The following working fluids are usually used in the temperature bath:
-10°C to +90°C Water (de-ionized) - Glycol Mixture
-20°C to +250°C Silicone Bath Oil
Suitable bath fluids can be ordered from BROOKFIELD.
We recommend strongly that the upper temperature limit be set at
the liquid circulating thermostat to +95°C if water is used and to
+250°C if oil is used.
III.3.2 The Peltier Temperature Control Device
If the R/S CPS+ has been equipped with a Peltier temperature control system (i.e. model
R/S CPS+ P1 or R/S CPS+ P2), a bath/circulator is not used.
The Peltier temperature sensor Pt100 allows temperature regulation from 0°C to +135°C
(Model P1) or from +20°C to +180°C (Model P2).
A switching power supply (15V/60W) in the Peltier Unit P-TS supplies the Peltier ampli-
fier with power. A green light indicates that power is on while a red light indicates a fault.
For very low temperature operation with the P1 (under 10°C)
tap water circulating through the Peltier plate will improve
temperature control.
The Peltier Supporting Unit P-TS shows all existing control elements, indicators and con-
nections in Figures 4-A and 4-B.
