Industrial Refrigeration

Industrial refrigeration provides cooling for large scale processes. Ammonia systems are a well established solution for industrial refrigeration due to their superior energy efficiency and ability to chill to very low temperatures.

Ammonia has been used in the industrial refrigeration market for many decades. Recently developed low change ammonia systems are helping to address safety concerns. Propane and carbon dioxide are also used for cold storage applications with popularity increasing for cascade systems using carbon dioxide and ammonia.

Alaska-based Denali Brewing and Spirits has completed the commissioning, site training and startup of its PROGreen CO2 (R744) chiller from U.S. manufacturer Pro Refrigeration; it is one of the first CO2 process cooling chillers installed in the U.S.
Plans for the installation at the brewery were first announced in May, following a year of research, development and engineering. The installation was done by Pro Refrigeration and Denali’s service contractor, Arctic Refrigeration. Additional remote support was provided by South African consultancy Future Green Now (FGN).
Pro Refrigeration’s 100 HP PROGreen CO2 chiller replaces Denali’s HFC-blend-based 40HP PROChiller System, also from Pro Refrigeration, which was installed in 2013.
This system provides up to 1,000,000 BTU/HR cooling capacity to support Denali Brewing Company’s new product line while also making use of onboard heat recovery to support the distillery’s building and water heating needs.

The ECOFLEX Industrial Chiller family offers a compelling alternative for industrial refrigeration by using cold water/glycol and confining the R-717 refrigerant within the rack structure, eliminating the need for its installation inside the refrigeration room.
The system includes open screw-type Bitzer compressors and shell-and-plate type chillers. By confining the ammonia refrigerant within the rack structure, the system minimizes the risk of ammonia exposure in the facility, enhancing safety and environmental compliance.

It can achieve capacities of up to 400 tons of refrigeration per group, with each compressor handling up to 200 HP.
