The Thermolator TW models circulate water at a temperature
higher than the available water supply, to add or remove heat
as needed to maintain a uniform temperature setpoint in the
process.
Conair TW Thermolators are available in single or dual-zone
configurations, using resistance heating and direct injection or
closed circuit cooling. Dual-zone models can control at two
different temperatures at different locations in the process.
Two-zone models have common cooling water manifolds and
electrical connections.
WHAT IS THE
THERMOLATOR?
Thermolator TW Series UGH025-0504
2-2 DESCRIPTION
TYPICAL
APPLICATIONS
IMPORTANT: Do not use
deionized water or glycol
mixtures containing additives
in a Thermolator. Softened
water or glycol mixtures with
additives, such as automo-
tive fluids, can damage the
Thermolator. Glycol/water
process loop mixtures should
use industrial-grade ethylene
glycol only.
The best model for your application depends on the process
temperature you need to maintain and the quality of the cool-
ing water supply.
Direct injection (DI) models control the temperature by
discharging heated process water and adding cooling water
directly from the water supply. DI models are designed for:
l Process temperatures up to 250°F (121°C).
l Use with chiller water or properly treated and filtered
tower or city water.
Closed circuit (CC) models add cooling water to the process
loop only during the initial filling or when make-up water is
needed. CC models are recommended for:
l Process temperatures up to 250°F (121°C).
l Use with contaminated cooling water.
Isolated circuit (IC) models separate the cooling water from
the process fluid, which is held in a reservoir. IC models are
recommended for:
l Process temperatures up to 180°F (82°C).
l Use with contaminated cooling water.
l When process and cooling fluids are different.
