Air Conditioner and Refrigerant Recovery Device | VRR24L

The VRR24L is a professional refrigerant recovery unit designed for durability and high performance. It features an oil-less compressor, allowing it to handle various types of refrigerants without the need for oil changes. It is specifically engineered to operate in heavy-duty environments and large-scale service centers.

1. Key Features

• Oil-less Compressor: Enables the recovery of multiple refrigerant types without contamination and requires minimal maintenance.
• Self-Purging Function: Prevents cross-contamination of different refrigerants and ensures a clean system after every operation.
• One-Knob Operation: Features a user-friendly interface that allows users to switch between functions seamlessly.
• High-Pressure Protection: Equipped with a safety switch that automatically shuts down the unit if pressure exceeds 38.5 bar (558 psi).
• Large Condenser: Ensures high-efficiency cooling and accelerates the recovery process even in high-temperature conditions.
• Durable Construction: Compact design with ergonomic handles for easy portability across work sites.

3. Usage Method

1. Preparation: Ensure the device is connected to a grounded power source. Connect the hoses between the cooling unit (e.g., AC), the device filters, and the recovery tank.
2. Starting Recovery: Open the valves on the recovery tank and hoses. Turn the main knob to "START" and then to "RUN".
3. Pressure Monitoring: Observe the pressure gauges on the interface (Internal and External pressure).
4. Self-Purge: After the recovery process is complete, turn the knob to "PURGE". This step is essential to clear residual gas into the tank, protecting the unit and preventing future contamination.
5. Shutting Down: Once the pressure drops to the required vacuum level, turn off the device and close all valves.

4. Additional Notes

• The unit is equipped with a Filter Drier; it must always be used to protect the compressor from moisture and impurities.
• Includes a built-in air cooling system (cooling fan) to maintain stable performance during continuous operation.
• An ideal choice for HVAC technicians looking for a balance of speed and reliability.
