Glass Heat Exchanger

We make available our Glass Heat Exchanger in two categories, namely Coil type and Shell & Tube type. It can be used for variety of applications such as condensation, cooling, heating, boiling and suitable combinations of the above. Moreover, the selection of equipment depends upon the type of application, heat load, availability of heating/cooling media and various other factors. Moreover, our Glass Heat Exchanger is reasonably priced.
Functioning :
In all types of glass Heat Exchangers the heat transfer is through the wall of the glass tube. The heat transfer co-efficient can be of a moderate order because of low wall thickness. With 1.5 mm thick walled tubes, the wall heat transfer co-efficient is about 725 Kcals/hr m2^oC and we can obtain an overall heat transfer co-efficient for steam condensation with water-cooling as about 550 Kcals/hr m2^oC. The allowable pressure inside the tubes can be vacuum to 3 kg/cm2 while that on the domes as well as on the shell depends upon the size of the shell corresponding to the values mentioned in technical specifications. The Heat Exchangers can safely be used up to 150^oC with the limitations of thermal shock up to 120^oC and temperature gradient across the wall less than 50^oC. The shell side pressures on metallic shell & tube heat exchangers can be as high as 2.5 kg/cm. For higher pressure requirement up to 4 kg/cm2 , the PTFE tube sheets need redesigning and can be made on special request.
Available Types :

• Coil Condensers
• Product Coolers
• Immersion Heaters
• Boilers

Coil Condensers, Information
Composed completely of glass, coil heat exchangers are typically used as vapor condensers and liquid coolers. They are usually designed and installed as an integral part of a vertical column. To provide a reliable corrosion resistant internal seal, the coil battery is sealed to the jacket, creating a single unit. Boilers and immersion heaters are also available in this all-glass coil design.
Other   Designs
We also offer glass cascade coolers, bayonet and jacketed-type heat exchangers. For further information on these special application models, please contact us.
Technical  Data

• Heat Transfer in Condensers
  The heat transferred in coil condensers con be considered generally as 55 Btu/hr-ft2-^oF for any unit. This figure may vary from 10 to 72 Btu/hr-ft2-^oF depending on the fluids involved and the operating conditions.
