Want to Future-Proof Your Refrigeration System?


Look no further! Join the North American Sustainable Refrigeration Council (NASRC) for a FREE overview of natural refrigerants hosted by the Idaho Department of Environmental Quality (DEQ). Whether you work in a large or small-store format, this event is perfect for you. 

Associated General Contractors Building
1649 Shoreline Dr #100
Boise, ID 83702

Thursday, May 3rd, 9am-5pm
Networking Social 5-7:30

Hear about the many refrigerant-related challenges the food retail industry faces and how to avoid them. Learn how natural can refrigerants give you a competitive advantage over others.

The morning session will give an overview of future government regulations and policies related to your refrigerant choices. In the afternoon, choose one of two tracks:

Track 1: Deep Dive On Natural Refrigerant Systems

  • CO2 transcritical, ammonia, and   propane systems
  • How to optimize design, installation, operations, and maintenance of these systems

Track 2: Solutions For Smaller Food Retail Formats

  • CO2 condensing units and propane self-contained systems
  • Service tech availability, codes and standards, and return on investment for natural refrigerants

Attendees will hear from the nation's expert on refrigerant regulations and policy, as well as experts from the country's leading engineering and manufacturing firms specializing in CO2, ammonia, and propane technologies.

This event is ideal for food retailers from large chains to small independents and convenience stores. 

Light refreshments and lunch - sponsored by Kysor Warren - will be provided. A networking social sponsored by DC Engineering will follow the workshop. 

Registration is required. Space is limited, so don't delay!

Despite the advancement of natural refrigerant-based technologies in North America, many end users area still facing challenges when searching for qualified contractors and technicians to install and service the technology. 

That is why the North American Sustainable Refrigeration Council (NASRC) is thrilled to announce the launch of our new service network designed to help end users connect contractors and service technicians who are trained to install and service natural refrigerant systems.

The network is free and easy to use for both contractors and end users. The NASRC is optimistic that this will help end users overcome the challenge of finding a qualified contractor or service technician for their system. Read more about the launch here

California Senator Introduces California Cooling Act


NASRC and EIA are celebrating the introduction of the California Cooling Act, which was introduced by Senator Lara on February 7th. The Act will not only move the California Air Resource Board to proceed with regulations to reduce emissions of hydrofluorocarbon (HFC) refrigerants, but it also proposes a new incentive program to support California businesses and residents as they adopt low-global warming potential (GWP) refrigerants.

The NASRC held a natural refrigerants seminar focused on both the barriers and case studies of successful projects. The seminar was held in two half-day sessions on July 17th, 2017,  at the DC Engineering offices in Meridian near Boise, Idaho. Over thirty representatives from the supermarket refrigeration industry attended, including retailers, such as Albertsons and Whole Foods, as well as contractors, consultants, utilities and local state agencies.

Attendees received an overview of the environmental impacts of supermarket refrigeration, which are largely due to refrigerant leaks. Keilly Witman, formerly of the EPA GreenChill Partnership, presented and the policies and regulations that have been put in place by the government to mitigate these impacts.

Government regulations are just one of many hurdles that supermarkets face when considering natural refrigerant systems and equipment. Danielle Wright, Executive Director of NASRC, provided an overview of the primary barriers such as first costs, availability of service and codes and standards. These are hurdles that NASRC is taking action to overcome.

Case studies were presented by DC Engineering and CTA Group. The projects featured various types of system architectures including CO2 transcritical, CO2/Ammonia cascade and CO2/propane cascade systems. Additionally, a small format store with CO2 transcritical with integrated HVAC for both cooling and heat reclaim. The presentations focused on the energy impacts, design considerations and lessons learned from each project.
