Pulp and Paper Machinery

The Pulp & Paper Machinery division develops its customers' production processes by designing and manufacturing machinery and components for the paper, board, and pulp industries. The division specializes in rebuilds of paper, board, and pulp drying machines, as well as roll cover services and other servicing. The aim of the services provided by the division is to increase the productivity of the customers' paper and board machinery, to improve the quality of the products, to ensure trouble-free production, and to improve customers' competitiveness. The Pulp & Paper Machinery division offers its customers comprehensive service, which includes design and development; manufacturing, installation, and start-up; and maintenance and spare parts services.

Process Machinery

The Process Machinery division enhances its customers' production processes by designing and manufacturing agitators, pressure vessels – such as columns and reactors – and heat exchangers for process industry applications all over the world. Its customers are companies operating globally in basic industries such as wood processing, metallurgy, the chemical industry, food processing, and the pharmaceutical industry. The companies in the division, which operate in Finland and Germany, represent a strong concentration of expertise in reactors, pressure vessels, and agitator and heat transfer technologies.

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.
