Steam Coil Air Preheaters

Steam Coil Air Pre Heater (SCAPH) is an extended surface type [finned tube] gas to the gas heat exchanger.
This equipment preheats air to the required process temperature using saturated steam.
Steam coil air preheaters (SCAPHS) are also used to heat air to raise the cold end temperature to prevent acid dew point corrosion.
In areas with low ambient air temperatures, this equipment is incorporated into the design of a boiler for low load operation and startup operation
This  air heater uses an extended surface, normally referred to as fins, to increase the heat transfer rate and to reduce the overall size
Finned tubes may be of a G-type or spiral wound and made of aluminium.
Our SCAPH’s are modular units that can be easily erected and removed from an existing location for maintenance activities.
