LDWO SERIES—Oil-fired/Hot Water

A Caravan modular boiler system consists of two or more compact cast-iron boilers that offer significant advantages in terms of installed cost, efficiency and reliability. Caravan systems are based on step-firing just enough modules to meet hot water or space heating demands. LDWO systems are available in 602,000 to multi-million Btuh gross input.

For additional information, see Caravan Engineering Manual, pub. C-30 and Caravan oil application guide, pub. CG-10-HWO.
