Maren ProPAK 2R350 Baler


When there’s tons of work to be done, turn to the Maren ProPAK 2R350 Two Ram Baler. This fully automatic 2 RAM baler is available with dual or triple motors to maximize performance and throughput while minimizing electrical consumption. A Large “Wide box” opening is great for handling a variety of recycled materials including scrap metals, post-industrial cardboard, plastic and more. The robust ram and door position transducers prevent shear jam while providing users automatic control and bale size and final bale finishing.

Maren’s SmartBale Intelligent baler control allows for password-protected saving of a complete set of parameters for each commodity to be baled. This eliminates cheat sheets, allowing an operator to reconfigure the baler during a material change by simply selecting the new material from a menu. In addition, with Maren’s Optional Smartbale Mobile Remote interface you can monitor and control the operation of your ProPak two ram baler with a portable full color touch screen.


ProPAK 2R350 Benefits

  • Large “Wide Box” (57” W x 80” L), clear opening with standard tongue and groove floor, ideal for both post-Industrial cardboard and scrap metals, while easily processing paper, fiber, plastic and other recyclables.
  • Interlocking plate steel construction distributes stresses away from welds to tabbed locking joints. : Chassis floor and sides constructed of seamless single sheet plate steel.
  • Replaceable “AR” hardened wear liners allow for limitless replacement of all chassis wear surfaces for years of reliable service.
  • Multi edge replaceable shear blades reduce cost by allowing blade rotation to gain additional new cutting edges before blade replacement. Extended progressive cutting profile shears material over a long distance effectively reducing shear jams.
  • 600-800 gallon floor mounted hydraulic oil reservoir shipped full of oil.
  • Clogged oil filter sensor, high oil temp sensor and low oil level sensors automatically protect your investment while notifying the operator attention is needed.
  • Robust ram and door position transducers allow automatic control of bale size, final bale finishing, shear jam prevention, wire placement and bale ejection.
  • Bale separation door facilitates instant material changes and virtually eliminates cross contamination between bales. The door’s transducer positioning allows up to 13” oversized bales to eject without jam, yet closely guides the bale to the tier for tight bales and reduced falloff.
  • All safety E-Stops and contactor resets monitored by a dual redundant safety relay system.


Baler Quick Specs


Dual 40hp, Dual 50hp or triple 40hp TEFC 3 Phase motors generate 80, 100 or 120 hp. Motors automatically stage start to reduce surge on electric service. During low production demand motors can be de-selected to reduce overall electrical consumption and throughput while maintaining 100% bale weights and shearing performance.


A simple but innovative hydraulic system allows the 2R330 to run faster and more efficiently while being more serviceable. highly efficient piston pumps rated for 6,100 psi run at only 4,200 psi ensuring less stress and long life. All pumps are mounted below tank level to eliminate start up cavitation and extend pump life.
