水浴式气化器Water-bath vaporizer
用热水浴把低温液体加热气化，出力不随气温波动，是北方冬季与高负荷场合的补热主力。Water bath delivers stable output regardless of ambient — the winter trim heater.
产品概述Product overview
水浴式的价值就一条：它不看天气。空温式在 −20℃ 时掉到六成出力，水浴式仍是额定。北方 LNG 站、连续生产的工业用户、以及要求出口温度恒定的场合，水浴式不是备选而是必需。热源三选一：电加热（无锅炉的站点）、蒸汽（有蒸汽源的工厂）、热水（锅炉或余热），换热结构为壳管式或盘管浸没式。A water bath holds rating regardless of weather; heat can be electric, steam or hot water.
设计要点在温控与防冻：出口温度设闭环调节，水温低限联锁停泵，避免低温液体进壳程造成冻结；水箱做保温与补水，户外安装另加防冻排空。Closed-loop outlet temperature control with low-limit interlock and drain-down for outdoor installation.

核心优势Why this design
- 出力稳定：不受环境温度影响，冬季不降容。Stable output in winter.
- 三种热源可选：按现场能源条件定，不强制配电。Three heat sources to suit site energy.
- 与空温式串接：平时空温、峰时水浴，能耗最优。Series with ambient for lowest energy.
- 温控闭环：出口温度可设定并保持。Closed-loop temperature control.
