Series HE-240 Tube-in-Tube Heat Exchanger
VQ-HE240
Heat exchanger, surface 0.3 to 14 m², duty 8 kW to 420 kW.
- SURFACE
- 0.3 to 14 m²
- DUTY
- 8 kW to 420 kW
- DESIGN PRESSURE
- 25 bar
- TEMPERATURE
- -20 to +200 °C
Why it is specified
Quoted against a thermal calculation rather than against an area. The pressure drop on both sides and the fouling allowance that was assumed come with the price, because the assumption is what the argument is usually about.
Typical applications
- District heating substations
- Glycol loop interchange
- Heat recovery between streams
- Process cooling with tower water
Options and executions
- Duplex plates for chloride-bearing water
- Insulation and cladding
- Spare gasket set with the order
- Thermal calculation issued with the quotation
