Nabertherm Forced Convection Chamber Furnaces – Tabletop Design (NAT Series)
The Nabertherm NAT Series is a “Made in Germany” compact, tabletop chamber oven available in 650 °C or 850 °C models. It features high-performance horizontal forced air circulation for outstanding temperature uniformity (as low as +/- 5 °C). Ideal for tempering, aging, or preheating.
The Nabertherm NAT series of forced convection chamber furnaces are “Made in Germany” and characterized by their outstanding temperature uniformity. Due to their compact tabletop design, these furnaces are perfectly suited for installation in laboratories or rooms with limited space. Moreover, their high-performance air circulation makes them ideal for complex heat treatment processes.
Applications include the preheating of components for shrink-fit processes, heat treatment of metals (such as aging, stress relieving, or tempering), and the heat treatment of glass. Consequently, this series is a versatile and reliable tool for any advanced material testing lab.
