The entire range of tube furnaces within the new E-Series 3-Zone Tube Furnaces by Carbolite use free radiating wire elements embedded within the insulation of the furnace body. This type of design is hugely helpful and flexible. The use of tube adapters the same furnace can be used with a variety of tube diameters.

The E-Series can be configured as horizontal or vertical, split and non-split.

A hinged furnace body on the EZS and EVZ models, split into two halves along its length, ensures that the exchange of work tubes is simpler. This also allows the furnace to be used with reactors or work tubes where end flanges would make insertion into a non-split furnace hard.

The division of the heated length into 3 zones ensures excellent uniformity. Each zone has its own controller and thermocouple.

An integral work tube is not includes in the E-Series range of tube furnaces, so one must be selected as an additional item. The type of application influences the work tube length, such as whether the application is for use with modified atmosphere or vacuum. Damage or contamination can be avoided with this use of a separate work tube.
