The OASIS NE-S is the most powerful diesel-fueled hydronic heating system on the market, introducing new opportunities for comfort to luxury coach owners.

The OASIS NE-S produces 85,000 True Output BTU, and provides continuous 120°F domestic water at flow rates of 3 GPM. This is enough hot water to operate two showers simultaneously, without interrupting space heating demands. Two 1500 watt AC electric elements provide an additional 10,000 BTU to the systems when connected to shore power, reducing diesel burner run times, an efficiency that is further improved through the latent heat capacity of a huge 13.75 gallon marine-grade stainless steel coolant tank.

Additional standard features in the OASIS NE-S system include dual-loop circulation for space heating to up to five zones, engine waste heat management, plug-and-play wiring for easy electrical hook-up, and comprehensive on-board diagnostics. An engine pre-heat system to prevent cold engine starts is an available option. OASIS NE-S operations can also be enhanced with the ITRTouch™ remote control interface, a simple and intuitive means of operating, controlling and diagnosing the OASIS NE-S system.

All OASIS systems are UL/CSA certified, and all OASIS systems are built on a low-pressure burner platform: a patented “no-smoke, no-smell,” technology which improves efficiency and lowers system maintenance cycles.
