Successful application examples
in cooling flexibility
Two practical examples provide insights into how players along the value chain in the cooling sector work together and what obstacles still exist.
Participation is free of charge!
Registration is required – including agenda at:
Water-guided PCM heat storage for:
- Deep freezing
- Normal cooling
- Air conditioning
Cold applications
With our individual PCM storage solutions, we offer you the maximum possible flexibility when designing and planning your PCM storage system.
You can find common system variants in our planning notes.

PCM memory for:
- Room air conditioning
- Server room cooling
- Logistics cold stores
- Ventilation systems
Air application
Whether in a cold store, server room or for air conditioning, in times of expensive energy prices and increasingly important CO² savings, our air-guided PCM systems are ideally suited for integration into your system.

powerReducer – Increase your own power consumption:
Self-consumption set 3kW
- 3-phase energy meter
- Power electronics for connecting
to a 1-phase standard 3 kW heating element, such as a heating rod or eTherm C3
PV-Heat
with powerReducer + energieZähler
increase self-consumption:
The photothermal solar system for the use and storage of excess PV electricity in the form of heat.
- Stepless conversion of excess electricity to heat
- 3 phase measurement of the injected energy
- The storage process increases the proportion of self
- consumed energy increased – grid relief takes place
- Profitability can be increased
- Increase of own demand by use of the not in the household itself
- required energy in the form of heat
- Easy installation without disconnecting the main electrical line
