Remote Refrigeration Units

Remote Refrigeration Units for Walk-Ins

Remote refrigeration units house the compressor and condenser away from the refrigerated equipment they serve. These walk-in refrigeration systems remove heat and compressor noise from kitchens, dining areas, and retail spaces, as they are installed on rooftops, exterior walls, or in mechanical rooms. Remote refrigeration is common in walk-in coolers, walk-in freezers, and other commercial refrigeration systems.

8 Key Buying Specifications for Remote Refrigeration Units

Remote refrigeration units vary by compressor horsepower, temperature range, refrigerant type, electrical configuration, operating features, and installation requirements. These specifications influence performance and regulatory compliance.

1. Compressor HP: Compressor capacities range from 1/3 HP to over 7-1/2 HP. Smaller units support reach-in refrigerators and display cases; larger models serve walk-in coolers, walk-in freezers, and multi-evaporator systems.
2. Temperature Range: Medium-temperature units can maintain refrigerated environments around 35°F (1.667°C). Low-temperature models support freezer applications.
3. Refrigerant Type: Common refrigerants include R-404A, R-448A, and R-449A. Many new installations favor R-448A and R-449A because of their lower environmental impact and improved regulatory compliance.
4. Electrical Phase: Single-phase units are common in restaurants and small retail operations. 3-phase models support larger refrigeration systems that require greater cooling capacity and motor efficiency.
5. Special Features: Electronic defrost controls, scroll compressors, and head-pressure control systems improve efficiency, reliability, and performance in varying ambient conditions.
6. Refrigerant Line Length (Line Set): Most remote refrigeration systems support line runs of between 15 ft (4.572 m) and 100 ft (30.48 m). Always verify manufacturer recommendations before finalizing equipment placement.
7. Ambient Temperature Rating: Outdoor condensing units should be rated for the highest expected ambient temperature. Prefer high-ambient models for hot climates and demanding commercial environments.
8. Certifications: UL and cULus listings verify electrical safety. Refrigerant installation and service must comply with EPA Section 608 requirements. Verify all local and state refrigerant regulations before installation.

How Does Remote Refrigeration Work?

Remote refrigeration separates the cooling system into 2 connected sections. The evaporator remains inside the walk-in, while the condensing unit is installed in a separate location.

Refrigerant absorbs heat inside the refrigerated space and carries it to the remote condensing unit through insulated refrigerant lines. The condenser then releases that heat outdoors or in a mechanical room before sending cooled refrigerant back to the evaporator.

Remote refrigeration systems discharge heat outside the occupied area, maintaining lower kitchen temperatures and quieter working conditions compared to self-contained refrigeration systems.

Self-Contained vs. Remote Refrigeration Units

Self-contained and remote refrigeration systems differ in installation requirements, operating conditions, and long-term performance. Remote systems offer quieter operation and lower heat load, while self-contained systems provide simpler installation and lower upfront costs.
