These models have a maximum operating temperature of 1700°C and 1800°C. Models UAF 17/4 and 18/5 are bench mounted, whilst all other models are floor standing with lockable wheels as an optional extra.

Ultra-high purity alumina low thermal mass insulation and vertically suspended Kanthal Super heating elements, which radiate heat directly onto the workpiece, provide rapid heating and cooling and low running costs. These models offer advanced chamber construction with modular roof system and removable hearth.

The insulated door opens upwards and outwards, keeping the hot face insulation away from the operator. An electrically operated door is standard on the UAF 17/27 and UAF 18/27 models. A key switch is provided to prevent unauthorised opening.

A door switch isolates power from the heating elements whenever the door is opened for maximum operator safety.

Overtemperature protection is fitted as standard.
