SUN Q-Tech IV HD-Truck R134a Fully Automatic Aircon Service Unit

Engineered specifically for heavy-duty truck, bus, and agricultural vehicle workshops that service large-capacity aircon systems requiring significantly higher refrigerant volumes than standard passenger car units, the SUN Q-Tech IV HD-Truck R134a Fully Automatic Aircon Service Unit delivers fast, accurate recovery, recycling, vacuum, and recharging — with a 40-litre refillable cylinder, high-speed refrigerant pump, and 6-metre hoses designed for the practical demands of a commercial vehicle workshop environment.

Key Features:

• Heavy-duty truck and bus aircon servicing capability handles the large refrigerant volumes required by commercial vehicle, agricultural, and industrial aircon systems that would exceed the capacity of a standard passenger car aircon service unit.
• Fully automatic operation manages the entire recovery, recycling, vacuum, and recharge cycle without manual intervention, reducing operator errors and maximising throughput in high-volume commercial vehicle workshops.
• 40-litre refillable refrigerant cylinder provides the large refrigerant capacity needed for truck and bus aircon systems, significantly reducing the frequency of cylinder refills during a busy workshop day.
• 1kg/min refrigerant pump delivers high-speed refrigerant transfer during the recharge phase, reducing charge time on large commercial vehicle systems and keeping vehicle downtime to a minimum.
• 170 l/min vacuum pump capacity at 0.1 mbar achieves deep vacuum rapidly on large-volume commercial vehicle aircon systems, ensuring thorough moisture removal before recharging.
• 300g/min recovery speed handles the high refrigerant volumes recovered from truck and bus systems efficiently, minimising the time spent on the recovery phase.
• 2 dedicated filters — one for each direction of refrigerant flow — protect the unit's internal components from contamination during recovery and recharge, extending service life in demanding commercial workshop environments.
• 1 oil + 1 dye refillable container with automatic dye injection allows PAG oil and UV dye to be introduced precisely during the service cycle, supporting leak detection and system lubrication on commercial vehicle aircon systems.
• Automatic dye injection introduces UV dye into the system during the service cycle without manual intervention, enabling subsequent UV leak detection without additional equipment handling.
• Vacuum leak check verifies system integrity before recharging, identifying leaks that would cause premature refrigerant loss and repeat service call-backs on commercial vehicles.
• Vehicle database covering car, truck, and agricultural vehicles provides OEM refrigerant charge quantities and oil specifications across a comprehensive range of commercial and passenger vehicle makes and models.
• 6m hose length provides the extended reach required to connect to truck and bus aircon service points without repositioning the unit, accommodating the larger footprint of commercial vehicles in the workshop bay.
• LCD display (123 x 40mm) provides clear operational status readouts throughout the service cycle in the demanding lighting conditions of a commercial vehicle workshop environment.
• Thermal printer produces a professional service report for every job, documenting refrigerant quantities recovered and recharged for customer records and fleet maintenance accountability.
• Pressure leak check (nitrogen) verifies system integrity after recharging, confirming the aircon system is sealed and ready for service before the vehicle is returned to the customer.
• Compatible with optional Gas Identifier to verify refrigerant purity and type before recovery, protecting the unit from contamination by incorrect or mixed refrigerants encountered in mixed commercial vehicle fleets.
