Custom Double-Walled Copper Coil Heat Exchanger

The double-walled copper coil heat exchanger is a specialized design developed to provide maximum safety and efficiency in heat transfer systems where fluid separation is critical. It is widely used in applications such as potable water heating, medical systems, food processing, and refrigerant circuits where even a minor fluid leak must be immediately detectable.

Design and Construction

Each heat exchanger is built with two concentric copper tubes - an inner and an outer wall - forming a protective double barrier between the working fluids.
If a leak occurs in the inner tube, it escapes through the vented space between the two walls rather than contaminating the other fluid circuit. This ensures safe operation and full compliance with hygiene and safety regulations.

The coil configuration provides a large heat transfer surface area within a compact footprint, while copper's excellent thermal conductivity guarantees rapid and efficient heat exchange performance.

Key Features

Double-walled safety design - prevents cross-contamination between fluids.

High thermal conductivity - copper offers superior heat transfer efficiency.

Compact and customizable - coil diameter, length, and wall thickness can be tailored to project requirements.

Corrosion resistance - suitable for fresh water, glycol, and various industrial fluids.

Easy maintenance and inspection - vented design allows leak detection and cleaning access.
