BSN Thermprozesstechnik GmbH Modular Chamber Furnace System for Alumi

System Overview
Complete modular chamber furnace system for batch homogenising of aluminium extrusion billets, electrically heated with jet-heating, waste-heat recovery, and full automation. CE-certified (Machinery Directive 2006/42/EG).
Scope of supply:

1× Preheating furnace (BSN 1607) — electric, jet-heating
2× Holding furnaces (BSN 1608, 1609) — electric, forced air circulation
2× Heat-exchanger furnaces (BSN 1610, 1611) — unheated, forced air circulation
1× Charging machine (BSN 1612) — electric/hydraulic
12× Charging racks (BSN 1614)
Control cabinet with Siemens S7-1515F 2PN (Profinet) PLC and operator panel
Pusher thermocouples for direct billet temperature measurement

Key technical advantages:
Iodpoyuvq Tjfx Af Ejtd

Jet-heating for fast, uniform billet heating (typically 3–4× faster than conventional convection furnaces)
Integrated heat-exchanger furnaces for efficient waste-heat recovery — reduced energy consumption and operating costs
Overtemperature operation possible — shorter cycle times with direct billet temperature monitoring
Suitable for homogenisation and/or solution heat treatment / ageing
Modular design — suitable for new installations and retrofits of existing lines

Ideal for: Aluminium extrusion plants and casthouses seeking to optimise energy consumption, CO₂ footprint, and throughput.
