• Non-ionizing radiation
Non-ionizing radiation is not intentionally produced, but released only for technical reasons by electrical
equipment (e.g. electric motors, power cables, solenoids). The machine has no permanent magnets. If
persons with active implants (e.g. pacemakers, defibrillators) keep a safe distance (distance of field
source to implant) of 30 cm, an influence of these implants can be excluded with high probability.
• Protection against touchable surfaces
Tested according to EN ISO 13732-1:2008.
• Floors
See operating manual chap. 3.4 for correct installation
• Cleaning
See operating manual chap. 9.2.
• Examinations
The chamber has been inspected by the “Deutsche Gesetzliche Unfallversicherung e.V. (DGUV)
(German Social Accident Insurance (DGUV)” (German Social Accident Insurance (DGUV), Testing
and Certification Body for Foodstuffs and Packaging Industry in DGUV Test) and bears the GS mark.
(Not valid for UL chambers)
UL chambers only: The chamber is certified by Underwriters Laboratories Inc.
®
according to the
standards UL 61010A-1, 1st Edition, UL 61010A-2-10, 1st Edition, CSA C22.2 No. 1010.1-92, IEC
1010-2-10.
2. Chamber 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.
The chambers 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 chambers are regularly equipped with a temperature safety device according to DIN12880:2007
(chap. 7).
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 chamber 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 chamber. The housing is RAL 7035 powder-coated. All corners
and edges are also completely coated.
All chamber functions are easy and comfortable to use thanks to their clear arrangement. Major features
are easy cleaning of all chamber parts and avoidance of undesired contamination.
The chambers are equipped with a serial interface RS 422 for computer communication, e.g. via the APT-
COM™ 4 Multi Management Software (option, chap. 8.1). For further options, see chap. 12.5.
The model FED 720 is equipped with
four castors. Both front castors can be locked by brakes.
The chamber can be operated in a temperature range of 5 °C / 9 °F above room temperature up to 300 °C
/ 572 °F.
