Cooling Coils
The unit is equipped with a cooling coil located behind the stainless steel
baffle in the bath. The bath can be cooled and temperature stability improved
by circulating cold fluid through the coil. For best results, the fluid should be
at least 5°C below the temperature setpoint. The required fluid flow rate
depends on the type of fluid, the setpoint, and the desired stability.
The plumbing connections for the cooling coil are
3
/
8
inch OD stainless steel
tubes located on the rear of the unit. These connections will accept
3
/
8
inch or
5
/
16
inch ID tubing. Tubing is available from Thermo NESLAB.
Connect the COOLING COIL IN tube to the cold fluid source. Connect the
COOLING COIL OUT tube to the cold fluid return (or drain if tap water is
being used).

Boost Heater
EX-221 and EX-511 units are equipped with a boost heater. The boost
heater is designed to provide additional heat to the unit.
To start the heater press the BOOST HEAT switch, located on the front of
the temperature controller, to the ON position. Even though the switch
automatically returns to the OFF position, the boost heater will start to
function. (You can verify this by observing the fluid temperature rising.) The
boost heater automatically ceases operation when the setpoint is reached.
