Air heat exchangers are shoebox-shaped pressure vessels that circulate fluid with the force of ambient, or outdoor, air around filters or tubes with finned features. With finned filters or tubes as barriers, air heat exchangers process using fluids such as water, fused salts, mercury or steam. Common types include air to air heat exchangers, which filter clean air during processing, and water to air heat exchangers, which use water for heating and cooling processes. Air heat exchangers are made from stainless steel, brass or copper, and in addition to heating and air conditioning, they also function for facility ventilation and refrigeration.

Common examples of air heat exchangers include engine radiators, combustion preheaters, steam condensers and turbine lube oil coolers. Pick a shoebox-sized heat exchanger for home cooling or office use, or an industrial heat exchanger for power plant applications. Air heat exchangers can be a useful part of your business if you're in the petrochemical or petroleum industries. You may also need industrial heat exchangers if you can or process foods.

1. Find air heat exchangers suitable for industrial, commercial or home use.

2. Buy air heat exchanger accessories that improve efficiency.

3. Seek air heat exchangers that meet safety standards.

Tips & Tactics
Helpful advice for making the most of this Guide

• Most air heat exchangers are green, or environmentally safe to use in the home or factory. Air heat exchanger suppliers offer units that operate at 13, 35 and 100 watts for energy efficiency.
• The fluid barrier of an air heat exchanger, also known as the finned tube pipe or filter, is usually made from a metal plate, plastic or graphite. These materials work best because they resist corrosion.
