The 4AK portable air conditioning units have been redesigned. They are now available in 1-5-ton air-cooled models and 3/4 - 2-1/2-ton water-cooled units. All of the new units, except for the 5-ton air-cooled model, are sheathed in brushless stainless steel for an appliance-like finish. In addition, all of the new models incorporate electronic controls with an available infrared remote control for user convenience. The new controls include a number of built-in safety and diagnostic features.
