Thanks to an in-house Research and Development Center, Cosmogas has created uni-que, high-quality products that stand out from the competition for several patented inter-nal components, such as R.V.C. and R.S.C. heat exchangers:
EXCLUSIVE PATENTED DESIGN – Since the early 90’s Cosmogas juggles the condensing technology designing and developping two exclusive primary heat exchangers: R.S.C. and R.V.C..
EXCEPTIONAL RESISTANCE AGAINST CORROSION – The 3 series of stainless steel round tubes, which the heat exchangers are made of, are connected to grant the highest resistance against corrosion.
HIGH EFFICIENCY – Both heat exchangers have been designed to reach an optimal exchange along the entire length of the exchanger and to grant an exceptional efficiency up to 110% with savings on heating up to 35%.
Radial Shared Circulation, with AISI 316L stainless steel wet chamber, to grant the highest resistance to corrosion, housed inside a resistant self-supporting monobloc made of stainless steel.
Radial Variable Circulation, with stainless steel AISI 316Ti (Titanium) non wet chamber without weld joints to keep unaltered the carachteristics of stainless steel, housed inside a resistant self-supporting monobloc made of insulating composite.
During the operating, return water is distributed on Ø16 and Ø18 mm round tubes series.
The advantage of such a system is to condense with 55/56°C temperatures of the return water and to have excellent outputs of the boiler even in radiators systems. In the R.S.C. heat exchanger fluid circulation is radial shared, while in the R.V.C. heat exchanger it is radial variable.
The R.V.C. “variable” circulation of the fluid allows a flue gas/water upstream thermal exchange, this sets up a high efficiency that quickly leads to flue gas condensing.
Cosmogas heat exchangers are made of 3 series of round tubes (18 and 16 mm diameter), to avoid clogging and to grant:
The innovating premix and cascade sequence control system employed in Cosmogas boilers allows an exceptional turndown ratio from 1:6 to 1:20 (and even more in case of boilers in cascade sequence).
Cosmogas ecologic premix appliances have a constant air/gas ratio in each point of the turndown range of the burner, decreasing polluting emissions and streamlining efficiency.
The round shaped premix burner is made of “Fecralloy” a special metal fibre and spreads short and perfectly nourished flames.
