Industrial Heat Transfer & Cooling Tubes

Industrial heat transfer and cooling tubes are the core components of shell-and-tube heat exchangers, widely used in central air conditioning chillers, industrial cooling systems, chemical processing, power plant auxiliary cooling, seawater desalination, and food & pharmaceutical industries. Industrial applications impose much higher demands on pressure rating, temperature tolerance, corrosion resistance, and thermal performance compared to standard HVAC tubes. Kenergy offers professional solutions for four key application areas:

Flooded Evaporator Tubes (TE/LE/LF Series) — Used in flooded evaporators where tubes are fully immersed in refrigerant or secondary coolant. The enhanced surface structure promotes nucleate boiling heat transfer. TE/LE series feature high-efficiency enhanced boiling surfaces, while LF series are wire-wound tubes. Both deliver 50%+ improvement in boiling heat transfer coefficient compared to smooth tubes. Ideal for central chiller plants and large-capacity industrial chillers.

Shell & Tube Condenser Tubes (TC Series) — Designed for shell-and-tube condensers where high-temperature, high-pressure refrigerant vapor condenses on the shell side. Kenergy's TC series high-efficiency condenser tubes use external fin structures to promote film-wise condensation, delivering 40-60% higher condensation heat transfer coefficients versus smooth tubes. Suitable for large chillers, industrial heat pumps, and waste heat recovery systems.

Falling Film Evaporator Tubes — Used in falling film evaporators where liquid is evenly distributed over the tube bundle surface to form a thin film. Our falling film evaporator tubes feature optimized surface geometry and wetting characteristics to ensure uniform film coverage and prevent dry spots. Applicable in central air conditioning, seawater desalination, food concentration, and chemical evaporation processes.

Stainless Steel Tubes for Industrial Heat Exchangers — Designed for corrosive media or applications requiring high cleanliness, such as chemical acid/alkali handling, seawater cooling, food-grade heat transfer, and pharmaceutical equipment. Material grades include 304, 316L, and 2205 duplex stainless steel, offering superior chloride corrosion resistance compared to copper tubes. Available in smooth, internally grooved, and externally finned surface forms, customizable for specific operating conditions.
