Insty-Pac Tube Assemblies

The Insty-Pac (patent no. 6,065,740) Multiple Tube Assembly is “job-engineered” to assure highly efficient steam release into the air stream. Each humidifier is designed for your specific capacity and duct size requirements. The Insty-Pac multiple tube assembly is designed to achieve the shortest possible dissipation distances in the industry to meet the most demanding applications.


The Insty-Pac is designed with punched orifices and is maintenance-free. The header/separator is designed to remove 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.


The all-welded design 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).
