Our Team

Jerzy Hawranek – Technical Director

The author and designer of the RVU, and principal founders of Rehact AB and iRWN sp. z o.o.
An enthusiast of energy saving since childhood. When he was 12, he bet the operator of the boiler room in the building where he lived that the furnace would use 30% less coal if run continuously rather than twice a day. He won.
In 1974, he left for Sweden in search for practical knowledge about heat pump technologies. In 1978, stuck in traffic jams in Stockholm, he came to the conclusion that cars waiting at traffic lights emit unnecessary fumes into the atmosphere. This was the inception of the “Start & Stop” system patented by Jerzy Hawranek. However, more than 20 years had to pass before the idea of reducing car emissions and fuel consumption could be implemented in practice. Today, any respectable car manufacturer boasts the use of the Start & Stop system in their cars.
In 1982, he started working as a designer in Autoliv Development AB. In 1984, he developed a secure seatbelt locking solution, which was later patented by Autoliv. This facilitated rapid development of the company. Nowadays, Autoliv is among the major enterprises in the industry.
As he was building his own house, he developed an inlet air ventilation technology which combined the benefits of underfloor heating and a heat pump. Throughout In 1988, he started introducing the Water Underfloor Heating (WOP – Wodne Ogrzewanie Podłogowe) and Heat Pump (PC – Pompa Ciepła) technologies into the Polish market.
He has been cooperating with the major companies in the industry: Uponor, Danfoss, Systemair, Swegon and Climatwell. In 2008, he received the prestigious Best CSR Entrepreneur award from the hands of Princess Victoria for the RVU unit, which is an integral part of RES technology.
