With a cooling capacity of 77,500 BTU/hr, the AC 6200 from ARID-Dry “cools quietly, operates at the lowest decibel level for portable air conditioners, is ideal for temporary cooling in offices, meeting areas or classroom, and features backward-inclined plenum evaporator and condenser fans,” the company said.

The AC 6200 performs at a wide range of temperatures and altitudes with a thermostatic-expansion valve not found in ordinary units.
