Sentry Sample Coolers

Mechatest/Doedijns official Benelux distributor.
Sentry sample coolers will efficiently cool your steam or hot water for any application.

Safely take boiler water samples and remain cost effective while cooling samples. Analyzers need a sample in a specific temperature range, also manual sample points needs for safety a temperature below approx. 70°C. When this temperature is different from your process temperature, a sample cooler is sometimes required. We have a partnership with Sentry, an independent manufacturer of coolers. By using sample coolers, we bring down the product temperature in a sampling system and lead it under the optimal conditions to the analyzer. We offer a width range of Stainless Steel and Alloy helical tube sample coolers.

The high efficiency sample coolers from Sentry combined with expert sampling knowledge and fast distribution by Mechatest, form an excellent combination. This helical tube sample coolers require a continuously cooling water flow, if you not have cooling water ask for our solution with a "passive sample cooler".

Mechatest delivers the Sentry helical coil sample cooler that fits your needs

To cover the difference in cooling requirements in the industry, Sentry offers a wide variety of coolers. Based on the type of sampling product and process temperature and pressure, coolers can be customized to fit the situation. 

• Design accordingly ASME PTC 19.11
• The ideal sample cooler for cooling your steam or hydrocarbon fluid samples
• Applications in hot water sampling, Makeup, Condensate, Deaerator, Boiler feedwater, Saturated steam, Main steam, Reheat steam, Superheated steam, hydrocarbon fluids
• The required materials (stainless steel, titanium and several alloys)
  
• Specific water chemistry could dictate different materials for improved corrosion resistance, e.g. Alloy 600 for high chlorides in the cooling water
• Different volumes, depending on sample size and flow rates

Keeping a sample representative is important for analysis. So, choosing the correct sample cooler helps to get reliable results from your analyzers.
