Original HITACHI G503DH-80D1(2) G503DH-83D1(2) Air Conditioning Refrigeration Compressor Key Feature for Heat Exchange

This model of compressor is suitable for refrigeration equipment such as air conditioning and refrigeration systems. Its main features include:

1. Applicable refrigerants: The compressor can operate smoothly and reliably in various refrigerant environments, including traditional R22 and new chlorine free refrigerants such as R134a, R404A, R507A, and R407C.

2. Safety design: A safety relief valve is installed between the high and low pressure chambers to ensure that the system can automatically release pressure under high or low pressure conditions, protecting equipment safety. In addition, there is a PTC temperature sensor directly inserted into the exhaust chamber of the cylinder block to monitor temperature changes in real time and ensure stable operation of the compressor.

3. Motor protection: Adopting PTC motor protector from KRIWAN company in Germany, and equipped with a delay circuit, the compressor can only restart after 5 minutes of shutdown, effectively protecting the motor from damage. four Energy efficiency ratio: This compressor can be equipped with an energy regulation device, which can achieve high energy efficiency ratio under both partial and full loads, improving overall energy efficiency performance.

5. Application scope: Compressors are widely used in air conditioning, heat pumps, and industrial, agricultural, and commercial refrigeration systems, suitable for various application scenarios
