Hi-Tech is  the pioneers in the field of  shell & Tube  heat exchangers and Double Pipe type Heat Exchangers  which include a typical industrial heat exchanger in all characteristics, air heat exchanger etc.  Shell & Tube heat exchangers offer large surface area in combination with efficient heat transfer and compactness. These are widely used in industries for various duties like cooling, heating, condensation, evaporation etc.    The Shell & Tube heat exchangers consists of straight copper tube bundle supportes with S.S. plates or fiver plates .The  aftercooler is cylinderical tank filled with air coils. in both air is cooled by circulating air. Heat Exchangers for sea water marine application or with steels shells are also offered & designed as per customer specific requirements.
