Cogeneration, or Combined Heat and Power (CHP), describes the simultaneous production of heat and electrical energy with high efficiency in a single unit. We speak of high efficiency cogeneration when the overall efficiency of the installation exceeds 80%.
In the process of cogeneration using natural gas the source (natural gas) is supplied directly into internal combustion engine (or gas turbine), which in turn sets in motion the electrical generator to produce electrical energy. The waste heat which is the result of this process can be used to produce useful heat, which is most often applied to space and sanitary water heating, but can also be used in other processes. Waste heat is generated during engine and flue gas cooling.

The most important element in the cogeneration process is that energy is produced and used in the same place, so there is no loss in energy transfer. Cogeneration is the most efficient way of transforming primary energy into heat and power; in comparison with separate production of heat and power, cogeneration saves a substantial part of primary energy (eg. natural gas)

The overall efficiency and primary energy saving of cogeneration allows for reduced CO2 emissions into the atmosphere, thus mitigating environmental impacts.

We build in CHP devices manufactured by Kunttschar und Schluter.

Advantages and user benefits
Due to the fact that cogeneration produces heat and power simultaneously it is possible to save up to 38% of primary energy in comparison to separate production of heat and power.
Cogeneration devices have very high efficiency (fom 80% to 90%)
Reduces costs of energy supply for as much as 20% to 30%
Very reliable energy supply
Constant power supply, independent of an external network
Most effective use of heat and power due to local production, which reduces the loss of energy transfer to a minimum.
Environmental benefits
High savings of primary energy sources
Reduction of greenhouse gas (CO2) emissions
Cogeneration is considered an environment-friendly technology
Disadvantages of cogeneration
Requires constant output of power and heat to achieve the best possible efficiency of cogeneration
To achieve the best efficiency all the heat that is produced must be used up
Requires regular systematic maintenance
To achieve cost effectiveness a minimum requirement of 4000 working hours per year must be guaranteed


We are exclusive sales and service representatives for the world’s largest manufacturer of plastics injection moulding machines, HAITIAN.

Haitian Plastics Machinery Ltd has been solidifying its position as a global enterprise since 1994; with 30.000 units manufactured in 2010 they assumed first place in the field of plastic manufacturers, overtaking the German producer Engel. In recent years they have gained a firm foothold in Slovenia, with over 60 HAITIAN machines placed.

With mass production the HAITIAN is above all else the specialist in the field of production and application of plastics injection moulding machines.

In various product groups HAITIAN supplies standard hydraulic and power machines with clamping forces ranging from 600kN to 60.000kN. Using building components manufactured by recognized manufacturers and using progressive technologies, such as hydraulic pumps with auto tech motors induced drive, HAITIAN represents a technological high-end in its field. The machines are highly regarded for their efficiency, rapid response and quiet hydraulics, their modular design and user-friendly interface, CE accordance with European standards and last but not least their attractive prices.

These facts, combined with years of experience in injection moulding machines maintenance, have prompted us to take over the representation service for Slovenian and Austrian markets.

In cooperation with our clients we choose the optimal machinery, see to the purchase, logistics and installation of the device, including the trial run and user training. Among our post purchase activities we offer a 24/7 specialised and authorised service support.
