Solartron Mobrey originally entered the industrial boiler control market in 1923 with a range of steam-operated equipment. Since that time the range has expanded to cover most aspects of control associated with the boiler house. Products range from electromechanical level devices to sophisticated electronic energy saving products that form a major step towards the fully automated boiler house.
Mobrey Vertical Air Break Controls are a comprehensive range of magnetically operated water level controls for steam boilers. They are designed to meet all the requirements for automatic on/off control of boiler feed pump, burner cutout, high and/or low level alarm or any combination of these.
The Solartron Mobrey Sequencing blowdown valve is designed to function as a manually operated combined water isolating valve and sequencing valve. It provides positive purging of the water connection, float chamber and steam connection of a boiler control.
Float operated level controls are inherently fail-safe and comply fully with the definitions for this parameter. Float controls can be made to comply with the definitions of high integrity and self monitoring by the addition of automatic checking equipment. This equipment is unique because it actually carries out a dynamic test on the level equipment, which is a more searching requirement than an electrical integrity test.
VABC heads are designed to fit into existing float chambers, and provide an economical method of updating boiler level controls to the latest models. Conversion heads are available for on/off controls and modulators. The Solartron Mobrey Controller is a single element electro-hydraulic control with an electronic feedback. The system comprises of a control unit float chamber, a feed line modulating valve and a control box. It is used for the throttle control with the modulating valve in the feed line.
Associated boiler products are also available; these include a range of conductive and capacitive probe controls for application on steam boilers. An automatic control check system has been designed to provide high integrity and self-monitoring to float operated controls. Flowmeters are available for steam, water and fuel flow measurement using orifice and low energy loss averaging pitot tube technology, non-intrusive meters are also available for liquid flow. Also available are self-calibrating, obscuration meters for smoke density.
Solartron Mobrey granted Dupleix Liquid Meters (DLM) exclusive distributorship rights for the Solatron Mobrey range of products in January 2001. DLM has seven branches countrywide.
