Research & Development


Kozanlar has a high technology test laboratory for research and development. We can simulate product as working on field and able to measure temperatures, flowrates, pressures.

The HIU represents the most modern technology, and provides the answer to stringent demands for long-term performance.

High comfort

HIU has individual temperature setting for hot water. Heat is automatically regulated with thermostatic valves, depending on the temperature desired inside the apartment. Domestic hot water is heated separately in a high-capacity heat exchanger; thus ensuring that the hot water is always as fresh as the incoming cold water mains supply.

Simple Installation

Compact dimensions, light weight, well arranged plumbing and factory-complete internal connections all make installation very simple.

Long-term security

The DGI represents the most modern technology, and provides the answer to stringent demands for long-term performance. The heat exchanger plates and all piping are manufactured in acid-resistant stainless steel or copper. All components are closely matched and carefully tested for function in accordance with Kozanlar quality assurance system ISO 9001:2008. DGI is CE marked.
