Commercial and industrial refrigeration system engineering has been a highly regarded core competency at CoolSys Energy Design and its predecessor companies for over 40 years. Whether it is a supermarket, refrigerated food processing plant, restaurant, or cold storage, we can provide the engineering expertise to ensure optimized life cycle cost, environmental sustainability, practicalities, and a highly reliable effective design.

CoolSys Energy Design has pioneered some of the most innovative, sustainable, and cost-effective refrigeration designs operating today worldwide, including low-GWP and natural refrigerant systems.


  • Complete system refrigeration design from conception through construction documents including refrigeration system controls and leak detection
  • Low-GWP refrigerant design including CO2, A2L, and other sustainable refrigeration technologies
  • Evaluation and computing of heat load and optimum capacity requirements
  • Development of optimum capacity control algorithms
  • Installation oversight and supervision
  • Commissioning and performance verification
  • Experience and knowledge of the refrigerant industry resulting in the best application solutions


CoolSys Energy Design believes that low-GWP refrigeration systems, like transcritical CO2 systems, are a great option to consider for ground-up and remodel projects. CO2 refrigeration systems are a natural, low global warming potential (GWP), sustainable, and non-toxic alternative to using synthetic refrigerants. With a GWP of 1, CO2 systems enable you to get ahead of the mandates for environmental protection and “future-proof” your systems. Increasing equipment options and contractor familiarity, decreasing manufacturing costs, and continuing technological advances are making CO2 refrigeration systems more viable than ever before.

There are pros and cons to evaluate for every refrigeration design and there is no one-size-fits-all solution, but our refrigeration design experts not only stay up to date but ahead of the curve regarding new refrigeration technologies and regulations so that we can guide clients and help find the best design for your specific building and needs.No matter the right sustainable refrigeration solution, CoolSys Energy Design is here to help.
