Standard features
●Drawer-type water tank.
●Unique door lock design is convenient to operate and better in sealing performance.
●Large size observation window makes it convenient for operator to observe the test sample inside the chamber.
●Lead holes are available on the two sides of the equipment, convenient for placing the testing apparatus, leads, etc.
●The inner chamber is made by SS304 stainless steel; the external chamber is made by CRCS with electrostatic powder coating.
●Modularized Refrigerator system, waterway system and the electrical control system for safety and ease of maintenance.
●Air is supplied into the chamber from below at the angle of 45. In this way, the internal temperature is distributed evenly, and the temperature and humidity can become constant at a much faster speed. The angle of guide vane can be adjusted freely, effectively ensuring the uniformity inside the chamber.
Refrigeration System
● Major parts and accessories from international famous brands.
● Refrigerant R404A and R23 are used in the system with the ozone depletion factor of 0.
● All condensers are installed with filtration device, which ensures long-term reliable operation of the unit
● Intelligent control of refrigeration system optimises power consumption.
● Imported compressor: Tecumsch, Copeland, Bock or Bitzer, low in noise, stable in operation and powerful in performance.
●Before welding, all pipelines are charged with nitrogen to protect the interior of the copper part from oxidation.The weld joints are sprayed with varnish for protection.
● Refrigeration unit adopts modular production, including sub-assembly, part assembly and general assembly; standardized modules are convenient to install, debug and maintain.
Control System
●Topect touch-type temperature and humidity controller is specially developed by Topect for the industry of environmental equipment; it consists of touch screen, PLC, temperature module and humidity module. The touch screen is equipped with visual editing software, PLC logic programmer, extendable I&O port and extendable multi-point temperature; USB interface allows users to export monthly/weekly data. Remote monitoring is realized through RS485 communication and PC connection.
●The high-performance controllers are developed independently by TOPECT, characterized by 65536 color 7″， TFT true-color touch screen and 800×480 dot matrix, it ensures real effects and easy in operation. In addition, the entire interface is concise and clear, convenient and reliable
●Our controllers have powerful debugging protection function, fault alarm and troubleshooting description; extendable I&O port can be used to input different control programs according to requirement to realize different functions; they can be customized as per requirement.
●With PLC program control, this system has timed running & stop function and power failure protection function to improve stability of the system.
●It can be connected to a centralized monitoring software and supports communication protocol, it is convenient for users to develop the program once again; multiple test chambers can be monitored remotely.
