Baelz-thermodynamic®
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.

At a height of around 900 mm and weighing in at max. 20 kg per module, these single material heat exchangers offer high performance despite their compact size. The use of steam manifolds means that modules can easily be exchanged, added or removed, enabling a flexible load capacity and minimizing downtime.
Advantages of the modular technique
- Lightweight and compact design
- Lower consumption of primary energy due to especially low heat loss
- Better part load adaptation
- Quick exchange of individual modules, e.g. for cleaning purposes, makes for optimal availability of the installation
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.
The following brochure gives information about
- Required chemical standards for the quality of steam and water in Baelz systems
- Criteria for selecting materials for the heating surfaces
- Causes and prevention of corrosion, erosion and cavitation
