The horizontal split tube furnace range HST (single zone) and HZS (three zone) uses free radiating wire elements embedded within the insulation of the furnace body. The benefit of this design is its flexibility; with the use of tube adapters the same furnace can be used with a variety of tube diameters. These furnaces comprise a furnace body which is hinged and split into two halves along its length. This makes exchange of work tubes easier and also enables the tube furnace to be used with reactors or work tubes where end flanges would make insertion into a non-split furnace difficult.

• Maximum operating temperature 1200 °C
• Carbolite Gero 301 controller, with single ramp to set-point & process timer
• Accepts worktubes with outer diameters up to 110 mm
• Horizontal furnace with a separate control module on a 2 m conduit
• Wire elements in high quality vacuum formed insulation ensure fast heat up, excellent temperature uniformity and short cool down times

Heated lengths: Single zone 200, 300, 400, 450, 600 or 900 mm (HST); 3-zone 600 or 900 mm (HZS)
End zone: Control is via back to back thermocouples (HST) or end zones of 150 mm each end (HZS)

The HZS three zone tube furnaces offer excellent uniformity which results from division of the heated length into three zones, each with its own controller and thermocouple.
