Description of the equipment

Vacuum drying is used for special drying problems, for which conventional drying methods cannot offer a
solution due to physical limitations..
The VDL vacuum drying oven is approved for drying materials with organic solvents.
Ex classification
The chamber is equipped with an explosion proof inner chamber and additional measures for explosion
protection.
The Ex classification of the vacuum drying oven VDL (assembly) acc. to ATEX Directive 2014/34/EU is
II 2/3/- G IIB T3 Gb/Gc/- X
The description of explosion protection on the type plate determines the chamber's classification.
Detailed information on the Ex classification of the assembly and the individual devices can be found in
chap. 1.8.
The maximum possible surface temperature of the chamber interior is 160 °C / 320 °F.
Installation
The VDL vacuum drying oven may be installed in areas in which explosive atmospheres may occur on a
rare and temporary basis. The entire chamber with the exception of the power plug is classified in catego-
ry 3 in relation to the environment. The chamber plug (power plug) is unprotected, therefore the electrical
connection must be established outside a zone
Temperature class
The temperature class of the inner chamber acc. to EN 60079-0 is T3. The temperature class of the entire
chamber equals the temperature class of the inner chamber.
Controller
The chambers are equipped with a multifunctional microprocessor display controller with 2-channel tech-
nology for temperature and pressure. Temperature is indicated accurate to one-tenth of a degree, the
pressure inside the chamber accurate to one 1 mbar. Pressure is measured by a firmly installed pressure
sensor.
The chamber is regularly equipped with the MB2 display program controller. This efficient program con-
troller is equipped with a multitude of operating functions, in addition to recorder and alarm functions.
Programming of test cycles is easily accomplished via the modern MB2 touch screen controller and is
also possible directly with a computer via Intranet in connection with the APT-COM™ 4 Multi Manage-
ment Software (option, chap. 24.1).
The chamber comes equipped with an Ethernetserial interfacefor computer communication and with a
USB interface. In addition, the BINDER APT-COM™ 4 Multi Management Software permits networking
up to 100 chambers and connecting them to a PC for controlling and programming, as well as recording
and representing temperature and pressure data. For further options, see chap. 24.
