Patented quality product (pro-dynamic cross convection patent no. DE 10 2012 015 726.6)
The condensation control switch HYGRASREG® KW with terminal box housing made of impact-resistant plastic and with an housing cover with quick-locking screws or the cost-effective HYGRASREG® KW - SD with snap-on lid is installed on cooling ceilings, on cooling/cold-water piping or on cooled surfaces and is designed to prevent the formation of condensation. It reliably detects formation of dew by means of its humidity and temperature sensor (no conductivity measurement) and, thanks to its measuring method, pro-dynamic cross convection, yields an exact measurement result (with LED status indicator). Dew point temperature is that temperature at which air reaches the state of saturation and water vapour starts to condensate. The KW condensation control switch can be operated as a monitor on cooling ceilings or pipes so that the switching output is activated when dew builds up on the cooling ceilings of the property to be monitored and e.g. a heating system is started, or other actuators are initiated.
