Product overview
MRCOOL 12,000 BTU Compact Refrigeration System - R32
The MRCOOL® Compact Refrigeration System is an all-in-one cooling solution designed for small to mid-size walk-in coolers, cold storage spaces, and specialty refrigeration applications. By integrating the evaporator, condenser, compressor, and controls into one compact cabinet, it delivers dependable performance with a simplified installation footprint.
Built with advanced DC inverter technology and variable frequency control, this system adjusts output based on demand to maintain steady temperatures while improving energy efficiency. Low startup current, BLDC fans, and a high-pressure centrifugal blower help provide quiet, consistent performance across ducted layouts and multiple small-zone applications.
Its compact horizontal design makes it ideal for tight or unconventional spaces, while the galvanized steel cabinet with epoxy coating helps resist corrosion in demanding commercial environments. Integrated hot gas defrost, intelligent protection features, and hybrid power compatibility add reliability, efficiency, and flexibility.
With WiFi connectivity through the MRCOOL® Connect App, you can monitor and control the system remotely, receive alerts, and manage updates from a smart device. A wired controller is also included for centralized on-site control.
Using R-32 refrigerant, this system provides strong cooling performance with a lower global warming potential than many traditional refrigerants. It is a smart, efficient choice for food service, agriculture, hospitality, manufacturing, florals, pharmaceuticals, dairy, beverages, and other specialty storage needs.
