Boiler controller

Sabien Technology Group, the Watford-based manufacturer and distributor of an intelligent boiler control system called the M2G, has obtained Underwriters Laboratories (UL) approval to sell its system in the US.

The certification will enable M2G to be sold in the US where it has already been piloted by its US distributor Greffen Systems at a number of prospective client sites over the past six months to see how it would perform in the different climatic regions of North America.

On the back of achieving UL approval, Greffen Systems placed an order with Sabien for £100,000.

The M2G is an intelligent control system that optimises the efficiency of an individual boiler. A unit attached to each boiler monitors the temperature of the water in the flow and return every 10 seconds and the information is recorded, along with the heat transfer rates at both first- and second-stage firings.

When a loading demand is made on the system, the M2G system automatically checks the latest data it has stored and decides whether it is more economical to retain a first-stage firing or to introduce a second-stage firing in the boiler.
