Many food retailers, foodservice operators and OEMs are understandably confused about which refrigerants are acceptable for use in their respective businesses. After decades of complying with the regulations of the Environmental Protection Agency (EPA) and phasing out of CFCs and HCFCs, business owners, operators and technicians need to understand the recently passed regulations from the EPA that will cause them to move away from HFCs. In short, they need to know which refrigerants are acceptable to replace certain HFCs, which are not, and how much time remains until they need to comply.
Lowering the global warming potential (GWP) of refrigerants is a priority for the EPA. With an influx of synthetic refrigerants, plus a renewed look at some natural alternatives, this is an issue pertinent to so many in the industry. In this panel discussion, a real Who’s Who of industry experts will weigh in and discuss this timely topic. Be there to hear the latest from Dr. Rajan Rajendran, vice president — system innovation center and sustainability, Emerson; Dr. Samuel Yana Motta, director of technology, Honeywell International; Dr. Charles Allgood, technology leader for refrigerants, Chemours; and Matt Ritter, global business director, Arkema.
Cold Chain Evolution
Dean Landeche, vice president of marketing, retail solutions, Emerson
The demand for fresh and sustainable products continues to shape the foodservice and food retail markets. Consumers seek food chain transparency, requiring retailers to find ways to ensure traceability from “farm to fork.” But numerous processes, ownership transactions and logistics complexities have historically created a fragmented tracking environment. Meanwhile, the Food Safety Modernization Act is introducing new requirements for food quality, safety and integrity from retailers and their stores. Dean Landeche, Emerson’s vice president of marketing, retail solutions, will explore how retailers can respond to market and regulatory requirements and gain a competitive advantage by creating greater transparency. He will show how retailers can benefit from recent advancements in cold chain monitoring technology — not only to ensure freshness through improved protection of high-value perishable shipments, but also to utilize cloud-based tracking solutions to document the links of custody throughout the entire supply chain.

Utilizing Digital Retrofits to Achieve Capacity Modulation
Tim Uderman, lead technical sales manager, Emerson
Rob Southwood, director of sales, Emerson
Extending the shelf life of perishable items and preventing food shrink are top priorities for today’s supermarket operators. With limited compressor modulation options, most fixed-capacity refrigeration racks make it difficult to achieve the tight control over suction pressures needed to improve case temperature precision and reduce compressor cycling. Thus, many operators are turning to digital retrofits to solve this problem. Retrofitting a digital compressor to serve as the lead compressor in a fixed-capacity refrigeration rack allows the rack to modulate from 10 to 100 percent to precisely match the capacity of changing refrigeration loads. Emerson’s Tim Uderman, lead technical sales manager, and Rob Southwood, director of sales, will discuss various methods of compressor modulation and help you decide which type is best for your application. He’ll also explore the role of Copeland™ digital compressor technology in a digital retrofit and explain the controller options in these systems.
CO2 Booster Systems From a Service Mechanic’s Perspective
Andre Patenaude, director — CO2 business development, Emerson
The adoption of CO2 booster systems has increased significantly in recent years as operators look for a natural alternative to high-GWP HFC systems. But servicing a CO2 system requires refrigeration technicians to first gain a keen understanding of the refrigerant’s unique operating properties. As Emerson’s director of CO2 business development, Andre Patenaude will discuss the key servicing considerations of a CO2 booster system, including: low critical point, high triple point and high pressure. In addition, Andre will present strategies for dealing with standstill pressures, from managing pressure reliefs and power outages to mitigating risks. He will also examine some emerging methods being deployed to improve the viability of CO2 systems in warmer climates, such as: spray nozzles; adiabatic gas coolers; parallel compression; sub-cooling; and ejectors. Attendees will also learn about some the peculiarities of working with CO2 systems that differ from traditional HFC-based systems.
