CX(s) Applied: A9, B5.1

Dodge City, Kansas is proposing to install a 100 ton Ground Source Heat Pump to service the local Northwest Elementary school. The system will be installed on the school's old playground. The system will be closed loop and will circulate propylene glycol as a heat transfer medium. High-density polyethylene piping will be used and all piping will be fusion welded and pressure tested to International Ground Source Heat Pump Association standards for each borehole before it is commissioned. The boreholes will be 240 feet in depth and will be completely encased by thermal enhanced bentonite grout, mitigating the risk of ground water contamination from surface run-off.
