The OASIS CH50 and DM12 are designed to offer exceptional performance combined with versatile installation options.

The OASIS CH50 and DM12 constitute a patented two-component modular design that allows for a smaller, more flexible footprint, while also featuring a robust 50,000 True Output™ BTU system. The CH50 houses a stainless steel tank and powerful diesel burner, while the DM12 contains circulation pumps, a potable hot water heat exchanger, and a thermal regulating valve.

The OASIS CH50/DM12 system delivers 1.5 GPM of continuous hot water at 120°F without interruption to space heating requirements. A dual-loop circulation system provides space heating to up to 5 zones.

Other standard features of the OASIS CH50/DM12 system are dual 1500 watt AC electric elements for an added 10,000 BTU of output that can be used independent of the diesel burner while under shore power and an engine waste heat management system to increase efficiency in the system. The OASIS CH50/DM12 also incorporates plug-and-play wiring for easy installation, and offers the option of an engine preheat feature to reduce cold engine start-ups.

The OAISIS CH50/DM12 can be controlled though the ITRTouch™ remote control interface, providing easy and intuitive operation and diagnosis of the system.

The OASIS CH50/DM12 is CSA/UL certified. All OASIS systems, including the OASIS CH50/DM12 use ITR’s low-pressure burner platform. This patented “no-smell, no-smoke” technology improves safety and efficiency while lengthening system maintenance cycles.
