Raypak has taken the design technology for modulating boilers to the next level with the all new MVB. By precisely matching the latest control and combustion components, the optimum fuel air ratio is maintained throughout the entire range of load-tracking operation, even with low and fluctuating gas pressures. A 4:1 turndown capability (503-2003) ensures the exact input to match the heating demand and maximizes efficiency at all firing rates. With all copper and optional bronze waterways, these boilers provide the ultimate in corrosion resistance.
