FWU Mixing sets are compact devices intended for gradual control of efficiency (analog signal control 0 … 10V) and protection of a fluid heat exchanger by changing inlet temperature of a coolant at its constant consumption.


  • By-pass line with a balancing valve
  • Grundfos pumps
  • Flexible connectors for connection convenience (modification 1)
  • Large mixing sets without flexible connectors for rigid structure installation in-site directly (modification 2).

The mixing sets are supplied packed into the boxes having dimensions of 400х800х200 for convenience of storage, transportation and installation.

All finished FWU mixing sets are pressurized at a liquid temperature of 10 atmospheres that protects a product against any leakages under further operation. Due to this fact FWU mixing sets provide a high quality standard guaranteeing reliable and trouble-free operation of water heat exchangers.
