2. Unit description
BINDER drying and heating ovens FED are equipped with an electronic PID-controller with digital display.
The temperature is indicated with an accuracy of one degree.
BINDER drying and heating ovens with forced convection FED are heated electrically and are ventilated
by fan-assisted, forced-air circulation. They FED are equipped with a temperature safety device according
to DIN12880 (chap. 7).
The APT.line™ preheating chamber system guarantees high level of spatial and time-based temperature
precision, thanks to the direct and distributed air circulation into the interior. The fan supports exact
attainment and maintenance of the desired temperature accuracy.
The inner chamber, the pre-heating chamber and the inside of the doors are all made of stainless steel
V2A (German material no. 1.4301, US equivalent AISI 304). When operating the unit at temperatures
above 150 °C, the impact of the oxygen in the air may cause discoloration of the metallic surfaces
(yellowish-brown or blue) by natural oxidation processes. These colorations are harmless and will in no
way impair the function or quality of the unit. The housing is RAL 7035 powder-coated. All corners and
edges are also completely coated.
All unit functions are easy and comfortable to use thanks to their clear arrangement. Major features are
easy cleaning of all unit parts and avoidance of undesired contamination.
BINDER drying and heating ovens FED are equipped with a serial interface RS 422 for computer
communication, e.g. via the communication software APT-COM™ 3 DataControlSystem (option, chap.
8.1). For further options, see chap. 12.5.
The model FED 720 is equipped with
four castors. Bothfrontcastorscan be locked by brakes.
The unit can be operated in a temperature range of 5 °C / 9 °F above room temperature up to 300 °C /
572 °F.

When directly connecting a suction plant the spatial temperature exactitude, the heating-up and the
recovering times and the maximum temperature will be negatively influenced. So no suction plant should
be directly connected to the exhaust duct.
Active suction from the oven must only be performed together with extraneous air. Perforate
the connecting piece to the suction device or place an exhaust funnel at some distance to the
exhaust duct.
