Key Features
Product features: large observation window; integrated refrigeration unit, ducts and other accessories; sample power-control terminals; a choice of assembled or fully welded construction; suitability for large test components; independently developed controller. Structural features: the air-supply duct and refrigeration unit are integrated. A ramp is provided for moving heavy objects into the test chamber. The large observation window facilitates viewing test samples inside the chamber. Cable ports on both sides allow measuring instruments and leads to be positioned on either side. The inner chamber is made of SUS304 stainless steel, and the outer enclosure is made of double-sided galvanized steel sheet with an electrostatic powder-coated surface. The refrigeration, water-circuit and electrical-control systems are modular and separately arranged for safety and reliability. Air is supplied obliquely downward at 45 degrees to distribute temperature rapidly and evenly and establish constant temperature and humidity more quickly. The air-guide vane angle is freely adjustable to maintain uniformity. Refrigeration system: imported components from internationally recognized brands are used. R404A and R23 refrigerants have zero ozone-depletion potential. Filters are installed on all condensers to support reliable long-term operation. Intelligent refrigeration control accommodates a wide load range with lower operating power consumption. Imported Copeland, Bock or Bitzer compressors provide quieter, more stable operation and stronger performance. Nitrogen is passed through all piping before welding to prevent oxidation inside the copper tubes, and the weld surfaces are protected with varnish. The manufacturer states that it is among those meeting this standard. The refrigeration unit uses modular production divided into component preparation, subassembly and final assembly. A tube-bending manual ensures system consistency, and standardized modules facilitate installation, commissioning and maintenance. Control system: the Situoma touchscreen temperature and humidity controller was developed for the environmental-equipment industry. It comprises a touchscreen, PLC, temperature module and humidity module. It includes visual editing software, PLC logic programming, expandable inputs and outputs, and expandable multipoint temperature measurement. A USB interface supports data export with selectable times, while RS485 communication connects to a PC for remote monitoring. The independently developed high-performance controller uses a 65536-color 7" TFT true-color touchscreen with a 1024×480 dot matrix for realistic display and comfortable operation. The interface is simple and clear, easy to use and reliable. The controller provides fault detection and protection, alarms and instructions for clearing faults. Expandable inputs and outputs allow different control programs to be written for different functions. Controllers are developed for different environmental equipment, support centralized computer control through common software and share a consistent interface. PLC program control provides timed operation, timed stop and power-failure protection with good stability. Central monitoring software and a communication protocol are provided for secondary development, enabling remote monitoring of multiple test chambers.
