Steam Coils

Steam Coils

Steam is a powerful heating medium capable of carrying massive amounts of thermal energy. However, it requires a robust coil design to handle high pressures, extreme temperatures, and the destructive potential of water hammer. Alpha Coil’s steam solutions are built for industrial-grade durability.

  • Standard Steam Coils: Ideal for applications where the steam load is constant and the incoming air temperature is consistently above freezing. These coils feature heavy-walled copper or stainless steel tubing to handle the internal pressure, making them perfect for industrial drying, process heating, and large-scale building warmth.
  • Steam Distributing (Non-Freeze): For fresh air intakes in cold climates, our “Non-Freeze” distributing coils are an engineering necessity. Utilizing a “tube-in-tube” design, the inner steam-carrying tube features precise orifices that distribute steam evenly across the entire length of the outer finned tube. This eliminates cold spots and ensures that condensate is quickly removed, preventing the catastrophic freezing and tube bursting common in standard designs.

FREQUENTLY ASKED QUESTIONS

General Questions

The most accurate way is to provide us with the original manufacturer’s part number or the model number of the air handling unit. If that information is unavailable, our team can guide you through a field-measurement process or provide a measurement template to ensure an “Exact-Fit” replacement.

Yes. We specialize in “OEM-Equivalent” replacements. We maintain a vast database of specifications for major brands, allowing us to manufacture coils that match or exceed the performance of the original equipment at a more competitive price point and often with faster lead times.

A picture of the coil tag is best. If coil tag is not available, we can provide a drawing to note your coil details. We typically need the coil type (water, steam, DX, etc.), dimensions (finned height, finned length, and number of rows), fins per inch (FPI), and the material requirements for the tubes, fins, and casing.

While we provide comprehensive help for self-measurement, we can also coordinate with local mechanical contractors or technicians to assist in complex site surveys for large-scale retrofits or highly specialized industrial applications.

Absolutely. Replacement is the perfect time to upgrade. If your original coil failed prematurely due to corrosion, we can upgrade your new coil to stainless steel, cupro-nickel, or add a specialized protective coating.

Because all HVAC systems have unique dimensions and performance requirements, our coils are “built-to-order.”
