| Heated Wash - In Action, Tests, and Comparisons |
| This video clip shows the performance of heated wash for frost removal. Conditions: Temperature 0°F. As you can see 4 sprays is typically enough to clean a frosted windshield |

| Comparison test of frost removal: OEM-GM vs. AT-37GM |
This video clip shows the comparison between
AT-37GM and OEM-GM units
Conditions: Temperature 0°F.
As you can see from the comparison, AlphaTherm
slightly outperformed OEM-GM unit

| Comparison test of Heated Wash vs Heated Windshield |
This Video clip shows how Heated Wash compares to a
Heated Windshield offered by some automakers on their
luxury vehicles
Conditions: Temperature 0°F.
The Heated Windshield was turned on at the beginning of
the test. The result was astonishing, the Heated Wash
outperformed the Heated Windshield by 13 minutes.

All cold tests were provided according to SAE (Society of Automotive Engineers) test procedure. Vehicles were soaked in cold chamber
for 8 hours at 2°F. The frost was created with quantity of water equal to 460ml per 1sq/meter. Spray intervals for Heated Wash were
predetermined. The Heated Wash performance may vary based on vehicle and temperature conditions.

Heated Wash can improve the spray of washer nozzles by clearing particles of dirt or ice from the system.
Most vehicles today use fluidic spray nozzles in the wash/wipe system. These nozzles are designed to
oscillate the fluid to produce large fan type coverage on the windshield for superior cleaning. However, in cold
temperatures the washer fluid thickens and this can produce a weak jet type spray.

Ice and frost are formed by moister turning into crystals. As these crystals
form on your vehicles windshield they create thousands of sharp edges
that can be damaging to rubber wiper blades as they are dragged across
them. However, as heated fluid starts to melt the ice, the sharp edges are
reduced. This prevents wiper blade damage and prolongs life.
