Product Description

MRCOOL® Compact Refrigeration System, 12K BTU

The MRCOOL® Compact Refrigeration System is an all-in-one unit that integrates the evaporator, condenser, compressor, and controls into a single cabinet for maximum efficiency and convenience. Designed for applications from cold storage renovations to custom walk-in coolers, it delivers dependable performance with DC inverter technology and variable frequency control, giving smooth operation, low startup current, and wide capacity adjustment for fast cooling or efficient partial-load operation.

BLDC fans and a high-pressure centrifugal blower maintain quiet, precise temperature control, while integrated hot gas defrost provides quick, efficient defrosting. Hybrid power compatibility (DC direct power input) reduces utility costs and adds energy flexibility. The horizontal configuration and compact size fit tight or unconventional spaces, and the epoxy-coated galvanized steel cabinet resists corrosion.

Wi-Fi connectivity through the MRCOOL® Connect app provides remote monitoring, control, alerts, and software updates, and a wired controller centralizes system control. R-32 refrigerant offers strong cooling performance with lower global-warming potential.

Backed by a 1-year parts, 3-year compressor, and 1-year unit replacement warranty.

Professional installation by a licensed refrigeration/HVAC technician is required.
