Dual Discharge Air Cooler
Low-temperature fresh-keeping storage, food processing, sorting & packing rooms, corridors.
- Two-way Airflow
What The Dual Discharge Air Cooler Does
Howcool Dual-Discharge Air Coolers (two-way airflow evaporators) are designed for long, narrow cold-rooms where single-direction airflow cannot reach both ends. Fans are mounted in the centre of the unit and discharge air simultaneously left and right, ensuring uniform temperature distribution across the entire room.
Widely used in corridor-shaped cold storage, processing-line chillers, logistics warehouses with long aisles, and fruit/vegetable CA rooms. Same spray-molded construction, internally-threaded copper tubes, hydrophilic aluminum fins and low-noise external-rotor motors as our standard D-type evaporators.
Perfect for low-temperature fresh-keeping storage, food processing, selection and packing rooms, anterooms and corridors. Built to enhance your cooling experience with balanced two-way airflow and even temperature distribution.

Why Buyers Choose This Model
Two-way Airflow
Fans in the middle, air discharged to both ends. Temperature uniformity ±0.5℃ across rooms up to 40m long.
Long-Room Coverage
Ideal for 20-40m long cold storage rooms where single-direction evaporators would create hot/cold spots.
Robust Construction
Spray-molded galvanized-steel casing, stainless-steel drain pan, integrated defrost drain heater prevents ice build-up.
Air Cooler / Evaporator Failure Modes
Uneven temperature across the room
Cubic evaporators from 5 to 200 kW and dual-discharge coolers sized to throw air the full depth of the chamber.
Ice build-up and lost capacity
Defrost method matched to room temperature — electric for freezers, off-cycle for chillers.
Wasted floor area
Two-way airflow units mounted centrally cover both sides of a corridor layout from one position.
