During our 18 years design and technical support, these ideas and diagrams have been hidden in our computers. The year 2017 and 2018, we built up our new website: www.modularhydronics.com for promoting most of by our clients well-known PAW and RESOL series products. Instead of presenting products one by one, we moved one more step and provided pre-engineer modular hydronic packages on this new website. "Why we still keep these diagrams in our computers" pushed us to put in order these 300 standard and custom layout diagrams based on 2-zone, 3-zone and 4-zone systems, more than 90% of them originated from real-world projects. 

Our initiative is these diagrams help you better understand how our "plug & play" modules are applied into multiple heat sources hydronic systems. The E-library encloses regular Modulation Condensing, standard Gas, oil, wood, and electrical boiler, or heat pump, and work with/without Domestic hot water, and Solar heat source.

Grundfos Direct Sensors

Grundfos VFS, RPS, VFD and RPD sensors are all two-in-one sensors working with different liquid media such as water and Glycol. Grundfos VFS and VFD measure temperature and flowrate, and Grundfos RPS and RPD measure temperature and pressure.

Resol DeltaSol MX can directly work with Grundfos Sensor VFS, RPS, VFD, and RPD.

Resol DeltaSol BX PLUS can directly woth with Grundfos Sensor VFD and RPD

Resol DeltaSol BX can directly work with VFS and RPS.
