Specifications

Features

1. Material quality of inner box is SUS304 # mirror-face stainless steel imported, and outer box is steel plate and the paint. Box body is processed shape using CNC machine tool, its shape is beautiful and fine.
2. Heat preservation material used glass fiber cotton of high-intensity PU foam and high density, which can avoid unnecessary energy loss.
3. Large glass window design, viewing angle in all directions, hollow electric plating film and anti-condensation design, built-in lights to facilitate the test sample state of real-time observation in the course of testing.
4. Large-size LCD display screen, simple operation, easy to edit programs. PID with automatic calculation function, show failure message .
5. An RS-232 communication interface, matching recorder, strong expandability.
6. With timing contact, and be able to cope with dynamic testing and measure test.
7. The system-wide multi-security protection and power-cut memory.
8. Freezer imported by the French original armored warrior compressor and use environmental-friendly refrigerant (R134a, R404a, R23).

Refrigeration system

• The original French Taikang industrial low-temperature compressor, characterized by large cooling capacity, low noise, low energy consumption, high efficiency, long-term stable operation.
• Cooling method using air-cooled refrigeration, a full range of imported environmentally friendly refrigerant R404A.
• The use of imported dry filter, imported solenoid valves and other refrigeration accessories.
• Condenser with air-cooled, with cooling motor device.
• Refrigeration evaporator: the use of finned evaporator, which is higher than the average evaporator heat transfer efficiency of 30%, with beautiful, compact, fast heat transfer and other advantages.
• Refrigeration process:
• The use of high-quality oxygen-free copper tube, nitrogen welding, high pressure and anti-leakage process to ensure the quality of welding;
• Pipeline length, inclination, slope and direction are strictly calculated to achieve the best cooling effect;
• Thread welding using high-quality silver electrode, the whole system piping are nitrogen pressure 48H leak detection test, put an end to the possibility of leakage of the system refrigerant.
