- Port Specifications: Original position threaded ports with O-ring seals, direct replacement without modification required.
- Key Functions:
- Liquid Storage: Stabilize the refrigerant circulation volume in the system
- Drying: Absorb moisture to prevent ice blockage and corrosion
- Filtering: Intercept impurities to protect precision components
Product Features
1. Original DENSO Quality: Factory配套 DENSO, Sany Heavy Industry installation standard, mature field verification, long service life and low failure rate.
2. Efficient Drying, Ice Blockage Prevention: High adsorption molecular sieve for deep refrigerant drying, eliminating expansion valve ice blockage and ensuring stable cooling.
3. Precision Filtering, Compressor Protection: Multi-stage filtering structure to intercept metal shavings and impurities, reducing compressor wear.
4. Vibration Resistance and Leak Prevention, Suitable for Construction Sites: Thickened shell + anti-vibration mounting bracket, strict sealing process, no leakage under long-term vibration.
5. Ready-to-Install and Easy Maintenance: Ports and holes are completely consistent with original factory specifications, easy replacement, significantly shortening maintenance time.
Installation and Usage Notes
- New parts are factory-sealed with nitrogen. Do not open before installation to prevent moisture damage and failure.
- Apply refrigerant oil to the seal ring on the port during installation to avoid dry friction and leakage.
- After replacement, vacuum the system and add the standard amount of refrigerant, then check the system pressure and cooling effect.
