Improvement of battery holder

BONNEL TECHNOLOGIE has implemented one of technical improvements for its control units of the Sequetrol®starter, series, which are used for domestic sewage treatment plants with MBBR technology (moving bed biofilm reactor) or for WWTPs with the fixed bed. The back-up source for this control unit is an AA accumulator. A new cover which will be installed for every control unit of this model will fix the battery even better. Moreover, this cover can be mounted and dismounted very easily.
Among the versions of the Sequetrol®starter control unit you can select from a model with pressure measurement, current measurement and with a combination of both types of measurement.

Trimmer for setting of display contrast

Thanks to a new trimmer, BONNEL TECHNOLOGIE control units will have a better setting of display contrast. Like any other product, diplays also get older and wear off year by year. In case of control units which are exposed in the sewage treatment plants to extreme conditions, this process may be even quicker. The sun or extreme temperatures to which the device is exposed have a negative impact on the product ageing, too.

A trimmer will enable a service technician to correct and adjust the contrast of the control unit display on the spot at the given sewage treatment plant. For individual clients the contrast can be also customized and set as required.
As part of continuous quality improvement of its products, at the first stage BONNEL TECHNOLOGIE implemented this innovation for its product line BonBloc® compact.

The display, which provides the user with fundamental information about the control unit operation, will be thanks to a trimmer of higher degree of contrast and more legible. In general, trimmers are commonly used for the same purpose and effect in screens and displays, for instance in showcases.
