Delayed start & process timer function as
An economical furnace designed for light duty and general laboratory
work. Low thermal mass insulation & multiple semi-embedded, free
radiating wire wound elements in the chamber sides provide efficient
heating. Ventilation is via a top-mounted ceramic chimney, but if toxic or
corrosive fumes are likely, use of one of our
dedicated ashing furnaces or a retort should be
considered.
Options:
Over-temperature protection (recommended to protect valuable contents & for unattended operation).
Continuous operating temperature is 100°C below maximum temperature. Holding power is measured at continuous operating
temperature. External dimensions with door closed and include chimney.

●
A variety of retorts & modifications are available for working with modified
atmospheres.
“Universal” models are easily altered between single phase(220V), 3 phase+neutral (e.g. 380/220V) & delta (e.g. 220V) electrical supplies.
Continuous operating temperature is 100°C below maximum temp. Holding power is measured at the continuous operating temp.
