  • Unit Dimensions: 161.3”L x 61.0”W x 98.9”H

Facility requirements

  • Class 1 Division 1 area for the extractor with adequate ventilation to maintain 25% of the LEL of the solvent used
  • Unclassified area for the control panels
  • Source of chilled solvent: -40C at 1 gpm (nominal)
  • Chilled heat transfer fluid to maintain extractor temperature (3kW cooling capacity)
  • Provisions for output micelle flow and waste biomass discharge
  • 480VAC 3-phase electrical service at 14 Amps (not including cooling)
  • Facility wiring between control panels and the extractor to allow for maximum layout flexibility
  • Compressed air (100 psi, 0.6 cfm)
  • Appropriate spill containment in compliance with NFPA 30 ch. 17

General Operating Characteristics

  • Solvent minimum temperature: -40C
  • Solvent and slurry pump flow rate: 1-9 gpm
  • Input biomass flow rate: 1-5 lbs/min
  • Biomass requirements: dirt removed, dried, and chopped to ¼”-1” size
  • Screw speed: 1-5 rpm
  • Effective extraction duration: 5 minutes (1 rpm, 2 lb/min biomass, 1 gal/min solvent)
  • Waste biomass drip dry time (in upper chute): 4.5 minutes (at 1 rpm)

Handling requirements

  • Fork lift pockets: 40” long spaced 36” apart center to center
  • Weight 3400 lbs


  • Prewired for integration with the other Helderpad extraction subsystems including: biomass feeding, chilled solvent storage, separation, and filtering                                
  • Recirculation heat exchanger to maintain temperature in the extractor with chiller (3kW, -37C) to provide cooling for the recirculation heat exchanger. (Note: this is separate from a customer-provided solvent cooling system. When purchasing a Helderpad Solvent Chilling System, the chiller specified for that system also provides cooling for thE extractor recirculation circuit).
