Coil de chauffage à vapeur

A framed finned-tube coil that condenses plant steam inside its tubes to provide high-capacity cleanroom air heating.

Introduction de produit

Steam enters a distribution header and flows through copper tubes surrounded by aluminum fins. As steam condenses, latent heat transfers rapidly to the air crossing the fin face and condensate exits through a lower return connection. Correct tube pitch, casing orientation and venting support drainage at part load, while a non-freeze steam-distributing pattern can be selected for cold outdoor-air duty.

Key Features

Latent heat of condensation provides substantial air-temperature rise in a compact one- or two-row coil.

A properly sized steam header distributes vapor across the tube bank instead of concentrating flow at one circuit.

Lower condensate connections and pitched tubes reduce retained water and waterhammer risk.

Removable casing panels expose tube returns, vents and trap connections for inspection.

Préoccupations du client produit

Steam coils need uniform distribution and unrestricted condensate removal to avoid noise, erosion and freeze damage.

Condensate pools in tubes during low-load operation.Pitched circuits and a low condensate header establish positive drainage to the steam trap.

Cold outdoor air freezes retained condensate in inactive tubes.A steam-distributing tube arrangement keeps vapor moving through the active heating tube.

Wet steam erodes the inlet header and creates noisy operation.Upstream separation and correctly sized header entry deliver dry steam at controlled velocity.

Dirty fins restrict airflow and reduce leaving temperature.Accessible wide fin spacing and removable face guards support careful coil cleaning.
