Cobrex Double Wall Heat Exchanger

Shell and Tube Copper Heat Exchanger

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.

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
  • Vertical mounting, compact footprint, and lightweight design save space , and reduce time and overall cost of installation
  • Easily connected in parallel or series arrangements to extend system capacity
  • 100% copper welded construction offers biofouling resistance and antimicrobial properties, in addition to high thermal conductivity for efficient performance
  • Counterflow one-pass design, with internally grooved tubes and directional baffles, enhances turbulent flow and increases heat transfer rate
