Koss custom builds shell and tube heat exchangers in straight or U-tube configurations.
Straight Tube Heat Exchangers:
- 4", 6", 8", 10" and 12" body diameters
- Body lengths from 2 to 20 feet
- 316L stainless steel construction
- Clamp and welded body connections
- Easy access to tubes, for cleaning and inspection
- Ideal for high GPM (gallons per minute) rate applications
- Loved for their simplicity and versatility
- Double and triple tube models available
- Optional insulation (with stainless steel welded covering)
U-Tube Heat Exchangers:
Compared to straight tube heat exchangers, U-tube models are designed to make allowances for thermal expansion. We see less weld fatigue and reduced risk to the rest of the machine resulting in a longer lifespan.
- ASME certification available
- 4” or 6” body diameters
- Body lengths from 2 to 20 feet
- 304 and 316L stainless steel construction
- Clamp and welded body connections
- Optional insulation (with stainless steel welded covering)
Meet or exceed USDA sanitary standards.
More about shell & tube models
In these types of heat exchangers, two fluids exchange heat. One fluid is referred to as the tube-side fluid (which goes through the heat exchanger inside the tubes) and the other is the shell-side fluid (which goes through the heat exchanger in the shell, outside the tubes).
A straight tube heat exchanger is easier to clean than a U-tube heat exchanger, making it a better choice when the tube-side fluid could have a tendency to foul the tubing and require more regular maintenance.
The U-tube heat exchanger works well when the tubes and shell will have different thermal expansion characteristics because it can allow the tube and the shell to expand or contract independently.
