Structural Fetuers

• Observation window can be added based on customer requirement.
• Use of 2-box method shortens the temoerature recovery time of the sample.
• Cylinder controlled steady "up and down movement method" of tst basket.
• High air spee and uniforn sample temperature effectively guarantees the uniforrnity of ternperature 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 unifornity in temperture insude the chamber and the temperature and humidity can become constant at a much faster speed. The angle of guide vane can be sadjusted freely, effectively ensuring the uniformity inside the chamber.

Refrigeration System

• Major parts and accessories from international famous brands.
• Refrigerant R404A and R32 are used in the system with the ozone depletion factor of 0.
• All condensers are installed with filtration device, which Ensurees long-term reliable operation of the unit.
• Intelligent control of refrigeration system optimises power consumption.
• Imported compressor: Tecumsch, Chpeland, Bock or Bitzer, low in noise, stable in operation and powerful in performance.
• Before welding, all pipelines are charged woth 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, 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.
