MADISON — Idle Free Systems Inc., a Madison-based company, has been acquired by Eden Prairie, Minn.-based Phillips & Temro Industries.

Terms of the deal were not disclosed.

Phillips & Temro is a supplier of engineered thermal systems and controls for sectors such as heavy-duty trucks, off-highway, power generation, automotive and electric/hybrid vehicles. Founded in 2003, Idle Free Systems sells an auxiliary power unit, which takes electricity generated while a truck is moving and stores it in batteries for later use.

It allows drivers of long-haul trucks to use heat, air conditioning and electricity in their sleeper cabs without having to idle the vehicles’ engines.

In 2012, Idle Free doubled the size of its Watertown factory to 10,000 square feet.
