Sample coolers
Overview
Sample coolers provide a safer way to take representative boiler water samples from high-temperature, high-pressure systems without the sample flashing to steam. By cooling the sample before it reaches the operator or test point, they help preserve sample accuracy and reduce the risk associated with direct boiler water sampling. Sample temperature can typically be adjusted to around 25 °C, making manual analysis easier and more repeatable. That is useful when boiler water treatment decisions depend on reliable samples for conductivity, TDS or other routine checks. Spirax Sarco stainless steel sample coolers support boiler house users who need a practical route between live boiler conditions and meaningful water quality testing. They are typically chosen when safer manual verification of boiler water condition is still required alongside automatic instrumentation and control.
Related boiler water testing routes
Sample coolers support manual verification around a wider water-quality strategy. If the next step is routine measurement, add conductivity meters. When the sampling task exists to improve automatic control of dissolved solids, continue into TDS blowdown controls.
For broader instrumentation and feedwater decisions, return to boiler controls.
Continue your boiler water quality selection
Sample coolers usually support a broader water quality task rather than standing alone. The next route often depends on whether the user needs manual testing, automatic control or a wider boiler instrumentation package.
Pair safe sampling with water quality measurement
Use conductivity meters when sampled water quality also needs supporting instrumentation for routine conductivity measurement in the boiler house.
Connect sampling with automatic blowdown control
Review TDS blowdown controls when the reason for sampling is to improve dissolved solids control and reduce unnecessary boiler blowdown.
