Walk in Radon Calibration Chamber
Walk in Radon Calibration Chamber
Model : SRL / WIRCC-12
Application :
Used for large number of sample in hospitals, Research institution. Public health laboratories etc. These chamber can be used for environment testing of production sample & large size equipments where temp. & humidity are to be controlled. They are suitable for storage of electronic components, biological specimen & accelerated ageing test of large number of pharmaceutical samples. They can also used for botany, cytological, Deptsrturents, plan & animal breeding laboratories where controlled condition of temp. humidity & illumination are required.
Construction :
MOC of the Chamber will be: Double walled Chamber with Inner of stainless steel 304 grade & outer of stainless steel 304 grade. PUF Insulation in between two walls.
Door : Large viewing windows which shall be vacuum sealed. The chamber shall be leak proof. A smoke test shall be performed to determine any leakage. A fancy door to be provided to make the chamber aesthetically appealing. Flush type doors of metal surfaces (as per above specification of metal) with proper puff insulation of above mentioned standard. Doors shall have magnetic snap-in perimeter gasket. self-closing cam lift gravity hinges or its equivalent, a posi-seal door closure or its equivalent. Door shall have key lockable latch handle. Doorjambs shall be made fiberglass reinforced plastic or any other suitable material compatible with constructed door.
Air Circulation :
The Walk in Radon 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.
Temp. & Humidity Range :
+5°C to +50°C
Accuracy : ±0.2°C, Uniformity : + 2°C, Resolution : 0.1°C.
Relative humidity from 30% to 95%
Accuracy : ± 2% RH , Uniformity : + 5% RH., Resolution : 0.1% RH
Controller : [PLC with HMI TFT screen]
Display of set value and process value. Provision for introducing additional power supply and signal, communication cables for the instrument. Data logging software to store data on a desktop or laptop. USB, RS 485 RS 232 cables on external body. Provision for auto switch ON and OFF of the pumps supplying radon gas to the chamber to maintain the desired concentration values.
PLC Control system with touch screen display & HMI for data Storage, data logger reading & audit trail, Door access & SMS records, Email alert. Data Logger 8 temp + 8 RH. Data Logger with LCD display window capable to store nonvolatile data memory up to 5000 readings with audit trail facility complies 21 CFR Part 11. Change over to stand by system automatically as per schedule or on detecting fault with current system Temperature & Humidity overshoot and under shoot protection Mobile Alarm system, Door Access, system setting reset , Graph, SMS, Email alert, etc. In built PC port for connectivity for PC base operation of data management. Protection of ups system in built with the controller for safe and uninterrupted functioning.
Trays & Racks :
Removable SS perforated trays are provided, adjustable and will slide out for easy clean up. Assembled Stainless Steel racks to accommodate trays.
Humidification & Dehumidification :
Will consist of humidifier tank fitted with boiler heaters, and give alarm if fault occurs or Ultrasonic Humidification System. Water reservoir tank will be connected to the humidifier. De humidification coils are installed below the cooling coils for lower humidity
