Gases detected: R32

The Cool Guardian transmitter is capable of precisely detecting R32 refrigerant gas, which is becoming increasingly popular in the refrigeration and air conditioning sector. This gas is known for its low CO₂ emissions, thus contributing to reducing the environmental impact of the systems that use it. Thanks to the advanced sensitivity of the device, Cool Guardian ensures continuous and accurate monitoring of this gas, ensuring that systems operate optimally and without risks to the environment.

Operating temperature from -40°C to 50°C

The Cool Guardian transmitter is designed to operate in a wide range of temperatures, from -40°C to 50°C. This wide tolerance to extreme temperatures makes it ideal for applications in harsh environments, such as industrial refrigeration systems or outdoor environments, where temperature variations can be significant. The stability and reliability of the device in all climatic conditions ensure long life and superior performance.

IP65 protection rating

With an IP65 protection rating, the Cool Guardian transmitter is resistant to dust and water jets from any direction, making it ideal for use in industrial or outdoor environments. This protection rating ensures that the device can operate safely and continuously even in conditions of intense dust or exposure to rain or water splashes, significantly increasing the durability and robustness of the system.

Configurable relay outputs

The Cool Guardian transmitter is equipped with three configurable relay outputs, which allow the management of external loads such as alarms, ventilation or other safety devices. This flexibility allows the transmitter to be integrated into an existing monitoring and control system, optimizing system efficiency and improving safety. The relay outputs can be easily configured via the app, making management and customization operations quick and intuitive.

Configurable analog output

The device offers several analog output options: 4-20mA, 0-5V, 0-10V, 1-5V, 2-10V. Thanks to the configurability via the Seitron Guard app, it is possible to adapt the transmitter to the specific needs of the system, allowing precise analog signals to be obtained for controlling external devices. This level of customization makes the Cool Guardian particularly versatile, compatible with various monitoring and automation systems.

Modbus® output via RS485

The Cool Guardian transmitter supports Modbus® output via RS485, a standard communication protocol widely used in industrial applications. This allows up to 32 devices to be connected, allowing easy integration with other monitoring and control systems. The Modbus® RTU protocol ensures that data is transmitted quickly and securely, facilitating the management and analysis of information related to refrigerant gases.

Calibration and bump test via app

Another distinguishing feature of the Cool Guardian transmitter is the ability to perform calibration and bump tests via the Seitron Guard app. These operations can be performed directly from the mobile device, without the need for additional tools, greatly simplifying maintenance and ensuring accurate and reliable results. This functionality makes the device ideal for professionals looking for a practical and high-performance solution for managing refrigeration systems.

Integrated audible and visual alarm

To ensure an immediate response in the event of anomalies, the Cool Guardian transmitter is equipped with an integrated audible and visual alarm. This functionality allows for timely signaling of critical situations, such as refrigerant gas leaks or other system problems, allowing for rapid and timely intervention. The visual and audible alarm helps prevent damage to systems and ensures the safety of the environments in which the system operates.

Conclusions

The Cool Guardian refrigerant gas transmitter is a complete device, designed to simplify and optimize the monitoring and management of refrigerant gases in refrigeration and air conditioning systems. Thanks to its advanced features, such as R32 gas detection, resistance to extreme temperatures, configurable relay outputs, analog and Modbus® output, and the possibility of calibration via app, the Cool Guardian is an ideal choice for professionals in the sector. With an integrated audible and visual alarm and an IP65 protection rating, this transmitter ensures safety, reliability and excellent performance in any operating environment.
