In case of air to air chamber the heated air and cooled air are used

3 Zone: Sample is placed in the test chamber at higher temperature than test temperature, in high-temperature chamber and low-temperature chamber. Rather than only hot and cold temperature the specimen flows between hot, ambient, and cold zones. When converted into high-temperature test, cold chamber and ambient chamber door is closed, hot chamberdoors are opened, and test chamber works. When it comes to low temperaturetest, cold chamber door open, and low-temperature chamber works.

When it comes to ambient chamber temperature test, ambient chamber door open, and ambient-temperature chamber works.

    The compressor is mounted perfectly to ensure recommended level of sound and vibration.

REFRIGERATION CONTROL

  • Low and High Pressure switch of RANCO/Danfoss

    Which ensures the compressor and refrigeration system when low pressure will occurs it trip off the compressor. This is the only operator friendly switch can easily reset.

  • Hand Shut off Valve
    Is the only Condensing Unit, which is equipped with it. This valve is used for pump down the total gas in to the condenser & receiver in the faulty condition.

    Which is equipped in the liquid line for ministration of moisture in the liquid. It will collect all the moisture in side the refrigeration line as well as gas.
  • Moisture Indicator of Danfoss make
    The sight glass area in the Moisture Indicator shows at a glance the condition of the refrigerant system. The moisture indicator element changes colour and indicate if the system is safely dry, or dangerously wet.
  • Solenoid Valve of Castle make
    In most refrigeration applications, in order to automatically control the flow of fluids in a system, it is necessary to be able to start or stop the flow in the refrigerant circuit. An electrically operated solenoid valve is usually used for this purpose. Its basic function is the same as a manually operated shutoff valve, but it can be positioned in remote locations, and may be conveniently controlled by simple electrical switches.
  • Oil Separator of Stainless Steel 304

    The oil separator intercepts the oil mixed with compressed gas and returns it into the crankcase of the compressor, thus assuring an efficient lubrication of its moving parts. Also, it improves the overall efficiency in the system.

  • Mineral Glass Wool Insulation: Glass mineral wool is one of the most environmentally friendly, stable and sustainable insulates available. Glass wool is incombustible by nature. Euro class classification is A. It does not propagate flames and toxic smokes. Thanks to a dense entanglement of materials with a low conduction and trapping a great amount of air, glass wool is an excellent thermal insulant. The thickest it is, the best thermal resistance it has, thus reducing heat losses in our equipment’s for better sensitivity and economical operations. And its impact on the environment in manufacture, use and disposal is minimal.
