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. The TW-2 offers an enhanced control, with additional
diagnostic features and autostart capabilities.
Both the TW-1 and TW-2 models are available in single or
multiple-zone configurations, using direct injection or closed
circuit process heating and cooling. Multiple-zone models can
control up to three temperatures at different locations in the
process. Two- and three-zone models have common cooling
water manifolds and electrical connections.
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:
●
Process temperatures up to 250°F (121°C).
●
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:
●
Process temperatures 180°F (82°C) to 250°F (121°C).
●
Use with contaminated cooling water, or with properly
treated and filtered tower or city water..
Isolated circuit (IC) models
separate the cooling water from
the process fluid, which is held in a reservoir. IC models are
recommended for:
●
Process temperatures up to 180°F (82°C).
●
Use with contaminated cooling water or a process fluid
mixture of water and glycol.

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.
