A C1D1 room is a space classified Class I, Division 1 under Article 500 of the National Electrical Code (NFPA 70), meaning an ignitable vapor concentration is expected to be present under normal operating conditions. Its requirements are not a single checklist from a single authority — they are the sum of classified electrical installation,…
A hydrocarbon extraction machine uses a controlled solvent process to separate desirable oils, aromatic compounds, and other target constituents from botanical material. For commercial processors, the objective is not simply to produce an extract. It is to achieve a repeatable separation while protecting quality, controlling solvent movement, and preparing the resulting material for downstream refinement.…
Short path distillation equipment is vacuum separation equipment in which vapor travels only a few centimeters from a heated evaporation surface to a condenser, which lets heat-sensitive compounds be separated at temperatures far below their atmospheric boiling points. That one description covers a two-liter glass kit on a bench and a continuous stainless system running…
A wiped film system is a continuous thermal separation unit in which a rotor mechanically spreads feed into a thin, constantly renewed film on a heated, jacketed wall under deep vacuum, so volatile fractions evaporate in seconds rather than minutes. That short time on heat is the point: it lets you separate a heat-sensitive botanical…
BHO extraction equipment is the trade shorthand for closed-loop hydrocarbon extraction systems that run butane, propane, or a butane/propane blend as the solvent inside a sealed circuit and recover that solvent for reuse. What you are actually buying is four systems at once: a pressure system, a thermal system, a classified electrical system, and a…
How to Specify Closed Loop Extraction Systems: Pressure Ratings, Recovery Architecture, and the Documentation Package A closed loop extraction system is a sealed processing platform in which solvent moves from a storage vessel, through a material column packed with botanical material, into a collection base, and then back to storage through a recovery leg —…
C1D1 vs C1D2: Which Classification Your Process Actually Triggers Class I, Division 1 means an ignitable concentration of flammable vapor is expected during normal operation. Class I, Division 2 means it is expected only when something goes wrong — a rupture, a failed seal, or a ventilation failure. Division is a function of how often…
Solvent recovery is one of the most important stages in botanical post-processing. After extraction, the resulting solution contains both the desired botanical compounds and a significant volume of solvent. The purpose of recovery is to separate that solvent from the concentrated material so it can be collected, managed, and potentially reused in future production. At…
Butane extraction equipment is designed around a simple but important reality: solvent choice changes everything. In hydrocarbon extraction, butane behaves differently from propane, and those differences influence pressure, temperature management, recovery strategy, vessel design, safety planning, and the finished product a processor is trying to create. At MACH Technologies, we view solvent selection as a…
Cold ethanol extraction depends on one thing above all others: maintaining the right temperature at the right point in the process. When ethanol warms during transfer, staging, or contact with biomass, extraction behavior changes. The result can be less predictable crude, heavier wax pickup, slower filtration, and more pressure on downstream refinement. At MACH Technologies,…
