HygroMatik Pressure steam system DDS.

The HygroMatik pressure steam system DDS System is connected to an existing source of steam, and makes the steam condensation free, which means it can be used in clean rooms and hospitals, for example.


The new HygroMatik DDS is the only system that offers four components in one compact unit; High performance steam separator, strainer, condensate drain and start-up safety switch - all in stainless steel VA. Compact, light, energy-saving.


The DDS can be put together to suit the individual application. The standard flanged connections, compact dimensions and the low intrinsic weight mean it is easy to install - even in challenging installation conditions.


The HygroMatik DDS humidifies using condensate-free saturated steam,which means it offers the shortest possible humidification distances.

Product description

Replaceable dirt trap.

The high quality stainless steel dirt trap protects the control valve and the condensate drain against dirt from the steam network. The inner, fine-mesh coarse strainer can be simply exchanged.


High-performance steam dryer.

The stainless steel DDS steam dryer separates condensate from steam using a spiral piping system. Thanks to the low weight and the compact closed system, the HygroMatik DDS is easy to assemble and highly energy efficient.

Reliable start-up protection.

The start-up protection enables humidification only once a defined operating temperature has been reached. This effectively prevents the penetration of condensate from the steam network into the air conditioning duct.

High-performance condensate drain.

The robust, tightly closing ball float condensate between drain channels away any condensate. Due to the fast-response principle and the high capacity, large quantities of condensate can also reliably be drained away, e.g. during system start-up. In this way the closed system prevents any loss of steam.


Optimally adjusted.

The bus-compatible actuator offers optimum automatic control by means of direct connection without an adapter. The special metal-to-metal or soft sealing HygroMatik control valve regulates the steam quantity by means of valve travel with an equal percentage characteristic curve. This means particularly fine control in the lower range and a quick response to a higher humidity requirement in the upper control range.

Stainless steel steam lances.

Steam lances from stainless steel have a low net weight and are quickly fitted. The quiet steam outlet nozzles take the steam centrally from the driest area of the steam lance. The alignment of the nozzles against the air flow ensures quick distribution and a short absorption distance.


The inner, closed steam lance heating system is arranged at the lowest point of the steam lance. This means that any condensate which may possibly arise can immediately be revaporized. The energy optimized control results from the light, maintenance friendly thermic condensate drain. Any unnecessary temperature rise of the channel caused by an irregular steam output is avoided.
