Atmospheric Steam Applications

“Job-engineered” to assure highly efficient steam release into the air stream. Designed to your specific application to achieve the shortest possible dissipation distances in the industry to meet the most demanding applications. In addition, our standard Insty-Pac provides more efficiency than other insulated grids due to its tube-within-a-tube design.


The Insty-Pac is designed using 100% steam jacketed injection tubes with punched orifices and is maintenance-free, removing condensate before it enters the tubes. The tube-within-a-tube design means the desired steam jacket is only hot during a call for humidity, eliminating additional unwanted heat gain when no humidification is required.

Construction & Installation

The all-welded design using 304L stainless-steel construction eliminates the use of o-rings and couplings that may cause leakage and require maintenance. The Insty-Pac tube assembly ships factory-assembled for fast and easy installation into ducts or air handlers. Can be used with any of our atmospheric style humidifiers (GX, SX, ES, EC Series Humidifiers).
