Split-Pak A2L™ Remote Systems

HIGH QUALITY, ENERGY-SAVING COMPONENTS SIZED TO FIT YOUR SPECIFIC REQUIREMENTS

Master-Bilt is leading the way in providing next-gen refrigeration with Split-Pak A2L™ refrigeration systems.

Featuring R-454A and R-454C refrigerants, these future-proof systems deliver compliance, efficiency, and sustainability backed by rigorous field testing to ensure proven reliability.

At the same time, we remain committed to supporting our customers with legacy R-449A systems.

Visit our dedicated resource page for information about these units.

 

Master-Bilt’s Split-Pak A2L™ split refrigeration units for walk-ins feature a condensing unit paired with a matching evaporator coil. With split, or remote, refrigeration systems, the condensing unit is installed away from the walk-in cooler or freezer—typically outside the building or on the roof—while the evaporator coil is located inside the walk-in.

Split-Pak A2L models should be used when:

  • Larger capacity systems are needed
  • Height above the walk-in is restricted
  • It’s important to move heat outside and reduce the load on the HVAC system
  • Lower noise levels are desired inside the conditioned space
  • Unchilled product needs to be rapidly brought down to the proper storage temperature
  • Frequent walk-in door openings are expected

The Best Warranty in the Industry

18 Month Parts & Labor Standard; Optional Extended Compressor Warranty Available


Optimizes energy savings by removing workspace heat

Eco-friendly refrigerant provides maximum sustainability

Fully customizable with the widest range of options

Featuring eco-friendly refrigerant

Master-Bilt leads the way in adopting low-GWP refrigerants, staying ahead of the curve with emerging regulatory standards. No single refrigerant meets every need. That’s why we continually test and integrate a diverse mix, including A2Ls and CO₂, to deliver versatile, regulation-ready solutions.

 

Master-Bilt’s split refrigeration units for walk-ins are pre-piped and pre-wired for quick and easy installation. Split-Pak A2L systems are equipped with scroll compressors for maximum energy efficiency, increased reliability and quieter operation.
