The Fresh-r is the only heat recovery ventilator available that also works with maximum efficiency in freezing temperatures. So Fresh-r is the only heat recovery ventilator that’s ready for NZEB.
On average, there are 58 days of freezing temperatures in the Netherlands each year. And on all of those days, Fresh-r continues to ventilate with heat recovery. The Fresh-r is the only heat recovery ventilator that simply keeps working in freezing temperatures. All other solutions have a ‘bypass’. This means that no heat is recovered. And those are precisely the moments when the temperature difference is greatest.
