BD / ED / FD (E2) 03/2019 page 12/68
2. Chamber description
BINDER incubators BD and drying and heating ovens ED and FD are equipped with an electronic PID-
controller with digital display.
The incubators BD indicate the temperature with an accuracy of a tenth of a degree.
The drying and heating ovens ED and FD indicate the temperature with an accuracy of one
degree.
The chambers are heated electrically. Incubators BD and drying and heating ovens ED are ventilated
naturally. Drying and heating ovens FD are ventilated by fan-assisted, forced-air circulation.
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. With FD, 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 drying and heating
ovens ED and FD at temperatures above 150 °C / 302 °F, 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.
BINDER incubators BD and drying and heating ovens ED (option) are equipped with a serial interface RS
422 for computer communication, e.g. via the APT-COM™ 4 Multi Management Software (option, chap.
8.2). For further options, see chap. 12.7 to 12.9.
The models size 720 are equipped with
four castors. Both front castors can be locked by brakes.
Temperature range at an ambient temperature of +18 °C up to +40 °C / 64.4 °F to 104 °F.
• Incubators BD: 5 °C / 9 °F above room temperature up to 100 °C / 212 °F.
• Drying and heating ovens ED and FD: 5 °C / 9 °F above room temperature up to 300 °C / 572 °F.
