loxone server

Save 20 - 30% in energy costs through this intelligent building management system and control everything form everywhere without a cloud. From  apartment to industrial plant everything is possible.

Clarico-3 Columans Style 1


Produce heat & power in-house with a highly efficient turbine operated CHP-system. Safe 60 to 70% in CO2 emissions. Increase independence from public grid.

Clarico-3 Columans Style 1


Produce hydrogen from solar power and store it for the winter time to use it as fuel for your CHP-System, fuel cell or hydrogen heating device.

Clarico-3 Columans Style 1


Hot salt batteries are 100% recyclable, operate between -20° and +60° C, are lighter and smaller then Li-ion batteries and can not explode. Design life span 20 years, no degradation.

Clarico-3 Columans Style 1


Victron-Energy hybrid inverters are proofen systems for parallel- and off-grid use. PV system, genset, CHP-system and the grid. Switches in 1 Millisecond from grid to off-grid operation. 

Clarico-3 Columans Style 1


Capstone turbines for residential and industrial use. Reliable, durable with low maintenance costs. 8'000h maintenance interval. 65kWe power plus 150kWt heat output.

Clarico-3 Columans Style 1


Encapsulated latent material to boost your heat or cold storage capacity in the buffer by factor 2. Store more excess solar energy in the form of heat with less space.

our Products win awards

"Chaque fois que je parle de la protection de l'environnement à des chefs d'État ou des fonctionnaires, ils me disent que c'est trop cher. Ce label est un message fort pour eux : Les solutions existent et représentent la plus grande opportunité de marché de notre siècle, une opportunité qu'on ne peut pas manquer".

- Bertrand Piccard   


"Efficient Solution"

The Solar Impulse Foundation of Betrand Piccard awarded EnerTwin as "Efficient Solution".

This award has been given to EnerTwin because it is a CHP-System which saves substantial CO2 emissions but at the same time it is economically advantageous.
