Sample cooler is a specialized cooling equipment for cooling and sampling high-temperature steam, boiler water, make-up water, and condensate in systems such as boilers, thermal networks, water treatment, and power plants. It is used for manual sampling or online water quality monitoring to ensure accurate testing and safe operation.
I. Core Features
Rapid Cooling: Cools high-temperature media (up to +300℃) to a safe sampling temperature of 30~40℃, suitable for water quality testing requirements.
Safety Protection: Prevent burns from high-temperature media and splashes, ensuring the safety of sample collectors.
Stable Flow Field: Constant flow regulation ensures accurate data from online water quality monitoring instruments.
Flash Vapor Prevention: Prevents flash vaporization during steam / high-temperature water sampling, ensuring the authenticity of the water sample.
Section 2: Working Principle
Typical shell-and-tube counterflow heat exchanger structure:
Shell side flows cooling water (recirculated water / tap water).
Pipe route for high-temperature pot water / steam / condensate.
Counter-current heat exchange of cold and hot mediums; the high-temperature medium is rapidly cooled and flows out from the sampling port, while the cooling water absorbs heat and is discharged.
III. Core Structural Components
Shell: Carbon Steel Powder Coated / Stainless Steel 304/316L
Cooling Coils: Stainless Steel 304/316L (Corrosion-resistant, excellent heat exchange)

V. Maintenance and Care Tips
Regularly inspect the coils for leaks or blockages to ensure smooth heat exchange.
Regularly clean scale from cooling water pipes and external deposits on coils.
Check the sampling valve's sealing integrity to prevent leaks.
Prolonged shutdown drain of cooling water to prevent freezing and cracking in winter.
Keep the sampling port clean to avoid water sample contamination.
