GenSalt – Salt Spray Tester

The precision adjustment is the second of the two pressure stages in the GenSalt air supply. After the incoming air has been roughly regulated, this stage sets the spray pressure to 1 kg/cm² (14.2 psi), read on a 1/4 pressure gauge.

The gauge reads the air after it has passed through the saturated air barrel, just before it reaches the nozzle, so the operator sees the pressure the nozzle actually works at. Our test procedure keeps it at 1.00 ± 0.01 kgf/cm² for the whole run.

That pressure drives the atomization, so a steady setting keeps the fog and the collected spray volume consistent over a long test. Our manual also warns against going above the specified pressure, because excess pressure can damage internal components.

The fog conditions involved are described on our ASTM B117 page.

Exterior dimensions, width by depth by height, are 42.1 x 23.6 x 46.5 in (107 x 60 x 118 cm) for the GenSalt-60, 55.1 x 35.4 x 51.2 in (140 x 90 x 130 cm) for the GenSalt-90 and 74.8 x 43.3 x 55.1 in (190 x 110 x 140 cm) for the GenSalt-120.

The three models hold the same test climate and differ in chamber size and footprint, so the choice comes down to the parts you load and the floor space you have.

Plan more room than the cabinet itself. Our operation manual places the machine about 20 in (50 cm) from the wall, with space on both sides for maintenance. The exhaust needs a straight, unobstructed run to the outside, and the drain line has to slope downward.

If your lab layout is tight, send the floor plan through our contact page and we will check the fit.

Specimens rest on a sample placing anvil made from temperature-resistant ABS plate 8 mm thick, developed for high weight support.

For loading, our operation manual rates the sample shelf at 2 kg (4.4 lb) for a load concentrated at one point and up to 10 kg (22 lb) when the load is spread out, so heavier parts should be distributed across the shelf rather than stacked in one place.

Flat panels are held at an angle. Rows of holes on both sides of the rack take bars at 15° or 30° from the vertical, and our procedure gives 150 x 70 mm and 100 x 65 mm as standard test piece sizes.

Load the specimens once the chamber and the saturated air barrel have reached temperature, using both rack levels, and close the lid before the spray starts.

The GenSalt heats with a pure titanium heating tube, which resists acid and alkali corrosion and has a long service life in the salt atmosphere of the chamber.

The tube is U-shaped and sits in a heating sink below the chamber. The water in that sink both heats the chamber and insulates it, which keeps the test temperature stable, and the fast heating rate shortens the wait before a test can start.

Looking after it is simple. If a test runs longer than one month, replace the water in the heated tank to keep heating performance up. If the next test is a long way off, drain the heating sink after the current one and clean the chamber.
