2.2 Description of the TCU 40/80
The TCU 40/80 is a single-channel temperature control unit engineered for temperature control of remote
heat loads.
From distances up to SO feet, the TCU 40/80 can cool the heat load generated by the process equipment.
The coolant circulates through the TCU 40/80, where it is cooled or heated as required, then is transferred
to the process equipment, and returns in a closed loop. The TCU 40/80 maintains supply coolant at a
temperature between -40 °C and +80 °C, selectable in 0.1 °C increments, with a tolerance of ±1.0 °C.
2.3 Lockout procedure
To prevent accidental or unauthorized starting of the TCU 40/80 during maintenance, disconnect the
power cord from the receptacle and install an appropriate lock-out device (Hubbell Small Plugout™ or
equivalent) on the end of the power cord.
