The LQ Series are large ceiling-mounted industrial low-velocity walk-in evaporators equipped with 31.5″ (800mm) high-efficiency industrial fans. Some available models are AWEF registered.

Units are dual-coil construction for an air distribution towards the centre of the cooler or freezer. Fans draw air from below the unit and discharge it through the evaporator coils on both sides of the unit. LQ units are recommended where direct airflow on products or workers is a concern. The air defrost model (LQA) is designed for cold rooms above +34oF (1oC), whereas all other models (LQE, LQG, LQH, LQR and LQT) 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. It is available with an optional Guardian+ RC-S Smart Defrost controller for a trouble-free operation.

LQ 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, laboratories, pharmaceutical rooms, drip rooms and refrigerated corridors.
