Abstract
A system for draining an airfan heat exchanger includes an airfan heat exchanger including a housing, a pressurized gas source fluidly coupled to the airfan heat exchanger and configured to hold a purging gas at a predetermined pressure, and a controller configured to control delivery of the purging gas to the airfan heat exchanger. The pressurized gas source is configured to provide a flow of the purging gas to the airfan heat exchanger and thereby drain water held in the airfan heat exchanger. The purging gas to the airfan will cause the airfan to drain quickly avoiding potential damage to the airfan from freezing of the water during cold weather.
