Presentation of the ’ company
STPL company activity and thin sheet metal treatment and coating of metals. Notably, it consists of a workshop of painting and related utilities (boiler water hot, compressor and air dryer, vacuum systems).
In the company of 40 employees, more than 10% of the costs are related to energy. With powers requested variable and sometimes very important, the METAL EE audit issues were double: reduce consumption energy and better control consumption peaks.
The audit resulted in different avenues for improvement officer characterizing, for each, the amount of investment and gross return times (TRI).
Action such as establishing a buffer on the compressed air system or the installation of a battery of capacitors in electrical departures head factory can be programmed with some sort of about 1 year. In other cases, simple optimizations of the process will allow these savings:
-More precise adjustments of the extractions of the paint line flow
-More complete closure of the drying tunnel
Finally, more substantial reflections can be conducted to review the Organization of work and deploy production in 2 teams rather than operation from 10: 00 daily. Time of temperature rise and maintenance of ventilation after the heating is turned off in will then be reduced.
