# Carbolite HRF Air Recirculating Oven

#### **The HRF air recirculation ovens come in two bench-mounted and two floor-standing models, capable of reaching 750°C.**

These models are equipped with powerful fans and horizontal air-guides. They are designed to provide rapid heating, high thermal transfer to the chamber contents, and high chamber uniformity. These designs often serve as the foundation for custom-designed chambers with non-standard sizes or control configurations. HRF ovens are frequently supplied with modifications to enable heat treatment within AMS 2750E Nadcap-compliant production environments.
