Universal energy saving (same fuel/energy)Calculating energy saving based on absolute values before and after modernisation for different energy sources/ fuel types.
Universal energy saving by fuel switchCalculating energy saving effects for measures considering fuel switch. Calculation is based on absolute values before and after modernisation. Different energy tariffs and efficiencies for energy conversation can result in significant savings. Example for profitable fuel switch is replacing electricity driven compressors by gas driven models.
Boiler replacement (same fuel)Boilers are major points of energy costs for heat and steam generation. Modern boilers can reach efficiencies higher than 95% whereas the average efficiency of boilers is around 70% in Russia. Replacement of boilers enhance efficiency, can reduce overcapacities and introduce management and control mechanism which all lead to reduced energy consumption.

Replacement of boilers enhance efficiency, can reduce overcapacities and introduce management and control mechanism which all lead to reduced energy consumption. Switching fuel type can be very effective due to different combustion efficiencies and energy tariffs.
Installation of economisers (heat recovery)Economisers recover residual heat of exhaust which is otherwise technical not usable. This recovered heat can be used to preheat water or air which will improve the efficiency of the subsequent equipment. Economisers are a separate module which can applied to boilers, burners etc.
Compressor replacement (reducing power)Exchanging compressors can result in energy savings by reducing capacity/power of the compressor. Reasons for lower power can be different efficiency of compressor types (screw or piston), modern technology and enhanced or management devices. Often old compressors don't produce the original amount of air due to abrasion of the material and hence have a longer operation time than new equipment.
Compressor replacement (increasing preformance)Performance of a compressor compares the power with the delivered air volume per second. Increased efficiency, modern technology and enhanced or management devices lead to improved performance. Often old compressors don't produce the original amount of air due to abrasion of the material and hence have a longer operation time than new equipment.
Replacement of motor (reducing power)Exchanging motors can result in energy savings by reducing oversized capacity/power.
Replacement of motor (increasing motor efficiency)Exchanging motors can result in energy savings by increasing efficiency of motor by improved technology.
Replacement of pump (reducing power)Modernisation of pumps can reduce power by eliminating oversized capacity, more efficient drives or improved technology
Replacement of pump (increasing performance)Improved technology, more efficient drives, leading to higher performance of ventilators. Performance of a pump compares the power with the pumped volume per minute.
Replacement of ventilator (reducing power)Modernisation of ventilator can reduce power by eliminating oversized capacity, more efficient drives or improved technology
Replacement of ventilator (increasing performance)Improved technology, more efficient drives, leading to higher performance of ventilators. Also the shape and design of the ventilator is object for efficiency improvements. Performance of a ventilator compares the power with the pumped volume per second.
Installation of Variable speed drivesVSD are devices to change the speed of motor's according to his load conditions. Speed reductions result through VSD's in a lower motor power. This reduction isgenerally indicated as average percentage. VSD's can be applied at motors used as pumps, drives, ventilators, conveyors or production lines.
Replacement of air condition (reducing power)Energy efficiency of air conditions are varying strongly between different types and models. Exchange of old air conditions with modern equipment will achieve energy savings through enhanced technology. Higher efficiency will generally lead to reduced power of conditioning unit.
Replacement of air condition (improved EER)The Energy Efficiency Ratio (EER) is an equipment parameter characterizing the effectiveness of the air condition. Energy efficiency of air conditions are varying strongly between different types and models. Exchange of old air conditions with modern equipment will achieve energy savings through enhanced technology. Higher efficiency will generally lead to reduced power of conditioning unit.
Improve lighting system (reducing power)Exchange of lams reduces the total installed capacity and hence lower energy consumption. Although one lamp has a small power the whole lighting system can amount to a significant energy consumption due to long operation time. Application of new models such as CFL, diodes or gas-discharge lamp can help to improve lighting efficiency.
Improve lighting system (increasing lighting area)Exchange of lams may increase the total installed power but improve the lighting conditions measured with the increase of area where the minimum illuminance is achieved. Although one lamp has a small power the whole lighting system can amount to a significant energy consumption due to long operation time. Application of new models such as CFL, diodes or gas-discharge lamp can help to improve lighting efficiency.
Exchange of transformerSince transformers are frequently in continuous operation, replacing transformers to improve efficiency can result in significant absolute savings. Experience showed that many transformers are oversized which lead to higher no-load losses. Adapting size of transformers and advanced technology can additional save energy.
Improvements on power transmissionPower transmission lines and other components on the transmission path have a certain resistance which lead to energy losses. Due to application of appropriate and modern equipment this resistance can be reduced which result in energy savings.
Replacement of trucksModern trucks have a reduced fuel consumption due improved efficiencies of engines and additional assitance systems. Especially the higher transport capacity can save fuel by reducing number of journeys.
Insulation of pipes and surfacesTemperature differences between inside and outside of the pipe can quickly exceed 100 degree. Hence good insulation is required for pipes like steam traps or surfaces at thermal equipment. Increasing insulation thickness or usage of better insulation material reduce energy losses.
Replacing windowsWindows and glazing are weak factors in buildings due to low insulation values. By exchanging old windows with double glazed insulated windows the heat transfer coefficient can be decreased which lead to energy savings in the heating system.
Advanced energy saving calculationEnergy efficiency comprised a high number of different measures. Many of them can be described with the improvement of the specific energy consumption which means the energy consumption per produced product e.g. 500 kWh energy consumption per ton of paper produced. This advanced calculation gives you the opportunity to calculate various options by entering the specific energy consumption before and after as well as the produced output. This calculation option gives you also the option to calculate energy savings while production amount increases.
