Description
The Airfin Cooler provides a reliable means of reducing the temperature sur-
rounding a mechanical seal, without the use of cooling water.
There are three models of Airfin Coolers. The Model 625 NC operates by means
of natural convection. Hot air rises up through the center of the coiled tubing,
drawing cool air in from the sides and bottom. The two Model 625 FC units are
identical to the above model, except they are equipped with motor driven squirrel
cage type blower wheels.
1 Installation
1.1 All models must be mounted in a vertical position, adjacent to and above
the seal chamber. The piping, or tubing, to and from the Airfin Cooler
should be as short as possible. See Figure 1.

1.2 The Airfin Cooler should be mounted in a location where it will be free from
all obstructions on the top, bottom, and sides. Failure to do so will result in
an appreciable reduction in heat transfer efficiency.
1.3 Please read the complete instructions before starting installation. Be sure
you have a copy of the proper Airfin Cooler assembly drawing.
