Industrial Ammonia Refrigeration

Food Processing, Space Cooling & Freezing

Our team of professional engineers and project management staff are specialized in food processing plants, bakeries, poultry plants, beverage manufactures, produce plants, cold storage facilities, food distributors, ice facilities, ice rinks and arenas, dairy plants, and meat processing plants. We have designed and project managed all types of compression systems from single-stage to multi-stage systems for our customers. No matter if your facility needs cooling for production areas, loading docks, cold storage spaces, spiral or blast freezing, mid-temp coolers, or fluid cooling we’ve got you covered. We believe in establishing relationships with our customers and make sure day-to-day operations are seamless. Customer satisfaction and safety is always our number one priority.

For more than 50 years we have engineered, installed, and maintained NH3 systems. With our group of professional engineers and certified pipefitters, we design new facilities, additions, and remodels for all ammonia systems. We have state-of-the-art estimating equipment and can always provide timely quotes.


Our experienced crew has undergone specialized certification to install high pressure steel pipe. Safety is always number one; our qualified technicians go through hazmat and fit test training annually. Some of our pipefitters are instructors at local technical colleges for apprentice pipefitters. We know piping!
