These equipments are capable of maintaining Relative Humidity 35% RH to 45% RH & are mainly used in Pharmaceutical Laboratories Capsules, Strip packing, Tablet Section, Packing Rooms, Processing Industries, Printing & Lithography, Photographic Industries, Communication equipment rooms, Computer & data storage various other purposes
Heavy gauge construction of CRCA sheet or AISI Stainless steel, Robust angular structure removable casing panel makes all parts easily accessible for adjustments & service when required
Working of Environment Controller (De-humidifier)
The equipment is based on refrigeration principle. It removes the moisture content of humid air in an enclosed room & condenses the moisture of the humid air into water which continuously drops into tray. No chemicals or dehydrating substances are used Relative humidity can be maintained depending upon the cubic feet volume, the temp & no. of occupants in the room. The walls & ceilings should be vapour proof to minimise infiltration of moisture into the room.
It is fitted with a hermetically sealed compressors to operate on 230 volts +1-5% A. C, Single phase 50Hz, with heat exchanging coil, water condensing coil & fan motor assembly. The unit is mounted on a trolley with a water collection tank at the bottom.
Humidity Range : 35% RH
Accuracy : +/-3% RH
