Aircooled Type of Header

WELDED BONNET HEADER COVER PLATE HEADER
The Welded bonnet type is used to in some cases for special services as ammonia condensers, freon condensers and vacuum condensers. One disadvantages consists in the difficult access to the inside of the tubes in case of leakage of fouling. The Cover plate header is used for fluids with fouling factors when a frequent mechanical cleaning is necessary it is used also for very corrosive process fluids so as to periodically check the corrosion allowance.
PLUG HEADER MANIFOLD HEADER
The Plug header is the most commonly used up to 200 bar working pressure. The Plug hole opposite each tube allows expansion of the tube in the tube sheet, mechanical cleaning, and plugging in case of leakage. Seal welding or strength welding can be provided for high partial hydrogen pressure services solutoin than the use of pipe headers generally used for over 200 bar service pressure. A Large circular manifold is used in some cases when the allowable pressure drop is very low. This large manifold ensures an equal distribution of fluid flow in the tubes. The tube sheets are directly welded to the manifold. This type is used for vacuum steam condensers and refigeration units.
PIPE HEADER
The pipe headers are used for working pressures over 200 bars. U-bend tubes are welded to the weldolets on the pipe. The welds are heat treated and X-ray tested.
FIN TYPES

Aircooled Type

Induced Draft Unit Forced Draft Unit
The Induced draft unit gives a steady and durable thermal performance due to the protection of the finned surface against wind, rain and snow by the plenum chamber. The induced draft also ensures a better air distribution, less fouling and lower noice levels at grade. The forced draft unit allows an easy access for maintenance to the fans and to the bundles. Furthermore, the fans remain in the cold ambient air.
Humified Air Cooler Forced Draft Unit
The combination of aircooler and humidification sections is a good solution in some dry areas and hot climates. The ambient air is cooled by humidification at the inlet of finned tube bundles.
