Introduction

RVBH Series Tank-Type Heat Exchangers (1–15 HP)

Compact • High Efficiency • Reliable Performance

The RVBH Series Tank-Type Heat Exchangers are engineered to deliver powerful heat transfer in a compact footprint. Compared with traditional heat exchangers—dual-pipe (oversized), plate-type (easy to block/frost crack), and shell-tube (large and costly)—the RVBH Series offers a superior balance of size, efficiency, and reliability.

A free-flow water path and bottom-position water inlet improve drainage, reduce sediment buildup, and ensure long-term stable operation. The RVBH Series can be used as a condenser, evaporator, or multi-media heat exchanger across various HVAC applications.

Key Advantages

High-Performance Heat Exchange Core
- Available with high-efficiency cores or anti-corrosion swimming-pool versions based on customer needs.
Compact & Durable Design
- Ideal for central air-conditioning chillers, air/water source heat pumps, swimming-pool systems, and more.
Leak-Resistant Water Circuit
- Seamless coil design eliminates welding joints and minimizes leakage risk.
High Safety Assurance
- Each unit undergoes a 4.2 MPa pressure test to guarantee safe and reliable performance.
Flexible System Integration
- Units can be connected in parallel or series to support larger system capacities.

Technical Edge

High Heat Exchange Efficiency
- The RVBH Series uses high-efficiency heat exchange tubes that provide up to four times the surface area of conventional tubes. The compact, precisely engineered coil structure ensures optimal refrigerant flow and maximum heat transfer performance.
Enhanced Safety & Reliability
- A unique double-helix water channel design delivers smooth, uniform water flow, preventing ice blockage and scale formation. The bottom-positioned water inlet allows complete drainage, protecting the coil from freezing when the system is shut down.
Compact Design
- Its small footprint makes system layout easier and helps reduce the overall size and cost of the complete unit.
Efficient Oil Return
- Special internal flow design ensures smooth and continuous oil recovery, improving system stability and long-term reliability.
