PDX.GOLD is proud to introduce the MK IV Terpinator, a botanical closed loop extraction system. The MK IV is AMSE certified and upholds only the best in quality, efficiency and safety.
PDX.GOLD only uses select local vendors to perform our custom machining and welding that is necessary to turn components into turnkey systems. The MK IV Terpenator closed loop design uses simple Alkane refrigerants, typically n-Butane, to accomplish extraction for the full range of plant terpenes from mono through tri-terpenes, and recovers the refrigerant for reuse. By using n-Butane, with its low boiling point at -31.5F, we make it possible to remove residual solvent to below controlled levels, while holding on to more of the lighter terpenes.
