Biasi Develops ActivA Unique Boiler Range Biasi UK has developed ActivA, a new range of high efficiency A rated condensing boilers boasting a unique heat exchanger. The launch of ActivA is further testimony to the company's commitment to strengthen its position in the UK domestic gas boiler market. At the heart of ActivA is a newly developed pre-mix condensing heat exchanger that is manufactured in a corrosion resistant, pressure moulded aluminium. Its sectional construction means it can be easily adjusted for different boiler outputs and its 'multipass' design ensures very low resistance for both combustion and water passage. This unique heat exchanger carries a five year guarantee. Designed to provide outstanding heating performance at an affordable price for almost all types of domestic properties, the compact range boasts some of the smallest boilers available - at just 700mm high x 400 wide and only 290mm deep - thereby allowing installation in cupboards.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as
