QS Series Walk-In Coolers & Freezers

Master-Bilt walk-in coolers and freezers - QS Series with self-contained refrigeration systems.

QS Series walk-in coolers and freezers feature panels matched exclusively with one-piece Capsule Pak™ or Capsule Pak ECO™* refrigeration systems for an easily installed solution.

The refrigeration systems also feature a flush-mounted evaporator coil in the ceiling that doesn’t hang down and allows 100% usable interior space.

Capsule Pak ECO™ refrigeration systems contain R290 refrigerant, providing many additional benefits, including a significantly reduced Global Warming Potential of 3.

QS Series walk-in coolers and freezers feature fast and easy installation with cord and plug electrical connection. Additionally, indoor models don’t require a drain line.

These single-compartment coolers and freezers are available in sizes up to 14′ in length and in heights of 6’7″ & 7’7″ with floor and 7’4″ floorless.

Standard features include a deadbolt locking handle for security, and high output LED light positioned above the door to prevent interference with shelving or product.


*Capsule Pak ECO models offered on indoor walk-ins only.
