BIASI Technologie

BIASI boilers are single-spiral heat exchangers with a large water space, developed in 2016 and made of 14 mm pear-shaped tubes. A key development was that the 0.7-1 mm gap between the coils allowed the unit to be equipped with a 250 Pascal fan. This gives the designer and contractor more freedom, as the maximum allowable outlet distances (60/100: 10 m, 80/125: 20 m and 80/80: 40 m) increase the number of installation options. This type of heat exchanger also allows a modulation range of 1:10 and quiet operation because the "pears" are placed side by side, so that the exhaust velocity of the combustion products is maximized only at the smallest section at any given time. If the heat exchanger pops out, it can be easily repaired, as there are no parallel pipe configurations. The boilers do not calculate the modulation demand based only on the supply and return water temperatures, From mid-2017, Biasi boilers will be equipped exclusively with these heat exchangers (Inovia Cond PLUS and Rinnova Cond PLUS). The main components are products developed by SIT, such as the gas valve, control panel and fan.

 The diverter valve is located in the front branch of the heating hydraulic block, and it is much easier to determine the pipe allocation at the boiler connection points, because in this case, due to the location of the front branch of the diverter valve, we have two front branches for the heating and hot water side and only one return branch, and in this case it makes sense to have a BIASI magnetic sludge separation filter located in the heating return branch. A smart control panel helps the service technician not only during commissioning, but also during maintenance. This process is facilitated by the ability to read from the menu program the instantaneous ionization current measured at the electrode in case it needs to be replaced. Also helpful for maintenance is the ability to measure the instantaneous HMV value from the device's menu. This can also determine if the secondary heat exchanger needs to be acidified or replaced. A room thermostat for the secondary circuit can be connected to the control panel and will activate the pump or zone valve of the newer heating circuit when heating is required. The company's appliances are already fully compliant with the new ErP 2018 requirements with NOX class 6.
