Scientific Digital Imaging (SDI) has acquired Coalville-based Applied Thermal Control (ATC) for £1.2m.
ATC designs and manufactures precision re-circulating chillers, coolers and heat exchangers used to control the thermal environment within a wide variety of applications.
The Leicestershire-based company was founded in 1995 and has close ties with Loughborough University, employing 13 members of staff.
Ken Ford, chairman of SDI, said: “ATC represents another exciting step in our group growth strategy.
“ATC is a complementary fit to the group and provides potential areas for growth alongside a talented workforce.
“The acquisition is in line with our previously announced acquisition strategy and is expected to be earnings enhancing in its first full year of ownership.”
