Description
Description
A walk-in cooler normally requires a remote condenser, an evaporator, and refrigerant piping between them. The MRCOOL 12,000 BTU Compact Refrigeration System MMFDW12D simplifies that system, featuring a packaged, horizontal cabinet that mounts through the wall, with no on-site refrigerant piping to connect. The inverter-driven compressor ramps up for fast pull-down, then slows to maintain temperature efficiently.
Inside the box, you can hold temperatures from 0 to 50 degrees F, from chilled beverages down to near-freezing storage. Outside, the system operates in ambient temperatures from 5 to 113 degrees F, so it can work on a wall facing a hot loading dock or an unheated outbuilding. The galvanized steel cabinet has an epoxy coating to resist corrosion and an IPX4 rating against splashing water.
Key Features and Benefits of the MRCOOL 12,000 BTU Compact Refrigeration System
- Cooling Capacity: At 12,000 BTU, this 1-ton system can serve large walk-in boxes and features a max motor blower speed of 1,900 RPM.
- EVI Inverter: The EVI DC inverter rotary compressor adjusts output to the load, supporting low startup current and efficient partial-load operation.
- Hot Gas Defrost: System heat clears frost, and the method is up to 50 percent more energy efficient than standard electric defrost, reducing time spent thawing.
- Control Options: Wi-Fi and the MRCOOL Connect App let you monitor status and receive cooling-failure alerts remotely; the wired controller provides on-site control.
- Controller Functions: The MMFDW12D's wired controller offers forced cooling, manual defrost, screen lock, and an adjustable thermostat to manage operation.
- Refrigerant Charge: The R-32 refrigerant has lower global-warming potential than other formulas, while still providing the cooling performance your cold storage needs.
- AWEF Rating: At medium temperature, the 8.1 AWEF rating gives you a benchmark for comparing annual energy performance.
- Fan Airflow: Inside airflow reaches 1,036 CFM; outside airflow is 942 CFM.
- Noise Ratings: Noise is rated at 66 dB on the interior side and 76 dB outside.
- Safety Listings: This model is UL and CSA certified and has ETL and cETLus listings.
Does the MMFDW12D Fit Your Walk-In?
In cooling mode, the MRCOOL 12,000 BTU Compact Refrigeration System handles cold boxes up to 11 x 11 x 8 feet (L x W x H), with walls insulated to at least R-25. Preservation mode supports up to 416 cubic feet with R-32 minimum insulation. The system itself measures 38.58 x 28.15 x 21.65 inches (L x W x H) and weighs 180 pounds, so frame your wall opening to carry that load. For wiring, you need a 208/230-volt single-phase circuit with a 14.9-amp minimum circuit ampacity and a 25-amp maximum breaker.
Sylvane's Expert Take
This system suits restaurant kitchens and farm operations installing or renovating a walk-in on an exterior wall. Keep the exterior side away from patios and bedroom windows. For overnight inventory, prioritize cooling-failure alerts and hot gas defrost, which frees the system to return to cooling quickly. Choose this refrigeration system when remote status checks and variable output fit your cold-storage workflow.
