CONTROL
Heat Boosters supply economical drying heat to individual
drying hoppers for the most efficient material pre-conditioning system available. With a temperature range up to 350°F
{178°C}, and a full complement of safety devices, Heat
Boosters are exceptional for providing safe, precise temperatures for drying.
Each Hopper Temperature Controller
is equipped with a Heater Box (left)
that connects directly to the drying hopper and a precision DC temperature
controller (right).
FAST RESPONDING, ENERGY EFFICIENT HEATERS
The HTC Heat Boosters feature tube
type heaters with fast responding, energy efficient, open-wire resistance
heaters located within mica-lined
stainless steel tubes. High temperature
safety shut off protection is an integral
feature of each HTC.
The HTC controls feature a lockable
fused disconnect switch, solid state
heater contactor, isolation contactor for
over temperature safety protection and
a proportioning temperature controller.
The temperature is monitored and
controlled with a remote sensor located at the hopper air inlet.

Allows you to heat hoppers individually for your unique drying needs.
n
Precision heat control
Features dual display of setpoint and actual temperatures.
n
Safe surface temperature
Insulated heater box ensures safe surface temperature.
n
Safe operation
Redundant safety switches and alarms help eliminate accidents.
Accurate, safe temperature control
Drying temperatures are set and monitored easily with the DC Control which
displays both setpoint and actual temperatures. Over/under temperature and
temperature deviation faults are also clearly alerted along with low airflow conditions, which prevent operation during hopper cleaning or without airflow from
the central dryer.
