Character

The OKC 200 - 300 NTRR/SOL heaters are indirect heaters designed for preparation of hot service water by means of a solar system. 

The OKC 200, 250 & 300 NTRR/SOL water heaters are designed and manufactured as a part of a solar system containing additional integral elements of the system, such as sun collectors and their roof holders (flat roof stands), expansion tank, collector filling distribution and other items necessary for proper and trouble-free function of a solar system. 

OKC NTRR/SOL - Stationary heater with two coil exchangers for heating HSW with heating water from two sources. Reheat can be carried out by the boiler in the top exchanger and also by the electric element TJ 6 / 4“.

Used in

Heating of Hot Service Water for whole year in solar systems with electrical or indirect auxiliarty heating (gas boiler, wood or coal boiler). Their nominal performance provides sufficient amount of hot water for flat units, premises, restaurants, and similar establishments.
