1.General Description
Read thismanualcarefullybeforeoperationtopreventdamageofthe
machine orpersonalinjuries.
STM-Wserieswaterheaterareused toheat up the mouldand maintain
temperature,althoughtheycan be used inothersimilarapplications. High
temperaturewaterfromthe mouldisreturnedtothecoolingtankand cooled by
eitherindirect cooling(Forhightemperaturemodels)ordirect cooling(for
standardmodels). It isthenpressurisedbythehigh-pressurepump, sent tothe
heatingtankandfinallytothe mouldwithaconstant temperature.The
HANYOUNG temperaturecontrollercanmaintainan accuracyof 1.
