Many stack purchasers desire total turnkey services to include in the stack package the design, supply, delivery and installation of the stack system. Air Techniques, Inc., years ago, in the early 80’s provided our first installed steel stack. Air Techniques is a thirty year old firm with turnkey erection experience dating back to our early foundation. Since those early days, we have completed numerous successful turnkey projects. We hold contractor licenses in many states and add to this list each year. Several of the steel stack projects of which we are most proud include the demolition of an old stack with reuse of a structure or foundation.
