The Acrobat 180 is now available for the underground/construction market for butt fusion of 63mm to 180mm HDPE pipe and fittings with a variety of pressure ratings. The product is for in-ditch work and tie-in fusions, and provides a cost-effective alternative to electrofusion, which requires the purchase of additional fittings. It functions in tight workspaces by removing the base and converting the carriage from four to three jaws. Two hydraulic power unit (HPU) options are available to provide fusion pressures up to 800 psi or 1,500 psi. Both HPUs allow the operator to pre-set the carriage, facer and heater pressures — eliminating repetitive adjustments between operations. Both HPUs offer a smart design so that both the heater and facer plug into the HPU, allowing the entire machine to draw power from only one receptacle. McElroy.
