Ultra Low Cold Chambers

When the Cables / Electrical Equipments are subjected top extreme cold for a considerable duration of time, they may become hardened and stiff. Such hardness and stiffness cause cracking of the insulation or sheath and may lead to failure of cable / equipments.

The extent and type of change that takes place depends upon the severity of exposure of the sample to cold temperatures. This test makes an assessment of change in equipment performance by subjecting them to accelerated ageing in very low temperature.

The instrument is available in two various different models with temperature range for -0 to -86oC.

The instrument consists of

     Cold Chamber Size (as per requirement of customer)

     Digital Temperature Indicating controller

     Glass Window on the door. (if required)

     Very high displacement compressor of about 22 per revolution

     Highly efficient refrigerant R404A having a boiling pt. Of -46DegC

    Our freezer does not require a low ambient temp. It can work even at an ambient of 40DegC

    We use a down feed evaporator so as to improve the refrigeration effect and coeff. Of performance of the system as a whole

    High density PUF of about 60kg/cm3 so as to hold the temperature for a longer time

    Hot discharge is circulated on the mouth of the freezer to prevent cooling losses

    Microprocessor based temperature controller for accurate temperature and longer compressor life.

    Standard compressor of 1 hp

    Cascading Refigration System

    Copper Capillary of higher wall thickness to last longer

    Uniform capillary distribution on the surface of chamber for better / faster and uniform cooling within chamber.

    Double door formation (acrylic + normal) for better insulation

    Noise less operations
