energy-saving GPS Single PWM Grundfos
Pump groups
Solarstation
The GPS SINGLE PWM is a solar station equipped with an energy-efficient Grundfos UPM3 15-75 electric pump.
GPS SINGLE PWM ensures significantly lower power consumption than typical solar stations with asynchronous pumps. The station meets the requirements of Commission Regulation (EU) No 622/2012 on ecodesign requirements for circulation pumps.
The flow rate is regulated depending on the collector flow temperature and the storage tank temperature. This type of solution ensures maximum energy yield while at the same time ensuring a long service life for the solar collectors. ¾" threaded connections enable quick installation with stainless steel corrugated pipes.
