MERLIN Technology GmbH

Air humidification is not a luxury, it is a necessity!

With high pressure to higher productivity

MERLIN transforms water into a climate of success. Ambient atmospheric conditions have a substantial impact on basic material conditions. Hygroscopic materials, such as wood or paper, change dimensions and properties when the ambient air is too dry. Consequences are unpleasant and expensive.

Examples:

• undesired dimensioned change
• extra rework of damaged material
• additional uncalculated material costs
• production problems during heating season
• slower production rates
• unpredictable product quality
• higher electrostatic charge
• poor employee performance
• long time of staff away sick
• increased dust formation

The principle

Incoming water for high pressure systems is filtered hygienically clean drinking water. Additional water treatment is available with a softener, reverse osmosis and disinfection unit according to customers specifications. The water lubricated high pressure pump then feeds hoses up to 70 bars (1015PSI) and atomizes water at the nozzles. The flexible SPS-controller combined with the high quality humidity sensor keeps the relative humidity constant. With the optional PC-visualisation, you have the possibility to control the whole system from a remote workstation. The oil-free stainless steel high pressure pump has high industrial safety and long lifetime. Patented humidification units draw warm air from above the unit, providing fast evaporation. Use of humidification units without fans is possible with appropriate room dimensions.

SUPERIOR QUALITY AND PERFORMANCE

The high pressure air humidification unit uses filtered, clean drinking water. If needed, the water can also be softened, filtered via reverse osmosis and disinfected beforehand. Finally, the water is pressurized up to 70 bar by a pump and sent to humidifier modules, where MICRO DROP HIGH PERFORMANCE nozzles atomise the water. ALPHA uses a water-lubricated stainless steel high pressure pump as well as a touch-screen SPS-controller. You can use the controller to manage the whole water preparation process, starting with the water softening through to the RO filtering. One option is to use the OPC server to visualise the processes. As well as having a sensor that checks humidity and the safety hygrostat, the system also records temperature. The differential pressure indicator at the filters makes it easy to tell when maintenance is required. The MICRO DROP HIGH PERFORMANCE nozzles ensure that the water is micro-atomised optimally and consistently.

The new MERLIN® ORBIT WING® sets a milestone in high pressure duct humidification and can easily be integrated into each ventilation and air-conditioning system. It works on the basis of the high pressure atomizing principle and humidifies the air directly inside the duct with special MICRO-DROP atomizer nozzles. Wings integrated into the system provide defined swirling at the tear-off edge.

"The aerosols fly in a circle and fly further over a shorter distance. For generating 1 kg moisture merely 2,5 to 3 Watt of energy is used. The intelligent combination of step control and pressure control is also new and trend-setting.

Functional principle: The humidification system works with filtered and safe drinking water. The water passes through a prior water softening, optional a reverse osmosis respectively a disinfection unit according to customers specifications. The oil-free and self-lubricating hydraulic water pump then feeds hoses and pipes up to 70 bars (1015 PSI) and atomizes water at the special stainless steel MICRO-DROP nozzles in the ventilation duct. By the optimized PID regulation characteristics of the automatic PLC control an excessive humidification (condensation) is prevented.

Why humidity measurement?

Babies like it dry, but most materials don’t. The climatic conditions in the area around a part have a considerable influence on its consistency. Hygroscopic materials like wood, veneer, paper and paperboard containers change their form and material consistency when the ambient air is too dry.

The consequences are unpleasant and cost-intensive.

As a leading company in the area of humidity control, MERLIN has been involved for years in non-destructive moisture measurement technology for the materials wood, paper, building materials and biomass.

The principle ‚ultrasonic air humidification‘ creates ideal room and business climate conditions in an incredibly simple way:

• In a water container lamellas oscillate in a defined frequency range.
• Through this aerosols of merely 1μ are generated.
• These are released into the room air in a controlled way.
• Through them hygroscopic deficits are balanced.
• That way they create the individually perfect climate for tasks, offers and performances.
• Contra-Keim® and AquaDrain® guarantee highest hygienic standards.
