Ribbed tubular heat exchanger


RWT 1 water-water type heat exchanger is designed for building into the water heater OKC 300–500 NTR(NTRR)/BP and OKCE 400–500 S. The electric water heater OKCE 400–1000 S may be rebuilt to exchanger water heater. The exchanger is fitted to the flanged hole of the heater.


  • It is used as a second heat exchanger for heating all volume of the heater or increasing of output of fixed built-in exchangers in the heater.
