Slant/Fin Caravan LDWO-1100-3-6 Specifications

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.
