The Hydessco, LLC HD (Heavy Duty) Spooler is a robust and reliable unit capable of accepting common wooden and steel spools up to Ø72” (sideboard flange) X 36” traverse.  The HD Spooler drive system consists of high speed/low torque hydraulic motor and chain-driven sprocket reduction.  The HD Spooler drive shaft is ported to accept a high-pressure swivel connection (up to 15ksi) for hookup to the fluid pump and capillary string.  The levelwind assembly on the HD Spooler is a chain-driven positioning system powered via hydraulic motor to keep tubing aligned with tubing being paid off and re-wrapped during retrieval.  The operator’s cabin controls regulate backpressure on the HD Spooler to prevent tubing from free-wheeling as it is injected into a well.
