About this product

The MRCOOL® Compact Refrigeration System is an all-in-one system that integrates the evaporator, condenser, compressor, and controls into a single cabinet for maximum efficiency and convenience. Designed for diverse applications—from cold storage renovations to custom walk-ins—it delivers dependable performance with advanced DC inverter technology and variable frequency control. This enables smooth operation, low startup current, and wide capacity adjustment for fast cooling or high-efficiency partial-load performance. Equipped with BLDC fans and a high-pressure centrifugal blower, it maintains quiet, precise temperature control. Meanwhile, its integrated hot gas defrost provides quick and efficient operation, and hybrid power compatibility reduces utility costs and adds energy flexibility. Designed for quick and versatile installation, this refrigeration system’s horizontal configuration and compact size allows it to fit into tight or unconventional spaces. Its galvanized steel cabinet with epoxy coating resists corrosion, while safety features—intelligent defrost, and multi-layer protection—ensure reliable operation across food service, agriculture, manufacturing, and hospitality environments. Smart connectivity through WiFi and the MRCOOL® Connect App provides fully-remote monitoring, control, alerts, and software updates from any device, with a well-established wired controller to centralize system control. Sustainability is built in: the MRCOOL® Compact Refrigeration System uses R-32 refrigerant, offering strong cooling performance with a lower global-warming potential. The result is a forward-thinking, energy-efficient refrigeration solution that combines intelligent control, durable construction, flexible installation, and eco-friendly design—delivering powerful, reliable cooling and long-term value for modern homes and businesses, all backed by a 1-year parts, 3-year compressor, and 1-year unit replacement warranty.
