Description
The Bühnen HB 500 EHT is a heavy-duty pneumatic hot melt applicator engineered for very-high-temperature adhesive applications, particularly specialty polyamide hot melts requiring elevated processing temperatures.
Built around a proven, durable industrial design, the HB 500 EHT combines straightforward operation with digital temperature control for accurate management of demanding hot melt adhesives. Its rugged construction makes it particularly well suited for production environments where reliability, temperature capability, and adhesive output are critical.
The HB 500 EHT accommodates multiple adhesive formats, including adhesive slugs, bulk pellets, and pillows, providing flexibility across a range of industrial applications. When used with adhesive slugs, output can be significantly higher than when processing bulk-format adhesives.
Features
