■ 工作原理
■ 功能特性
DWXH系列低温冷却循环泵,是通过机械方式将液态媒介(酒精、乙二醇等简称冷媒)制冷,向自身工作区提供低温环境或者将冷媒通过强制循环输送给其他仪器的一种设备。可对接的设备如:旋转蒸发器,反应釜,超高速离心机等需要低温、恒温的设备设施,广泛应用于医药、电子、化工、大专院校等多领域的化学、生物、物理反应作业。
设备特点
1.采用可靠的风冷式全封闭压缩机组,制冷量大,速度快;
2.制冷机组专用继电器、保护器、电容等均为高品质器件;
3.采用数显控制器,人机界面友好;
4.可提供外循环,流量可调;
5.通用,可与多种仪器(旋转蒸发器、双层玻璃反应釜、高压反应釜、生物制药反应釜、发酵罐、冷冻干燥设备等)相配套;
6.适合在水源缺乏、水质、水压、水温不佳的环境及高温工作条件下使用,可向各类精密仪器设备提供有效的恒温保护。
8.所有型号均可根据要求(温度、流量、制冷量与容积)定制。。
