4.4 Recommended liquids
The following table lists the recommended liquids for different temperature ranges.
Always ensure the liquid used is safe and suitable for your working temperature. If using
non-recommended heat transfer liquids, it is the responsibility of the user to conduct an
assessment to ensure the intended fluid is compatible with the T100IN and vessel. If
using non-recommended heat transfer liquids it is important to set the over-temperature
cut-out to a value no higher than 25°C below the fire point of the liquid. If in doubt please
contact the Grant technical support team.
Temp range Recommended liquid Comments
-30°C to 30°C
50% water, 50%
antifreeze (inhibited
ethylene glycol) WARNING: Ethylene glycol is toxic – follow the
manufacturer’s instructions.
For safe disposal consult your local
regulations.
Use a lid to reduce the dilution of the mixture
caused by condensing water vapour from the
air, and to maintain the cool down rate.
0°C to 30°C
80% water, 20%
antifreeze (inhibited
ethylene glycol)
5°C to 99.9°C
Water* Water can be used but care should be taken
above 60°C as hot vapour can be dangerous.
Use a lid or polypropylene spheres above
60°C to ensure good performance & reduce
evaporation.
At temperatures approaching 99°C the
temperature performance will be affected due
to localised boiling.
The units should not be used to boil water.
70°C to 120°C
Silicone fluid
Viscosity ~20cs
Flash point ≥230°C
Fire Point ≥280°C Dow Corning DC200/20 silicone fluid is a
suitable liquid
– follow the manufacturer’s
instructions.
For safe disposal consult your local
regulations.

4.5
Installation
Place the Inspissator on a level, non-combustible surface. Ensure that the
mains plug and the switch at the rear of the unit are easily accessible.
If the equipment has been transported or stored in cold or humid conditions,
condensation may form inside it. If that could have happened, allow time (at
least 2 hours at room temperature) for the condensation to evaporate before
using the equipment.
Do not block or restrict ventilation slots.
4.6
Electrical supply
Check that the supply voltage marked on the serial number label, and the type
of mains plug, are correct for your mains supply outlet, which must have a
ground connector.
The T100IN must only be connected to the mains using the mains cord supplied
or one with an identical rating (see section 9.4)
