The functional enhancements of the outer surfaces of the GEWA-B, PB, and Turbo-B/E tubes have been optimized for bulk boiling of refrigerants and similar fluids. Coupled with ideally matched surfaces on the inside of the tubes, optimum heat transfer coefficients can be achieved. GEWA and TURBO Evaporator Tubes are available with outer and inner surfaces adapted for specific needs of your application.

GEWA

• B5 & B6 – For highest performance and efficiency
• B4HSL – For weight optimized alternatives as a "drop-in" solution
• BHV – For media with high viscosities
• BLF | BPL – For applications with high fouling tendency

TURBO

• B – The original boiling tube
• ESP – Efficient and lightweight
• EHPII – The industry standard boiling tube
• EPT – High efficiency in ferrous alloys
