Truck Sleeper 12-Volt DC Air Conditioning SystemsUSED THE MK3 FOR SLEEPING IN THE DRY DESERT PLUS HUMID AREAS:
I purchased a MK3 as a gift for my husband
who works in the tropics and outback desert areas of Australia.
I was optimistic that the dual cooler/air-conditioner would give
him some relief from the heat. He recently passed through the
Opal Mining Town of Coober Pedy where they build their homes underground
to beat the heat and the temperature there was 54 degrees Celsius
(130 Degrees Fahrenheit). He sleeps in the back canopy area of
a utility while on the road working and he tells me THE MK3 IS
FANTASTIC! On the low setting it cools the sleeping area (using
water only) and he has no trouble sleeping at all. With ice (in
the Humid Tropics) and on a higher setting he pulled a sleeping
bag over himself because he was too cool! I want to thank you
for a great product and tremendous customer service. My husband
has recommended you to other drivers and they will be in touch
with you soon. TOO COOL! K.R. Blackwall Australia
THE MW1 COOLS USING WATER ONLY IN DRY CLIMATES:
Last night, I arrived in Mesquite, NV at 7 PM. The temp was 109.
Great time to try out the cooler (MW1), I set it in the back seat
area, next to the rear passenger window, opened the window about
4 inches and opened the drivers window about an inch, within a
couple of minutes the air in the cab started cooling off. It worked
great. I climbed into the sleeper about 10 PM and directed the
cooler toward me, it again worked great, kept me cool long enough
for the outside air to cool down to a comfortable sleeping temp.
Right now, I'm in Hesperia, CA. with the temp at 92 and the cooler
is keeping me comfortable while I'm sending you this information.
Great unit, thanks, B. K. Henderson, CO.

The two cooling models preferred by truckers are the MW1 model using water only in the dry areas.
The dual system MK3 model uses ice water
in humid areas or water only in dry areas. You can also use reusable
ice packs to help cool water, which will not duplicate ice, however
the MK3 will produce cooler air than water alone because of it's
Dual Cooling System.
Delivered Prices
range from $321.00 for the MW1 and $579.00 for the MK3 in the
Continental USA including selected options. (The MK3 uses the
energy of 4 clearance lights and the MW1 uses the energy of 1
clearance light.)
The Dual Cooling System of the MK3 contains a copper heat exchanger
with multitudes of openings for the ice water to pass, which produces
Air Conditioned air just like the heat exchanger (evaporator)
in your truck a/c. Then when using water only the MK3 produces
cool air by bringing the hot air through the Custom Evaporative
Filter, just like the MW1. This unique design produces cool air
automatically two ways with no adjustments needed.
If you drew a line through the middle of North Dakota continuing
south into the Gulf you would typically cool with water only West
of the line in dry areas or ice & water East of the line in
humid areas for comfort. Of course you may use water only in humid
areas if you would be satisfied with 10 or 15 degree cooler air
than a fan would produce.
Both models are dependable & rugged with only one $6 filter
to replace every 200 to 400 hours. The MK3 pump may need replacing
after 1,500 hours, which costs less than $20 at boat stores. The
blowers fans are 20,000-hour motors and should never need replacing.
Specifications including

