Year-round hall cooling for extrusion processes at Senoplast
At its Piesendorf site, Senoplast produces high-quality co-extruded semi-finished plastic products for industries such as automotive, caravans, sanitary and household appliances. Thermal extrusion produces high heat loads, further reinforced by ambient temperature and solar inputs. To ensure stable, energy-efficient indoor conditions despite these challenges, Senoplast opted for INFRANORM®’s Sustainable Hall Conditioning - an approach that was recognized with the 2023 Environmental Management Award for this specific project.

Project details
Senoplast has received a comprehensive Hall conditioning system developed, which takes into account all climate-relevant areas of the building. The five SHC systems deliver up to 112,000 m³/h of cooled fresh air and replace a conventional chiller with a cooling capacity of over 740 kW.
The two-stage adiabatic cooling ensures low supply air temperatures in summer, while process waste heat is directly used in winter. Thanks to efficient heat recovery, ventilation heat losses can be completely prevented.
Hall pressure control is a central component of the system: The production hall is operated at positive pressure, while the mill cellar is kept at negative pressure to reliably prevent dust from being carried over. Textile air outlets ensure draft-free and uniform air distribution.
The result: Constant temperatures, improved air quality, stable processes and a highly energy-efficient production plant.
“Employees benefit from a comfortable working environment with pleasant temperatures in both summer and winter. The high volume of fresh air significantly reduces plastic odours, even in winter, and the air feels fresh overall. The cooling system works very well in summer, and we consistently maintain the agreed parameters. As a result of the lower temperature levels, we have also been able to increase production output. ”
