SLOOTWEG BPE SERIESWood fiber machine

Available in

Canada & USA, Europe and Oceania

The SLOOTWEG BPE Serie wood fiber machine is a compact and energy-efficient processing equipment designed to produce structurally resilient fiber from various wood by-products.

The patented extruding and refining technology apply high pressure to the raw material, generating heat above 100°C. This process produces and sanitizes wood fiber, ensuring compliance with RHP certification standards.

This innovative technology allows substrate producers to add various kinds of local wood by-products as complementary or alternative raw materials in their mixes.

Capacity: up to 12 m3 per hour EN (16 yd3 per hour)*

Raw materials: white softwood chips, forest residues, compost wood
