NT Series Cores
Maximum heating power for large RVs
The 12-volt DC Suburban NT Series furnaces, offered in capacities from 30,000 to 40,000 BTUH, are examples of how powerful a compact ducted furnace can be. Cabinet size is the same on all models, providing a standardized size with four capacity options.
NT Series furnaces, with side or bottom duct options, are easy to install and make an ideal replacement for obsolete competitive furnaces.
