RL/B MZ series burners are characterised by a modular monoblock structure that means all necessary components can be combined in a single unit thus making installation easier, faster and, above all, more flexible. The series covers a firing range from 1250 to 4450 kW, and they have been designed for use in hot water boilers, overheated water boilers as well as steamboilers. Operation is 2 stages. The innovative combustion head is able to reach good performances in term of Low NOx and helps in reducing noise emissions.
