Note: Always question non-approved units used on electrical enclosures to assure that your panels are not damaged by inferior products.

 

 

Nex Flow™ offers a High Temperature Warning Sticker free with every Frigid-X Panel Cooler  purchased for the air conditioning of electrical and electronic control panels.  High temperature inside a control panel can be damaging to internal equipment and lead to unplanned shutdown of factory operations.  The label provides for an effective  warning with a color change indicator to ORANGE and a danger warning with  a color change indicator to RED.  Color change is reversible so when the temperature problem is corrected, the label can continue to be used indefinitely.  While it is a qualitative measurement only, it provides an ideal cautionary monitoring of possible temperature problems within a control panel.

    How Cabinet Panel Coolers Work :

    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 exhausting air.

    ** In 316 environments normally customers will have special filtration systems for such environments already.

     

    *Cooling effect based on 95°F temperature inside cabinet, 100 PSIG (6.9 BAR) compressor inlet pressure, and 70°F (21°C) inlet temperature.

    BTU/hr. figures rounded to nearest 100 BTU/hr (1 WATT).

    All Continuous Operation models include the cooling unit, filter with auto drain and cold air distribution kit.

    All On-Off control units include the cooling unit, filter with auto drain, cold air distribution kit, solenoid valve and thermostat.

    SELECTION

    Cabinet enclosure coolers come with a 5 micron filter with an automatic drain (except for the 316L stainless steel units) for the compressed air supply to insure clean, dry air and an air distribution kit to circulate the cold air inside the enclosure for even cooling.

    Cabinet enclosure 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 energy.

    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 site.

    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 (except or the 316L stainless units). Panel Coolers must be mounted vertical either at the top or at the side using the side mount.

    Options

    Frigid-X™ By-Pass System for Panel

    In very dirty environments, it can be advantageous to have a small amount of compressed air entering the control panel when the panel cooler is not operating (turned off utilizing a solenoid and thermostat package to conserve energy).  This is a "constant purge" system that will keep the control panel at a  slightly positive pressure all the time to prevent dirty environmental air from entering, thereby keeping the control panel clean.

    Muffling Kits For Cabinet Panel Coolers

    In many environments where the surroundings are very quiet or if personnel are working next to control panels, the Hot End and Cold End Muffing kits can reduce the noise levels an additional 8 dBA depending on air capacity used!

    Electronic Temperature Control

    Electronic Thermostat ELC (Electronic Control Digital Thermostat) is a way for precise control of one or two Nex Flow™ Frigid-X™ cabinet panel coolers.

    Mechanical Thermostat And Solenoid Valve Kit

    This kit comes complete with a solenoid valve, thermostat, and a resistor. The resistor is included should you encounter rapid temperature fluctuations in the control panel causing the solenoid to cycle on and off to quickly (chattering). The resistor is installed (if needed) across the leads of the thermostat and prevents chattering by dampening the thermo switch sensitivity.

    Side Mount Kit for Cabinet Panel Coolers

    If mounting cannot be on the top of the control panel an optional Side Mount Kit for Cabinet Panel Coolers is available (except for the 316L stainless units). Enclosure Cooling System must be mounted vertical either at the top or at the side using the side mount.

    Calculating Head Load

    Total heat load consists of the heat transfer from outside your panel and from the heat dissipated inside the control unit.

    Useful terms and conversions:

    1 BTU/hr = 0.293 watts
    1 BTU/hr - 0.000393 horsepower
    1 Watt = 3.415 BTU/hr
    1 horsepower = 2544 BTU/hr
    1 Watt = 0.00134 horsepower
    1 Square Foot = 0.0929 square meters
    1 Square Meter = 10.76 square foot

    Typical fan capacity:

    4" fan: 100 CFM (2832 LPM)
    6" fan: 220 CFM (6230 LPM)
    8" fan: 340 CFM (9628 LPM)
    10" fan 550 CFM (15574 LPM)

    BTU/hr. cooling effect from fan 1.08 x (temp. inside panel in °F - temp. outside panel in degrees F) x CFM.

    Watts cooling effect from fan: 0.16 x (temp. inside panel in °C - temp. outside panel in degrees C) x LPM.

    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 °F BTU/hr./sq. ft. Temperature Difference in °C Watts/sq.m

    10 3.3 6 11.3
    15 5.1 9 17.6
    20 7.1 12 24.4
    25 9.1 15 31.4
    30 11.3 18 39.5
    35 13.8 21 47.7
    40 16.2 24 55.6

    Example:

    The control panel coolers has two frequency drives totaling 10 horsepower and one module rated at 100 watts. The maximum outside temperature expected is 105°F or 40.5°C. 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 95° or 35°C.

    Total internal power is 10 hp x 746 watts/hp - 7460 plus 100 watts = 7560 watts.
    Assume 10% forms heat = an internal heat load of 756 watts.

    Or

    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 10°F or 5.5°C. 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).
