- Rotameter for Refrigerant flow measurement.
- Duct : Air duct of size 250 x 250 make out of
CRC sheet in which evaporator is fitted.
- Baby Boiler : Electrically fired small baby boiler for
maintaining humidity of air with electrical heater
- Blower : 1 HP capacity centrifugal blower with air
control arrangement.
CONTROL PANEL :
- 12 Channel Digital Temperature Indicator
