SRPN28B Cool Guardian R717 (NH3): Refrigerant gas detector with electrochemical sensor for R717 (NH3); measuring scale: 0...100 ppm by Seitron Americas
Cool Guardian Refrigerant Leak Detector, uses fast response time, low-temperature performance (-40..+122°C / -40..+50°F), and integrated audio and visual alarms, simplifies and facilitates compliance and safety regulations.
Modern refrigeration systems are engineered for optimal efficiency and airtight integrity. However, improper installation, unintentional damage, or mechanical wear and tear can potentially lead to dangerous gas leaks.
In this context, Cool Guardian gas transmitter serves as a vigilant guardian against unforeseen leaks, which could compromise both the environment and human health.
Applications
Selection of the appropriate gas sensor to monitor the presence of refrigerants in industrial processes, commercial cooling systems, or refrigeration facilities is crucial when it comes to fixed gas transmitters. These transmitters are designed to accurately detect and measure various refrigerant gases, providing essential data for maintaining the integrity of refrigeration systems and preventing potential leaks.
Industrial Refrigeration
Large-scale refrigeration systems in industries like food processing, pharmaceuticals, and cold storage facilities rely on refrigerant gas. Leak transmitters help detect leaks promptly, preventing environmental damage and ensuring the safety of workers.
Mechanical Rooms
Mechanical rooms can pose safety risks due to the presence of different gases. Refrigerant gas leak transmitters continuously monitor the environment for leaks, ensuring the safety of personnel working in these areas by promptly detecting any gas leaks.
Process Cooling / Chillers
Chiller systems often use refrigerants to maintain specific temperatures for industrial processes. Leak transmitters provide continuous monitoring, ensuring that any leaks are promptly detected to prevent disruptions in the cooling process.
HVAC Systems
Heating, ventilation, and air conditioning (HVAC) systems in commercial buildings, hospitals, hotels, and shopping malls use refrigerants. Leak transmitters aid in monitoring and detecting leaks.
Laboratories and Research Facilities
Laboratories, especially those handling sensitive materials or operating with precise temperature control, utilize refrigeration systems. Leak transmitters play a critical role in maintaining the integrity of experiments and preserving samples by promptly detecting leaks.
