Stability Chamber, Temperature, Humidity, Heating, Cooling.
Introduction to Stability Chamber
It is constructed in compliance with ICH guideline, 21 CFR part 11.
Stability Chamber is intended for performing different type of test where the temperature and humidity of sample environment must be controlled within certain limits. Our policy of continual liaison with leading researchers ensures we maintain our premier position as suppliers of high quality Stability Chamber and associated facilities. Our Stability Chamber were designed with Safety, Reliability, Ease of operating and ergonomically.
- Test space dimensions are 100 litres to 25000 litres.
- Temperature Range – 20° C to +70° C.
- Temperature deviation +/-0.5° C.
- Temperature Resolution 0.1° C.
- Temperature Gradient +/- 1° C to 2° C.
- Average Temperature Raise/Fall 1° C to 5° C.
- Humidity Range 30% RH to 97% RH.
- Humidity deviation 2% RH to 3% RH.

Interior structure made of non frost vapour / air tight type. 16 Or 18 SWG 304 grade stainless Steel with adjustable / removable shelving. Outer external structure made of 16 Or 18 SWG CRCA /GI/ Stainless steel with electrostatic powder super fine coating finishing for a good appearance.
Insulation is environmentally friendly free of asbestos and CFC free mineral fiber insulation guarantees the best possible insulation values and hence, it will decrease the operating costs.
CFC free Foamed in place Poly Urethane Foam (PUF) pre-fabricated. 80 mm puff panel insulation only for dismantling ITSTW models.
Door hinges fitted on the right hand side of the chamber with front opening single door. Double lined ‘A’ grade silicon gasket on door as well as chamber body so that like proof tightens the door for better performance with multi pan glass viewing window. Defogger heaters provided with an auto cut – off as well as suitable illumination provided to view the specimen under test.
In ITSTW models flush mounted type door. Glass window for viewing inside. Positive cam lifts hardware. Safety release exit device for opening door from both the sides, only for dismantling ITSTW models.
Air circulation within the chamber with suitable capacity of fan motor and impeller for uniform distribution of temperature and humidity to maintain within desired limits. Only the impeller will be exposed in the conditioning plenum with drive motor from outside of the chamber. Condition plenum covered with a detachable type sheet for friendly maintenance of the chamber. Noise level is < 70db.
Quick responding jacket type air heaters are used for heating system to achieve the set value temperature. Highly uniform temperature distribution minimises variations in test results over multiple specimens. Air heaters are placed in such manner that, there is no direct heat radiation from the heaters on to the test specimen.
Direct vaporisation humidification system with low pressure steam vapour is used for stimulating the required humidity. Reservoir with automatic float switch for maintain at appropriate level for continuous water supply to the humidity tank.
A refrigeration based de-Humidification system provided for avoid the condensation forming on test specimen as well as control the lower relative humidity.
Water Cooled / Air-cooled mechanical type single stage non CFC refrigeration system. Ozone friendly refrigerant with hermetically sealed / low power consumption high boosted semi sealed compressor provided and system is designed such a way that, safety protection against high / low pressure and temperature. Electronic auto expansion valve system for expansion mechanism. Water / Air cooled condenser. Plate fin type cooler. Refrigerant R404A. Pressure measuring device provided for measuring suction and head / discharge pressure of refrigeration systems. HP / LP cutoff / Oil separators with oil return system.
Programmable controller using large screen display. Instrumentation package features flexible. Other functions are included user friendly operation with TFT LCD touch screen as well as key input, graphical display of program patterns, testing history trend grapes. A 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, networking and USB communications for fast downloads. Power failure recovery operation system.
Microprocessor PID non programable controller for Temperature as well as Humidity in RE models.
P.T 100 sensor is measuring the temperature and high precision RH sensor for humidity measuring. The measuring method considerably improved by using of an continuously wetted humidity sensor and this type wetting effects the self cleaning procedure of the sensor and vastly improving the service life.
Stability Chamber equipped with an emergency stop switch. Control circuit over current protection. Thermal fuse. Adjustable adequate safety cut – out against high and low temperatures. Chamber door limit switch. 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.
Cable Port holes are located on the left or on the right side of the test chamber and shall be used for inserting measurement and control cables, other supply connections or additional equipment with rubber plug.
Standard specification shelves and shelf are added as required.
Drain out let pipe with suitable fittings.
Electrical connection 415 / 220 V AC +/- 10%, 3 / 1 phase/N/PE 50 Hz.
