SPIRAL WOUND FINNED TUBE |
| |
| Fins are basically external surfaces on tube for increasing the surface area of the bare tube, resulting in a compact Heat Exchanger. |
| |
| The method of attaching the fins over tube is of prime importance, since even a slightest air gap between the tube and fins will defeat the whole purpose of fins over the tube. |

| |
| HEFT was formed in 1994 to provide the service to petrochemicals, power generation, chemicals, pharmaceuticals industries with high quality HELICAL WOUND FINNED HEAT EXCHANGERS tubing used in the maintenance and manufacture of the air cooled heat exchangers, air heaters & other related heat exchangers. |

AIR COOLED HEAT EXCHANGER |
| |
| Heft Engineers are specialized in to design and manufacturing of AIR COOLED HEAT EXCHANGER, using in-house manufactured finned tubes. |
| |
These heat exchangers offer following advantages over other conventionl & crimped type finned tube Heat Exchangers.
- More surface area per square feet of heat exchanger
- Lower air resistance, resulting in less power to deliver the requires C.F.M.
- Reduction in number of tubes for given B.T.U. transfer per rate area, resulting in fuel saving
- Light weight easier handling
- More fins per inch can be incorporated on entire tube length
|
| |
| The combination of low friction air loses/ high air velocity and maximum heat transfer per square feet of face area results in extremely high heating or cooling capacity of heat exchanger in a given space. |

| MULTISTAGE HEAT EXCHANGERS FOR CHILLER CONDENSERS |
| |
| Multistage Heat Exchangers are specially designed for refrigeration application, features and performance characteristics that make the difference. their compact sizes makes them easy to package and install, saving time and money over Shell & Tube Heat Exchangers. |
| |
| When performance counts, the professionals specify Multi-stage heat exchanger, the standard for compact, high efficiency multi stage heat exchanger technology. Multi stage heat exchangers are available in a variety of sizes for refrigerant application with capacity 1/2 tons to 10 tons. |
| |
| Multi Stage Heat Exchangers are upto 50% smaller than traditional shell & tube heat exchanger. |
