Environmental temperature humidity control test room
Temperature humidity control test room is used to test and store a wide range of products in specific temperature and/or humidity conditions. Applications include, but are not limited to, shelf life testing, stability testing, expiration date testing, accelerated aging and other testing for pharmaceutical, packaging, life science, personal care, medical, bio-medical storage, research, and more.
Features
1. The content can be enlarged or narrowed according to user's environmental requirement.
2. Combined board, convenient to assemble and disassemble, simple structure.
3. Use pollution-free freezing medium R404, R23.
4. Capacious and brightly observation window with high light indoor explosion-proof, whitch allowed users to observe all indoor at any time.
5. Omni-directional safety protection device and power-off memory, ensure the safety of machine itself and users.
6. Winds blow out of the ceiling, whitch can reduce the influence of the wind indoor to the sample, and can also meet the demand of low wind speed and high degree of uniformity. The machine can contact to the computer, recorder(optional).
Humidity System
Humidity is by steam injection. Humidity system consist of boiler tank, which is fitted with two nos. Of boiler heaters, one heater works as a stand by and automatic switch over to stand by heater if regular fails and give alarm. A water reservoir tank is connected to the boiler tank. DM water is preferred. A magnetic float switch provided for safety for boiler low level to cut off the its supply.
Cooling System
CFC free, the cooling system consists of hermetically sealed compressor coupled with evaporation coil and condenser, safe guarded by time delay circuit. Refrigerant 134A.
