OPTIMIZING ENERGY CONSUMPTION

The audit starts with a meeting with the management to review the company’s main technological processes and determine problem areas. We put forward a proposal on the scope of the audit after an on-site visit and expert involvement. The designing and installation of the metering system will take place after the acquisition and conciliation of data.  The results of reproducible measurements are evaluated together with the expert level. The audit report, conciliated with the experts and to be submitted to the management, includes project proposals on exploitable energy-saving opportunities and potential business parameters.  Our business proposals include the detailed investment requirements, maintenance costs and quantified benefits. 

Electric motors are relatively cheap, simple, low-maintenance machines, and they operate in an environmentally friendly way at the place of usage. It is also known that their operation efficiency is at the maximum at nominal capacity output.
However, there are a number of industrial applications (injection moulding machines, grinders, shredders, conveyors) where the electric engine load can be below 70% in a substantial part of the operation time.  Engine efficiency decreases to a great extent in such a range of operation. The intelligent ECU installed by us provides a solution to these problems.  The ECU continuously monitors the load and controls power consumption dynamically ensuring the realisation of possible energy saving. 

Based on our systematic engineering methods, examination of energy-saving possibilities begins at this point. At what voltage does the firm take up electric energy, who owns the transformer and in what condition is it? There could be up to a 30% difference of efficiency between a 30-year-old oil-cooled transformer and the low loss transformer installed by us.

Energy transformation means the conversion of one form of energy into another one. Our experts assess the quantity and type of primary and secondary energy in the technological processes used by the client. Based on the assessment and current energy supplies we determine the most cost-effective energy mix and make a proposal for the installation of the necessary equipment. When drawing up the proposal we pay particular attention to the investment return period as well as examination of the possibility of providing the needed energy from economical renewable energy sources.

Air conditioning systems used in old industrial halls may fulfil their technical tasks completely, but are they doing so in an environmentally friendly and energy-efficient way?  Following a full scale assessment carried out by our experts an audit report is drawn up concerning the efficiency of the existing HVAC equipment, and suggestions are made as to their cost-effective replacement.

The combined production of heat and electricity through cogeneration needs less primary energy than the separate production of these forms of energy. In the case of clients with significant electricity and process heat demand, our experts examine the possibility of the economical introduction of cogeneration considering the optimal size and number of equipment based on previous and future energy needs.
