Double-Wall Copper Tube
COBREX Double Walled Heat Exchangers
Shell and Tube Copper Heat Exchangers
Cobrex is a straight, shell and double wall tube, heat exchanger with visual leak detection. A one-pass vertical design, it is constructed entirely of pure copper with internally corrugated tubes, and closely spaced directional baffles, for maximum heat transfer.
Cobrex is an ideal solution for tankless instantaneous, and semi-instantaneous, hot water generation.
Vertical mounting, compact footprint, and lightweight design save space, and reduce time and overall cost of installation.
Features and Benefits
- Double wall tubes and double tubesheet with visual leak detection minimize the risk of cross contamination.
- Option of Victaulic, Flange, or NPT connections.
- 100% copper welded construction offers biofouling resistance and antimicrobial properties, in addition to high thermal conductivity for efficient performance.
- Easily connected in parallel or series arrangements to extend system capacity.
- Counterflow one-pass design, with internally grooved tubes and directional baffles, enhances turbulent flow and increases heat transfer rate
- Flange or Groove/ Weld connections

Unique Double-Wall System
Double wall tube with visual leak detection offers a higher degree of safety in the event of tube wall breach.
COBREX has a unique double-wall corrugated tubes design. The inner tubes are helically corrugated to induce a turbulent flow of the steam that maximizes heat transfer and prevents scaling.
