The E (economy) range of Muffle furnaces have been designed without compromising any of the essential features associated with reliability and prolonged service life.  The ruggedly constructed steel frame will endure the trials of a workshop environment, yet is equally suited to a laboratory bench top.


Maximum temperature:                     1200C

Maximum continuous temperature:           1150C



The chamber is manufactured from a 98% Alumina material and is supported by lightweight low thermal mass ceramic brick. The bricks are machined to carry spiral elements of Kanthal A1 material. The chamber is equipped with a chimney for the removal of any undesirable gaseous / volatile contaminants.


For ashing applications, preheated air can be passed through the chamber and extracted through a large stainless steel chimney. (Optional extra)


In the interests of operator safety the door moves on a parallel link system up and over, keeping the hot face away from the operator, the door handle doubling as the external counterweight.


The entire cabinet is subjected to a seven-stage zinc phosphate anti corrosion treatment and then a durable epoxy powder coat is applied.




Standard instrumentation consists of a digital set, digital indicate dual display P.I.D. controller with power limiting facility and the capacity to auto tune P.I.D. values to the characteristics of your process.  This in turn operates a solid state, zero voltage-switching relays, causing minimal interference with other electronic equipment.

Type (k) thermocouple

A door switch isolates the elements in the interests of operator safety.
