Standard Steam Coils

Steam Coils for Efficient Heating

Unlike non-freeze steam coils, standard steam coils are built with -pass tubing in which steam enters, condenses, and exits as condensate. For situations where freezing isn’t a significant risk, the custom steam coils manufactured by Precision Coils provide a means of efficiently increasing air temperatures in ventilation systems, air handling units (AHU), ductwork, and other commercial and industrial HVAC applications.

Benefits of Steam Heating Systems

Precision Coils manufactures standard steam coils designed to provide rapid heat-up times and consistent heating performance in commercial and industrial HVAC applications. Steam delivers heat quickly as it condenses within the coil, allowing air temperatures to increase efficiently with minimal delay. This makes steam coils effective for process heating and applications where fast response times are required.

In facilities where steam is already available, steam heating systems offer a cost-effective solution without requiring additional heating sources. Standard steam coils deliver high heat output in a compact footprint and are commonly used in air-handling units and duct systems. Precision Coils offers both standard steam coils and custom steam coils to meet specific system requirements and performance needs.

Key Design Considerations

Precision Coils designs standard steam coils with proper condensate drainage to maintain performance and reliability. Steam must fully condense and be removed from the coil to prevent water accumulation, which can reduce heat transfer and lead to corrosion. Trap design and proper piping are required to ensure condensate is discharged efficiently.

Material selection also impacts long-term performance. Standard steam coils are commonly constructed with copper tubes and aluminum fins to provide efficient heat transfer. In applications requiring different performance characteristics, Precision Coils can design custom steam coils or alternative configurations, such as a steam distributing coil, based on system requirements. Coil construction must account for operating pressure, airflow, and installation conditions to ensure reliable operation.

Specifications for Proper Steam Coil Selection

If you’re looking for precision-engineered steam coils, Precision Coils’ experience is invaluable in selecting the proper steam coils for specific HVAC requirements. Our engineering team takes multiple factors and specifications into consideration when designing custom coils:

Steam Pressure and Temperature: The design of steam heating coils must correspond with the temperature and pressure of the existing steam system. Higher pressures necessitate a different coil construction.
Airflow Requirements: The air velocity and volume of an HVAC system are used to calculate the size of the steam coil and the number of rows required.
Material Selection: Replacement steam coils with copper tubing and aluminum fins are a common construction offering high heat transfer, but specific coatings may be necessary for steam coils in corrosive or high-humidity environments.
Condensate Removal: Ensuring your standard steam coils have proper condensate trapping and drainage is critical for preventing corrosion and maintaining heat transfer efficiency.

Steam Coil HVAC Applications

Standard steam coils are used in HVAC applications where freezing temperatures are not a major concern. Provided there’s no great risk of freezing, steam coils are used in the following applications and facilities.

Commercial HVAC Systems
Industrial Process Air Heating
Institutional Facilities such as Schools or Hospitals
AHU and makeup air units
Drying Processes in Manufacturing

Applications Expanded

Precision Coils standard steam coils are used in air handling units and duct systems where consistent heating is required. In manufacturing environments, steam coils are used for process air heating and drying applications where stable temperatures are needed. Institutional facilities, including schools and hospitals, use steam coils to maintain indoor comfort and support ventilation systems.

Standard steam coils are also used in makeup air units to temper incoming air before it enters occupied spaces. Their ability to deliver consistent heat output makes them suitable for applications requiring controlled air temperatures for both comfort and process conditions. Precision Coils manufactures steam coils for a wide range of commercial and industrial HVAC applications.

Benefits of Standard Steam Coils

Cost Effective: Simple construction can make standard steam coils an economical solution in appropriate applications.
Efficient Heat: Steam heating coils rapidly increase air temperature for process heating or to provide more comfortable temperatures.
Versatility: Replacement steam coils can be constructed in various sizes and configurations to integrate with multiple types of HVAC systems.
Low Maintenance: Steam coils utilize fewer components, resulting in easier cleaning and maintenance compared to more specialized coils.

If you need replacement, OEM, or design-build standard steam coils, Precision Coils offers expert construction with fast, exceptional service. Our decades of experience in manufacturing heat transfer products ensure our steam coils are constructed using optimal materials and match the airflow and pressure of your HVAC system for effective condensate drainage.

When to Use Standard vs. Non-Freeze Coils

Standard steam coils are used in applications where freezing conditions are not present or where systems are protected from low ambient temperatures. In these environments, single-pass coil construction provides efficient heat transfer and straightforward system design.

For applications where freezing conditions may occur, a steam-distributing coil or non-freeze coil design may be required. Precision Coils works with customers to determine the appropriate coil type based on operating conditions, system design, and environmental factors.
