Our customers value the solid, user-friendly technology and the high degree of automation. Grenzebach possesses the know-how of an internationally active equipment manufacturer, also encompassing consulting, engineering, and project management services - a real boon for the insulation materials industry.

Drying and handling equipment insulation materials

Drying and handling technology for a variety of building materials applications, such as acoustic ceiling tiles, are just as much part of the Grenzebach range as are special processing solutions for value-added products. We are well-versed in high performance lines with a special focus on efficiency and availability as well as the integration of already available equipment.

The building materials industry values Grenzebach's production technology since we are able to respond to individual requirements.

Drying equipment

Our product range includes single and multi-level driers for drying various building materials: longitudinally vented, transversely vented, with rollers or band screens, with energy saving systems. We also offer drying tests and extensive investigation of raw materials as well as of semi-finished and finished products in our laboratory and technical centre.

Handling equipment

We implement customer-specific product requirements. Various transport and conveyor systems are perfectly combined and adapted to the requirements of individual production processes at Grenzebach - everything from a single source. Our range of products: Feeder systems, conveyor systems, process technology like cutting, trimming or formatting, stacking, palletising and packaging systems.

Automation and control systems

Customized mechanical solutions combined with efficient control systems enable you to significantly improve the productivity and quality while retaining economic viability and functionality at the same time. Integrating existing or customer-supplied equipment and processes into safety systems, formulation and order management, as well as linking to customer's ERP systems are a matter of course.
