Non-Freeze Steam Distributing Coils

Steady Heating for Extreme Conditions

Non-freeze steam distributing coils are designed to deliver heat from steam, even in below-freezing weather. The non-freeze steam coils supplied by Precision Coils are readily customizable for new systems or retrofits and optimize HVAC performance in cold-weather applications.

How Non-Freeze Steam Coils Work

Non-freeze steam distributing coils are designed to provide consistent heat in HVAC systems operating in low ambient temperatures. Unlike a standard steam coil, a steam distributing coil utilizes a tube-within-a-tube design that distributes steam evenly throughout the coil surface.

Steam circulates continuously through the coil while condensate is removed during operation to help prevent freezing within the tubes. Even steam distribution across the coil helps maintain consistent heat output throughout the entire coil face. This design allows steam-distributing coils to operate reliably in outdoor air systems and other applications exposed to cold weather conditions. Precision Coils manufactures custom HVAC coils, including steam distributing coils, for replacement and OEM applications.

Key Design Features

Precision Coils designs non-freeze steam distributing coils to support reliable operation and freeze protection in demanding HVAC applications. Multiple steam supply connections and steam distribution headers help maintain even steam flow throughout the coil.

Proper condensate removal is critical to prevent freezing and maintain heat transfer. Steam traps and piping configurations are designed to allow condensate to drain continuously during operation. Coil construction, material selection, and dimensional fit must also align with system airflow and operating conditions. Precision Coils manufactures custom steam-distributing coils designed to fit existing air handling units, ductwork, booster coils, and retrofit applications.

Specification Selection for Non-Freeze Steam Distributing Coils

Like any coil, certain factors must be taken into consideration when selecting or designing steam-distributing coils for an HVAC system. The engineers at Precision Coils use their extensive knowledge to help customers design coils specifically for use in their HVAC systems, optimizing heat transfer and system efficiency. The relevant specifications for custom-engineered distributing steam coils are listed below:

Steam Pressure: HVAC systems have specific steam pressure requirements, and non-freeze steam coils must match those pressure requirements.
Airflow Rates: Applications with higher air speeds may require larger steam-distributing coils or coils with more rows for adequate heat transfer.
Materials: Depending on the application of your non-freeze steam coils, they can be constructed with copper fins for better heat transfer.
Dimensional Fit: Our team makes certain that the dimensions of custom-engineered coils properly fit the existing ductwork or air handling unit.
Condensate Removal: Proper piping and traps must be incorporated in the non-freeze steam coil design to avoid condensate buildup.

Applications for Non-Freeze Steam Distributing Coils

Steam-distributing coils are used in HVAC systems required to maintain consistent heat in extremely cold conditions. Some of these applications include:

Commercial and Industrial Air Handling Units
Hospitals and Laboratories
Schools and Municipal Buildings
Manufacturing Sites
HVAC Systems in Cold Climates

Applications in Cold Environments

Non-freeze steam distributing coils are commonly used in HVAC systems operating in cold climates or applications exposed to outdoor air. Typical applications include:

Outdoor air systems
Make-up air units
Industrial ventilation systems
Schools and municipal buildings
Hospitals and laboratories
Commercial and industrial HVAC systems

Industrial facilities also utilize non-freeze steam coils in process heating and ventilation applications requiring reliable operation and consistent heat output. In some HVAC systems, steam distributing coils may be used alongside a chilled water coil or other HVAC coils, depending on system requirements.

Benefits of Distributing Steam Coils

Freeze Protection: The tube-within-a-tube design of non-freeze steam coils helps reduce the risk of condensate freezing by continually moving air through all sections of the coil.
Efficient Heat Transfer: Steam-distributing coils offer consistent heat output from all areas of the coil surface, minimizing variations in temperature.
Durability: Distributing steam coils is built using high-quality materials to endure the high pressure and thermal expansion from steam.
Energy Savings: Non-freeze steam distributing coils deliver even steam distribution to avoid energy waste and maintain optimal steam pressure.

Advantages Over Standard Steam Coils

Non-freeze steam distributing coils provide additional freeze protection compared to standard steam coils. Their internal design helps maintain steam circulation and condensate removal throughout the coil during operation.

In applications exposed to low ambient temperatures, steam-distributing coils help reduce the risk of frozen coils, system downtime, and equipment damage. Our team works with customers to determine whether standard steam coils or non-freeze steam distributing coils are appropriate based on system requirements and operating conditions.

At Precision Coils, we manufacture and supply custom-engineered non-freeze steam distributing coils tailored to customers’ precise measurements. For more than two decades, our team has helped customers design-build steam distributing coils for replacement or OEM, delivering top-tier coils with unmatched speed and service quality.
