Northbridge Industrial services was set up as a shell to acquire industrial equipment rental businesses. Northbridge's chief executive Eric Hook used to run air conditioning and heating equipment rental business Andrews Sykes. He wants to build Northbridge into a significant industrial equipment rental and sales business. The first move was March 2006's purchase of Crestchic for £6.7m, which was financed by a share placing at 100p a share when Northbridge joined Aim. Crestchic designs, manufactures and rents load bank equipment. This is used to when diesel generators and gas turbines are installed or maintained. Further acquisitions have added to thos business.