The MK3 was designed for surveillance two years ago to keep the
back half of a van cool for up to 8 hours at a time. Now the MK3
is used in trucks & aircraft for cooling & uses no more
battery energy than four truck clearance lights.
The MW1 & MK3 are very efficient in dry climates producing
20 to 30 degrees cooler air than ambient temperatures using water
only. You need Ventilation to keep from building up any excess
humidity. In humid climates the MW1 & MK3 may cool about 10
to 15 degrees cooler than a fan however does nothing to reduce
humidity plus ventilation is important.
The method the MW1 and the MK3 use for cooling with water only
is more effective than normal evaporative cooling because of a
unique Custom evaporative filter that wicks water as it needs
it for perfect evaporation. When it is real dry they wick more
water and when humid wicks less water, therefore always produces
cooler air than any other portable evaporative cooler.
In a humid area it is always easier to air condition by idling
or if available go to an idle air station than plan on the amount
of ice you need for several hours of use. Of course in a dry area
you do not need to idle or plan as you cool with water only when
you have a MK3.
If you want air conditioning and cannot idle in a humid area as
you are loading or unloading or stuck in the boonies the MK3 is
ready to provide what you need. You just plan on the number of
hours you need air conditioning and pick up the ice needed at
Wal-Mart, Target, Truck Stop, etc.
A negative to air-conditioning in a humid area with the MK3 is
planning for the amount of time you need cooling just like they
do when performing surveillance. Also the cost of ice could be
$2.00 to $2.50 for every hour you need cooling as you may use
from 10 to 12 pounds of ice per hour at night & more in the
daytime.
Of course your investment in the MK3 and ice could be well worth
it for the times you are over heated in a humid or dry area. Remember
when in dry climates or even stuck in a humid area without ice
you still benefit from cooling with just water. You can also use
reusable ice packs to help cool water, which will not duplicate
ice, however will produce cooler air than water alone.
Along with the MK3 you need an ice chest and a cigarette lighter
plug in your truck. The ice chest could cost $20.00 or $30.00
and be of various sizes depending on your need for air conditioning
in a humid area. For example a 50 quart ice chest could be 19"
x 19" x 19" and provide up to 6 hours of sleep using
ice at night. The MW1 is self contained with only an optional
$12.00 collapsible water kit suggested.
There are two small 5/8* water hoses pumping water in and out
of the MK3. One of which contains a pump that forces 300 gallons
of water every hour through the Copper evaporator. The other returns
the water back into the ice chest siphoning condensation with
it creating a dry closed system. If you are interested to learn
more about this type of Air Conditioner that uses Ice Water Click Here .
The MK3 20,000-hour fan motors produce cold air by flowing the
hot and humid ambient air through the ice chilled copper evaporator
producing the cold air into the area you need air conditioned.
When you need to eliminate excess water from the ice chest, merely
take the return line and put it out the door, turn on the MK3
and it will pump out the water in a minute or two. Therefore you
never need to move or remove your ice chest.

I
just want to tell you that doing business with you has been great
and that the customer service has been excellent. The unit works
great I am a truck driver works for Knights Transportation out
of Phoenix,AZ and at times have to sleep in my truck in Phoenix
when the outside temp is still over 100 and all I do is open the
2 top sleeper vents for fresh air and turn the unit on high and
can sleep all night without wakeing up. I have told other drivers
about it and showed them how good it works and they say they going
to order one for themselfs. Thank you. C. G. Tuscson, AZ.
My husband did have a chance to use his (MW1) this last week in
California. The temperature was into the nineties in the daytime
and he was able to sleep in the sleeper with his Swampy running.
He is very pleased with this purchase. Thanks, M.A. Battle Mountain,

Just to let you know
I am a local truck driver here in the valley and my company like
many out there nowadays don't want us to idle when we get stuck
somewhere waiting to get loaded or unloaded. Well today I got
stuck sitting at one of the shippers over in Tolleson for about
4 hours and while my buddies in the trucks be side me were cookin'
I was comfortable thanks to my MW1. Thanks for a great product!
M.H. Black Canyon City, AZ
T.D. of Atlanta, GA. called 06/03/2008 to
order additional cooling filters as she purchased a MW1 for her
husband for his truck Sleeper in 2005. When she ordered the MW1
we explained that this type of cooling was not as effective in
a humid area as it is in a dry area. She ordered it anyway and
her husband says it blows cool air while he sleeps plus has saved
a lot of Fuel these past two years. (Other) -[Testimonials]
One gallon (3.75 liters) of water will last around two
to three hours in the daytime and four to five hours during the
night when used for evaporative cooling in dry desert climates.
The "Ice Water" models are capable of using up to 20
pounds (9.0 kilograms) of ice per hour during the day and up to
13 pounds (5.9 kilograms) at night.
The MW1 operates for 50 to 80 hours on one battery and the MK3
will operate for 25 to 35 hours on a single battery before needing
charging.
