Design and Build Quality

Compact Yet Robust Construction

The HNZXIB refrigerant recovery machine is built with practicality in mind. Its compact dimensions allow it to fit easily into service vehicles or workshop spaces, while its sturdy construction ensures durability during frequent use.

The use of stainless steel and copper in critical components enhances heat transfer and resistance to wear. This is especially important in high-demand environments where the machine operates for extended periods.

Portability for On-Site Work

Weighing approximately 12 kilograms, this unit strikes a balance between portability and stability. It is light enough for technicians to carry between job sites but solid enough to remain stable during operation.

Performance and Efficiency

Powerful 3/4 HP Motor

The heart of the machine is its 3/4 HP motor, which delivers consistent performance across different recovery tasks. This power level allows it to handle both small residential systems and more demanding commercial applications.

Multi-Mode Recovery Capabilities

The machine supports three recovery modes:

• Vapor Recovery: Ideal for standard maintenance tasks
• Liquid Recovery: Faster for systems with large refrigerant volumes
• Push-Pull Mode: Maximizes efficiency in high-capacity systems

These options provide flexibility, allowing technicians to adapt to various scenarios.

Recovery Rate Performance

The recovery rates are competitive for a unit of this size:

• Gaseous recovery: Up to 0.319 kg/min
• Liquid recovery: Up to 5.42 kg/min
• Push-pull mode: Up to 14.38 kg/min

This performance ensures reduced downtime and faster job completion.

Cooling System and Heat Management

Air-Cooled Operation

The built-in air-cooled system ensures that the machine operates efficiently under normal conditions. It maintains stable temperatures without requiring additional equipment.

Optional Water Cooling Enhancement

For more demanding tasks, the machine supports water cooling. This feature significantly improves heat dissipation, allowing for extended operation without overheating.

Proper water level management is essential for optimal performance, as specified in the operational guidelines.

Ease of Use and Operation

Straightforward Setup

The HNZXIB recovery machine is designed with simplicity in mind. Once the hoses and connections are properly installed, the system operates smoothly.

Technicians are advised to ensure all pipelines are securely connected before starting the recovery process. This minimizes the risk of leaks and improves efficiency.

User-Friendly Operation

The controls are intuitive, making the machine accessible even for technicians with moderate experience. However, professional knowledge of HVAC systems is recommended for safe and effective use.

Safety Features

High-Pressure Protection

The built-in high-pressure cutoff system automatically shuts down the machine if pressure exceeds 551 psi. This protects both the equipment and the operator.

Oil-Free Compressor Benefits

The oil-free design eliminates the risk of oil contamination in recovered refrigerant. This not only improves system cleanliness but also reduces maintenance requirements.
