Product Meeting -----------------------------

Discussions Topics

Product Meeting Discussion

• Outsource Electric Unit Heaters• Goodman Cond Units for Space Pak• Energy Recovery Modules

– Calcana & AirXchnage• Hydronic Unit Heaters

– Become at least a me too– Specifier– Unit Mounted Controls– Upgrade Mtrs and junction box– Reznor , Modine & Rettling all becoming a threat

Product Meeting Discussion Topics

• Hydronic Unit Heaters– Production Issues

• Sharp corners and lose fit of meteal• Issue w/ Fan Blades coming off• Issue w/ Vibration

– Upgrade housing for Plastic (polish model)– All engineering done to date has been to take cost out

Product Meeting Discussion Topics

• Tubular unit Heater– Need tubular QVEB, Duct Furnace– Tubular QVEB nearly done

• Moving to separated combustion model next

– Condensing unit heater bimetal control switch to avoid freezing

– Solenoid valve for power outages to dump condensate
