Carrier’s 48PM rooftop units include microchannel technology condenser coils. Microchannel technology provides many performance and reliability benefits, that results in a more compact coil design with high coil and overall unit efficiencies. In addition, the surface of the coil is much more robust than a conventional round tube plate fin copper tube aluminum fin coil. S 0.3 fins/inch S 18 louvers per fin S 32 ports per tube (high ratio of internal wetted perimeter to flow area) S Double wall thickness on exposed tube edges S All aluminum coil S Furnace-brazed coil S Epoxy-lined shrink wrap...

Indoor Air Quality Begins With Carrier Rooftops Two-in. disposable filters are factory furnished as standard in every unit with the capability of accommodating 4-in. filters with Factory Option as well as factory-installed MERV- pleated -8 filters. Internally sloped condensate pans are self-draining to ensure minimizing biological growth in rooftop units in accordance with ASHRAE Standard 62. All 48PM16-28 units use an epoxy powder-coated steel condensate pan. Unit uses foil-faced cleanable insulation that is securely fastened. Selected panels are mechanically fastened for added support....

ComfortLinkt Control Option The ComfortLink control is your link to a world of simple and easy to use rooftop units that offer outstanding performance and value. When used with a space temperature sensor, the ComfortLink controls’ intelligence maintains control over the economizer and condenser fans and optimizes the performance of the refrigeration circuits as conditions change resulting in the following features: S Better control of temperature and humidity S Superior reliability S Automatic redundancy S Low ambient cooling operation to 0_F S More accurate diagnostics, at unit or remote...
