5°C to 95°C — Distilled Water or Deionized Water
(up to 3 MΩ-cm)
Normal tap water leads to calcareous deposits necessitating frequent unit
decalcification, see table on next page.
Calcium tends to deposit itself on the heating element. The heating
capacity is reduced and service life shortened.
-30°C to 80°C — Water with Glycol
Below 5°C water has to be mixed with a glycol. The amount of glycol
added should cover a temperature range 5°C lower than the operating
temperature of the particular application. This will prevent the water/
glycol from gelling (freezing) near the evaporating coil.
Excess glycol deteriorates the temperature accuracy due to its high
viscosity.
-40°C to 200°C — SIL180:
SIL180 is suitable for covering nearly the entire range with just one liquid,
especially when used with the cooling units. See next page for additional
information. Unfortunately SIL180 has a wetting tendency necessitating
the occasional cleaning of the bath cover.
other temperatures:
Cole Palmer offers a range of heat transfer fluids for these temperature
control applications.
SYNTH 60, SYNTH 200, SYNTH 260:
Synthetic thermal liquid with a medium life span (several months) and
little smell annoyance. See next page for additional information.
SIL 100, SIL 180, SIL 200, SIL 300:
Silicone oil with a very long life span (over 1 year) and negligible smell.
See next page for additional information.
Heat transfer fluids are supplied with an EC Safety Data Sheet.
Ensure, when selecting the heat transfer fluid, that no toxic gases
can be generated. Flammable gases can build up over the fluid
during usage.
Ensure the over temperature cut-off point is set lower than the fire
point for the heat transfer fluid selected.
The highest working temperature as defined by the EN 61010 (IEC
1010) must be limited to 25°C below the fire point of the bath fluid.
