tested, dehydrated, sealed and shipped with a holding
charge.
Durable Finish - Coil casings are made of pre-painted steel.
The pre-treated flat galvanized steel provides a better paint to
steel bond, which resists corrosion and rust creep.
Optimum Heat Transfer - Using the latest in heat transfer
technology, staggered rows of rifled copper tubes are
mechanically expanded into aluminum fins to provide opti-
mum air to surface contact for ample moisture removal as
well as high performance ratings.
Optional Factory Installed Thermal Expansion Valve -
Provides flexibility to match high efficiency applications at a
lower installed cost.
Yorkmate Refrigerant Control - Provides optimum system
performance and the flexibility to match coils with any effi-
ciency level cooling or heat pump system.
