■ 工作原理
■ 功能特性
DWXH系列低溫冷卻循環泵,是通過機械方式將液態媒介(酒精、乙二醇等簡稱冷媒)制冷,向自身工作區提供低溫環境或者將冷媒通過強制循環輸送給其他儀器的一種設備。可對接的設備如:旋轉蒸發器,反應釜,超高速離心機等需要低溫、恒溫的設備設施,廣泛應用于醫藥、電子、化工、大專院校等多領域的化學、生物、物理反應作業。
設備特點
1.采用可靠的風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、電容等均為高品質器件;
3.采用數顯控制器,人機界面友好;
4.可提供外循環,流量可調;
5.通用,可與多種儀器(旋轉蒸發器、雙層玻璃反應釜、高壓反應釜、生物制藥反應釜、發酵罐、冷凍干燥設備等)相配套;
6.適合在水源缺乏、水質、水壓、水溫不佳的環境及高溫工作條件下使用,可向各類精密儀器設備提供有效的恒溫保護。
8.所有型號均可根據要求(溫度、流量、制冷量與容積)定制。。
