Diese K\u00fchlger\u00e4te-Familie stellt den neuesten Stand der Technik dar und erreicht h\u00f6chste Werte in Bezug auf Effizienz, Genauigkeit und Zuverl\u00e4ssigkeit.<\/p>\n<p>Bei PET-K\u00fchlger\u00e4ten wird die Drosselung der K\u00fchlleistung durch eine Drehzahl-Reduzierung des Motors erzielt, der den Kompressor antreibt. Die Rotationsgeschwindigkeit der Schraube wird je nach der momentanen thermischen Belastung, die abgebaut werden soll, reguliert. Hohe thermische Belastungen erfordern einen hohen K\u00fchlmitteldurchfluss, somit hohe Rotationsgeschwindigkeiten; eine geringe thermische Belastung erlaubt es hingegen, mit geringerer Geschwindigkeit zu arbeiten.<br \/>\nDurch Regulierung der Rotationsgeschwindigkeit des Motors wird die Stromaufnahme und somit der Energieverbrauch reduziert, im Gegensatz zu einer Maschine mit Schraubenkompressor ohne Frequenzumrichter, der bei konstanter Geschwindigkeit l\u00e4uft.<\/p>\n<p class=\" translation-block\"><strong>Unterscheidende Merkmale<\/strong><br>\n\u2022 Schraubenkompressor mit eingebautem Frequenzumrichter: (stabile Prozessbedingungen und Optimierung des Energieverbrauchs).<br>\n\u2022 Interne, vom Frequenzumrichter gesteuerte Pumpe: um konstante Dr\u00fccke im Wasserkreislauf bei \u00c4nderungen der Betriebsbedingungen sicherzustellen.<br>\n\u2022 Kondensatoren und Verdampfer: aus fest verl\u00f6teten und gro\u00dfz\u00fcgig bemessenen Edelstahlplatten, die die Effizienz des Kompressors erh\u00f6hen<br>\n\u2022 Elektronisches Expansionsventil (EEV) f\u00fcr eine bessere Kontrolle der Expansionsphase des K\u00fchlmittels und h\u00f6here Prozesskontrolle<br>\n\u2022 Stabilit\u00e4t der Prozesswassertemperatur (+\/- 0,1\u00b0C am Ausgang des Verdampfers).<\/p>","protected":false},"featured_media":6145,"template":"","tags":[],"acf":[],"yoast_head":"<title>PETChiller - Piovan Gruppe<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.piovan.com\/de\/product\/petchiller_piovan-china\/\" \/>\n<meta property=\"og:locale\" content=\"de_DE\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"PETChiller - PiovanGroup\" \/>\n<meta property=\"og:description\" content=\"This range of chillers adopts state-of-the-art cooling devices to reach the highest performance in terms of efficiency, accuracy and reliability.
