Colmac Coil Manufacturing, Inc.

Look at these four state-of-the-art 50.1 TR A+P Fully Insulated Penthouse Units with pitched bases, custom-built for a CO2 cold storage facility. The pitched bases, shipped pre-installed, eliminate the need for a separate curb and allow for seamless installation on a pitched cold storage roof. These units are designed to maintain a consistent 35°F across both the dock and mezzanine, covering a total area of 36,007 square feet. Congratulations to AMS Industries, Inc. on a successful installation! We were honored to partner with them on this innovative project. #co2refrigeration #coldstorage #refrigeration #coldchain

We’re excited to share a recent CO2 project for a pretzel company in the Midwest! These custom-designed A+Series? A+P Dual Coil Roof-Mounted Enclosed Penthouse Air Coolers feature DX coils and hot gas defrost, engineered for a cold storage distribution center. Why Dual Coil Design? ? High Capacity: Delivers large cooling capacities to meet demanding applications. ? Built-In Redundancy: Allows one evaporator to defrost while the other remains operational. ? Isolated Operation: Each coil is fully isolated with four access doors provided in freezer applications. To further enhance performance, Colmac Coil supplied custom ducting to optimize airflow, shipped separately for seamless on-site installation.

Check out these A+L Air Coolers designed for a dairy processing facility with a flooded ammonia refrigeration system. Each unit was pressure-tested and nitrogen-charged at the factory, ensuring they arrive on-site ready for reliable performance. To protect product quality during transit, the units were securely shrink-wrapped using durable 8.5-mil plastic. This heavy-duty wrap withstands fluctuating weather conditions without losing its shape, ensuring the air coolers reach the job site in the same condition as when they left the factory.
