Installed units:

Below is an overview of installed plants to provide a better insight into function, market, and return of investment on the individual cases. The overview is not a static picture of price and function.

Type of Unit: Hot water, 10KV: 

Some of our first 10 KV units, installed at China GuoDian Corporation, in order to reduce energy consumption and harness surplus energy from their nearby wind turbine farm.


The park generated an average of 20% waste electricity, especially over the winter, when the wind turbines produced extra amounts of electricity due to the strong wind conditions. Thus, the company lost a lot of potential returns, by not being able to utilize the park's profits. GuoDian therefore invested in 5 of our thermal heating units; 3 units of 5.76 MW to heat a residential area of about 200,000 m2, as well as a further 2 sets of 4.32 MW, for 100,000 m2 of offices and public buildings.


The investment has been recouped after just 2 years.


Type of Unit: Oil, 6KV, 160-degrees:

Our 6KV unit at 160 degrees was installed at an industrial factory that used transformers in need of hot oil to dry insulation varnish etc.


The factory was located in a rural area without a natural gas pipeline nearby, and therefore only had the option of using electric heating of the oil.

As an alternative to using the expensive power during peak periods, the manufacturer invested in 2 sets of 8 MV systems that allowed them to run their heating at 1/3 of the price.

By using our devices that regulate and store power, the company has achieved huge savings.


The factory now maintains its current operation, the investment is recouped in less than 2 years


Type of Unit: 190-degrees, hot air: 

This system was installed by one of our own providers of packaging.

The factory had an epoxy powder coating line that used to run on natural gas, but at the given time, natural gas cost around DKK 4.9 per liter. cubic meters and produced 8600 Kcal.

Energy from off-peak periods, on the other hand, costs only 0.245 per KWH and produces 860 Kcal. Thus, the unit price for heat, with our plant, was cut down to just half.


As the factory is part of our own business, it is not possible to give the exact return of investment. However, the situation represents a typical case of a coating line using hot air. We have several similar projects and the return on investment depends a lot on which energy source is compared with and how many hours the factory is expected to be active per year.


Type of Unit: 80-degrees, hot air:

This client was a printing plant that produced disposable plastic for lunch packages on Chinese high-speed trains.


Previously, production was dependent on the electricity produced during peak periods and as the factory was only active during the day, the average electricity price was around 0.9 DKK/KWH.

After we installed our systems, that stores the power picked up at night, it was possible for the factory to pick up and utilize this cheap power for later use.

The system resulted a 0.3 DKK/KWH reduction of the price, and their operating costs are now only 1/3 of what they were before.


The project and got the return in just 9 months


Type of Unit: 60-degrees, hot air: 

This was an interesting project and one of our most successful, as the client's heat consumption was reduced by 74% after installing our product.

The factory produced latex-based balloons and used coal combustion to produce hot oil and to then again generate hot air.

For environmental reasons, the factory wanted to convert their coal combustion to a more sustainable production with less pollution.

We therefore abandoned the oil system and instead installed our system and focused on supplying hot air directly to the furnace.

After the restructuring, the factory's consumption has been reduced by 26%. Operating costs could not have been reduced like this, by, for example, switching to a natural gas supply or power from peak periods.
