All Arctic
hinged personnel doors are foamed-in-place with
CFC-free urethane foam. This manufacturing
technique eliminates any structural wood in the
door and enables Arctic to attach the door to the
frame with (A) heavy duty, self-closing, cam
action, gravity hinges that are bolted to
steel plates with machine screws, ensuring
maximum strength and eliminating sagging. Door sections
are internally pre-wired at the factory for
115-60-1. Field connections are made in the light
fixture base, which serves as a
junction box.
Standard
exterior door hardware includes (B) 36 in.
high aluminum diamond-tread kick plates in
and out, and (C) a heavy duty locking door
latch handle with a keyed cylinder lock.
All walk-in
doors include a factory installed (D) 2 1/2
in. dial thermometer and (E) pilot light
and light switch.
Doors are
equipped with a (F) heavy-duty hydraulic door
closer to ensure a gentle, positive and
complete door seal.
All Arctic walk-in doors and frames are
reinforced with high impact ABS plastic.
This framing provides extra support and
rigidity to prevent warping, racking or
twisting. By reinforcing the doors and frames
with high impact material three additional
benefits are achieved:

• The
ABS Lining: Reinforces the door and frame
to resist the day in and day out impact of carts,
hand trucks, and crates.
• Thermal efficiency: ABS is an
efficient insulator. Use of ABS in the door frame
eliminates the need for heater wires in most
applications creating a thermal break between the
warm metal skin of the walk-in on the outside and
the cold metal skin on the inside. This thermal
energy efficiency also enables Arctic to use very
low wattage which is less costly to operate. The
heater wires on our freezer doors are wired to a
temperature sensing device that prevents
overheating prior to start-up of refrigeration,
during occassional maintenance shut-downs, or in
the event of a compressor failure.
