Specific Systems® Air Conditioners hold up to the harsh environments that the IDS drilling system and drive houses are built to operate in. Their industrial and explosion proof HVAC units have helped us win projects since our customers know they are getting a low maintenance product that lasts. The service support staff is always willing to help during installation, and the sales team is great about getting quotes back to us quickly.

— Keith H., Integrated Drive Systems

Your assistance with sizing and selecting the custom air conditioning equipment to condition the new 400hp and 1000hp drives was greatly appreciated. Your ability to provide information on a timely basis was an asset to our fast-paced project. The custom cabinetry sizes of your equipment gave us the flexibility needed to make the design work in the confined spaces we had available to us.
