Carbolite EHA & EHC Compact Horizontal Tube Furnaces

The Carbolite EHA & EHC Compact Horizontal Tube Furnaces 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 tube furnace can be used with a variety of tube diameters.

The EHA are single zone furnaces and the EHC are three zone furnaces.

This range of tube furnaces does not include an integral work tube and one must be selected as an additional item. The work tube length is dependent on the application eg for use with modified atmosphere or vacuum. The use of a separate work tube has the advantage of protecting the heating elements from damage or contamination.

Standard features

• Heated lengths, 3-zone 450 and 600 mm (EHC)
• Accepts work tubes with outer diameters up to 60 mm
