Components » Heat exchangers
Baelz offers heat exchangers for heat exchanging media, such as steam, condensate, hot and warm water.
As a manufacturer we are also able to offer special solutions. A wide range of conventional devices to a world-wide unique modular solution for steam is available for all types of devices in HVAC, distant heating and industry.
Steam generating units, containers and coolers round off the programme.
- baelz 105-S
- The heat exchanger with replaceable upright tube bank.
- baelz 106
- The robust apparatus suitable for all applications. Usually a welded tube bank, also available with replaceable tube bank; almost indestructible; suitable for almost all applications and outputs.
- baelz 107–110
- The apparatus which on account of its large water volume on the water side can be controlled very well also in the partial load region.
- baelz 111
- The universal apparatus has not been fitted with a replaceable tube bank, but has access permanently to the tube plates at the top and bottom; as baelz 112 variant, also suitable for industrial water treatment (parts touching the medium are coated, electroplated or made of VA completely).
- baelz 147
- Made of copper completely; on account of its very small dimensions suitable for replacement for small and medium output. Small dimensions, low price.
- baelz 150
- Like baelz 147, however made of VA completely, thus also suitable for industrial water treatment.
We also offer ready-to-use pre-mounted compact stations for all heat exchanger versions mentioned.
Tube banks are available in steel, copper and stainless steel; apparatuses made of stainless steel completely are also available.
All steam heated heat exchangers are operated by the well-tried condensate impounding control (best possible condensate cooling).
Almost all apparatuses can also be used for the following applications:
Steam - water,
Water - water,
Steam - thermal oil,
Thermal oil - water.
Special variants are available upon request.
Steam - water and water - water tube heat exchanger (upright variant)
