Chamber Light :

chambers provide lights as per option 2 mentioned in ICH guidelines A cool white florescent light for 1,2 million LUX hours exposure. UV-A lights for 200 watt hours / square meter exposure. Both the lights have independent control to avoid over exposure. Chamber is illuminated using 4nos of flourescent tube light to produce visible light (measure in lux). A one no. Near UV light of wavelength 365nm ( measured in watt/sq. Meter) are fitted on topside of the chamber.

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 working chamber. This system gives better than 1 °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.
Optional : To be provided with air flow regulator adjustable 0.2 m/s operated from PLC & HMI.
