OPERATIONAL BENEFITS • One classroom – one unit • Teachers have some control over their thermostats • Redundant pumps ensure we will not lose the entire system • “Best Practices” are easily transferable from one application to another
MAINTENANCE BENEFITS • Individual classroom units can be replaced within four hours • Preventive maintenance is greatly simplified • Minimizes the use of roof-top unit • Full digital controls allow remote troubleshooting as well as trend analysis
DISTRICT UTILITY SAVINGS
ELEMENTARY YUCCA SCHOOL
ALAMOGORDO SCHOOL HIGH
DRAWBACK The only significant drawback we see at this time is a higher up-front cost . However… We believe the cost of the entire system over its life cycle will be no more or less than a conventional DX package unit system.
