BAFA funding opportunity for heating system optimization through hydraulic balancing and the installation of flow control technology

Thermostatic flow temperature limiter with adjustable minimum temperature, featuring a fixed minimum flow rate of approx. 1%

Enables, in condensing boilers (WITHOUT minimum flow rate / WITHOUT Delta-T limitation!) to maintain a constant flow temperature at variable boiler output or fluctuating return temperature by adjusting the water flow rate while fully utilizing condensing efficiency

Consisting of:

1) Actively opening valve base VUO D 200 with fixed minimum flow rate DN20

Kvs = 3.2
