    1 PRODUCT TECHNICAL SPECIFICATION 1.1 FUNCTION DESCRIPTION The construction of OKC 160 - 300 series tanks and their variety allow economic preparation of hot sanitary water (HSW) using different energy sources. Their nominal performance provides sufficient amount of hot sanitary water for flat units, premises, restaurants, and similar establishments. HSW can be heated by electric energy, different types of central heating boilers, recoverable energy sources (heat pumps, solar collectors) and combinations of those.
