MGG Metran focussed on energy efficiency and sustainability when renovating the heating system. Instead of the outdated oil-fired boiler, a modern system that works entirely without fossil fuels now provides environmentally friendly heat. A further step towards energy independence.
In collaboration with a local installation company and the Austrian heat pump manufacturer IDM, the decision was made in favour of an air-driven heat pump, as there is no groundwater available at the site.
Until a few months ago, Metran in Kematen an der Ybbs was heated with a 170 kW oil boiler and two old air-water heat pumps. As the components were no longer state of the art and had recently become very prone to faults, the decision was made to replace the ageing systems. A suitable concept was developed in collaboration with the installation company Gebetsberger from Mauer near Amstetten and the Austrian heat pump manufacturer IDM. As there is no groundwater available at the site, the decision was made in favour of an air-driven heat pump with an output of 30 kW.
Waste heat and infrared for significantly lower energy consumption.
A central component of the modernised energy concept is the use of waste heat from compressors. This is utilised directly for heating via heat exchangers.
A central component of the modernised energy concept is the use of waste heat from compressors. This is utilised directly via heat exchangers to heat Hall 1 and fed into the water circulation system. This further reduces the electricity consumption of the heat pump, as it only needs to be switched on as a supplement. For additional heating of the workstations in the halls, the old electric fan heaters have been replaced by modern infrared heating panels, which provide locally focussed heat. Of course, the offices will also be heated with this new system in future. Surplus heat will be used to heat water. In summer, the heat pump will be used for cooling.
30 kW heat pump replaces 170 kW oil boiler. Photovoltaic electricity ensures self-sufficiency.
Managing Director Gunther Panowitz is delighted with a successful investment in the future. An investment that will pay for itself in five years.
„Thanks to the conversion and modernisation, we are now able to heat Hall 1 using significantly less energy“, reports Gunther Panowitz, Managing Director of MGG Metran. „And that also makes economic sense. Because we assume that the production costs will be amortised in around five years.“
The photovoltaic systems on all possible company roofs also ensure that the electricity requirements for heating, cooling or charging electric vehicles can be largely covered by internal power generation. In summer in particular, the photovoltaic surfaces supply a lot of energy, which is fed into the production facilities.
Efficiency, sustainability and economy combined.
„The new heat pump in combination with the utilisation of waste heat and the photovoltaic systems makes us efficient and environmentally friendly all year round. We have managed to reduce CO2 in a resource-saving way and achieve a high level of comfort despite reducing costs. A successful investment in the future!“ says a delighted Gunther Panowitz.
