Sample coolers

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.
