Ecocentric System :
Chamber runs on the basis of Dewpoint control. Less deviations during short-term door opening & power failure. Less utility area Increased storage area. Low operating cost. Minimum power & water consumption. Reduced deviations. Less breakdowns due to standby refrigeration & humidification system. Due to PLC HMI & controlling through microprocessor based PID Temp. & RH operations the on time of both Temp. & RH system is reduced & efficiency of this system is increased with reduced energy consumption.

Heating / Humidification & Dehumidification :
Imported Encolite heaters up to 3 K.W. Air Heaters are provided for
heating above ambient temperatures.
Humidity is controlled by steam injection method. The boiler tank is
used for steam generation, Electro-magnetic switch is used for
sensing the Water Level. Thus eliminating the humidity interruption.
De-humidification coils are installed below the cooling coils
for lower humidity.
Air Circulation : [Laminar Type]
The 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 w orking chamber. This system gives better than 1 deg c. temp. uniformity in working chamber. Uniform forced air circulate across the shelf via air diffusers on the top wall. Uniform horizontal or vertical airflow shall be provided for maintaining uniform temperature and RH in the room. System for adjustable forced air exchange shall be provided with up to 20 air exchanges per hour of fresh air to the room or its equivalent and an option to shut it down when not required. No direct radiation on the specimen
