品牌：Gestra

中文名称：杰斯特拉 

品牌简介：

当在1902年由Gustav F. Gerdts成立时，工业时代才刚刚开始。该公司的目标有着明确的规定：

理顺蒸汽和能源管理，提高运行可靠性，实现高效率的冷凝水排出。通过不断的努力追求到如今实现这些目标，该公司已成为世界的蒸汽和冷凝水技术供应商之一。

产品范围包括蒸汽GESTRA疏水阀，疏水阀检测模块，止回阀，旋启式止回阀，控制阀，连续排污和间歇性放空阀，油探测器。在提供有效的电平控制，温度监测和控制TDS，我们的组件确保加压热水和蒸汽电厂的安全运行，还能防止生产中断。

当在1902年10月29由Gustav F. Gerdts成立时，工业时代才刚刚开始,Gestra公司成立。
