YQ(Y)L series gas-fired/oil-fired thermal oil heater
The YQL series oil/gas thermal oil boiler adopts a two-pass round coil structure. The end of the coil tube is tapered, effectively protecting the end furnace wall of the boiler. It is equipped with advanced combustion equipment, and the operation of the boiler is fully automated. The boiler is shipped as a whole and can be put into operation just by connecting the gas (oil) and electricity after it is in place on the site.
