​

Sensor:

​

• Hygroclip type for temperature and humidity ozone sensor, CO2.

Design:

​

• Material of test chamber selected in such way that it will have minimum reaction with ozone.

• The chamber is so designed that hazardous ozone gas is contained internally eliminating the need to provide additional external venting and filtering of the Sent gas.

• The ozone source is generated from fresh air from the environment using air compressor and filters.

• This air has Passed through the container containing UV lamp as required by ASTM.

• The equipment provided with a generator and Controlling of air ozone stream. The generator located outside the chamber.

• UV absorption analyser auto measure and Control concentration of ozone by the principle of measuring absorption of UV light in a sample of gas flowing through Optical bench.

​

De humidification system:

•   A refrigeration based de humidification system provided to avoid the condensation forming on test specimen as well as control the lower relative humidity.

• The desired level of lower humidity will be achieved by maintaining the precise dew point temperature.

• The output will be automatically activated based on the set points as well as in ramp up mode after a low temperature cycle.

Humidity control systems:

• A low pressure free vapour moisture generator using direct vaporisation system  is used for stimulating the required humidity.

• Reservoir with automatic float switch/valve provided to maintain at appropriate level for continuous water supply to the humidity tank .

• The saturated air to be circulated into the workspace.

​

Refrigeration System :

​

• A High boosted low temperature application sealed/ semi sealed compressor is used to

• Achieve and maintain the required  negative temperatures .

• Non CFC eco friendly refrigerants are used with components complying to all international safety and environmental guidelines.

• The system is provided with adequate safety protection against excessive and low pressure and high pressure.

• Pressure gauges provided to indicate suction and head pressure .

• HP/LP cut off switch and overload protection for the system.

• Oil separators with oil return & hot gas defrost provided.

​

Controller  System:

​

• PID/HMI with PLC based color display TFT touch screen with Program Logic Controller.

• No. of programs & profile segments with ramp & soak duration are  provided for cyclic operation .

• The controller is able to communicate with many different types of hardware using high speed RS 232/485 communication ports and Ethernet/USB communications for fast  downloads. Remote monitoring & operation.

• Internet explorer based comm. On board Comms. Ports. Set value & process value with graphical on main screen.
