Annealing Furnaces

Our annealing furnaces are designed specifically for changing the physical properties of samples.

We offer two different lines of annealing furnace, and within each line different models and options are available in order to meet your exact annealing requirements. The HRF air recirculating oven line contains two bench-mounted models (a 22 litre version and a 45 litre version) and two floor-standing models (a 112 litre version and a 324 litre version). The maximum temperature of each is 750°C, distributed across the chamber by powerful fans and horizontal air-guides for rapid heating and excellent temperature uniformity.

The GLO annealing furnace features CrFeAl heating elements in ceramic fibre insulation, providing a maximum temperature of 1100°C in the furnace’s vacuum tight chamber. There are three models in the GLO annealing furnace line: the standard GLO annealing furnace, the vertical VGLO, and the mobile GLO. Chamber sizes of 40, 75 and 120 litres are available. Please choose from our annealing furnace range below to view details.

Annealing Furnace Options

Available options for the HRF annealing oven include over temperature protection, digital controllers, multi-segment programmers, and data loggers. The HRF annealing oven is extremely adaptable and at request can supplied with the modifications necessary to make it AMS 2750E Nadcap compliant. We are also able to supply the oven with a custom designed non-standard chamber, should this be required.

The GLO annealing furnace has a vacuum tight chamber, and as such can be supplied with a vacuum pump to provide atmospheric control. The ability to reduce the Oxygen levels inside the oven by performing vacuum assisted Nitrogen cycling allows the sample to be annealed in an inert atmosphere – dramatically reducing the possibility of contamination. With the appropriate safety system in place, reactive gases can be used. A fast cooling system is also available.

In addition to annealing, the highly versatile GLO furnace is suitable for degassing, drying, glowing, hardening, pyrolysis, tempering, and thermal debinding prior to sintering.
