New Transducer for Ammonia Refrigerant Applications

Given growing concern about global climate change and ozone layer depletion, ammonia and other natural refrigerants are an attractive choice to replace potent greenhouse gases in refrigeration and cooling systems. However, ammonia’s high corrosiveness and toxicity present significant challenges for system designers and engineers. Even the smallest leaks can endanger workers or a facility. This is why customers need a reliable and accurate pressure transducers to play a critical role in maintaining system integrity. Ammonia is often incompatible with the wetted materials most frequently used in fluid vessels and tubing, especially copper or copper alloys like brass and bronze. Therefore, systems designed to handle ammonia require every wetted component to be constructed with suitable materials, such as stainless steel. Failure to do so will likely result in component failure and a containment breach, allowing poisonous ammonia to escape into the surrounding environment. Ashcroft’s new E2G transducer has been designed for challenging applications such as ammonia. Made with all-welded 316L stainless steel, which is resistant to ammonia’s corrosive properties, making the E2G fully compatible with ammonia-based systems. It’s the perfect complement to Ashcroft’s pressure gauges for ammonia refrigerant. The E2G is available in absolute, gauge and vacuum-based pressure ranges. The E2G has been designed for maximum reliability through extensive testing and it is 100% leak tested to guarantee its integrity in your application. Every Ashcroft transducer is custom made to meet your application requirements. Contact us to help specify the best configuration for your application.
