Our CHP installations are manufactured by a partner with quality assurance ISO 9001, which also has ISO 14001 environmental management system certification, and OHSAS18001 health and safety system certification, and of course our products are also CE certified.
It is important to work with a reliable company, all the more so that CHP installations require a considerable investment and are often operated 24/24/365 continuously.
The range unfolds in 2 energy carriers, on the one hand there are the diesel versions and on the other hand there are the gas versions, the latter can be offered in natural gas, biomass gas, butane gas and LPG.
The CHP installations are offered in a range from 6 KW to 500 KW, there is a selection of well-known brands in engines, including: Isuzu, Perkins, Cummings, Baudouin, MTU, etc., for the alternators you can choose between Mecalte , Leroy Somer, Stamford, giving you a guaranteed stable output with a good third harmonic, so you can connect sensitive equipment without any problem.
​As is known, 60 to 70% of the generated energy is lost in heat that is released to the environment, by equipping the generator with a heat recovery with a heat exchanger on the cooling water, and heat recovery on the exhaust, provided that an insulated casing can be used for maximum convert this “lost” energy into “heat” for various residential or industrial applications, resulting in significant energy savings and a contribution to the environment.
CHP installations are often used in greenhouse cultivation, where CO², electricity and heat are recovered.
In addition, there are fiscal and other support from the (regional) government, but also smaller applications, for example in combination with solar panels and storage batteries for residential applications, or for example for cooling installations, where a heating process is also in operation in addition to cooling.
Javac can take care of the entire installation, from installation and commissioning of the CHP, as well as the complete control to external components.
If you are interested in a CHP installation, we suggest sending you a brief description of your existing situation and the application you propose, so that we can make you an appropriate offer.
On our CHP page we present you some CHP installations in order of 12 to 80 KW, equipped with a gas engine, but other projects are also welcome, also for installations abroad.


General framework
When it comes to energy, electricity is the first thing that comes to mind. However, the vast majority of energy is not electricity, but heat.
Traditionally, the production of electricity and heat is done separately.
The joint generation of these 2 forms of energy by means of combined heat and power (CHP).
However, this offers a number of significant advantages, as described below.
​Heat and electricity are both forms of energy, but not equivalent.
For a good comparison, we take into account the convertibility of energy into another form of energy.
Please note, not all forms of energy are completely convertible into other forms of energy.
We use the terms “exergy” and “anergy” for this.
​Exergy is that part of the energy that can be completely converted into another form of energy; on the other hand, anergy is the part that is not (any longer) fully convertible into another form.
It should be clear that exergy has a greater value than anergy, so it is desirable that this exergy is used sparingly.
​Electricity is a completely convertible form of energy, for example from mechanical energy to heat, … and therefore consists of 100% exergy.
Heat, on the other hand, is a form of energy with a lower quality, which can no longer be completely converted into another form of energy.
Heat therefore contains anergy in addition to exergy, and the share of the anergy increases as the heat decreases.
Heat and electricity are often produced separately, i.e. each form of energy is generated by a separate installation.
Electricity, unlike heat, is easy to transport.
Production is therefore often done remotely, in large thermal power plants.
The electricity is then brought to the end user via the high-voltage grid.
Heat, on the other hand, is usually produced on site, using a water heater or boiler.
The energy of the fuel is converted into heat there via a combustion process.
This heat is usually demanded at a relatively low temperature.
This means that the energy from the fuel is converted into heat with a large proportion of energy.
In the light of the most efficient possible use of fuels (oil/gas), this is unfortunately a regrettable finding, as precious exergy is lost.

​The principle of CHP
Combined heat and power (CHP) is an energetic process that contributes to limiting exergy losses in heat production.
In this process, heat and electricity are produced in the same installation. Given the fact that heat is difficult to transport, this installation is located close to the heat consumer.
The high-quality heat that is released when the fuel is burned in the engine of the generator (power generator).
After this, the low-grade residual heat (the temperature of which can range from 80 °C to 500 °C) remains, and this is then used to meet the specific heat demand of a company, a hospital, .
​It can therefore be said that a CHP is a smart way to generate heat, with a much higher exegetical efficiency.
Heat is indeed the most important factor, and it is therefore essential that that heat is put to good use.
That is why a CHP is preferably dimensioned according to the heat demand.
The electricity generation is used to produce the heat at the desired temperature, thus ensuring less exergy loss and a more rational use of energy.
The principle of cogeneration can be further extended by also considering tri-generation.
In addition to electricity and heat, such a unit also produces cold.
An absorption cooler is used for this, i.e. the heat is used in such a machine to produce cold.
When the demand for heat decreases in the summer period, the CHP can still continue to run and use its heat usefully to meet the demand for cooling.

​The strengths of CHP
The big advantage of a CHP is therefore that with the joint generation of heat and electricity, the available energy is used much better.
As a result, co-generation requires less fuel than separate production of the same amount of heat/electricity.
It is known that the reserves of fossil fuels are limited, the message is to use them sparingly.
CHP is of course an interesting technology in this respect.
Most CHPs work on fossil fuels, but it is also possible to use renewable energy sources as fuel, just think of biomass or biogas.
Such an application offers a double advantage: not only is an environmentally friendly fuel used, but it is also used optimally.
Less fuel consumption also means that CO2 emissions and the emissions of other harmful substances (soot, NOX, SO2, CO) are reduced.
The listed substances occur in ever higher concentrations in air, water and soil.
Its impact on the environment, atmosphere and climate is considerable, just think of the greenhouse effect and the ozone problem.
The European Union’s climate policy has set three targets for 2020, known as the “20-20-20” targets.

These are:

  • 20% reduction in greenhouse gas emissions compared to 1990 levels;
  • 20% renewable energy production;
  • 20% improvement in energy efficiency.

A CHP installation can make a contribution here.
An increase in the number of CHPs will also ensure that electricity production shifts from central production to decentralized production.
This will lead, among other things, to a relatively strong reduction in losses in the high-voltage grid.
