Steam distribution systems

Ultra-Sorb® vapor distribution system

Irregular steam discharge in air ducts leads to local oversaturation, condensate formation and increased demands on the installation section. The Ultra-Sorb® steam distribution system introduces steam into the flow profile over a large area via several thermally insulated dispersion lances and enables controlled, condensation-free absorption within short duct sections.

The Ultra-Sorb® steam distribution system is designed for applications with a high humidity increase and low supply air temperature. The integrated evaporation of the condensate produced and its return on the pressure side reduce heat losses and avoid external discharges. This ensures stable integration in ventilation and air conditioning systems with limited installation space.

Technical features:
  • Uniform steam injection across the entire duct cross-section
  • Shortened absorption distance even with high steam loads
  • Suitable for pressurized steam applications from 35 kPa (depending on model)
  • Integrated condensate management
  • Designed for industrial air conditioning systems

The distribution of the steam flow to several dispersion lances reduces local moisture concentrations and supports uniform mixing with the air flow. The thermally insulated design limits condensate formation in the distribution system and increases energy efficiency.

Questions and answers about the Ultra-Sorb® vapor distribution system

In the following section on the Ultra-Sorb® steam distribution system, we provide a compact overview for planning and procurement. Technical reasons for short absorption distances and steam distribution in the air duct with a high humidity increase and low supply air temperature are discussed. We also explain how the system handles condensate internally and what consequences this has for maintenance and operation. You will also find specific performance data on steam throughput and pressurized steam from 35 kPa and information on typical installation conditions in HVAC systems, central air conditioning units and process air systems.
