ACHE (Air-Cooled Heat Exchanger) belts have a special “Z” twist construction designed specifically for air-cooled heat exchangers. Because the ACHE drive has a vertical shaft, the ACHE belt is built with “Z” twist cords only. This gives the belt an upward direction of lateral movement which reduces excessive wear on the bottom side of the belt. The energy efficient ACHE synchronous belt performs at 98% operating efficiency for reduced energy consumption.


  • Special “Z” twist construction

  • Shrugs off shock loads by incorporating a non-aramid fiber tensile belt component that delivers strength and dimensional stability

  • Uniquely engineered RPP profile teeth are made of an advanced polymer compound which increases the strength and abrasion resistance of the teeth

  • Higher power ratings than conventional rubber synchronous belts

  • Backed by our Iron Clad Guarantee


  • Specifically designed for air-cooled heat exchangers.


  • 14M pitch in standard sizes
