Airswitch & bellows
20 June 2017
When Raecom Emergency Alarms, which specialises in wireless alarms systems for leisure facilities, developed a range of products based on air switching, it chose Herga Technology for its component level solutions.
Raecom’s sauna and steam room alarm is a dual air pressured system that features internal and external activation. A Herga 6439 series bellow is located inside the cabin and connected through an air tube to an outside console containing a Herga 6871 airswitch.
The outside console also includes bellows actuation and if either bellows is depressed the airswitch activates the alarm. The system contains no electronics and is designed to offer effective and reliable alarming in harsh conditions with high levels of heat and humidity.
Herga 6439 series bellows are designed for foot or hand operation so alarm placement is arbitrary. The green colour chosen by Raecom is one of many standard options that also include side or rear tube entry, base plates in various colours in addition to choices of curly coils and tube types and lengths. Herga’s well proven 6871 series airswitch range is available in a wide choice of latching and momentary action formats.
All Herga air switching products are designed to operate with large air volumes for ease and reliability of operation. Customised versions are also available.
