Industrial & Laboratory Tabletop Furnaces
Pyradia's tabletop furnaces integrate quality components and superior workmanship for maximum performance in a variety of industrial or laboratory applications, at temperatures as high as 2300°F (1260°C). These units provide the toughness required for industrial applications with the versatility needed for precision lab work.
Applications
- General heat treatment
- Research & laboratory work
- Pyrolysis process
- Investment casting
- Jewellery
Product Features
Heavy Duty Construction: Rugged furnace design incorporates quality hardware to a heavy gauge casing for increased durability in all types of processes. Tabletop units are available in either a green enamel finish or oxidation resistant stainless steel.
Long Service Life & Ease of Maintenance: Specially designed grooved bricks optimize heat transfer and fully support the FeCrAl heating elements for maximum life expectancy. The open coil heating elements are easily accessible for maintenance.
Quality Insulation: Highest quality low-density refractory bricks used in the construction of the chamber assure maximum insulation while minimizing heating or cooling cycles.
Superior Heat Distribution: Special attention is given to the distribution of the heating elements to assure optimal temperature uniformity throughout the furnace.
Accurate Temperature Control: Tabletop furnaces are equipped with state of the art ramp to set point digital microprocessor temperature controller.
