The design of the heater pad assembly offers the advantage of being field replaceable
without affecting the adjoining heater pads. Separate pads also minimize heat conductivity to
the Perfect•Temp cart body, reducing electrical loads and improving efficiency.
Heater Pad Control (On-Off)
Depending upon the cart model, each Perfect•Temp cart will have 16, 20 or 24 tray
levels. Each tray level consists of two heater pads. Each level is controlled by one or two
selector switches.
On the outside of the Perfect•Temp cart, along the vertical extrusion closest to the
handles, are the selector switches. The toggle switches have three positions: all pads hot, all
pads cold, or side dish pads hot. An optional two-position , two switch per server is
available. This allows individual control of each heater pad.
Cart Lexan Door Option
An optional set of Lexan doors is available for the Perfect•Temp rethermalization cart.
The purpose of these doors is to enclose the tray areas of the cart to reduce or eliminate the
need to over-wrap exposed plated foods. The doors also restrict incidental contact from
unauthorized personnel or patients, reducing pilferage of food products from the patient
trays.
Each Lexan door is secured along one vertical edge by an aluminum extrusion which
provides rigidity and acts as the hinge. The remaining three edges of the door are chamfered
to provide a smooth appearance and eliminate sharp edges.
When closed, the doors are held in place by the switch shield extrusion that encloses
the switches, as well as the edge of the door. To rotate the switch shield, lift the plunger pin
which is secured to the top plate of the cart.
When fully open, the two doors are nested, one in front of the other, against the front
wall of the cart opposite the handle. Once again, release the plunger pin to nest or de-nest the
doors.
