Spiral Heat Exchangers
Vaahto has more than 50 years experience in the engineering and fabrication of Spiral Heat Exchangers. There are several kind of industries worldwide utilizing Vaahto Heat exchangers.
Their experience in designing and manufacturing combined with innovative ideas makes the Spiral Heat Exchangers an exceptional heat exchanger providing superior properties in heat transfer, condensation and evaporation.
Shell & Tube Heat Exchangers
The Vaahto Group manufactures all types of shell and tube heat exchangers. Modern production methods for baffle cutting and tube fixing guarantee a high product quality. The largest heat exchangers manufactured have more than 15000 tubes and diameters of over 5 m.
Plate & Frame Heat Exchangers
Plate and Frame heat exchangers have become a viable alternative to shell-and-tube heat exchangers. The plate-type heat exchanger, has an ability to optimize thermal performance and has made close approach and temperature cross applications economically feasible where shell-and-tube designs have not. Applications for this easily maintained product are many but in general plate and frame type exchangers are suited for low temperature, clear fluids, and relatively high pressure drop situations.
