On the humidification test bench

The development and optimisation of humidifiers requires extensive testing.
For this purpose, we have developed a humidification test bench on which the air mass flow as well as the air conditions at the humidifier inlet can be reproducibly adjusted. The air conditions at the humidifier inlet and outlet are recorded by a close-meshed grid of humidity, velocity and pressure sensors and processed through a specially developed measurement data acquisition system.
On the basis of numerous test series, it is possible to further refine the calculation models for the design of our air washers.
Important design parameters such as circulating water quantity, overall construction length and nozzle pattern can thus be determined precisely for the respective specified operating conditions.
Uneconomical designs with increased energy consumption/water loss and oversized humidification sections are thus avoided by refinement.
Our medium-pressure and high-pressure humidifiers have also been examined on the test bench during all stages of development, from the initial concept to endurance testing.
The testing undertaken helps to establish new findings in relation to nozzle technology, nozzle alignment, separation efficiency / post-evaporation effect of the agglomerators as well as the influence of any supplemental turbulators.
Likewise, different control and regulation concepts can be tested to ensure reliable, hygienic and efficient operation. This includes, for example, a comparative consideration of intermittent and modulating operation of the water injection system to determine the effect if any on water use efficiency.
Perhaps there are also certain design parameters under critical operating conditions for which you require verification during real-time system operation.
With our test facility we can offer you a wide range of services.
This includes the general examination of the humidifier design as well as determining the performance limits of the humidifier, the effect of disturbances on the air inflow or the metrological determination of the water loss ratio under specified operating conditions. We welcome such scrutiny. Because our systems deliver what we promise!
