Water heaters SOL

Summary

Stationry 1 MPa for solar systems
OKC 200 NTRR/SOL, OKC250NTRR/SOL, OKC 300 NTRR/SOL

Character

New line enamelled stationary indirecet water heaters for solar systems i n volumes 200, 250 and 300 litres with two exchangers for solar system and boiler system. Water heater has a circulation. There is a revision flange in bottom part of 300 litres water heater for cleaning. For using in solar systems is included G 6/4" hole for screw mounted electrical heating unit TJ 6/4.

Used in

Heating of Hot Utility Water for whole year in solar systems with electrical or indirect auxiliarty heating (gas boiler, wood or coal boiler).
