Wood drying - LE

In order to bring the wood to the correct moisture condition for further use, huge heat volumes and special heat exchangers are required.
Since there is a lot of dirt in the air flow of the drying system, the choice fell on a particularly dirt-resistant and easy-to-clean roller pipe system with aligned pipe design. The fin spacing of 7 mm is very large for a heating coil, so that a certain particle size can easily pass through the heat exchanger. When the cleaning interval is reached, the fins are so robust with a thickness of 0.3mm that they can easily withstand cleaning with a high-pressure cleaner without deforming.
The heat exchanger frame is perforated all around for adaptation by the customer, whereby the slotted holes compensate for any tolerances, so that time-consuming re-drilling is no longer necessary.

Drying - LE/LK - Mälzerei/Malthouse

The drying of food requires a great deal of know-how. The same applies to the heat exchanger systems when it comes to the choice of materials, the construction and tube geometry to ensure the optimum transfer of heat. For the expansion and modernization of two new kilns at a large malthouse in Bremen/Germany, Roller supplied 12 heat exchangers (6 per kiln), each with a power output of approx. 1700 kW.  Total output: 20 MW.
