The control panel of the autoclave gives 230V,
1Ø or 3Ø 415V (optionally) output to connect external
auto-cooling system. AMAR gives 2 options:
(a)
Solenoid valve (Flameproof / non-FLP) connected at the inlet
of the internal cooling coil with external source of chilled water
supply. This is standard for 50ml & 100ml autoclaves, However
for bigger autoclaves if the cold water line pressure is <2bar
then it is better to opt for external pump & tank water cooling
system. Normal tap water cooling is not effective at higher temperature
due to steam back pressure whereas auto cooling system gives positive
pump pressure.
(b) Pump & Water Cooling Tank: This system is used to control
the overshoot in the autoclave & to cool it rapidly to lower
temperature after the reaction is over. It circulates water
to the internal cooling coil of reactors. It is a very essential
feature for highly exothermic or runaway reactions. Cooling
starts automatically if the rate of heating rises suddenly.
It comes with ½ H.P monoblock/ FLP II & IIB/ IIC
coupled pump, tank, pipeline & flexible hose pipes with
QRC & is mounted on the autoclave trolley itself.
