OMZ condensing units are part of the Evolution Series. They are large, vertical discharge, air-cooled condensing units available in multiple configurations. These industrial units are specifically designed to provide cooling to other equipment and systems that incorporate evaporators (and associated expansion valve control systems).

They are factory-assembled units that consist of an air-cooled condenser, one or more Copeland scroll heavy-duty compressors and interconnecting pipe work. They also can include liquid receivers, filter driers, oil separators, shut off valves and related controls. Base and weatherproof housing are made from heavy-gauge galvanized steel. Unit design follows the best combination of energy efficiency, reliability, serviceability, and cost effectiveness. They are equipped with low-noise, high-efficiency 20″ (500mm) industrial fans.

Each condensing unit can be individually designed for a specific job. Each unit 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 can be supplied with mechanical or electronic controls.

These air-cooled condensing units can be used in a variety of commercial and industrial cooling applications, including cold rooms and warehouses, refrigerated display cabinets, restaurant equipment, temperature controlled food preparation areas, and for air conditioning systems.
