CTA’s refrigeration group is a U.S. leader in next-generation “natural” refrigeration systems. CTA is involved in several projects using natural refrigerants and has also designed and commissioned the first supermarket to use 100% natural refrigerants in the U.S. Through our involvement with the U.S. Department of Energy, National Renewable Energy Lab, and the U.S. Environmental Protection Agency, we’re helping to advance the knowledge of how these next generation systems perform and can be applied. The result is CTA’s invaluable ability to help end users make the tough decisions that are right for the environment and for their business by helping them select, implement, install and maintain the system that is right for them now and in the future.
