Vipertex® Model 1EHT - Single Phase Flow Cooling Data

Vipertex® model 1EHT tubes provide an approximate 600% increase in heat transfer, which is accompanied by only a small increase in the friction factor.

Vipertex® Model 1EHT - Two Phase Bundle Data - Outside

Vipertex® model 1EHT tubes produce combined overall bundle performance that increases shellside and tubeside heat transfer up to 97%. Enhanced surfaces with cavities on the surface promote nucleate boiling and reduce the required wall superheat for nucleate boiling to occur.

Tubeside Evaporation Results for Smooth, Vipertex® Model 1EHT and Vipertex® Model 1HB Tubes

Evaporation performance using Vipertex® model 1EHT tubes is approximately 1.4 times the performance of smooth tubes.

Tubeside Condensation Results for Smooth, Vipertex® Model 1EHT and Vipertex® Model 1HB Tubes

Condensation performance using Vipertex® model 1EHT tubes is twice the performance of smooth tubes.

Evaporation of R22 and R410a on the Ouside of Vipertex® Model 1EHT Tube

Evaporation performance using Vipertex® model 1EHT tubes is up to 4.4 times the performance of smooth tubes.
