Safety of Futron refrigeration systems with natural refrigerants
Safety comes first, especially when using flammable substances. That is why a properly functioning safety system is essential when using propane, propene and butane. To ensure safety, our products are manufactured exclusively by qualified personnel with many years of experience and in accordance with high quality standards.
In addition, all our devices are equipped with an ATEX gas warning system with a two-stage gas sensor, which prevents system failures due to false alarms. If the limit of 2000 ppm (first stage) is exceeded, the exhaust fan is switched on and the gas mixture is transported to the outside. The high delivery rate of the fan prevents a flammable mixture from forming.
If the limit of 4000 ppm is exceeded, the device is immediately disconnected from the power supply, but continues to be monitored and ventilated by the gas sensor.
Advantages of the gas system:
- No system failures due to foreign gases at concentrations below 4000 ppm
- Automatic extraction of foreign gases
- Increased occupational safety through continuous gas monitoring
Hydrocarbons are flammable under certain circumstances and influences. The danger exists and must be avoided by taking appropriate safety precautions. A flammable propane mixture exists at only 2.12% to 9.35% by volume in the air. Below these limits, propane, for example, is difficult or impossible to ignite. The risks during operation of the refrigeration machine are safely managed by reliable protective measures.
| Switch-on levels | Action | Recommended setting of the gas sensor |
|---|---|---|
| 1. | The fan safely transports any refrigerant that may escape to the outside and switches off again when the set value is not reached. The device remains active. | 2000 ppm |
| 2. | The refrigeration machine is disconnected from the power supply. The fan safely transports any refrigerant that may escape to the outside. The device remains disconnected from the power supply and must be manually released. The ATEX gas sensor remains active at all times. | 4000 ppm |
1. Switch-on levels
Action
The fan conveys any escaping refrigerant to the outside safely and switches the fan off when the set value is undershot. Device remains active.
Empfohlener Einstellwert des Gassensors
800 ppm
2. Switch-on levels
Action
The chiller is switched off. The fan conveys any escaping refrigerant to the outside safely. Device remains de-energized and must be released manually. The ATEX gas sensor always remains active.
Empfohlener Einstellwert des Gassensors
2500 ppm
