In order to supply its clients with the best possible heat exchanger solutions, Vahterus designs the exchangers together with the client from beginning. In addition to functional requirements, heat exchangers must fulfil statutory pressure equipment regulations, as well as the client’s own specific requirements. In order to do this, Vahterus has invested heavily in developing its own sizing software.

Innovative Refrigeration Systems provides turnkey design and building services and Industrial refrigeration systems. Vahterus has been their partner in supplying heat exchangers since 2010. When their customer, United State Cold Storage, wanted to increase its blast freezing capacity in Dallas market, Innovative Refrigeration looked to Vahterus for reliability on performance and delivery. The project was realised in three phases, with the initial systems installed in 2013, and the later expansion in 2014 and 2016.

High operating pressures require premium quality

When the Vahterus Plate & Shell heat exchangers entered the market in the early 1990s, the refrigeration industry was in the process of slowly taking a new direction. Previously considered rather conservative by some, the industry started seeing an increasing demand for components compatible with natural refrigerants. The promotion of the use of natural refrigerants was spurred by the need to phase out ozone-depleting freons, which cause climate change.

Vahterus supplied a total of five heat exchangers to a heating plant constructed in 2015. The Vahterus heat exchangers help make the plant more efficient while reducing the plant’s carbon footprint and construction costs.

For a chemical plant in Antwerp, Kapp received an order for two separate Vahterus Plate & Shell Heat Exchangers. The applications for the heat exchangers are not extremely difficult however the end user is very pleased to have found this type of heat exchanger which is completely new to this plant.

Tailored solution

This typically Dutch story dates back to 1937, when the Dutch government decided to build a dike between the cities of Lemmer and Urk to claim extra land for agriculture. In 1940, the dike was closed, and the land subsequently pumped dry. This new land, called Noordoostpolder, officially became dry on September 9, 1942.

Even the most reliable heat exchangers occasionally need to be serviced. So when a customer had trouble with a plate pack which hadn’t been serviced for eight years, they turned to Vahterus Service for help.

The use of recycled raw material as the basis for motor oil is increasing in Europe. “Customers have also started to request recycled products here. In North America, the market already prefers recycled motor oils,” explains Managing Director Petri Rautanen from L & T Recoil Oy.

Botash is the largest producer of natural sodium products in Southern Africa, yet they’re always looking for ways to improve their operations. They chose Vahterus Plate & Shell Heat Exchangers and instantly saw an increase in their production yields. Botash (Botswana Ash (Pty) Ltd.) is located in Sua Pan in the north eastern part of Botswana, about 180 kilometres from Francistown. Since starting their operations in 1991, they’ve grown to become the largest producer of natural sodium products in the Southern African region and they currently have a production capacity of 300 000 tonnes of soda ash (sodium carbonate) and 420 000 tonnes of salt (sodium chloride) per year. Botash now has offices in South Africa and Zambia, and the company’s vision is to be Africa’s supplier of choice for natural sodium products.
