Products
A+ Series® Air Coolers - Industrial Air Coolers - A+R
Above-Rail Evaporator
Designed specifically for food processing rooms where cleanability, worker comfort, and usable workspace are critical, Colmac Coil A+R Air Coolers use an above-rail configuration to keep refrigeration equipment overhead while providing effective air distribution throughout the conditioned space.
Available in both standard and low-profile configurations, the A+R combines hygienic materials, full access to the coil core, low installation heights, and optional Clean-In-Place technology to support demanding food processing and washdown environments.
Standard A+R units are available in capacities from 3 to 25 TR with 1–8 fan configurations.
The A+R is purpose-built for refrigerated processing spaces where sanitation requirements, employee comfort, equipment access, and available workspace all influence evaporator design.

Standard and Low-Profile Configurations
A+R Standard
A+R Low Profile
Developed for processing spaces with extremely limited overhead clearance, the A+R Low Profile reduces overall installation height while maintaining the hygienic above-rail concept.
Installation height: approximately 20–30 inches
Fan rows: 2–6
The low-profile configuration uses 1/4 hp bolted 48-frame motors and is available for applications where minimizing equipment height is the primary design constraint.
