3.2.1 Temperature (& Humidity) Control
The Platinous Sterling Series employs a BTHC system to control temperature and humidity. “BTHC” stands
for Balanced Temperature and Humidity Control.
The BTHC system balances temperature and humidity inside the chamber to reproduce the desired
conditions. This is done by continuously controlling the capacity of a cooler (dehumidifier) of high
, and a heater and humidifying heater* of low heat load, in real time.
Refrigerator capacity is also updated continuously to minimize the heat load from specimens. The central
unit, which controls everything, is the temperature (and humidity) controller. The instrumentation acts as
the user interface.
*Not provided on temperature only chambers.
