Heat exchangers, vessels

A heat exchanger is a device that transfers thermal energy from one media to the other in two separate circuits.


Baelz makes heat exchangers in vertical, horizontal and modular designs as well as steam generators, for heat transfer fluids such as steam, condensate, thermal oil, hot water and warm water. All heat exchangers are designed, manufactured and tested according to the European Pressure Equipment Directive 2014/68/EU and the regulations AD 2000.

A broad spectrum of conventional devices including unique modular solutions for steam is available for all types of HVAC, district heating and industrial systems.

As a manufacturer, we are able to offer customized solutions. Steam generators and coolers round off our product range. We also offer pre-assembled skid stations for all types of heat exchanger designs.

Choose from steel, copper and stainless steel tube bundles. If required, we also supply fully stainless steel heat exchangers.

We recommend that the vertical steam-heated heat exchangers are operated with the tried and tested condensate backup control with condensate cooling, in order to keep the energy needed in the processes as low as possible.

Corrosion ▪ Erosion ▪ Cavitation

Wear, erosion and corrosion are always subject to the laws of nature. Thanks to decades of experience, Baelz has plenty of scientifical and practical knowledge allowing to minimize these harmful effects and to ensure low-wear and reliable use of the heat transfer stations in your plants.
