●Adopt imported components & parts from famous internal brands

●Adopt R404A and R23 refrigerant 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 applies to large range of load and the running power is lower.

●Imported compressor: Copeland, Bock or Bizter, low in noise, stable in operation and powerful in performance.

●Before welding, all pipelines shall be charged with nitrogen to protect the interior of the copper part from oxidation. The weld junction is sprayed with varnish for protection. The company is one of the manufactures up to this standard.

●Refrigeration unit adopts modular production, including sub-assembly, part assembly and general assembly; set up the elbow manual guarantees the uniformity of the system; standardized modules are convenient to install, debug and maintain. 

● Integrated design of air supply channel and refrigeration unit.

● Observation window with electric heating film guarantees clear sight.

● The inner chamber is made by SUS304 stainless steel; the external chamber is made by two-sided galvanized steel sheet and its surface is treated by electrostatic plastic spraying. 

● The refrigerating system, waterway system and electrical control system have been modularized, placed separately and are safe and reliable. 

● Refrigeration system intelligent control, suitable for a wide range of load, less power consumption.

   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, powerful in functions. The touch screen is equipped with visual editing software, PLC logic programme, extensible I&O port and extensible multi-point temperature; USB interface allows users to export data (time optional). Remote monitoring is realized through RS485 communication and PC connection. 

●The controllers are developed independently by our company with high performance. Characterized by 65536 color 7’’, TFT true-color touch screen and 800×480 dot matrix, it ensures realistic effects and comfortable 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; extensible I&O port can be used to prepare different control programs according to requirement to realize different functions; they can be developed separately according to actual environment but can be controlled by computer intensively through software. The controller interface adopts consistent style, convenient for users’ operation.

●With PLC program control, this system has timed running & stop function and power failure protection function as well as better stability.

●It can be connected to a centralized monitoring software and supports communication protocol, convenient for users’ secondary development; multiple test chambers can be monitored remotely. 

●Automatic pure water supply device of temperature-humidity test chamber.

●Communication port and software for remote control and data transmission.

●Air dryer.

●Low-temperature and super low-temperature system (it can run for a long time; super low humidity 5℃/5%RH).

●Lead hole of different specifications(φ50, φ80, φ100, φ160, etc,) are optional. 

●Temperature recorder (record the curve).

●Movable temperature sensor. 

●Customize the sample cart according to users’ needs. 

●Non-standard customized equipment can meet users’ demands. 

●Special load-bearing sample holder and the bottom plate.
