Through-the-Wall (Window) Harsh-Duty Industrial Air Conditioners

Durable Machinery Company, LLC offers five basic models of through-the-wall (TTW) harsh-duty air conditioners ranging in cooling capacity from 12,000 BTUH (3.5 KW or 1 ton) through 36,000 BTUH (10.6 KW or 3 tons).

I. Additional Special Features

• DMC rates these capacities at and designs the air conditioners for ambient temperatures of 131°F (55°C), not the normal rating temperatures of 95°F (35°C) used by most manufacturers. Since DMC’s patented design assures that air conditioners will maintain their full cooling capacities at lower temperatures without fan speed or other active controls, we assure that units can deliver the promised cooling throughout the year in your facilities.
• Low-ambient conditions: These units will maintain their full cooling capacity — or more — from 131°F (55°C) down to 32°F (0°C) without any modifications, and to as low as -40°F/C with adaptation.
• As ambient temperatures fall, the capacity of these air conditioners increases by up to 20-25% above their rated capacities at standard rating temperatures of 95°F (35°C). Even at 120°F (49°C), they will provide substantially more cooling than their rated capacity.
• Thermostats in DMC air conditioners can be adjusted to maintain temperatures inside the cooled space as high as 105°F (41°C) to 110°F (43°C). Therefore, if your building merely needs to be kept from overheating, our air conditioners can substantially reduce your energy costs by cooling only when solvents, explosives, other products, controls or equipment actually need cooling and not force your system to run cooler than necessary.
• In fact, you may be able to utilize a smaller-capacity air conditioner because you will not need to operate it at lower temperatures. A high room temperature will also increase the life of the air conditioner.
• Through-the-wall air conditioners can be mounted through a window, but they generally weigh more than window units because they are more robust and, therefore, require more support. DMC offers optional 316L stainless-steel support brackets for its TTW air conditioners
• DMC through-the-wall air conditioners have all key components mounted on a slide-in insert so that they can be removed for maintenance and repair and remounted quickly.
