Ridgewood Electric Limited (1990) has been a respected electrical and electronic contractor to the tube and pipe industry since 1981. Prior to 1990 it was operated as Inductarn Inc. and changed its name in 1990 to reflect a change of ownership. Ridgewood acted as Canadian service agent for Inductron (Inductroguild) Ltd. of the UK until they were purchased by Thermatool Corp. in 1984. Subsequent to the purchase Ridgewood became service agent for Thermatool and Alpha. Ridgewood was appointed the exclusive sales and service agent of Thermatool and Alpha for Eastern Canada in 1992. Similar contracts developed with Thermatool Lemont and Thermatool Mill Systems in the years that followed. Ridgewood USA was incorporated in 1998 and was awarded the title of "Authorized Service and Distribution Agent" for Thermatool Corp in the United States. Over the years Ridgewood has established itself as a highly competent organization placing reliability and service as important keys to customer satisfaction. This has made Ridgewood a valued asset to a large number of tube and pipe producers in Canada, the United States and Mexico. Since 1984 Ridgewood has engineered, manufactured and installed its own line of mill drive systems. Currently, there are over twenty systems installed on mills within Canada. Several of these customers have multiple systems and some are planning the installation of further systems.
