New Vahterus Multi-Condenser in 1.4 MW Heat Pump in Lithuania

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.

How We Work

Top Quality For Demanding Conditions

The welded plate pack is the core of the Vahterus heat exchanger. The welding is of the highest quality, ensuring maximum durability.

Without a plate pack, you wouldn’t have a heat exchanger, only a pressure vessel. Vahterus heat exchangers have no gaskets because their structure is completely welded. In order for the heat exchanger to work as planned, the welding must be of the highest quality. Vahterus’s welding engineer Tuomas Hokkanen and quality engineer Lassi Forsström explain that the key to ensuring this is continuous improvement of methods and strict quality control.
