A+ Series® Air Coolers - Industrial Air Coolers - A+D
Low-Profile Dual Discharge Evaporator
Designed for refrigerated work rooms and product storage applications where low air velocity, limited ceiling height, and product protection are critical, Colmac Coil A+D Air Coolers combine a low-profile cabinet with dual-discharge airflow for uniform cooling throughout the space.
Available in capacities from 2 to 40 TR, the A+D is especially well suited for highly perishable products that can be sensitive to high air velocities and excessive moisture loss. Low-noise fans with high-efficiency motors provide dependable airflow while supporting a comfortable working environment.
Each A+D is custom engineered around the refrigeration load, room conditions, working fluid, airflow requirements, and installation constraints of the application.
The A+D distributes conditioned air from both sides of the unit, providing broad room coverage while maintaining relatively low discharge velocities. This makes it an ideal solution for processing and storage environments where conventional high-velocity airflow may be undesirable.
