HAL Extraction booth first to comply with UL 1389 –
Class I, Division 1 and 2, Group D
The use of essential oils from a variety of plant products in medical products, nutritional supplements and recreational products is rapidly increasing. As a result, manufacturers want to gain efficiencies while optimizing their growth. This puts a spotlight on safer production and a need to mitigate risk with the equipment used in the cultivation, processing and operations of plant oil extraction.
In this growing industry, often the extraction process itself creates hazardous conditions due to flammable solvents, including hydrocarbons, being released during processing. To increase safety, UL developed requirements and a certification program with input from industry for equipment used in the plant oil extraction process. These requirements allow manufacturers to design and manufacture new processing equipment according to a consistent set of criteria and thereby avoid delays in the building permit process.
Plant oil extraction equipment is evaluated to the requirements of UL 1389, Outline of Investigation for Plant Oil Extraction Equipment. The requirements of UL 1389 cover prefabricated plant oil extraction booths involving hazardous (classified) locations, along with plant oil extractors for use in hazardous (classified) locations. These prefabricated plant oil extraction booths are for fixed installation in accordance with ANSI/NFPA 70, National Electrical Code (NEC), the International Fire Code, and ANSI/NFPA 1, Fire Code, together with the manufacturer’s installation instructions.
Plant oil extraction booths from HAL Extraction Technology (Classic Series models: 85U, 120U, 150U, 180U, and 215U, Critical Flow Series models: 85C, 120C, 150C, 180C and 215C, and Production Series models: 170P, 265P and 355P) have achieved UL certification to UL 1389 involving hazardous locations: Class I, Division 1, Group D within the booth, and Class I, Division 2, Group D outside of the booth around openings for a distance of 3 feet in all directions.
