The energy audit of Gorenje identified significant savings potential in the compressed air station in Velenje.

With several production sites throughout Serbia, Univerzum aims to be the most modern brick producer in the region.

Two of Gorenje’s busiest production halls, for cooking appliances and washer-dryers, had outdated cooling systems.

Analyses performed as part of the energy audit of Gorenje by Resalta have shown that the process and space heating systems could be improved with the addition of a new cogeneration unit with a thermal input and electrical power of around 1 MW.

Oberon-H Ltd is one of the first food industry companies in Bulgaria for importing, packaging and trading pulses and honey. The product portfolio of the company includes a wide range of products including jams, sauces, preserves etc.

SŽ VIT, a member of the Slovenian railway group providing maintenance and technical services for trains and railway vehicles, hired Resalta to carry out a complete energy audit of its main facility in Ljubljana where its specialized electro-traction vehicles workshop is located.

Foodland is part of Atlantik Group and makes jams, ajvar, slatko and other spreads and preserves in its production facility in Kopaonik in the Serbia.

Plantaže AD, the largest winery in the region and one of the most famous, had very high energy costs. 

Resalta provided an immediate interim solution to enhance the functioning of the cooling system for technological purposes at the Melexis facility.

Following the realization of Resalta’s energy efficiency project in Livar’s Ivančna Gorica facilities, an energy audit showed that the Črnomelj site had an even bigger potential for savings.

The client’s compressed air was produced by an old and unreliable screw air compressor, treated with an adsorption air dryer. 

Its original two systems had an insufficient cooling capacity, were obsolete and had a low energy efficiency ratio, in addition to which they operated all year long and did not take advantage of the site’s free-cooling potential. 

Some of the older compressors are up to 40 years old and have an exceedingly poor energy efficiency ratio.

The client had no built-in comfort cooling in the production hall and used natural gas to heat the production hall.

The client wanted automatic data acquisition for the consumption of water, heat, electricity, compressed air and gas. 

Situation before the contract and client requirements Cremio is a dairy producer and manufacturer based in Bulgaria with a unique portfolio for the region of Eastern Europe.

The client was using biomass as an energy source but for a much smaller energy output. Due to a big increase in production the client’s energy requirements went up. 

The existing system includes three compressors, two of which have not been renovated since 1998. The system is highly unreliable with numerous fallouts and risks of failure.  

The client was facing high district heating costs and was planning an expansion of the production area that would further raise expenses. 

Client used old meters from 1950 with no communication system in place. In order to check energy consumption, manual control of 114 electricity meters had to be performed. 

Situation before the contract and client requirements Orgachim is one of the largest chemical companies in South Eastern Europe, producing specialty chemicals and coatings, and is based in Ruse, Bulgaria.

Gorenje’s facilities in Velenje were using natural gas cogeneration (CHP) units for heat energy supply with 880 kW of combined heat power and 654 kW of electrical power. 

Before reconstruction, the client had an over-dimensioned steam system, operating inefficiently with a very poor yield.

Gorenje had old and damaged luminaires and the light flux level did not conform to industry standards and norms. As a result, the lighting needed to be replaced. 

The client was using natural gas as an energy source to heat its facilities. The required heat was 1,703 MWh annually.

Resalta modernized cooling at the food processing plant.

Power factor compensation for Elixir Prahovo led to 20% savings on reactive energy consumption.
