Ratings are the manufacturer’s published capacities at -20°F suction for the ambient shown. A dash means the figure is not published for that model — call 954-237-6753 and we will confirm it.
Evaporators used with this system
These are the R-448A low-temperature unit coolers used with a 2-1/2 HP condensing unit. The evaporator is what decides the room: a low-temperature coil makes it a freezer, a medium-temperature coil makes it a cooler.

Grouped by published capacity against this horsepower class. Note that the two ratings are published at different conditions — the condensing unit at the ambient and suction temperature shown above, the unit cooler at its rated temperature difference — so the BTU figures are not meant to be read against each other one for one. On low-temperature systems the coil is deliberately sized for a small temperature difference, so its rating normally reads higher than the condensing unit’s. The final evaporator for your job depends on the box size, the door traffic, the product going in and the ambient around it — we do that calculation for you before anything is quoted.
