Air Pre Heater

ATE  can design, engineer and manufacture tubular air pre-heaters, typically used for combustion air pre-heating.  Rigorously engineered, the air pre-heaters are custom designed for your plant layout.  We can handle very high gas temperatures, up to 1,750° F with our refractory lined units.

Precoolers are evaporative cooling modules that are used specifically to precool air  that is used to cool equipment such as heat exchangers, etc..  Perhaps the best example of how a precooler is used is the conventional air conditioner condenser coil.

This coil is used to dissipate heat to the outside air during the cooling cycle of the air conditioner.  Without precooling, the condenser coil uses outside air to dissipate the heat.  If that heat is 120 degrees (f) then the efficiency of the heat transfer is greatly reduced.  With precooling, the 120 degree (f) air temperature is reduced to about 90 degrees (f) which greatly improves the efficiency of the heat transfer of the condenser coil.  

At lower temperatures across the condenser coil, the air conditioner efficiency improves, the energy use is reduced and the compressor useful life is increased.  The air conditioner produces colder air at a lower energy cost.

Precoolers save energy costs, improve efficiency of the equipment being precooled and extends useful lifetime of the equipment.
