11.3 POWERBLANKET warming equipment
The kit tanks can also be kept warm by using blankets from “Power
Blanket”. These blankets are better at maintaining the heat in a more
evenly distributed fashion than the “heat bands”. These could be used
to warm up slightly cold product with intermittent rocking or agitation.
Colder tanks < 50°F should be warmed up only by transferring to a
warm area 75°F90°F (24°C32°C) for a period of time with intermit-
tent rocking or agitation. Power Blanket products can be bought
by contacting Power Blanket Customer service 801.506.0198

11.4 Glas-Col Power Control Description and Operation
The Glas-Col Minitrol is a manually adjusted power control of
percentage timer designed for use with the Power Blanket. Minitrol is
designed to proportion full output power 5.5% to 100% of time
depending on the dial setting. The “Off ” position positively breaks
both sides of the line .
The control can be used on any non-inductive fused resistance load up
to 15 amps and 120 volts. Smaller fuses may be used for protection of
very small loads. Simply plug device into a 3-wire outlet of the control
and insert plug of Minitrol cord into a wall receptacle. The pilot light is
connected across the output side of the control and indicates power to
the load.
Minitrol’s operation and control is adjusted by the operator and does
not utilize a sensing element. After a desired temperature has been
determined on the initial run, a simple resetting of the dial offers
control for repeat operations. This control effectively regulates heating
mantles, tapes and cords. Minitrol may also be used for small furnaces
or ovens, hot plates, dies or other applications requiring infinite control.
The control should not be exposed to ambient temperatures above
125°F (52°C).
In addition to Minitrol, stock is maintained on variable transformers and
automated controls. Write to the address below for more information:
