CO2 REFRIGERATION CASE STUDY: YOSEMITE FOODS

One of the largest Trascritical CO2 Refrigeration Systems in North America.

Modesto, California

Yosemite Foods Inc., in Modesto, CA, has been providing the highest quality specialty pork products to a diverse array of niche markets across the West Coast for over 30 years. This facility approached CoolSys to see if they could help them achieve a unique set of refrigeration and energy reduction goals for their new hog processing plant in Stockton, CA.

The Yosemite Foods Facility was designed to process 550,000 lbs. daily in 116,000 square feet of processing space, 95,000 square feet of which is comprised of refrigerated areas. After presenting and considering several options, CoolSys was contracted to provide a turnkey solution which included engineering,

design, equipment selection and procurement, and installation for this project.

Project Objective

Must be energy efficient, using “best-in-class” equipment
Must be safe; safety is paramount
Must be environmentally friendly
Must be able to reclaim heat; this is critical in the operation
Must be cost effective: initial purchase price of equipment along with cost of ownership with regards to maintenance, service, and energy consumption

The Solution:

CoolSys met the challenge and was able to satisfy all objectives put forth this facility. Utilizing CoolSys capabilities the facility’s refrigeration system now includes the largest trans-critical CO2 refrigeration system in North America with

a total of five compressor racks running 2,450 horsepower and 22.5 million BTUs/hour. This approach eliminated the need for an ammonia over CO2 system, satisfying the customer’s desire of using non-corrosive substances. Discharged heat from the compressors is reclaimed and redirected to generate hot water more efficiently, which is a critical requirement for the meat processing operation.
