Delivers high capacity in a small surface area
The condensing heat of steam is far higher than that of water/glycol; the same air-heating capacity can be reached with less surface area.

Steam Coils
The finned tube element of high-capacity heating applications, transferring the latent heat steam gives up as it condenses into air. Correctly designed condensate drainage and freeze protection deliver high efficiency and a long service life.

Why it matters
What does a steam coil do?
As it condenses, steam gives up far more heat than water/glycol. A steam coil transfers this latent heat into air, delivering high-capacity heating.
The natural choice for facilities with a steam boiler
In boiler rooms producing process steam, air heating can be fed directly from the same steam line, with no need to build a separate water circuit.
Energy recovery through condensate drainage
Condensed steam (condensate) can be drained through a steam trap and returned to the boiler room, saving both fuel and water.
Can be specially designed against freezing
In systems exposed to outside air, the risk of condensate freezing is addressed in advance with a non-freeze circuit design and automatic drainage.
Types
Sub-types of steam coils
All three run on steam; what sets them apart is the need for freeze protection and the operating pressure.
Standard steam coil
A standard type suited to a typical pressure range of 2-6 bar(g), used indoors or on lines with no risk of freezing.
- Steel tube / aluminum fin construction
- Designed together with a steam trap
- Common on indoor and process lines
Non-freeze design
A special circuit design that prevents condensate from freezing and bursting the tubes on lines in contact with outside air, where the steam supply can be interrupted.
- Essential on outside-air pre-heat lines
- Automatic drainage and low-temperature alarm options
- Higher cost than the standard type
High-pressure process steam coil
Built with thicker steel tube and connections rated for a high pressure class, for applications where the process needs more than 10 bar(g).
- High pressure and temperature resistance
- Suited to heavy process lines
- May require special material certification
Selection criteria
What data determines the right steam coil?
Capacity alone isn't enough. Once the six points below are clear, the choice narrows to a single model.
ParameterWhy it mattersWhat we need from you
Heating capacity
Air flow rate together with the inlet–outlet temperatures determines capacity. An undersized coil can't reach the target temperature.
kW and air flow rate (m³/h)
Steam pressure
Operating pressure determines the tube wall thickness, material class and steam trap selection.
Typically 2–10 bar(g)
Condensate drainage
The steam trap type and condensate line design ensure the condensed steam is removed efficiently.
Steam trap type + line diameter
Freezing risk
If there is contact with outside air, a non-freeze circuit design, automatic drainage and a low-temperature alarm need to be planned.
Yes / no + ambient temperature
Air flow rate and face velocity
Fin spacing and row count are optimized against face velocity. Getting it wrong causes either excess pressure loss or insufficient heat transfer.
m³/h and m/s
Connection size and mounting orientation
The entry clearance into the duct or unit casing, the connection size, and the mounting orientation (horizontal/vertical) need to be clear from the start.
DN sizes + mounting orientation

FAQ
Questions from the field
The questions we hear most often when quoting steam coils.
Why is a steam trap needed in a steam coil?
As steam gives up its heat and condenses, it turns into condensate. A steam trap prevents condensate from accumulating inside the coil, draining off only the condensed water while keeping live steam from escaping.
Is there a risk of freezing in a steam coil?
Yes, especially in systems exposed to outside air where the steam supply can be interrupted — condensate can freeze and burst the tubes. A non-freeze circuit design and automatic drainage are recommended against this risk.
Why is the tube material for a steam coil chosen differently?
Steam runs at a higher temperature and generally higher pressure than water/glycol. For this reason, thicker steel tube and steam-rated connection fittings are generally used.
What pressure is a steam coil used at?
Typical industrial applications run in the 2-10 bar(g) range; custom designs at higher pressure are also possible depending on process needs. The pressure class determines the tube wall thickness and the gasket/connection choice.
