Good afternoon! Comrades, my name is Artem, I am from Ukraine and I am very glad that I found your forum on the Internet. At the moment, we do not have a similar place with so many people involved in the topic of supply ventilation and heat exchangers. My position is related to the production and development of heat exchangers. For the full picture, I don't have enough technical data about the manufacturer CORE, perhaps some of you have access to their selection program and can share it with me? https://core.life/ https://selection.core.life/eRep/ In any case, thanks!
