Medium Capacity Packaged Refrigeration Unit for Walk-in Coolers & Freezers

Medium capacity packaged (monoblock) refrigeration units are integrated all-in-one cooling systems tailored for standard-sized commercial walk-in coolers and freezers. Every core component—compressor, air-cooled condenser, evaporator coil, expansion valve, fan set and microcomputer control box—is fully pre-assembled, pressure-tested and pre-charged with refrigerant at the factory. Eliminating on-site copper pipe welding, vacuum pumping and refrigerant filling, it drastically shortens construction cycles for catering, retail and food wholesale cold rooms.

Through-the-wall type: Simple ground-level maintenance, ideal for restaurants and central kitchens

Rooftop type: Saves all internal storage space, preferred by supermarkets and food wholesale shops

True Plug-and-Play Installation

Only wall/roof opening cutting, unit fixing and power wiring are required. Full installation can be completed within 1–2 days, cutting labor and engineering costs by over 60% versus traditional split refrigeration systems.

Dual Temperature Versions Available

Medium temp walk-in cooler: Maintain 0°C ~ +5°C for fruits, vegetables, dairy, beverages and cooked food

Low temp walk-in freezer: Steady -18°C storage for meat, seafood, frozen food and ice cream

Standard refrigerant R404A; R507, R290 eco-friendly alternatives are optional.

Dual Defrost Modes Optional & Full Safety Protection

Standard electric defrost; energy-saving hot gas defrost for high-frequency usage scenarios. Built-in comprehensive protections: high/low pressure, compressor overload, phase loss, overheat and anti-freezing protection to avoid unexpected downtime during long-hour continuous operation.

Optimized Operation Noise & Durability

Reinforced unit cabinet and silent fan design reduce running noise, suitable for indoor commercial environments. IP54 waterproof and dustproof casing adapts to humid kitchen and warehouse conditions.

Typical Application Scenarios

Medium-sized restaurant central kitchen walk-in coolers & freezers

Supermarket backroom food storage cold rooms
