The shield is made of stainless steel. Has good corrosion resistance, high temperature and dusty corrosive gas in the environment more use, to adapt to the ambient temperature of -40 ℃ to +120 ℃. In the system to install a small air-conditioning semiconductor refrigeration system, through the semiconductor N.P energy conversion, to achieve the purpose of cooling. When the temperature sensor within the protective cover in the temperature over-temperature signal issued by the over-temperature, the electronic cooler began to cool; when the temperature dropped to a safe value of the electronic cooler to stop working. This intelligent cooling device can be issued to reduce power consumption, more to extend the service life of the device, and makes the protective cover easy to seal. Widely used in steel, cement, building materials, chemical plants and other industries, improve production efficiency, improve the working environment, reduce labor intensity.

Use in the field does not have the compressed air and cooling water cut high temperature operating area.

Features:
1. Simple structure, no mechanical movement, no wear, reliable operation, easy maintenance.
2. Cooling speed, the cooling rate can be adjusted by adjusting the operating current.
3. Small size, light weight, can greatly save the area.
4. Do not use refrigerant, cooling effect, do not pollute the environment.

Environmental requirements:
Ambient temperature -50 ~ +200 ℃ Relative humidity ≤ 80% (40 ℃
Atmospheric pressure 86 ~ 106Kpa dust concentration ≤ 200mg / m3 (subject to cement dust)
 
Another can be customized according to user needs.
