水槽浸入式加热器
浸入式加热用于加热和/或保持罐中的介质以降低所需温度下的粘度,以便于从介质中流出或泵出. 介质可以是冷凝水、沥青、化学品或收集在集水池中的任何污泥.
抽出式加热器(筒式)
除了传统的设计,加热器可以设计有可抽出的元件,这样可以在不排空水箱的情况下更换加热元件,以提供更快的周转时间. 这也称为在线更换.
我们花了很多心思改进筒式加热器设计,以缩短更换元件时的停机时间。 筒式加热器设计允许在线更换而无需排空水箱。 它有助于减少停机时间并最大限度地减少中断。 通过 DFINITI 的改进设计,我们进一步减少了 50% 以上的停机时间。 关键在于提供必要保护的密封类型。 它同时易于拆卸和访问,尤其是在更换加热器中心的元件时.
