Ammonia (NH3) in Refrigeration

Ammonia (NH3) is the most common choice of refrigerant for many industries including food and beverage, HVAC, schools, laboratories, hospitals, and many others. Because of this, ammonia detection is more important than ever. Anhydrous ammonia can cause an immediate danger to life and health at only 300 ppm, and is explosive in certain conditions.

Utilizing our SenSmart Gas Detectors and ViewSmart Alarm Controllers we can provide complete ammonia gas detection and alarm control solutions. Installing sensors in colde environments, such as those you find with ammonia refrigeration, is no issue for RC Systems' ammonia (NH3) sensors, as they have heated sensor elements helping to lower their operating temperature range to -40C. RC Systems has a professional engineering team ready to provide solutions for ammonia gas detector system engineering, from system design with detailed wiring diagrams, to site startup and commissioning services.
