With the deep implementation of global carbon neutrality strategies and the enforcement of new energy efficiency standards, the refrigeration industry—including air conditioning, refrigerators, and commercial compressors—is rapidly upgrading toward higher efficiency, reliability, and environmental friendliness. In the critical quality control phase of refrigeration system manufacturing, the vacuum process directly determines refrigerant purity, system sealing, and the overall service life of the equipment. As a specialist in vacuum technology solutions, we understand that a superior vacuum environment is the foundation of high-quality manufacturing.

The TDV Series Two-Stage Rotary Vane Vacuum Pump is engineered to meet these rigorous demands. Featuring ultra-high vacuum capabilities, strong water vapor resistance, and stable continuous operation, this series covers the full spectrum of applications from automated production lines and leak detection to refrigerant charging and after-sales maintenance.

1. Solving Industry Pain Points: Eliminating "Ice Blockage" at the Source

Refrigeration systems are highly sensitive to residual air and moisture. Even trace amounts of impurities can lead to "ice blockage," pipe corrosion, reduced heat exchange efficiency, and refrigerant degradation. The TDV Series utilizes a dual-stage oil-sealed structure combined with a gear pump forced lubrication design, achieving an ultimate vacuum of ≤0.1Pa. This performance far exceeds industry standards. Equipped with an adjustable gas ballast valve, it efficiently strips moisture and condensable gases during the pumping process, solving the common issues of emulsification and instability found in traditional pumps.

2. Comprehensive Model Matrix: Precision Matching for Every Scenario

To meet the diverse production capacities of the refrigeration industry, the TDV Series offers a complete product lineup for industrial vacuum equipment needs:

• Micro/Single Station (TDV-4/8/16): Compact and fast-responding, ideal for household AC, refrigerators, and small compressor units.
• Large-Scale Production Lines (TDV-24/30/48/65/90): Designed for 24-hour continuous operation, supporting multi-station centralized evacuation in high-load automated environments.
• Heavy-Duty Refrigeration (TDV-275): With a pumping speed of up to 255m³/h, it is specifically designed for large cold storage units, centrifugal chillers, and industrial refrigeration systems, significantly shortening evacuation cycles.

4. Five Core Advantages for Harsh Environments

The high-performance vacuum pumps in the TDV range are engineered for the high-humidity and solvent-rich conditions of refrigeration workshops:

• Dual Anti-Suckback: Integrated automatic valves prevent oil from contaminating the refrigeration system.
• Water Vapor Resistance: Multi-stage gas ballast handles high humidity without oil emulsification.
• High Stability: Integrated cylinder block and forced lubrication ensure reliability under heavy loads.
• Low Maintenance: Air-cooled design with IP54 protection and Viton seals for harsh environments.
• Eco-Friendly: Quiet operation (as low as 52dB) aligns with modern green factory standards.

5. The Reliable Partner for Helium Leak Detection

In the stringent quality control phase, the TDV Series serves as the perfect backing pump for helium mass spectrometry leak detection. Its low oil-backflow and clean vacuum characteristics provide a stable environment for detecting minute leaks in evaporators, condensers, and compressor shells, ensuring the safety and longevity of the final product.
