2. Chamber description

BINDER incubators with forced convection BF are equipped with an electronic PID-controller with digital
display. The temperature is indicated with an accuracy of a tenth of a degree.

The chambers are heated electrically and are ventilated by fan-assisted, forced-air circulation.

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 chambers are regularly equipped with a temperature safety device according to DIN12880:2007
(chap. 7).

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). 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. via the
communication software APT-COM™ 3 DataControlSystem (option, chap. 8.2). For further options, see
chap. 12.5.

The model BF 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
+100 °C 212 °F.

• Prior to connection and start-up, check the power supply voltage. Compare the values to the specified

data located on the chamber’s type plate (chamber front behind the door, bottom left-hand, chap. 1.4).

• When connecting, please observe the regulations specified by the local electricity supply company and

as well as the VDE directives (for Germany). We recommend the use of a residual current circuit
breaker.

Danger of incorrect power supply voltage.

Damage to the equipment.

 Check the power supply voltage before connection and start-up.

 Compare the power supply voltage with the data indicated on the type plate.

See also electrical data (chap.12.4).

To completely separate the chamber from the power supply, you must disconnect the power
plug. Install the chamber in a way that the power plug is easily accessible and can be easily
pulled in case of danger.

4.2 Connection to a suction plant (optional)

When directly connecting a suction plant the spatial temperature exactitude, the heating-up and the
recovering times and the maximum temperature will be negatively influenced. So no suction plant should
be directly connected to the exhaust duct.

Active suction from the chamber must only be effected together with extraneous air. Perforate
the connecting piece to the suction device or place an exhaust funnel at some distance to the
exhaust duct.

CAUTION

The exhaust duct will become hot during operation.

Danger of burning.

∅ Do NOT touch the exhaust duct during operation.

5. Start up

5.1 Turning on the chamber

Warming chambers may release odors in the first few days after commissioning. This is not a
quality defect. To reduce odors quickly we recommend heating up the chamber to its nominal
temperature for one day and in a well-ventilated location.

1. Insert the plug into an appropriate socket (chap. 4.1).

5.3 Air change

Opening the air flap in the exhaust duct serves to adjust the
air change.

Without connecting a suction plant:

• If the air flap is open and the fan is operating, fresh air

comes in via aeration gaps.

• If the air flap is completely open, the spatial temperature

accuracy can be negatively influenced.
