Safety of Futron refrigeration plants with natural refrigerant

Safety comes first, especially in the use of flammable substances. That is why a perfectly functioning safety system is essential when using propane, propene and butane. To ensure safety, our products are only used by specialist personnel with many years of experience Experience and manufactured under high quality standards.

In addition, all of our devices have an ATEX gas warning system with a two-stage gas sensor, which prevents system failures due to false alarms. If the limit of 800ppm (first stage) is exceeded, the exhaust fan is switched on and the gas mixture is discharged outside. Due to the high delivery rate of the fan, an inflammable mixture can be prevented. If the limit is exceeded at 2500ppm, the device is immediately switched off, 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 2500ppm
  • Automatic extraction of foreign gases
  • Increased occupational safety through permanent gas monitoring
easily flammable

Under certain circumstances and influences, hydrocarbons are flammable. The risk exists and must be avoided by taking suitable safety precautions. An ignitable propane mixture consists of only 2.12% to 9.35% volume percent in the air. Below these limits, propane, for example, is difficult to ignite or cannot be ignited at all. The risks during the operation of the chiller are safely managed by reliable safety precautions.

Switch-on levels Action Recommended setting of the gas sensor
1. The fan conveys any escaping refrigerant to the outside safely and switches the fan off when the set value is undershot. Device remains active. 800 ppm
2. 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. 2500 ppm
