Shell & Tube Type Heat Exchangers

SHELL & TUBE TYPE HEAT EXCHANGERs/coolers

Thermo Engineers Pvt Ltd has developed expertise in design and manufacturing of wide range of Shell and Tube Heat Exchangers with an experience of over 30 years.We have supplied more than 20,000 Shell & Tube type Heat Exchangers which are successfully being used as Oil coolers, Inter Coolers, After coolers, Gas Coolers, Water to Water Coolers, Transient Heaters, Chillers, Condensers, Evaporators, Stream Heaters, Pre Heaters etc. With our efficient in-house design, inspection and prototype testing facility we have achieved excellence in delivering efficient and cost effective Shell and Tube Heat Exchangers for all our customer requirements which meet all the required industry standards and specifications.

A.Fixed Tube Type
  • Most economical
  • Tubes can be cleaned & examined easily from inside.
  • No chance of intermixing of shell side and tube side fluids because of gasket of packed joint failures as these are always welded.

B. Floating Head Type
  • Complete tube bundle can be removed for inspection and maintenance
  • The tubes can be cleaned from outside as well as inside.

double wall type heat exchangers/coolers

Our Double wall type coolers are designed and manufactured with special care where transformer oil cooling is a critical application. Because we understand that failure in transformer due to cooler leakage may lead to heavy financial losses.

Unlike single tube coolers, this execution of the tube bundle requires double tubes. This special safety design prevents the chances of water and oil mixing in heat exchanger and also the cooling water pressure is not limited by oil pressure. Also the processes need not to be terminated immediately after the failure. Thus keeping the transformer in service. In case of leakage, water or oil is led into the chamber between tubes and the tube plates, therefore the double tube system always prevents water and oil from mixing.The double tube design is the most valid solution to protect the transformer, especially when, using sea or industrial water, and where the site maintenance is not easy. In case of leakage an alarm is provided to a leakage detector provided at the collecting box fitted to the cooler.
