Industrial refrigeration systems primarily use ammonia as a refrigerant. It is 100% natural, does not harm the environment, and is the most energy-efficient refrigerant available. Through an intricate system of specially designed pipes, gases are compressed, transported, modified, and distributed to create the cool air that your system needs.

We understand the considerations that are involved with using ammonia and have the experience designing, installing, and maintaining industrial ammonia refrigeration systems. If you need to add a new ammonia system or replace/update one that’s existing, we can help you design a new process safety management program or revamp your current one to ensure you’re in compliance.

Our team utilizes various methods of process refrigeration to help you achieve your product manufacturing objectives and maintain precise production conditions. For mission critical processes that require temperature control, our system design, installation, and maintenance can help maximize your uptime. In case of a problem, our certified service technicians are available for 24/7 emergency response.
