2 Description
2.1 General information
The R18 series boilers are atmospheric open flued, low thermal capacity gas-fired boilers. These high efficiency
boilers are designed to provide heating and hot water services for a wide variety of industrial and commercial
premises.
The R18 series of boilers are available in 6 types:
132, 154, 180, 210, 244 and 280.
The type number indicate the number of burner bars present in the burner assembly.
The load at nett calorific value is approximately 3,5 kW per burner.
All boiler types are fitted with an 18-tube heat exchanger of the 2 pass type.
The use of extruded copper fin pipes in the heat exchanger leads to higher efficiency.
Thermal radiation losses are minimised by the optimal construction of the combustion chamber in
which high-grade insulation is integrated.
The advanced construction of the R18 enables swift assembly and dismantle, which simplifies
maintenance and inspection.
All boilers have full sequence automatic control with overheat cut off, water flow switch, modulating turn
down on gas and combustion air (for improved efficiency at varying heat loads) and fault indicators.
The R18 has a PID temperatur regulator and electronic protection and ignition system indicator by the letters EM.
Appliance category B11.
The R18 series have CE approval for all relevant European countries. The series are registered
under the Product Identification Number 0063AQ6600.
