years of paintin. I was talkin with a buddy the other day an he was talkin about a $200,000 repair because no one ever painted anythin. That should be a crime, an if I was in office it would be. The Presidential Mechanic, under the shade tree. LOL
