The chambers do not dispose of any measures of explosion protection.
DANGER
Explosion or implosion hazard.
Danger of poisoning.
Danger of death.
∅ Do NOT introduce any substance combustible or explosive at working temperature into
the chamber, in particular no energy sources such as batteries or lithium-ion batteries.
∅ NO explosive dust or air-solvent mixture in the inner chamber.
∅ Do NOT introduce any substance which could lead to release of toxic gases.
In case of foreseeable use of the device there is no risk for the user through the integration of the cham-
ber into systems or by special environmental or operating conditions in the sense of EN 61010-1:2010.
For this, the intended use of the chamber and all its connections must be observed.
2. Chamber description
BINDER incubators BD-S / BD-S-UL and drying and heating ovens ED-S / ED-S-UL and FD-S / FD-S-UL
are equipped with an electronic PID-controller with digital display.
The incubators BD-S / BD-S-UL indicate the temperature with an accuracy of a tenth of a
degree.
The drying and heating ovens ED-S / ED-S-UL and FD-S / FD-S-UL indicate the temperature
with an accuracy of one degree.
All chambers are heated electrically. Incubators BD-S / BD-S-UL and drying and heating ovens ED-S /
ED-S-UL are ventilated naturally. Drying and heating ovens FD-S / FD-S-UL 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 FD-S / FD-S-UL, 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 (ED-S / ED-S-UL, FD-S / FD-S-UL) or class 3.1(BD-S / BD-S-UL) acc. to DIN12880:2007),
see chap. 8.
The inner chamber and the inside of the doors are made of stainless steel V2A (German material no.
1.4016, US equivalent AISI 430). Drying and heating ovens ED-S / ED-S-UL and FD-S / FD-S-UL: When
operating the chambers 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.
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.
Temperature ranges see technical data (chap. 16.4).
