Sentry CWIS Cooling Water Isolation Skid

Part #
Configure Your CWIS

Poor quality plant service water and temperature variation can cause major problems with sample cooling. Plant service water chemical and physical purity, pressure and temperature are of particular importance for proper sample cooling. If the water contains any hardness, exposure to high temperatures in the sample coolers can result in scaling and a loss of cooling efficiency.

Chemical contaminants such as chlorides can cause stress corrosion cracking of stainless steel at elevated temperatures. Undissolved material in the water (e.g. silt, organic matter and corrosion products) can plug the sample cooler minimizing heat transfer capacity. The flow of cooling water may be insufficient due to low source pressure or excess pressure drop in the supply piping. Seasonal temperature variation of plant service water also affects sample temperature stability and analyzer readings. A Sentry CWIS cooling water isolation skid can solve these issues.


  • Eliminate problems associated with high silt, hardness, chlorides, and micro-biological aquatic life by isolating a closed cooling loop to your sample coolers or other equipment
  • Maximize sample cooler efficiency and life
  • Packaged system with numerous sizes and options including redundant heat exchangers or pumps

Cooling Water Skids

Eliminate sample cooler fouling & maximize sample cooler efficiency and life with cooling water skids.

Cooling skids can work in multiple ways. For example, the Sentry CWMS skid provides a way to cool samples that do not involve a mechanical chiller. There is a recirculating water pump that can control samples within ±1°F.

The Sentry CWIS skid, on the other hand, works by removing heat through a recirculating water loop. The loop with this system is cooled via a plate and a frame heat exchanger.

Both of these products maintain sample temperature for larger samples.

The Sentry team also has a team of established engineers ready to answer any questions you may have or help with technical support. Don't hesitate to contact us if you need assistance selecting the proper cooling water skid for your application.
