Professional laboratories throughout Australia, Asia and Africa have depended on Modutemp furnaces for many years. They are used for many differing heat-treatment processes, applied to a vast range of substances. This is why we produce such a wide variety of furnace types and sizes, yet are still called on to provide ‘specials’ to meet particular requirements.

Wire Wound Muffle Furnaces

These economical, benchtop muffle furnaces have one-piece ceramic chambers with the heating elements completely hidden. They are suitable for most heat-treatment processes at temperatures up to 1050°C(1922°F), or higher for brief periods.  For particular applications, these furnaces may also be equipped for adjustable airflow or controlled inert atmospheres, special controller requirements, over-temperature protection, remote monitoring etc. They are available in a range of sizes from 3 - 16 litres capacity.   PDF Specification Sheet

Wire Embedded Element Furnaces

These very efficient furnaces use wire elements, formed into coils and embedded in grooves in the chamber walls. This allows the heat energy to be radiated freely to all parts of the chamber and gives a maximum service temperature of 1250°C (2282°F) Available in a range of sizes from 12 - 50 litres, these furnaces provide an economical solution for many heat-treatment, ashing and general analytical purposes. When necessary, elements may be easily changed at low cost and without extensive dismantling. PDF Download

Wire Embedded Element Muffle Furnaces

These silicon carbide muffle chamber furnaces provide the ideal furnace conditions for gold cupellation work and many other processes where indirect heating and controlled airflow are required. The heat energy is provided by coiled wire elements, as in the WE type furnaces, but located in an outer chamber. The excellent thermal conductivity of silicon carbide provides a working chamber with almost no temperature variations. Controlled airflow passing through the chamber is pre-heated allowing full use of the available hearth area.

Molybdenum Disilicide High-Temperature Furnaces

These furnaces use carefully selected molybdenum disilicide heating elements and the highest quality ceramic fibre insulating materials. The results are furnaces able to achieve reliable, repeatable performance at temperatures up to 1800°C(3272°F). Simple to use, they can be found employed in a variety of testwork in Universities and Colleges as well as in commercial laboratories and ceramic production houses. Sizes range from 3 litre benchtop models to production models of over 1100 litres capacity. For details of the smaller models, click on "KSSPECsheet.pdf" below. For further details of larger, high temperature furnaces, click on "KS1MSPECsheet.pdf" below or go 'back to furnaces' and select 'Industrial Furnaces'. KSSPECsheet.pdf

Tube Furnaces

Tube furnaces enable a closely controlled, heated environment to be created for small scale test-work. The work-tube may be oriented horizontally, vertically or be fully adjustable to any angle. Work-tubes range in size from less than 25mm to over 150mm diameter and may be made from a number of ceramic materials, depending on the requirements. Maximum operating temperatures can be as low as 200°C or as high as 1800°C(3272°F). For some test-work, tube furnaces have one, two three or more heated and controlled zones. For a controlled atmosphere within the worktube, tube-end caps and an atmosphere gas control system is added. Please ask us about your application via the "Contact us" page of this website.

Bead-making Furnaces

Modutemp manufacture these compact, self-contained, semi-automated furnaces for the simplified and consistent production of fused samples for XRF or ICP analysis. The samples are fused in batches of up to six at a time, generally in around ten minutes. The close-tolerance temperature control and accurately-timed functions ensure that each sample is processed in consistent and repeatable conditions. "It's only the sample which varies!" An audible alarm sounds whenever operator action is required Available as four or six-place units for the standard 30ml capacity crucibles and the 40mm bead-moulds. Alternate cradles also available for up to five 'mouldibles'. Features of these furnaces include the ability to change the cradle configuration quickly without extensive dismantling. Simple programming allows the temperature, melting and shaking times to be pre-set for perfect repeatability while 'one button selection' of up to seven different pre-set fusion programs. e.g. Ore 1, Ore 2, Ore 3, Nickel, Iron, Tantalum etc. With units already installed in Australia, Indonesia, Papua New Guinea and China, these units are quickly replacing earlier generation equipment. Click on "SC142SPEC.pdf" below to access the full specification of these units. For lower throughput applications, a dedicated furnace is still preferred for bead-making, but automation is not necessary. The models SC32A (top-loading) and SC62A (front-loading) offer good capacity from very compact, benchtop units. SC142SPEC.pdf

Industrial Furnaces

For small industrial applications such as heat-treatment of many metals, the model WE630A is an economical basis which may be adapted to include fully programmed temperature profiles, protective atmospheres, remote monitoring, etc. For details of this furnace, click on "WE630ASPEC.pdf" below. For temperature critical applications or where the shape of the furnace may lead to lack of uniformity, a multi-zone control system may be required. The Ingot Furnace is one example. Another may be found under "Glass Furnaces". The 'top-hat' model KS11886 provides clear access to its hearth for loading and unloading with the entire furnace hood being raised by its single pillar elevator.

Special furnaces

Among the 'special' furnaces we have been asked to build in recent years, some have proved to be so adaptable that they become almost a standard. The model SC533 is such a case. This versatile, water-cooled design is powered by silicon carbide elements and offers a central core as the working chamber. Into this may be lowered a variety of retorts or other vessels. The control module houses all electrical switchgear, power supplies and the instruments. The Mercury Recovery Furnace allows safe removal and collection of mercury from gold amalgam as a simple automated process. The SCRH furnaces provide a twin-roller, rolling hearth within the heated chamber. This enables a sample quantity of any granular material to be heat-treated at temperatures up to 1600°C(2848°F) while contained within a pot which is continuously rotated. The clamshell furnace pictured at lower right was made to fit into an "Instron" test frame to allow material tensile and compressive tests to be carried out at elevated tamperatures. This same format can be used to heat tubular retorts or any fixed apparatus. For any furnace requirement not covered by these examples, please use the "contact us" page of this website to tell us about your application. Accurately controlled heat-treatment of alloy ingots up to 1M diameter x 4.5 metres long is easily accomplished in the pictured top-hat, multi-zone furnace. These can be made in sizes to suit any application. Model SCRH Mercury recovery furnace Model KS386 Clamshell Ingot Furnace

Glass furnaces
	Specialised furnaces for Art Glass casting have demanding control requirements to achieve quality work. The pictured unit allows over 1 cubic metre of volume with six control-zones managed by a Citect control system. This package uses a 3-D display to allow the operator total control. To allow large and heavy pieces to be safely loaded and unloaded, the hearth rolls on a railway.
