Thanks to an in-house Research and Development Center, Cosmogas has created unique, high quality products that stand out from the competition for several patented internal 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 developing 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%.

2 Unique Patented Heat Exchangers MADE in COSMOGAS
R.S.C. Heat Echanger
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.
R.V.C. Heat Echanger
Radial Variable Circulation, with stainless steel AISI 316 Ti (Titanium) not wet chamber without weld joints to keep unaltered the carachteristics of stainless steel, housed inside a resistant self-supporting monobloc made of insulating composite.
Operating and advantages of R.S.C. and R.V.C. heat exchangers Made in Cosmogas
During the operating, return water is distributed on 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, to avoid clogging and to grant:
LARGE WATER FLOW
GREAT EXCHANGE SURFACE
LOW PRESSURE DROPS
HIGH WORKING PRESSURE (up to 11 bar)
COSMOMIX patented premix system
The innovating premix 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).
Advantages
TURNDOWN RATIO FROM 1:6 TO 1:20
NEGATIVE PRESSURE GAS VALVE
IT ALSO OPERATES WITH LOW GAS INLET PRESSURE UP TO 7,5 mbar
CONSTANT AIR/GAS RATIO
Ecologic premix burner
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.
Advantages
HIGH EFFICIENCY COMBUSTION
LOW POLLUTING EMISSIONS
(CO < 15 ppm AND NOx < 15 ppm)
NATURAL GAS AND LP GAS OPERATING
