Manufacturing Features

3D full-parameter modeling, intelligent and efficient; PC virtual assembly will be performed before manufacturing to ensure perfect functionality without design omissions; motion simulation and stress analysis to ensure design rationality.

The channel modularization —- ensures manufacturing consistency and stable batch performance.

Seam processing — Japan imported high and low temperature resistant sealant and increased stainless steel pressure strip sealing treatment, to ensure long-term use of the equipment as a whole does not deform, the structure does not leak air.

3S manufacturing management process —- is manufactured in the factory according to the fixed scientific process to ensure high efficiency and stable quality; to avoid the customer site production, the process can not guarantee, resulting in unstable performance. Welding and gluing process picture

Expansion Valve

1) Danfoss electronic expansion valve. Refrigerant flow servo control (i.e. cooling not heating, heating not cooling “static balance” technology)

(2) electronic expansion valve as a new type of control components, has broken through the concept of throttling mechanism, it is an important part of the refrigeration system intelligence, but also an important means of refrigeration system optimization can be truly realized and guaranteed.

3) Product features:

1. Totally enclosed design, stepper motor drive

2. From fully closed to fully open in a very short time

3. High accuracy, extremely long life

4. Linear flow change, wide range of cooling capacity

5. Continuous cooling adjustment, no liquid hammer phenomenon in the refrigeration circuit

6. High reliability due to the integration of the motor and the valve, and the ceramic valve plate and valve port parts are resistant to wear and tear.

4) Main advantages

1. To achieve active control of the refrigeration system, rather than the original thermal expansion valve fixed proportional adjustment can not be controlled. Can be adjusted for different modes and operating conditions in advance and optimize the output.

2. Due to the electronic expansion valve dead cycle control back to the front end is the temperature plus pressure dual sensor high response direct control, so that you can provide the best evaporator liquid supply, so that the refrigeration system in a wider range of work are to achieve excellent cooling capacity output.

3. Energy saving: the electronic expansion valve full range of self-adjustment + active adaptation to adjust the cooling capacity output, making the system more energy efficient
