Internal helical groove structure delivers 30-50% higher heat transfer efficiency. Ideal for AC, heat pumps, and dry-expansion evaporators.
Learn MorePorous / knurled outer surface increases nucleation sites, improving boiling heat transfer coefficient by 50%+. Suited for flooded and falling-film evaporators.
Learn MoreExternal fin structure promotes film condensation, boosting condensing heat transfer coefficient by 40-60%. Ideal for shell-and-tube condensers.
Learn More304/316L/2205 materials offer excellent corrosion resistance, high-temperature performance, and cleanliness for chemical, food, pharmaceutical, and desalination applications.
Learn MoreDefinition: Inner-grooved copper tubes feature spiral grooves on the inner wall. This structure increases the internal surface area and disturbs the refrigerant flow, significantly enhancing the tube-side heat transfer coefficient compared to smooth tubes.
Typical Applications: AC condensers and evaporators, dry-expansion evaporators, heat pump evaporators, refrigeration units
Key Parameters: Outer diameter Ξ¦6βΞ¦25.4mm, groove height 0.10β0.30mm, helix angle 15β35Β°
Definition: Enhanced boiling tubes feature specially processed outer surfaces (porous layer, knurling, dimples, etc.) that increase the number of nucleation sites, significantly boosting the shell-side boiling heat transfer coefficient. Kenergy offers the TE/LE Series (high-performance enhanced boiling) and the LF Series (knurled surface).
Typical Applications: Flooded evaporators, falling-film evaporators, ammonia refrigeration system evaporators
Key Parameters: Outer diameter Ξ¦19.05βΞ¦31.8mm, boiling heat transfer coefficient improvement 50%β100%
Definition: High-efficiency condenser tubes use external fin structures that increase the condensation area on the shell side while the fin tips help thin the condensate film, effectively reducing condensation thermal resistance. Kenergy's TC Series features CFD-optimized fin profiles.
Typical Applications: Shell-and-tube condensers, large industrial heat pump condensers, waste heat recovery systems
Key Parameters: Outer diameter Ξ¦19.05βΞ¦31.8mm, fin height 0.3β0.8mm, condensing heat transfer coefficient improvement 40%β60%
Definition: Stainless steel heat exchange tubes are used in industrial applications involving corrosive media or requiring high levels of cleanliness. Compared to copper tubes, stainless steel offers superior corrosion resistance. Available materials include 304, 316L, 2205 duplex stainless steel, and more.
Typical Applications: Chemical heat exchangers, seawater coolers, food-grade heat exchange equipment, pharmaceutical equipment, power plant auxiliary cooling
Key Parameters: Outer diameter Ξ¦12βΞ¦50.8mm, wall thickness 0.8β3.0mm, surface roughness Ra β€ 0.4ΞΌm (cleanliness grade)
