The ABY-GBY series are large V-shape industrial CO2 gas coolers available in an array of sizes. They are equipped with 31.5″ (800mm) high-efficiency fans. Headers are made of stainless steel tubes. Available voltages are 208-240/3/60, 480/3/60 or 600/3/60.

Big-V gas coolers are extremely robust and reliable. They are specifically designed to withstand severe weather conditions, including heavy snow and high winds. Their V-shape configuration allows for a slightly smaller footprint without compromising capacity.

Each unit is individually designed for a specific job. It includes a control box and a wiring diagram that meets the customer’s requirements. The wiring diagram displays all the components with all the protections and the necessary controls. The unit comes without any controls. Fan cycling must be managed by the building’s refrigeration system through a controller such as Micro-Thermo, CPC or others.

The ABY-GBY Series have been specifically developed to satisfy a wide variety of applications in commercial and industrial refrigeration sectors as well as in air conditioning.

The selection of a gas cooler can be a complex task, for this reason we recommend you contact one of our qualified technical representatives  for assistance.

From an environmental stand point, CO2 is a superior alternative to environmentally-damaging hydrofluorocarbons (HFCs). It is also non-flammable, non-toxic, and less expensive. Learn more about RefPlus CO2 technology.
