By integrating high-pressure air humidification, Svendborg Tryk avoided doubling its ventilation system.

Many companies can save hundreds of thousands Euros pr year by combining their ventilation systems with cooling by means of atomised water from high-pressure humidification.
This is the opinion of energy engineer René Agerholm who works as an energy advisor for EnergiMidt in Silkeborg.
“Far too many companies think along traditional lines when they need to remove excess heat from production, either by removing all excess heat using energy-demanding ventilation systems or by combining ventilation with traditional cooling systems.
In many cases, problems can be solved much cheaper and far more economically in terms of energy by combining demand-controlled ventilation with high-pressure humidification where excess heat is used to evaporate atomised water,” René Agerholm says.
This method is called adiabatic cooling and it facilitates considerable reductions in the consumption of energy for ventilation.
René Agerholm recently reviewed conditions at the Svendborg Tryk printing company where they had serious problems with their indoor climate because the ventilation system proved to be under-dimensioned following installation of new printing machines.

Large amounts of money and high levels of energy consumption are at stake according to a study of the Danish business sector's energy consumption, which was carried out in 2008 by Dansk Energi Analyse and Viegand & Maagøe for the Danish Energy Agency.
In 2008, the electricity consumption of the Danish business sector was 72.2 PJ (20,069 GWh). This is 60 % of Denmark’s total electricity consumption.
As part of the Elforsk programme, the Danish Energy Association completed a project in 2008 headed by the Danish Technological Institute. The resulting report states that adiabatic cooling (liquid evaporation) can cover a significant part of the need for cooling in Denmark.

ML System a/s in Denmark, is to ensure cooling and air humidity at Facebook's new data centre in Luleå, Sweden. The centre will become one of the world's most high-tech and energy efficient of its kind.
With more than 850 million users across the world, the internet based social network Facebook manages huge amounts of data. So far, this has been done at data centres in the USA,
Facebook’s new data centres will be among the world's most energy efficient of their kind so far. Two of them have already been established in the USA, while the third is being placed in Luleå in Sweden, where a Danish company will supply equipment for cooling and adding air humidity.
It is the company ML System in Ry , Denmark that has developed a highly energy-saving cooling technique with atomisation of water. Through the evaporation of the tiny water droplets, the room temperature is lowered, thus ensuring maximum performance from the servers. At the same time, the system counteracts static electricity.
– During the first phase, we are going to supply a system capable of distributing 8,300 litres of water per hour with a cooling effect of 5,650 kW. This is called evaporative cooling and can be achieved with an electricity consumption of just 40 kWh, the company's Managing Director, Marianne Jager, explains.
ML’s system for atomisation of water under high pressure was originally developed with a view to ensuring the right level of air humidity in nurseries, but since then, it has been used in e.g. supermarket fruit and vegetable sections as well as in a number of industries with a need to remove process heat or maintain a constant level of air humidity, e.g. the timber industry and the graphic industry.
ML System is to supply its system to Facebook in Luleå during the first phase of the building project. It is expected that shortly afterwards, that capacity will be expanded significantly during the second phase.
The system for Facebook is ML System's first installation of this type, but the company has great expectations for similar orders in the future. Over the next three years alone, many large data centres of a similar size are planned around the world.
ML System's agreement is with the Nordic installation group Bravida, who has been given total responsibility for the technical installations by main contractors NCC. ML System was chosen as supplier to Bravida (?) because the company has a reputation as being one of the most competent manufacturers of air humidification systems in the world. ML System is the only company that has been HACCP-certified according to ISO 22000 for ensuring and documenting hygiene-proof systems.
The first phase of Facebook's data centre in Luleå includes the construction of a building of 28,000 m2. The data centre will receive the LEED environmental certification. Bravida will have some 200 employees working on this job, which is expected to be completed by March 2013.
ML System in Ry, Denmark, was founded in 1987 and today employs some 50 people, of whom 10 are based at a branch in the USA, where the company sees great potential for growth. In the autumn of 2011, the company became part of the Swiss group Walter Meier AG, which is the largest in the world in the field of industrial air humidification with more than 1600 employees in more than 70 countries.
