2. Chamber description
BINDER drying and heating ovens with forced convection and program functions FP are equipped with
the electronic program controller RD3 with digital display. This allows programming of temperature cycles
and an individual fan speed setting for each program section. The chamber provides almost unlimited
possibilities for adaptation to individual customer requirements based upon extensive programming
options and on the week program timer and real time clock of the controller.
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 fan speed is digitally adjustable
from 0 % to 100%.
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 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 influence of the oxygen in the air may cause coloration 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 completely coated.
The chambers are regularly equipped with a serial interface RS 422 for computer communication, e.g. via
the APT-COM™ 4 Multi Management Software (option, chap. 15.1). For further options, see chap. 19.5.
The model FP 720 is equipped with
four castors. Both front castors can be locked by brakes.
The chambers can be operated in a temperature range of 5 °C / 9 °F above ambient temperature up to
300 °C / 572 °F.
