-.- E-i -9/ Product description MXON XPO burners are low temperature burners for use in liquid backed applications, including: Water back heater ire tube boiler Thermal oil heater irect contact water heater Solution heating/tanks Snow melters XPO burners provide high efficiency operation with low requirements. They are designed for ease of retrofitting into existing liquid backed applications. XPO burners are available in two basic versions: Packaged (P) with integral combustion blower External blower (E) for use with an external combustion source for extended capacities oth packaged (P) and external blower (E) versions include two different choices for blast tube lengths. foot or foot long blast tube is available. last tube length should be selected based on the wall penetration depth or non-liquid cooled portion of fire tube. The packaged (P) version also includes a choice of blower voltage and a choice of /fuel ratio control actuators. MXON requires the use of parallel positioning control systems. or indoor, general purpose installations, use oneywell ontrolink or equivalent system. or outdoor or hazardous duty service installations, use MXON SMRTLINK MRV control systems.
