At 150\u2013400 bph and 1,500kg, it is a substantially larger machine than the rest of the HGS series, reflecting the scale of the 20-litre container format. The machine operates on 220V\/50Hz single-phase power and uses piston-type or cylinder hinge locking configurations.<\/p>\n<p style=\"margin-bottom:16px;\">The 20-litre water barrel is the globally standardised format for home and office water delivery services and water cooler dispensers. The HGS-350A is selected by regional water delivery operators, packaging companies supplying water brands, and producers entering the 20L market whose annual barrel volume does not yet justify the capital investment of a fully automatic JS-series barrel line. The 150\u2013400 bph output corresponds to approximately 1.2\u20133.2 million barrels per year at 8,000 operating hours \u2014 the typical scale for regional operations.<\/p>\n<p>For fully automatic 20L barrel production, the <a href=\"\/pt\/products\/\" style=\"color:#154360;\">EP-HGA.JS-2C366 fully automatic 2-cavity water barrel machine<\/a> or the <a href=\"\/pt\/products\/\" style=\"color:#154360;\">EP-HGA.J-2C366 edible oil barrel variant<\/a> are available.
