CAI’s packaged Heat Recovery Units (HRU) provide the greatest fuel utilization by capturing waste heat to generate hot water or hot oil to serve process heating requirement. They provide accurate delivery temperature up to 750oF at virtually atmospheric pressure in process heating applications.

Compact, finned tube type gas to liquid heat exchanger with vertical or horizontal gas flow configuration provides ease of installation to suit site conditions. The easily accessible openings on the side panels provide ease of inspection and maintenance.

The thermal fluid flows through the HRU coil, eliminating the possibility of vapor lock or short circuiting the fluid. At all times, all equipment in the heating system, including the HRU and the process users, are exposed to atmospheric pressure via expansion tank. Therefore, the HRU tubes are not subjected to excessive pressure. The only pressure exerted on the HRU tubes is that required to move the liquid around. Pressurized systems are also available for special applications.

Typical HRU applications include process heating / cooling in the plant, Master process heating system to minimize fuel usage in other part of the plant, moisture removal system for fuel gas conditioning, Gas Turbine Recuperation System and Air Intake Cooling System.
