(ShareCast News) - Temporary power provider Aggreko said it has agreed to buy most of the assets owned by Canada's ICS Group Inc for £18m.Aggreko said the deal will not only establish a presence in the North American heater market, but would also provide a geographic footprint in cities such as Calgary and Winnipeg where it does not currently operate and complements many of Aggreko's key sectors including oil & gas, industrial and events."The acquisition of ICS enhances our temperature control business in North America and gives our customers an unparalleled range of equipment and service options. Temperature control products are used extensively in our target sectors and benefit our core business as they generally require associated power," said Aggreko chief executive Chris Weston.
