The carbonation chamber is provided with best air circulation to give better temperature uniformity this is achieved by using one set of motor & blower in baffle wall Compartment to push treated air in working chamber. This system gives better than 1 deg c. temperature uniformity in working chamber, evaporator, heaters & steam injection system is from back side, behind baffle wall, the air circulation blower is also fitted in this compartment only. This arrangement helps to mix steam and air together and pass well mixed air inside the working chamber. Due to above system the temperature and humidity (R.H.) in complete chamber almost remains equal.

Resolution : 0.1°C, Accuracy : ± 0.2°C, Uniformity : ± 1°C
Humidity Range : 40% to 95% RH,
Resolution : 0.1%, Accuracy : ± 1%, Uniformity : ±3%
Range 0-5% by volume with CO2 NDIR sensors, cylinders & regulators directly operated from PLC (fully programmable).
