These forced convection chamber furnaces are characterized by their good temperature uniformity. Due to the compact tabletop design, this series is very well suited for installation in laboratories or rooms with limited space.
Applications include preheating of components for shrink-fit processes, heat treatment of metals in air such as aging, stress relieving, soft annealing or tempering, and heat treatment of glass.
- Tmax 650 °C or 850 °C
- Horizontal air circulation with optimum distribution through stainless steel baffles
- Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
