WE HUMIDIFY THE AIR.

HygroMatik Pressure steam system DDS.

The HygroMatik pressure steam system DDS is connected to an existing steam network and makes the pressurised steam available for energy-efficient air humidification. The HygroMatik DDS humidifies using condensate-free saturated steam and offers shortest possible humidification distances for space-saving installation in e.g. laboratories, clean rooms, hospitals, pharmaceutical, chemical and food industry.

In most applications, the HygroMatik DDS variant C (stainless steel grey cast iron) meets the requirements for optimum integration into the overall system. Hygromatik DDS variant A (100% stainless steel) is suitable for applications with increased hygiene requirements. In this compact 4-in-1 system, all steam-conducting components are made of stainless steel 1.4401 and thus also meet increased requirements for corrosion resistance in pure steam operation.

Depending on the project requirements, the DDS is individually configured and confectioned. The compact dimensions and the low weight enable quick and easy installation - even in difficult installation conditions.

Product description

Replaceable strainer

The high-quality stainless steel strainer protects the control valve and the steam trap from contamination from the steam network. The internal fine mesh strainer can be easily cleaned or replaced if necessary.

High-performance steam dryer.

The stainless steel steam dryer separates the condensate from the steam using a spiral-shaped control system.

Reliable start-up protection.

The start-up safety feature activates humidification only after a certain operating temperature has been reached. This effectively prevents condensate from the steam network from entering the air-conditioning duct.

High-performance condensate drain.

The robust, tight-closing ball float steam trap drains off the condensate. Due to the fast reacting principle and the high capacity, even larger quantities of condensate can be safely discharged, e.g. when starting up the system. The closed system prevents steam losses.

Stainless steel steam lances with integrated heating piping.

The HygroMatik pressure steam system DDS is equipped with a steam lance heating piping. Therefore, an additional sheathing is not necessary for efficient humidification.

The steam lances made of high-quality stainless steel have a low net weight, are particularly durable and quickly assembled. The low-noise steam nozzles draw steam centrally from the core stream, the driest area of the steam lance. The alignment of the nozzles against the air flow ensures fast distribution and a short humidification distance.

The internal, self-contained steam lance heating system is located at the lowest point of the steam lance. This allows any condensate to be evaporated again immediately. The lightweight and easy to maintain thermal steam trap drains condensate from the heating system. The heating system is fed directly from the steam dryer.

Optimum control of steam quantity.

The bus-capable actuator ensures optimum automatic control through direct connection – without adapter. The special HygroMatik control valve controls the steam quantity with equal-percentage characteristic curve. This enables particularly precise control in the lower control range and at the same time fast adaptation to high humidity requirements in the upper control range.

Optional accessories.

The recommended optional DDS shut-off valve ensures that, if required, the steam flow can be 100% interrupted for any duration, independent of the control valve.

The DDS manometer for pressure indication allows the current operating pressure to be checked.

Applications

Production and manufacturing processes

Print and paper.

In the print and paper industry, regulating the air humidity is necessary to ensure high-quality goods of materials and processes, as they both react strongly to humidity level changes.

Wood processing.

Since timber is a natural raw material which absorbs and emits moisture in accordance with its surroundings, indoor air humidity levels can significantly affect the use and production process of wood.

Automotive and aerospace.

In the automotive and aerospace industries, it can be challenging to maintain and control stable temperatures, especially during the production process e.g. in the foundry, painting line, and machinery room.

Electronics and high-tech manufacturing industry.

Electrostatic discharge (ESD) is more likely to happen if the air is too dry (less than 45% relative humidity). With the correct humidity level, costly damage to sensitive components or disruption to production processes can be prevented.

Air humidification in electronics and high-tech manufacturing environments

Laboratories and clean rooms.

Temperature and relative humidity plays a significant role in laboratories and clean rooms as they require stable, controllable atmospheric conditions in order to achieve comparable and consistent work results.

Food and luxury food industry.

Quality and freshness in food production can only be achieved through optimum air humidity. The correct moisture levels can stop foods from drying out and losing weight. At the same time, the ideal humidification encourages the ripening process of certain foods.

Air humidification in the food and beverage industry

Public buildings and offices

Museums and galleries.

Air humidification is vital in museums and galleries as they often house invaluable artefacts which require a regulated and consistent indoor climate to avoid damage.

Hospitals and doctors’ surgeries.

As the treatment and recovery of patients is the main focus in hospitals and doctors’ surgeries, a healthy environment plays a critical role in the quality of services provided by a medical facility.

Cruise ships and offshore.

Cruise ships require a vast amount of cooling performance for air-conditioning. Adiabatic cooling systems are an efficient and cost-effective solution. Regulated air humidity creates a pleasant, healthy environment on board.
