Climatest Symor® adopts molecular sieve to dry air, the whole system is controlled by microcomputer, when humidity is high, It will start to absorb moisture,when the humidity reach the pre-set value, it will stop absorbing, and then discharge the water to outside the cabinet by heating,again and again by automatic control. The most effective and environment-friendly moisture-absorbing desiccant is molecular sieve, molecular sieve is the microporous crystal material synthesized by silicon and aluminium oxide. In order to keep the crystal net discharge to be zero, atoms with cations are located in the crystal structure.and the cation used in these synthetic crystals is usually sodium. At present, there are two kinds of molecular sieves widely used in the dry box industry: Class A and Class X. Molecular sieves are synthesized, shaped and activated under strictly controlled production processes. The whole controlled sythesis process can ensure consistency of the three-dimensional pore size. 3A molecular sieve pore size is 3 angstroms, 4A molecular sieve pore size is 4 angstroms; 13X molecular sieve pore size is 8.5 angstroms. The working principle of molecular sieve: Molecular sieves adsorb molecules onto the crystal surface by physical attraction force. Since 95% surface area of the molecular sieve is within aperture,it needs to screen the adjacent molecules by different size. Only small size molecules can enter into the inner adsorption surface of the molecular sieve through the crystal aperture. This selective adsorption phenomenon is called molecular sieve effect. The molecular sieve adsorption capacity and charge density (polarity) are further related to the adsorbed molecules. The molecular sieves can further distinguish which of the mixed molecules can be adsorbed and determine to what extent the charge density can allow the molecules to be adsorbed onto the crystal. Water molecules are particularly small (2.6 angstroms), that belong to highly polar molecules (very strong positive and negative electron density), and are easily adsorbed by molecular sieves, even under very low moisture condition,once the water molecules are adsorbed,they will be firmly fixed on the crystal. The environment-friendly moisture absorption device is equipped with molecular sieve. When it’s absorbing, the memory alloy controller is in tensile state, and the spring is in contractive state,which just make the valve contact the outer baffle, this insulates the outside air from inside dry box air to achieve dehumidification purpose; and after molecular sieve absorbed moisture inside dry box and become saturated, the program will automatically control the memory alloy device to shrink it so that the valve reaches the inner baffle position. Meanwhile, due to the shrinkage of the memory alloy, the spring is stretched and the valve is pulled out of the outer baffle,so that the moisture in molecular sieve will be discharged into the outside. after the dehumidifying process finished, the program automatically control and reset the memory alloy and spring,to restart absorbing status.

Temperature and humidity test chamber has brought a lot of help to many industrial enterprises, but while it brings convenience to us, we should also take good care of them, otherwise they may be brought into the end-of-life phase ahead of time. The way of maintenance is also very simple. After daily use, the equipment is cleaned regularly, but the cleaning of the test chamber is also very skillful. If the operation is wrong, it may also lead to equipment failure. Let‘s learn how to extend the service life of the temperature and humidity test box together. 1, Pls clean the working room with water after each use, then dry the interior with dry cotton cloth. 2, Pls regularly remove dust from the evaporator inside the equipment, and periodically wipe the equipment to ensure clean and tidy. 3, When doing the test, the sample should be uniformly placed onto sample shelves,and the vent should not be blocked to prevent the influence of the test 4, It is necessary to pay attention to the cleaning of water tanks in peacetime, after the test or when the equipment is not intended to be used for a long time, all the water in the tank should be discharged, otherwise it will lead to the formation of scale inside the tank. The water used in the temperature and humidity test chamber must be pure or distilled water, or long-term use may result in a humidifier or internal pipe clogging. Above are the usual use notice of temperature and humidity test chamber, if customer adhere to the above several points,it is really able to prolong the service life of the equipment.
