NASHVILLE, Tenn. — Transtex, a developer of trailer aerodynamic solutions, announced the acquisition of a leading manufacturer of auxiliary power units.

Knowing that comfort is a major factor in driver retention, trucking companies have taken action through their choices of auxiliary power units and approach toward idle management.

Fleets are finding that auxiliary power units offer more than the potential to reduce fuel use — they also can limit wear on newer trucks’ emissions systems and help drivers comply with anti-idling laws.

Idle Free Systems has been acquired by Phillips & Temro Industries, a Minnesota-based supplier of heating and cooling equipment for heavy-duty trucks. Terms were not disclosed.
