Walk-ins will be constructed of prefab, precision formed, modular
panels designed for accurate, rapid field assembly and in compliance
with the general construction as described in the Master-Bilt®
Architectural Specifications and General Design Information binder.
Per DOE requirements, panels and doors are designed and
certified for use in walk-in cooler and freezer applications.
Metal Finishes:
Interior and exterior wall and roof finish of walk-in coolers and
freezers is 26 gauge acrylic coated stucco galvanized steel. Floor
interior finish is .080 textured aluminum. Floor panels are designed
to support an evenly distributed load of 700 lbs. per square foot
loading (stationary load).
Entrance Door:
Coolers: 2.77
Freezers: 7.79
Entrance door includes:
Adjustable backing plate for each hinge providing for in-field
adjustment of door hinges
An adjustable double vinyl wiper gasket along bottom
Drip guard over door in outdoor models
Self-Contained Refrigeration System:
Dedicated medium temp outdoor condensing units meet the DOE
requirement of a min. AWEF rating of 7.61 (Btu/W-h).
PRS-2 series refrigeration systems consist of a condensing unit
and evaporator coil fully assembled inside a mill finish aluminum
housing. Each system provided wired, piped, evacuated, optimally
charged and run tested. All models are ready to mount on top of a
Master-Bilt® walk-in cooler or freezer. PRS-2 systems may be specified
for compartments 13'6" long and under.
Some indoor models will be provided with power cord for direct
plug in to receptacle. Additionally, systems will contain a factory
mounted diffuser with trim pieces provided loose for finishing box
opening on inside. The evaporator grille is designed to mount flush
or recessed within a 4" thick ceiling panel.
Systems for medium temperature applications are air defrost. Low
temperature models feature electric defrost.
All units contain R-404A refrigerant and are designed to operate
in ambient temperatures up to 100°F. Systems for outdoor walk-ins
also contain a crankcase heater, drainline heater, head master and
weather hood.
