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 in
to
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 chamber there is no risk for the user through the integration of the
chamber 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
The drying and heating ovens with forced convection and advanced program functions APT.line™ M are
specially developed precision warming chamber with high capacity. They are equipped with a multifunc-
tional microprocessor display controller with a digital display accurate to one-tenth of a degree. With their
comprehensive program control functions, they allow the high precision performance of temperature cy-
cles with fast heating-up phases.
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 at-
tainment and maintenance of the desired temperature accuracy.
The high-quality housing insulation ensures both a low noise mode of operation and a consistently low
housing temperature. The inner chamber, the pre-heating chamber and the interior side of the doors are
all made of stainless V2A (German material no. 1.4301, US equivalent AISI 304). When operating the
chamber at temperatures above 150 °C / 302 °F, the impact of the oxygen in the air may cause discolora-
tion 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. with the
APT-COM™ 4 Multi Management Software (option, chap. 11.1) For further options, see chap. 15.4.
The M 720
model is equipped with four castors. Both front castors can be easily locked via the attached
brakes.
At an ambient temperature of +18 °C up to +40 °C / 64.4 °F to 104 °F, you can operate the chamber in a
temperature range from 5 °C / 9 °F above ambient temperature up to 300 °C / 572 °F.
