Programmable Temperature and Humidity Chamber With Double Test Space Vertical

Energy regulation measures are adopted to adjust the refrigeration capacity of the system according to different cooling speeds and temperature ranges while ensuring the main technical indicators of the test chamber, energy regulation measures are added, such as evaporation temperature regulation, energy regulation, and hot gas bypass energy regulation to ensure that the energy consumption of the equipment is reduced while meeting the main technical indicators,
Advanced PID regulation technology is used to greatly reduce the energy consumption of the machine. According to the strict water-electricity separation design method, the safety of the machine operation is effectively guaranteed,
Imported core components and excellent technology ensure the long-term working stability of the compressor,
The equipment has the function of recycling circulating water and switching to external drainage, which can be freely selected according to the customer's water quality conditions.
