Our mission

To develop long term sustainable energy systems.

Therefore it is necessary that we need a new creative

way of thinking and acting.

In using what nature offers us without damaging flora

and fauna.

For significant reduction of CO2 emissions.

To avoid global warming and melting of the polar ice.

And to offer structural energy saving solutions for the

building market.

• PCM’s fits perfectly in architectural concepts and will add

significantly -up to 75%- of energy savings.

• PCM’s have the opportunity to become a standard in new

building architecture, but mainly in renovation projects.

• Because of a growing energy awareness and predicted exploding

costs of energy, many architects, engineers, building material and

air conditioning manufacturers announce to integrate energy

saving solutions in their projects and products.

• PCM’s can be compatible with various types of climate systems.

• It is estimated that in 2018 10% of all new and renovated

buildings will be PCM related.

An existing water cooled climate ceiling can be

equipped with PCM18-mats.

• Power reduction of the chiller possible up to 75%.

• Charging during night time low tariff hours.

• When the outside temperature during night time is low enough a dry cooler

can be used for charging.

• In this case a very energy efficient climate system with low maintenance

costs.

• Chiller is only needed for peak loads and/or cooling of the required amount

of fresh air.

PCM’s in hydraulic systems

PCM-solar collector

• Integration of a traditional vacuum tube solar collector and

PCM-storage.

• Easy mounting and safes interior space.

•Available hot water quantity ≈ 80 -150 L.

General system benefitsLess energy based on 2600 hours use of the building a year

(W-Europe):

Saving on electrical energy 9,3 kWh per net m² floor

surface for cooling.

Saving on natural gas 1,9 m³ per net floor surface for

heating (colder climate zones).

Reduction of CO2 emissions of 9 kg/m².

COP value of 250-500. With other words an energy saving

potential of more than 50%.

Reduction of electric power and installation equipment.

Installation costs normally the same as traditional.

Shift of eventually necessary additional energy to night

times at lower costs.

Examples of active PCM-systems

Active storage systems in combination with

chillers, heat pumps, cogeneration, solar energy etc.

Suitable for heat storage as well for cold storage.

Heating, air conditioning and industrial

refrigeration.

Optimum use of sustainable and waste energy sources.

Shifting possible to low tariff hours.

Reduce installed capacity with 30–75%.

Advantages of reduction of the power

connection!

• Easier application of sustainable energy sources,

such as:

Wind energy

Solar energy

Waste energy

But also:

Less maintenance

So lower operating costs
