Frigid-X Silent X-Stream Cabinet Panel Coolers And Cabinet Enclosure Coolers
Silent X-Stream Cabinet Panel Coolers And
Cabinet Enclosure Coolers for electronic control
panels provide a low cost method of both purging
and cooling electrical and electronic control panels
by using a stainless steel vortex tube to create
cold air from ordinary compressed air. Utilizing
a hot and cold end muffling kit the unit is made
extra quite to under 64 dBA depending on capacity.
The hot end muffler also acts a heat guard
you can actually wrap your hand around it
without feeling much heat. The hot air is exhausted
safely underneath the hot end muffler.
Frigid-X Silent X-Stream Cabinet Panel
Coolers And Cabinet Enclosure Coolers are compact
and can be installed in minutes through a standard
electrical knockout. There are virtually no moving
There are Three (3) Types of Cabinet Panel Coolers to choose from:
NEMA Type 12 For Electronic Control Panels for General use in industrial environments where no direct liquid spray is applied to the unit. Stainless steel construction to hold up in corrosive environments.
NEMA Type 3R For Electronic Control Panels for Outdoor Use. Stainless steel to hold up to rain, snow, humidity and general outdoor use.
NEMA Type 4-4X For Electronic Control Panels - splash resistant, for use in wash down environments as well as outdoor use. Unique patent pending design for secure water tight protection. Stainless steel for food service and corrosive environments. Stainless steel also provides for long life in wet environments and for outdoor use.

Filtered, compressed air enters the cabinet enclosure cooler and through
the vortex tube component. The air is split into two
streams, one hot and one cold.
The muffled hot air from the vortex tube is expelled through the top of the
air conditioner through a secondary hot end muffler
attachment. The cold air is directed into the enclosure
through a cold end muffling kit and then into the
cold air distribution hose. Hot air inside the enclosure
rises and exits to atmosphere via the air exhaust
at a slight positive pressure. The enclosure is both
purged and cooled with clean air. No outside air enters

Units applicable to all environments including high temperature to 200ºF
Compressed air enters at point (A) into the vortex
tube component of the panel cooler. The vortex tube
splits the compressed air into a hot (B) and cold
(C) stream of air. The hot air from the vortex tube
is vented to the atmosphere at point (D) after being
muffled to reduce noise. Hot air displaced from inside
the control panel cooler or cabinet enclosure cooler
is exhausted through point (E). Cold air enters into
the panel (F) via the cold distribution hose (G).
Holes (H) are punched into the hose kit to deliver
the cold air inside the panel cooler where required.
A muffler (I) further reduces the noise level of the

Enclosure Coolers come with a 5 micron filter with
an automatic drain for the compressed air supply to
insure clean, dry air and an air distribution kit
to circulate the cold air inside the enclosure for

Coolers are available with or without thermostat control.
When constant cooling and a constant positive purge is required we recommend
the continuous operating version without the thermostat
and solenoid valve. The cooling effect can be controlled
by adding a regulator in line to reduce pressure for
reduced cooling when it is not required and to conserve
Systems utilizing a thermostat and solenoid valve saves air by activating
the air conditioner only when the internal temperature
reaches a critical level. The adjustable thermostat
is factory set at 95°F but can be readjusted on
Thermostat and solenoid valve systems are recommended where the heat load
can fluctuate (such as for frequency drives) and where
a continual purge is not required. The thermostat
and solenoid "package" can also be added
at a later date to a continuous system. An Electronic
Thermostat System is also available replacing the
thermostat and solenoid valve with a control box to
set the temperature (ELC System).
If mounting cannot be on the top of the control panel an optional side mount is available Panel Coolers must be mounted vertical either at the top or at the side using the side mount. NOTE: If using the Side Mount you cannot utilize the Hot End Muffler but you can still use the Cold End Muffler.
Cabinet Panel Coolers can provide a cooler master cabinet which may have smaller enclosures inside.
There are many panel coolers manufactures which are normally air conditioners, heat exchangers, fans or other vortex cooler systems.
to Cool Electrical Enclosures:
Electrical Enclosures or cabinets can be cooled several ways. They may be cooled by fans, water-cooled systems, heat pipe heat exchangers and air conditioners. Each system has potential limitations in cooling, or maintenance costs or can be affected by the ambient air. The Panel Coolers however is virtually maintenance free.
Electronic Temperature Control is available for the Silent X-Stream Frigid-X Panel Cooler.
The Adjustable Thermostat provided with our Panel Cooler for on-off control is preset but is also an Adjustable Thermostat to reset the temperatures if desired.

Watts cooling effect from fan: 0.16 x (temp. inside

Calculating BTU/hr. or Watts:
Determine the heat generated inside the enclosure.
Approximations may be necessary. For example, if you
know the power generated inside the unit, assume 10%
of the energy is dissipated as heat.
For heat transfer from the outside, calculate the
area exposed to the atmosphere except for the top
of the control panel.
Choose the internal temperature you wish to have,
and choose the temperature difference between it and
the maximum external temperature expected.
From the conversion table that follows, determine
the BTU/hr. per square foot (or watts per square meter)
for the temperature difference.
Multiply the panel surface area times the BTU/hr.
per square foot (or watts per square meter) to get
the external heat transfer in BTU/hr or in watts.
Sum the internal and external heat loads calculated.
If you do not know the power used in the enclosure
but you can measure temperatures, then measure the
temperature difference between the outside at current
temperature, and the present internal cabinet temperature.
Note size and number of any external fans. Provide
this information to Nex Flow to assist in sizing
the appropriate cooling system.
Temperature Difference in ºF
Temperature Difference in ºC
The control panel coolers has two frequency drives totaling 10 horsepower
and one module rated at 100 watts. The maximum outside
temperature expected is 105ºF or 40.5ºC.
The area of the control panel cooler exposed sides,
except for the top is 42 square feet or 3.9 square
meters. We want the internal temperature to be 95ºF
Total internal power is 10 hp x 746 watts/hp - 7460 plus 100 watts = 7560
Assume 10% forms heat = an internal heat load of 756
Total internal power is 10 hp x 2544 BTU/hp = 25440 BTU/hr plus 100 watts
x 3.415 BTU/hr/watt = 25782 BTU/hr.
Assume 10% forms heat = an internal heat load of 2578 BTU/hr.
External heat load: The temperature difference between the desired temperature and the outside is 10ºF or 5.5ºC. Using the conversions (and interpolating where necessary) we multiply the area by the conversion factor:
42 sq. ft x 3.3 - 139 BTU/hr or 3.9 sq. m x 10.3
= 40 watts
Total Heat Load: 756 + 40 - 796 watts or 2578 + 139
- 2717 BTU/hr.
You would use a Model 61040 for constant operation
or a Model 63040 for one-off control. (Rated at 2900
BTU/hr or 849 watts).
