Ultra Low Temperature Chamber

Home  |  Products  |  Ultra Low Temperature Chamber

Chamber Capacity : 100 liters to 2,000 liters
Temperature Range : – 90° C to 80° C
Accuracy : +/-0.5° C
Gradient Temperature : +/- 1° C.
Temperature Raise /Fall : 1° C to 3° C
Internal Finish : Interior made of vapor tight pre – polished 16 Swg 304 grade stainless Steel with adjustable / removable shelving.
External Finish : Outer material is 16 Swg CRCA /Stainless steel with primed and phosphate epoxy based electrostatic powder coating finishing for a pleasant appearance.
Insulation : It's environmentally friendly free of asbestos and CFC guarantees the best possible insulation values and hence, the lowest possible operating costs.
Work Space Conditioning : Air circulation within the chamber is Laminar airflow provided with suitable capacity of fan motor and impeller for uniform distribution of temperature and to maintain within specified limits. 
Heating System : Fast responding U-shaped jacketed air heaters are used to achieve the desired positive temperature. Air heaters are placed in the conditioning plenum such that there is no direct radiation from the heaters on to the test specimen.
De-Humidification System : A refrigeration based   de-Humidification system provided for avoids the condensation forming on test specimen.
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 cutoff switch and overload protection for the system.  Oil separators with oil return & hot gas defrost system
Door & Gasket : Robust type hinges fitted on the right hand side of the chamber with front opening single door. Leak proof double lined silicon gasket will be provided.
Ports Holes : Even in the standard version of the equipment all sizes are equipped with two standard ports. These are located on the left or on the right side of the test chamber and can be used for inserting measurement and control cables, other supply connections or additional equipment.
Viewing Window : The multi pane window will consist 4 toughened clear glasses sealed with silicone and separated by spacers to form a completely vaccumised window.
Controller System : PID/ PLC based Color display Touch screen TFT provided with program logic controller.  No. of programs & profile segments with ramp & soak duration provided for cyclic operation. The controller is able to communicate with many different types of hardware using high speed RS 232/485 communications ports and Ethernet / USB communications for fast downloads. Remote monitoring and operation. Internet explorer based comm. On board comms ports. Set value & process value with graphical display on main screen. Graphical trend and operating parameters of auto tune & calibration. PC communication facility for operating the chamber through PC & data logging option provided with log interval. The latest version software (user friendly) provided with controls & instruments. Fault indication.
Sensors : The HygroClip series are digital humidity-temperature probes based on the Air Chip 3000 technology or 4 to 20 mA. These probes feature a UART serial interface and two 0…1 V linear analog output signals. The probes are designed for use with the HygroClip 2 generation of ROTRONIC humidity-temperature instruments. The probes maintain all of the benefits of the original HygroClip technology such as the possibility of hot-swapping probes and feature significant improvements in the area of measurement accuracy and functionality.
Safety : Moreover, the test chamber is equipped with an adjustable safety cut – out against high and low temperatures. Low water level cut – off with alarm issued visually as well as acoustically. In addition, a potential – free contact is available. Every electrical functional circuit is equipped its own safety facility which shuts down the functional circuit affected or the entire test chamber in case of a malfunction.
Electrical Connection : 415 V AC +/- 10%, 50 Hz, 3 phase/N/PE Or 230 V AC +/- 10%, 50 Hz.
Test Standards : DIN, MIL, IEC, QM – 333,IS 9000, IS,
