25L Vacuum heat treatment lab used box-type furnace up to 1300℃
with Top exhaust valve
The FZK vacuum box-type furnace is externally sealed by a metal
mantle body fully, the furnace mantle is of a double-layer design,
the interlayer is of a water-cooled structure, and the surface
temperature is low. The resistance wire inside the furnace spirally
goes through a corundum tube, the heating elements are arranged
around, and the hearth is built of lightweight foam bricks. The
equipment can be pre-vacuumized to 30Pa, the air inlet system
flowmeter is designed at the bottom for control, and the waste gas
exhaust value is arranged on the top for control. The heat
treatment in the vacuum environment or atmosphere environment is
◆Working temperature: 1000℃ and 1200℃.
◆Intelligent preprogrammed temperature controller: Can edit, save
and transfer multiple programs.
◆The sealing method is double-layer furnace mantle water-cooled
external seal, and the surface temperature is low.
◆Lightweight foam brick heat insulation material, good thermal
impact resistance, low heat storage and high strength.
◆Surrounding heating, and good uniformity of the temperature field.
◆Over-temperature protective function: The power is off
automatically when the temperature exceeds the permissible set
◆Safety protection: The power is off automatically when the furnace
body leaks current.
➢Extra Options (Please indicate when placing the order. Contact us to get more
◆Furnace measuring system (oxygen content testing system, dew point
◆Atmosphere system (floater flowmeter, mass flowmeter)
◆Monitoring system (temperature recorder, touch screen remote
