Enclosures from Sarel are a key component in the control systems of the new waste water treatment reactors produced by process engineering company, Bio-Bubble.

Enclosures from Sarel, a brand of Schneider Electric, are a key component in the control systems of the new waste water treatment reactors produced by process engineering company, Bio-Bubble Each of the innovative sequence batch reactors, which treat waste water by aeration, has a two- or three-bay floor-standing sheet-steel enclosure assembled from products in Sarel's versatile and cost-effective Spacial 6000 range

The bays making up the enclosures measure 600mm wide x 400 mm deep x 1800mm high.

Each is equipped with a glazed outer door, enabling plant operators to check easily the status of the components mounted inside.

Extensive use is also made of Sarel's time- and space-saving modular mounting system for miniature circuit breakers and similar components.

Additional items are mounted on DIN-rail frames attached to the doors, and on perforated plates at the rear of each bay.

The multiple mounting options provided by Spacial 6000 series enclosures allow Bio-Bubble to save space on overall control system dimensions, without compromising the accessibility of the equipment within the enclosure.

"We chose Spacial 6000-series enclosures principally because of their versatility and value for money," said Paul Saxton, Director of Bio-Bubble.

"For example, the versions with glazed doors are far more competitively priced than alternatives we looked at, and the huge range of accessories available for the Spacial range made it easy for us to customise the enclosures to suit our application." Bio-Bubble's engineers were also impressed by the excellent finish, attractive appearance and durability of the enclosures, points which are of particular importance to the company's high-profile customers which include water supply companies and major international manufacturing concerns.

Equipment mounted within the enclosures varies according to the type of sequence batch reactor needed by the end user, but typically includes up to 14 motor starters with ratings up to 2.2kW, a number of larger star-delta starters, and two Modicon TSX Nano programmable controllers.

Protection functions are provided by Merlin Gerin circuit breakers.

Sequence batch reactor systems from Bio-Bubble are normally supplied as a complete package, with the control panels housed inside a temperature- and humidity-controlled GRP kiosk.

Nevertheless, to ensure correct operation of the control system even if the kiosk's environmental installations fail, the Spacial 6000 enclosures, which have an IP55 protection rating, are fitted with their own heaters and fans.

These products are again selected from Sarel's wide range of standard accessories.

"We've used Sarel enclosures not just on these systems, but in many other applications," said Saxton, "and we've always been delighted with their convenience, robust construction and attractive design.

We have also always had excellent support from Sarel, and the enclosures have the very important benefit of being readily available from our local stockist.

Given that Sarel products are also very attractively priced, there's simply no reason to choose anything else!".
