■ 工作原理
■ 功能特性
DWXH系列低溫冷卻循環(huán)泵,是通過機械方式將液態(tài)媒介(酒精、乙二醇等簡稱冷媒)制冷,向自身工作區(qū)提供低溫環(huán)境或者將冷媒通過強制循環(huán)輸送給其他儀器的一種設(shè)備。可對接的設(shè)備如:旋轉(zhuǎn)蒸發(fā)器,反應(yīng)釜,超高速離心機等需要低溫、恒溫的設(shè)備設(shè)施,廣泛應(yīng)用于醫(yī)藥、電子、化工、大專院校等多領(lǐng)域的化學(xué)、生物、物理反應(yīng)作業(yè)。
設(shè)備特點
1.采用可靠的風(fēng)冷式全封閉壓縮機組,制冷量大,速度快;
2.制冷機組專用繼電器、保護器、電容等均為高品質(zhì)器件;
3.采用數(shù)顯控制器,人機界面友好;
4.可提供外循環(huán),流量可調(diào);
5.通用,可與多種儀器(旋轉(zhuǎn)蒸發(fā)器、雙層玻璃反應(yīng)釜、高壓反應(yīng)釜、生物制藥反應(yīng)釜、發(fā)酵罐、冷凍干燥設(shè)備等)相配套;
6.適合在水源缺乏、水質(zhì)、水壓、水溫不佳的環(huán)境及高溫工作條件下使用,可向各類精密儀器設(shè)備提供有效的恒溫保護。
8.所有型號均可根據(jù)要求(溫度、流量、制冷量與容積)定制。。
