Split Refrigeration Units For Walk-Ins

Split-Pak Remote Refrigeration Systems used in walk in cooler refrigeration unit. Also referred to as split refrigeration system and remote refrigeration system.

Norlake's Split Pak™ split refrigeration units for walk-ins feature a condensing unit with matching evaporator coil. With split, or remote, refrigeration systems, the condensing unit is located away from a walk in cooler or freezer, usually outside a building or on a roof, while the evaporator coil is inside the walk in.

Split-Pak models should be used when:

  • Larger capacity systems are needed
  • Height above the walk-in is restricted
  • Taking the heat outside and removing load from the HVAC system is important
  • Lower noise level inside the space is important
  • Un-chilled product is loaded into a walk-in and needs to be pulled down to the appropriate storage temperature
  • You expect frequent walk in door openings

Featuring eco-friendly R449A refrigerant, Norlake's split refrigeration units for walk-ins are pre-piped and pre-wired for quick and easy installation. Many Split-Pak systems are equipped with scroll compressors for maximum energy efficiency, increased reliability and quieter operation. Units that are six H.P. and above used in freezer applications are equipped with an electronic controller system as standard. Evaporator coils are low profile and ceiling mount for minimum loss of working space.
