Intended Use
The Type 1500 furnaces are general laboratory and heat
treating furnace. For optimum element life, it is suggested
that this furnace be used for applications requiring
temperatures from 212°F (100°C) to 2192°F (1200°C). For
maximum element life, it is recommended to operate the
furnace at temperatures from 212°F (100°C) to 1950°F
(1066°C) for continuous use, or temperatures from
1950°F (1066°C) to 2192°F (1200°C) for intermittent use.
Continuous use is operating the furnace for more than 3
hours and intermittent use is operating the furnace for
less than 3 hours.
The unit consists of: 1) heating chamber, 2) a digital
controller and 3) a door interlock relay for user safety.
General Usage
Do not use this product for anything other than its intended
usage.
Principles of Operation
The furnace chamber is heated by four electric resistance
heaters which are embedded in a refractory material. The
chamber is insulated with ceramic fiber insulation. For
safety, a door switch is incorporated to remove power
from heating elements when door is opened. The furnace
chamber is supported by the control section which also
houses the electrical connections.
