The Infinity Low NOx 55i is capable of supplying in excess of 820 litres per hour raised 50˚C making it an ideal choice for high capacity light commercial to large industrial system specifications as up to 25 units can be cascaded to supply any specification.
The Infinity Low NOx range incorporates patented down firing pre-mix burner technology meaning that the appliances produce less than 20ppm NOx future proofing the systems against legislative changes.
