Product Features

●Observation window can be added based on customer requirement.

●Use of2-box method shortens the temperature recovery time of the sample.

●Cylinder controlled steady “up and down movement method”of test basket.

●High air speed and uniform sample temperature effectively guarantees the uniformity of temperature inside the chamber.

●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 vents are placed 45° in the chamber for uniformity in temperature inside the chamber 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 internationally acclaimed 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 optimizes power consumption.

●Imported compressor: 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.
