PTAC - Suburban Dynaline

Dynaline 3

City Cool Air, Inc

Economical gas heat and high efficiency electric air conditioning for year-round savings and comfort.

Dynaline developed the first gas-fired package terminal air conditioner (PTAC) in 1985 called Dynaline. Now, in its 3rd generation design, Dynaline is a leading supplier to the senior housing industry as well as other small commercial markets.

The standard 42×16″ wall sleeve makes Dynaline 3 the right choice for new construction or direct replacement for other brands such as Island Aire. Gas (Natural or LP) connections can be inside or outside the room.

Each unit is individually controlled so comfort levels can be set for each room or zone. The top-mounted controls provide for High and Low speeds in both heating and cooling modes, plus a fan only mode. The Dynaline 3 can be controlled from the unit or from a wall thermostat.

The Dynaline 3 is available in four standard colors, plus stainless steel and in unlimited custom colors.

  • Champaign Beige
