SUN Q-Tech IV Dual Gas Fully Automatic Aircon Service Unit

Engineered for progressive automotive, truck, and agricultural workshops that need to service both R134a and HFO1234yf refrigerant systems from a single machine, the SUN Q-Tech IV Dual Gas Fully Automatic Aircon Service Unit eliminates the need for two separate aircon service units — delivering complete refrigerant recovery, recycling, vacuum, and recharging for both gas types in a single automated cycle, with built-in leak checking, hybrid vehicle support, and Wi-Fi connectivity.

Key Features:

• Dual gas capability — R134a and HFO1234yf in a single machine allows workshops to service the full range of current passenger car, light commercial, truck, and agricultural vehicle aircon systems without investing in two separate units.
• Fully automatic operation with automatic air purge manages the entire recovery, recycling, vacuum, and recharge cycle for both refrigerant types without manual intervention, reducing operator errors and maximising workshop throughput.
• 2 heated cylinders — one dedicated to each refrigerant type — ensure consistent refrigerant density during the recharge phase, improving charging accuracy and preventing cross-contamination between R134a and HFO1234yf systems.
• 100 l/min vacuum pump capacity at 0.1 mbar achieves deep vacuum quickly and efficiently, ensuring thorough moisture removal from the system before recharging on both refrigerant types.
• 300g/min recovery speed with 2 x 12-litre refillable refrigerant cylinders minimises vehicle downtime during the recovery phase, keeping workshop throughput high across both gas types.
• 2 oil + 2 dye refillable hermetic containers with automatic dye injection allow PAG oil and UV dye to be introduced precisely during the service cycle for each refrigerant type, supporting leak detection and system lubrication without manual intervention.
• Hybrid vehicle function enables safe aircon servicing on hybrid and electric vehicles, extending the unit's capability to the full spectrum of modern vehicle technology.
• Oil change procedure flushes old compressor oil from the system and replaces it with the correct quantity of fresh oil automatically, ensuring accurate oil management on every service regardless of refrigerant type.
• Vacuum leak check and pressure leak check (nitrogen) verify system integrity before and after recharging, identifying leaks that would cause premature refrigerant loss and repeat customer complaints.
• Vehicle database covering car, truck, and agricultural vehicles provides OEM refrigerant charge quantities and oil specifications for a comprehensive range of makes and models across both refrigerant types.
• 7" colour touch screen provides an intuitive, easy-to-navigate operator interface with clear real-time status information throughout the dual-gas service cycle.
• Thermal printer produces a professional service report for every job, documenting refrigerant quantities recovered and recharged for customer records and workshop accountability.
• Wi-Fi connectivity enables over-the-air software and database updates, ensuring the unit's vehicle coverage remains current for both refrigerant types without requiring a laptop or manual update process.
• 2 pairs of 3m hoses — one set per refrigerant type — provide comfortable reach around the vehicle and prevent cross-contamination between R134a and HFO1234yf circuits.
• Compact and mobile design at 122kg and 91 x 72 x 126cm balances dual-gas capability with workshop mobility, allowing easy repositioning between bays.
• Compatible with optional Gas Identifier to verify refrigerant purity and type before recovery, protecting both refrigerant circuits from contamination by incorrect or mixed gases.
