PERFORMANCE:
Depending on the available heat in the water at depth, ICE-AWAY deicer’s placed at 5’ feet / 1.53 meters of propeller depth will permit approximately 40’ feet / 12.20 meters of open water.
ICE-AWAY will permit 8’ feet /2.438 meters per foot
/ meter of propeller depth based on empirical data gathered over 40 years.
ICE-AWAY®
is the answer if you are a multi-slip marina operator,
individual boat / dock owner or someone concerned about water fowl and aqua-life
and your facilities are susceptible to freezing temperatures it is requisite to
understand the process of ice prevention or melting ice that has already formed
and the differences between the different types of ice melting devices.
There are two commonly accepted methods of ice prevention or
dissolution, namely compressed and diffused air or the use of mechanical
de-icing means such as a pump or an electric motor operated propeller. It is
important to recognize that it is not the
movement of water that prevents or melts ice per se’. Rivers and waterfalls
can freeze. Ice prevention or remediation is mainly dependent on how warm the
water is at depth within the area that is selected to be kept open and just how
rapidly that water is propelled to the surface.
The lower the velocity at which
the warmer subsurface water is propelled to the surface the more opportunity
there will be for the warmer subsurface water to dissipate its entrained heat to
the surrounding water and thereby loses some of the effective de-icing
capability. The ICE-AWAY®
pumps water at twice speed than that of competitive
deicing equipment. It is also necessary to recognize that the longer
that a body of water is exposed to freezing temperatures there will be a reduced
effect from any ice melting device. All of the deicing systems discussed here
require usable heat within the water to keep a given area open.
It is requisite to understand
that a “De-Icer” does not add heat to the water.
An example would be Lake Superior’s water temperature was measured at Bayfield, WI one particular winter and was found to have a temperature differential of only 0.3° Fahrenheit (-17.61°C) above the freezing point of (32°F (0°C) fresh water) 100' feet (30.48 m) down. Ice melting in this area while occurring, was minimal at 15’-20’ feet (4.572 m - 6.09 m) The air temperature was measured well below 0º F (-18°C).
During the same winter
in Lake Mead, NV / AZ there were water temperatures measuring 34˚F (1.11°C) at the same
depth as above. ICE-AWAY® had created an opened
area of 75’ feet (22.86 m). The air temperature was well
below 0ºF.
The warmer water temperatures in Lake Mead permitted larger
areas of open water than did the colder water of Lake Superior.
ICE-AWAY implements the use of a weedless, trail-back design propeller that moves 500 GPM, connected directly to the motor shaft.
