NorthWind Portable Air Conditioners
Expect the unexpected. Whether you are
describing a high tech computer server room servicing Fortune 500
companies, a massive white tent containing hundreds of people at an
outdoor charity event in July heat or the sand fields of Iraq in
the midst of a war zone, portable air conditioners are a crucial
piece of equipment that must be built for the unexpected.
Portable cooling equipment designed to exceed the rigors of
temporary and unpredictable rental market applications must be
manufactured to be extremely adaptable, rugged and to deliver 100%
continuous duty. Just position a portable air conditioning
unit where it's needed, plug it in, and turn the thermostat to the
desired cooling.
Everything in life should be that simple.
For NorthWind, Incorporated's state-of-the-art line of Tundra
portable air conditioners, cold air is that simple and easy to
maintain. It doesn't matter if the problem is space cooling,
process cooling, spot cooling or people cooling; their unit
effectively cools commercial and industrial spaces with an
operating range from 50°F to 115°+F at virtually any humidity
level. North Wind designed the Tundra series around a powerfully
unique, 2-speed external rotor, forward curved blower dynamically
balanced in 2 planes, supplied by Rosenberg-Ecofit. This
blower system guarantees that optimal air can be delivered with
minimal noise and vibration. To accommodate the
powerful air movement created, each unit contains 2-4 air intakes,
depending on the unit size. Air movement
throughout the condensing components flows at a rate of
approximately 600 CFM per ton, which depending on the unit size can
be up to 4,500 CFM in a 7.5 ton unit. The unit's static pressure,
or the amount of air pressure created by the blower, can range from
.5" - 1.3" ESP. Air flow through the heat absorbing
evaporator blower flows at a rate of approximately 400 CFM per ton,
or up to 3,000 CFM in a NorthWind Kodiak series 7.5 ton unit.
Every NorthWind unit includes Permatron's
PreVent® electrostatic air filters to help reduce the amount of
dust being drawn into the condenser and evaporator air intakes no
matter what the application throws at them. Air intake
filters, upstream of each coil, are mandatory to protect the
aluminum 14 fins per inch coils that would normally clog up with
debris, and restrict air flow over critical components, forcing
systems to run longer cycles at reduced capacity and higher
temperatures. Sandwiched between a protective outer aluminum
grill and a wire filter retainer grid, PreVent is custom made, with
sonic welded edges keeping the filter smooth, flat, and
space-saving. In portable air conditioning, size
is important. The units must be designed to be compact,
and be able fit through a standard 32" wide
door. PreVent air intake filters are UV protected
polypropylene and stand up to extreme outdoor or indoor exposure,
corrosive environments, and high velocity air flow. Foam type
filters become brittle over time and lose their
effectiveness. Metal mesh filters are difficult to handle,
damage easily and need messy tackifiers in order to work.
North Wind's owners, Joe Pius and John Spencer, with their combined
70 years of air conditioning experience, both believe that
Permatron's PreVent filters stand up to the unmatched quality of
their units.
Recommended maintenance of these reusable air intake filters includes removing the easy lift out filter and frame assembly bi-weekly, and simply rinsing it clean with water versus hours of hand cleaning, power washing or using messy chemical solvents on the fins. The portable air conditioning rental market demands easy-to-operate and maintain equipment in any type of indoor or outdoor environment. PreVent's unique and versatile design helps portable cooling equipment meet this goal.
