Question about our products


Safety is the top priority

If people are trapped in cold or deep frozen rooms or warehouses, the chance for survival is low, only possible for a few hours. So there is not much time in which the enclosed can draw attention to themselves. Therefore, appropriate emergency call devices are required in all commercial refrigeration rooms. According to EN378-1 this applies to all cooling rooms with a volume above 10m³ and a room temperature below 0 ° C. Observe also the BGR 500 chapter 3.10, as well as the older regulations UVV VBG 20 and the BGV D4. But emergency call is not equal emergency call! 


How sure are you that your alarm system works in case of an emergency?

Many emergency call systems on the market have, for example, no self-test function or they are operated with obsolete battery technology, which in the event of a mains power failure may not provide any security at all. On some systems, there is not even a function that checks the battery power - it comes to a serious case of a tragic saving in the wrong place! All Hemstedt alarm systems are therefore operated with lithium-ion batteries and have extensive self-test functions, which ensure a reliable function at all times. The status of the devices is clearly indicated by LEDs and calls for a test or maintenance in regular cycles or when necessary. 

Our products also run on fuel cell / hydrogen technology!
