In this special issue, we focus on heat recovery and energy saving – in particular heat pumps. Because of the urgent need to solve global warming and the current energy crisis, totally new technical solutions need to be developed.
Vahterus’ long-term customer UAB Green Group, an engineering company and contractor from Lithuania, has to date installed nine ammonia heat-pump systems to Lithuanian firms, with a total heating capacity exceeding 7 MW. Earlier this year, it supplied a 1.4 MW ammonia heat pump to one of the largest Lithuanian meat-processing plants, Biovela – Utena Meat. The pump has a COP of 7.2 – 8.25, depending on the operating conditions. Vahterus supplied a 1.4 MW Vahterus PSHE Multi-Condenser for the pump, in which an ammonia desuperheater and condenser are integrated in the same shell.
At the end of 2009, technicians at DONG’s combined heat and power plant (acquired by VEKS in May 2012), in Köge, Denmark, contacted one of our distributors about the replacement of an existing heat exchanger. Together, they found great potential for energy saving.

Vahterus provides Plate & Shell Heat Exchanger design for building-heat packages manufactured by Preston Phipps. The compact design makes it possible to manufacture skid assemblies that can handle large loads and take up a much smaller footprint.
In September 2019, Vahterus supplied a critical-charge combined ice-rink chiller, to Ultimate Fabrication Inc, located in Edmonton, Alberta, Canada. The new cooling system was designed with an environmental gain in mind, not only by switching from R-22 to ammonia, but also by maximising electrical and thermal efficiency. The Vahterus PSHE Combined Chiller (a chiller with an integrated separator in one shell) was a key component in the upgrade project of the NHL and studio-size ice rinks in the Cabin John Ice Arena.
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
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
