RedBin-FR ATEX Frost Protection Thermostats
The RedBin-FR… frost protection thermostat is a revolution in HVAC systems, in chemical, pharmaceutical, industrial and offshore/onshore plants, for use in hazardous areas zone 2 (gas) and zone 22 (dust).
Description
Highest protection class (ATEX) and IP66 protection, small dimensions, universal functions and technical data guarantee safe operation even under difficult environmental conditions.
All frost protection thermostats are programmable on site without any additional tools. The switching point is scalable within the maximum ranges.
– No addional Ex-i module required
– Integrated Ex-e terminal box
– Power supply 24 VAC/DC
– LED switching state indication
– Compact design and small dimension
– IP66 protection
