Generate energy efficiently
Identifying energy consumption as well as the actual demand in the various processes is crucial for energy-optimisation. Energy savings result from adjusting and controlling hot and cooling water temperatures, levels of compressed air or steam pressure and in turn an optimised operating method of ventilation, air condition or lighting systems.
Many companies provide high potentials on waste heat, which can be made accessible systematically. Since electric motors consume a major part of electricity, high cost savings can be achieved through adjustment to engine performance and optimised control of drives.
Case studies for energy saving projects
By optimising the steam process and utilising waste heat in a company of the chemical industry we were able to achieve considerable energy savings.
- energy costs savings: 40,000 € per year
- pay-back: 2 years
- return on investment: 50%
Within the scope of an upgrading concept for a meat producing company we identified a profitable conversion from steam to hot water within the heat generation process.
- energy costs savings: 80,000 € per year
- pay-back: 3,5 years
- return on investment: 25%
Our concept for a modernised cold water generation in an injection moulding company allowed the utilisation of free cooling to a large extent and therewith the application of cooling towers which are operated almost all-the-year alternatively to the chillers.
- energy costs savings: 95,000 € per year
- pay-back: 2,5 years
- return on investment: 38%
