Lessons learned |
|
|
Initiative |
Merl rates the use of renewable energies very high. The solar process heat plant helps to make the working processes even more environmentally friendly. A further goal of the company is to reduce energy costs permanently. For Merl it was important to cover a part of its energy demand by the solar process heat installation and reach a partially independency from increasing energy prices.

Integration methodology |
|
|
Crucial Interfaces |
For the realisation of this solar process heat plant the positive decision on the 30-%-grant was fundamentally decisive.
|
|
Construction / Commissioning |
The site logistic with the production plant in full operation requires sure instinct and a good
organisation.
The careful analyse of the heat demand and the heat flows within a company took approximately 1 year, after this the planning phase could be completed. The actual installation of the solar thermal plant and its commissioning could be realised in only 4 weeks.
For an optimal and smooth implementation of such an installation within a plant in full operation the encouragement of the client is indispensable, also the close cooperation between the technical management, the planers and the suppliers is particularly important.
