Tri Gas Incubator Air Jacket Manufacturers Tri Gas Incubator Suppliers

Thermal Shock Test Chamber


Weiber Air Jacket tri Gas Incubator is specially designed for cell culture application requiring below ambient in vitro oxygen atmospheres. It offers both CO2 and O2 control using nitrogen gas to displace ambient air. An infrared sensor selectively measures CO2 concentration in real-time and a microprocessor controls temperature and CO2 concentration.

The large size TFT LCD display shows parameters such as temperature, CO2, O2 and N2 concentration and RH. Air jacketed incubators circulate air throughout the interior of the incubator to maintain constant temperature. It also offers an option for O2 control, which allows tri-gas control for sustaining hypoxic conditions.

It offers wide range of application in cell biology, microbiology, biological-tissue engineering, pharmaceutical research, IVF, human and veterinary medicine, and dental technology -- applications that demand long-term stability, reliability, homogeneity and reproducibility of results.

  1. Material Of Construction: Castor wheel mounted cabinet is double walled with inner chamber of Stainless steel sheet of grade SS 304. Outer wall is constructed out of heavy gauge PCRC steel sheet duly degreased and pretreated with primers , duly painted with attractive stove enamel or powder coated .
  2. Temperature Range: 5°C to 80°C
  3. Temperature Control: The temperature inside the tri gas incubator is controlled by intelligent programmable temperature controller and indicator. This controller is based on the microcontroller Nano watt technology and its ergonomic design suits for any specific requirement of the incubator.
  4. Accurate InfraredCO2 Control System
    The WEIBER” Carbon Di Oxide Incubator uses a microprocessor based, non-dispersive infrared CO2 sensor. The amount of energy diffused to the detector is an exact logarithmic function of the CO2 concentration in the gas between source and detector. The wavelengths used are absorbed by a filter in the CO2 bandwidth making the measurements insensitive to other components, such as water vapor. Advanced design provides a very stable drift-free output requiring less frequent calibration. The sensor is within the chamber air plenum so very accurate CO2 control is achieved.
  5. Insulation: The gap of 75 mm between the outer and the inner wall is filled with special grade glass wool to prevent thermal losses.
  6. Mineral Glass Wool Insulation: Glass mineral wool is one of the most environmentally friendly, stable and sustainable. It does not propagate flames and toxic smokes. The thick it is, the best thermal resistance it has, thus reducing heat losses in our equipments for better sensitivity and economical operations. And its impact on the environment is minimal.
  7. Air circulation: Triple walled back of unit is fitted with two air circulation fans for maintaining temperature uniformity throughout the chamber
  8. Features of Coaxial Circulation Fan:
    • Vacuum impregnated stator winding with dr. back varnish under red baktol
    • Non-hygroscopic.
    • Best IR value
    • Bright bar (EN - 8 class) shaft.
    • Bush bearing of branded companies.
    • Surge comparison testing in fans and pumps eliminates into turn short circulating of the stator.
    • Pressure die-casted-rotor manufactured with zero error.
    • Boats of high accuracy
  9. Doors:Full view inner glass/Perspex door permits inspection of specimens, without disturbing the chamber temperature. Lock and Key arrangement is provided in the double walled outer door.
  10. Illumination:Features top-mounted or side-mounted LED lights that are appropriately positioned within the chamber to provide uniform illumination throughout the working area.
  11. Front Panel: The front panel is provided with separate indicator lamps for main heating and incoming voltage. Digital Temperature controller cum Indicator and voltmeter.
  12. Shelves: The unit is supplied with three shelves of stainless steel sheet.
  13. Voltage: To work on 220/230V A.C. supply.

    Air-cooled condenser is internally grooved finned copper tubes used for high heat transfer area, which not only reduce power consumption, but also bring down the condensation faster. This unit is designed. & verdigris & reduces the resistance, saves energy consumption and ensure good heat exchange.


    HERMETIC COMPRESSOR Single stage Reciprocating Compressor. Give the High Efficiency compared to sealed compressors, Less Power Consumption , Accessible for repairing, low noise level, Less Vibrations, Wide Voltage Range, Designed for Extremely High Ambient ,Full warranty etc.


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


    (a).Low and High Pressure switch

    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.

    (b).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.

    (c).Liquid Dryer

    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.

    (d).Moisture Indicator of

    The sight glass area in the Moisture Indicator shows at a glance the condition of the refrigerant system. The moisture indicator element changes color and indicate if the system is safely dry, or dangerously wet.

    (e). Solenoid Valve

    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.

    (f). 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.

    (g). Suction Accumulator

    Maximum Efficiency of the relief device (expansion valve) because it is supplied with sub cooled Liquid.

    (h). Liquid Receiver

    As per ASME Section VIII Division I for storage of refrigerant.
