Refrigeration

Built for licensed contractors and property managers, our commercial refrigeration category includes Condensers Freezer & Cooler and Evaporators Freezer & Cooler. These components are ideal for building or servicing walk-in cooler/freezer systems, performing replacements, and standardizing fleets across multiple locations.

Size by load, not by guesswork. Match BTU capacity and tonnage between condenser and evaporator, account for box size, insulation, design temperature, ambient, and line length. Refrigerant options include R-404A for low-temp freezers and R-410A for many medium-temp coolers. SEER2 and HSPF2 ratings don’t apply to commercial refrigeration; prioritize BTU/tonnage, refrigerant, evaporator TD, and the required Freezer operating mode.

Designed for light commercial duty and budget control, this equipment spans approximately $2,199-$6,072, delivering dependable temperature holding with professional installation. A licensed technician is required for evacuation, charging, and commissioning to manufacturer specifications and local code.

Frequently Asked Questions

  • What is the difference between a freezer condenser and an evaporator in a walk‑in system?

    The evaporator absorbs heat inside the box; the condenser rejects that heat outdoors. Both must be capacity- and refrigerant-matched.

  • How do I choose between R-404A and R-410A refrigeration equipment?

    Use R-404A for most low-temperature freezers and R-410A for many medium-temperature coolers. Always match the existing system and design conditions.

  • Are these condensers and evaporators suitable for walk‑in freezers vs. coolers?

    Yes. Select models designated for low-temp (freezer) or medium-temp (cooler) operation and match capacity, refrigerant, and defrost type.

  • What sizing information do I need to match a condenser to an evaporator?

    Provide BTU at design temp, box size/insulation, desired box temperature, ambient, refrigerant, voltage, line length, and defrost preference.

  • Do these refrigeration components require professional installation and refrigerant charging?

    Yes. A licensed technician must evacuate, charge, and commission the system to specified superheat/subcooling and code requirements.

  • Can RDI Systems equipment be used to replace existing components in commercial coolers?

    Often yes. Match BTU/tonnage, refrigerant, voltage, airflow configuration, and defrost method to the existing system and box load.

  • Do SEER2 or HSPF2 ratings apply to these products?

    No. Commercial refrigeration is not rated by SEER2/HSPF2; focus on BTU capacity, evaporator TD, and application temperature.

  • What defrost options are available for freezers and coolers?

    Low-temp freezers typically use electric or hot-gas defrost; medium-temp coolers often use off-cycle defrost. Choose per application.

  • How do I verify I have the right “Freezer operating mode” equipment?

    Confirm the target box temperature range, refrigerant, and defrost type. Select models labeled for low-temp when serving freezers.

  • What maintenance helps ensure reliable performance?

    Keep coils clean, verify fan operation, check TXV/EEV settings, inspect for leaks, and confirm proper superheat/subcooling periodically.
