2. Chamber description

BINDER incubators BD and BF and drying and heating ovens ED, FD and FED are equipped with an

electronic PID-controller with digital display.

The incubators BD and BF indicate the temperature with an accuracy of a tenth of a degree.

The drying and heating ovens ED, FD and FED indicate the temperature with an accuracy of

one degree.

All chambers are heated electrically. Incubators BD and drying and heating ovens ED are ventilated nat-

urally. Incubators BF and drying and heating ovens FD and FED are ventilated by fan-assisted, forced-air

circulation.

The concept of air conduction guarantees high level of spatial and time-based temperature precision,

thanks to the direct and distributed air circulation into the interior. With BF, FD and FED, the fan supports

exact attainment and maintenance of the desired temperature accuracy.

The chambers are regularly equipped with an overtemperature safety device class 1 acc. to

DIN12880:2007 and with an overtemperature safety controller (overtemperature temperature safety de-

vice class 2 or class 3.1 acc. to DIN12880:2007), see chap. 7).

The inner chamber and the inside of the doors are made of stainless steel V2A (German material no.

1.4301, US equivalent AISI 304 and material no. 1.4016, US equivalent AISI 430). Drying and heating

ovens ED, FD and FED: When operating the chambers at temperatures above 150 °C / 302 °F, the im-

pact 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 com-

pletely 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 regularly (FED) or optionally equipped with an Ethernet interface for computer com-

munication, e.g. via the APT-COM™ 4 Multi Management Software (option, chap. 12.1) and with a USB

interface to read out the measured values in real time.

The models size 720 are equipped with

four castors. Both front castors can be locked by brakes.

Temperature ranges see technical data (chap. 16.4 - 16.8).
