• Compressed Air is an essential part of modern industry used by nearly every branch of production. In some sectors compressed air can take up to 20% (glass industries even 40%) of the electrical energy used. On average about 7% to 11% of the electrical energy in industry is used for compressed air. Due to its bad efficiency, compressed air is the most expensive form of energy in industry. Typical fields of application are: • Automatization: cylinders, engines, valves, conveyor belts, weaving • Active air: transport (e.g. bulk transport) • Process air: drying process, fermentation process, ventilation of sedimentation tanks • Vacuum: wrapping, drying, sucking, lifting, positioning The main advantages of compressed air are: availability, precision, downscaling, safety and the low weight of the tools used. Fields of application based on the pressure used: • Ultra-high pressure (>40bar): testing for leakages, power plants, oxygen bottles • High pressure (17bar-40bar): pipe pressure tests, blow molding of plastic components • Middle pressure (10bar – 17bar): heavy vehicles, special manufactures • Low pressure (<10bar): most industrial applications The compressors power lies about 45% above the value, needed for ideal theoretical compression.

• A solar thermal system transforms sunlight directly into heat. The thermal energy obtained from this transformation is used to heat the water necessary for the uses of the building as domestic hot water, for space heating or directly for use in the production cycle. As a renewable energy source, low-temperature solar thermal technology has enormous inutilised potential. Solar thermal can be supported by other heat sources and combined with storage systems for a guaranteedsupply. The integration of solar thermal systems in the calhours of industrial process can be done in the following ways: • Direct heating of a circulating fluid (e.g. supply water, return of closed circuits, air preheating). • In processes with low temperature requirements • As an additional source for preheating the feed water of steam boilers • Direct integration of solar heating in fossil fuel industrial steam boilers There are three groups of solar thermal technologies: • Solar air collectors, suitable for the food-processing industry to replace gas and oil-based drying; • Solar water systems, installed on rooftops of any industrial building, can be of two types: evacuated tube solar collectors and flat plate collectors; • Solar concentrators (CSP), suitable for electricity generation or high temperature steam for industrial processes.

• The need for cooling depends on two factors: • the heat load defined by the need for process cooling/storage • heat gains produced by multiple heat sources. The greatest heat gain for cold rooms is due to the hot air passing through open doors. This normally represents 30% of the total heat gain of a cold room. This measure does not reduce the cooling load, but allows to meet the cooling needs with reduced energy consumption. How to limit energy consumption? • Reduction of thermal loads inside warehouses • Reduce heat contributions through openings • Wall insulation • Implementation of free-cooling systems

• In industry it is essential to know the energy consumption of each of the production processes, to optimize it and be able to control any deviation that may occur. The automation of reading processes greatly simplifies operations and generates significant cost savings.

• In many systems the operating pressure is much higher than actually needed. Studies have shown that the pressure level can be reduced by up to 1 bar without influencing productivity. In many cases the pressure is reduced by regulators before reaching the users. This excess of unneeded pressure has to be provided and causes additional cost due to increased leakages Indicators • System pressure above 7 bar (most industrial appliances only need 7 bar)
