This compressor adopts scroll technology, offering energy efficiency that is 12% higher than comparable reciprocating compressors on the market. Under ARI conditions (7.2/54.4°C), it provides a cooling capacity of 26400 W with an input power of only 7500 W, achieving highly efficient and energy-saving operation.
II. Exceptional Reliability Design
Flexible Scroll Technology is the core advantage, allowing the scroll discs to separate radially and axially. Debris or liquid can pass through the scroll without damaging the compressor, providing unparalleled tolerance to liquid slugging and contaminants. Compared to reciprocating compressors, the number of moving components is significantly reduced, and the axial and radial flexible design significantly enhances service life and reliability.
III. Comprehensive Protection Features
The built-in motor cut-off device effectively protects the motor from damage caused by high temperatures and excessive current, ensuring safe operation. The built-in pressure relief valve further improves equipment reliability. An oil sight glass and crankcase heater can be added as per user requirements.
IV. Excellent Operational Performance
The noise level is more than 5 dB lower than that of reciprocating compressors, with a noise rating of only 70 dB. It features a smooth acoustic spectrum and soft sound quality design. With nearly 100% volumetric efficiency, it delivers exceptional heating capacity while ensuring high volumetric efficiency.
V. Simplified System Design
The unique unloaded start design eliminates the need for a start capacitor/relay in single-phase compressors. In most applications, it also eliminates the need for a crankcase heater and suction accumulator, reducing system complexity and cost.
VI. Broad Application Range
Suitable for refrigerants R22 and R407C, it is widely used in air conditioning, industrial refrigeration equipment, chillers, cold storage, and other fields. The series covers a range from 1.5 HP to 30 HP, meeting diverse cooling capacity requirements.

Frequently Asked Questions
What are the maintenance precautions for VR108KS-TFD-522 compressor?
Maintenance of VR108KS-TFD-522 Scroll Compressor: Detailed GuidelinesI. Daily Operational Monitoring
Operating Parameter Inspection: Key parameters such as motor current, bearing temperature (not exceeding 70°C), discharge temperature (not exceeding 160°C for R22 refrigerant), suction/discharge pressure, etc., must be recorded per shift. If any parameters deviate from the normal range, the system should be shut down immediately for troubleshooting.
Sound and Vibration Monitoring: The compressor should produce a steady mechanical sound during operation. If abnormal sounds such as a "clicking" noise (valve plate damage), "screeching" noise (bearing wear), or a "muffled" sound (liquid slugging) are detected, the unit should be stopped immediately for inspection. Vibration amplitude should be controlled within ≤0.1 mm/s.
Temperature and Pressure Inspection: Manually check the temperature of critical areas such as the crankcase, crosshead guide, and suction/discharge valve covers to ensure they are normal. Verify that pressure gauges at all stages, as well as those on the air receiver and cooler, indicate values within the specified range.
II. Periodic MaintenanceLubrication Oil Management:
After the first month of operation, the lubricant oil should be replaced, and subsequently replaced annually.
The oil level must be maintained within the range indicated on the sight glass. Insufficient oil can lead to a series of failures such as seizing, bearing lock-up, and motor burnout.
Use only specialized compressor oil. Mixing lubricants of different brands or types is strictly prohibited.
