SUN Q-Tech IV R134a Fully Automatic Aircon Service Unit

Engineered for professional automotive, truck, and agricultural workshops that demand a fast, accurate, and fully featured R134a aircon service solution, the SUN Q-Tech IV R134a Fully Automatic Aircon Service Unit delivers complete refrigerant recovery, recycling, and recharging in a single automated cycle — with built-in leak checking, hybrid vehicle support, and Wi-Fi connectivity for seamless software updates and database access.

Key Features:

• Fully automatic operation with automatic air purge manages the entire recovery, recycling, vacuum, and recharge cycle without manual intervention, reducing operator errors and speeding up aircon service turnaround time.
• R134a refrigerant compatibility covers the full range of passenger cars, light commercial vehicles, trucks, and agricultural vehicles that use R134a refrigerant, making it the ideal all-round aircon service unit for mixed-fleet workshops.
• Heated cylinder ensures consistent refrigerant density during the recharge phase, improving charging accuracy and reducing the risk of under- or over-charging the vehicle's aircon system.
• 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.
• 300g/min recovery speed with a 12-litre refillable refrigerant cylinder minimises vehicle downtime during the recovery phase, keeping workshop throughput high.
• 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, supporting leak detection and system lubrication without manual intervention.
• Hybrid vehicle function enables safe aircon servicing on hybrid and electric vehicles, which require isolation from high-voltage systems during refrigerant handling — extending the unit's capability to modern vehicle fleets.
• Oil change procedure flushes old compressor oil from the system and replaces it with the correct quantity of fresh PAG oil automatically, ensuring accurate oil management on every service.
• 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, ensuring accurate, manufacturer-compliant servicing.
• 7" colour touch screen provides an intuitive, easy-to-navigate operator interface with clear real-time status information throughout the service cycle.
• Thermal printer produces a professional service report for every job, documenting the 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 without requiring a laptop or manual update process.
• Status light provides at-a-glance visual confirmation of unit status, allowing the technician to monitor the service cycle from across the bay.
• 3m hose length provides comfortable reach around the vehicle without the need to reposition the unit during the service cycle.
• Compact and mobile design at 77kg and 76 x 70 x 125cm allows easy repositioning between bays, keeping the unit accessible wherever it is needed in the workshop.
• Compatible with optional Gas Identifier to verify refrigerant purity and type before recovery, protecting the unit from contamination by incorrect or mixed refrigerants.
