Generally, low pressure boiler refers to that boiler pressure is lower than 1.5 MPa (15 bar). The temperature in a low pressure boiler will not rise above 120℃.Sitong Boiler is professional on low pressure boiler, and the representative low pressure boiler is thermal oil boiler, which is working under the pressure of 0.8Mpa, while it can get a relative higher temperature (320℃) than the ordinary boiler. 

Advantages of Low Pressure Boilers
Low pressure boiler is operate at lower pressure, they do not need to be monitored regularly, just need to be checked when the equipment begins to break down. These series boiler are very safe. While the high pressure boiler operate under a higher pressure (higher than 15 bar), these boilers need to be monitored to ensure safety operation. The operators has to inspect switches, valves, safety devices and leaks on a regular basis. Any malfunctions need to be fixed immediately to prevent further damage.

What is YYQW Low Pressure Thermal Oil Boiler
YY(Q)W low pressure thermal oil boiler is a kind of safe and energy saving boiler with working characteristics of low pressure (1.1 MPa) and high temperature (320℃). The heat carrier is hot oil (heat conduction oil/heat transfer oil), the circulating pump force heat transfer medium circulating in liquid phrase, and transfer heat to heat user equipment, then return to the heating furnace for reheating. The fuel could be oil and gas.
