The DQ Series are ceiling-mounted industrial, walk-in evaporators equipped with 31.5″ (800mm) high-efficiency industrial fans.

DQ units are dual-coil construction with the airflow coming down from the evaporator through the fans. This allows for direct down-flow on specific applications. Fans draw air from the evaporator coils and discharge it vertically through the fan guards underneath the module. The air defrost model (DQA) is designed for cold rooms above +34oF (1oC), whereas all other models (DQE, DQG, DQH, DQR and DQT) are for cold rooms or walk-in freezers from +25oF to +34oF (-4oC to 1oC).

Each unit is fully customizable and includes a wiring diagram that meets the customer’s requirements. The wiring diagram displays all the components with all the necessary protections and controls. DQ evaporators are available with an optional Guardian+ RC-S Smart Defrost controller for a trouble-free operation.

DQ evaporators have excellent sound levels, as low as 42 dBA at 30 feet from side of unit (for one fan model at low speed). They are ideal for refrigerated warehouses and corridors.
