What is an EXAIR Cabinet Cooler System?
EXAIR Cabinet Coolers are a low cost, reliable way to cool and purge electronic control panels. They provide air conditioning for the electrical enclosures, eliminating electronic control downtime due to heat, dirt and moisture! These panel cooling systems for enclosures incorporate a vortex tube to produce cold air from compressed air - with no moving parts.
The compact Cabinet Cooler is an easy to use air conditioner that can be installed in minutes through a standard electrical knockout. NEMA 12, 4 and 4X Cabinet Coolers that match the NEMA rating of the enclosure are available in many cooling capacities for large and small control panels.
Why EXAIR Cabinet Coolers?
When the electronics inside a control cabinet overheat, the machine can shut down due to tripped overloads and breakers or heat damage to the circuit boards. Unreliable cooling methods such as fans, heat exchangers, refrigerant air conditioners, and heat pipes are prone to failure as a result of mechanical wear, and clogged filters.
EXAIR Cabinet Coolers provide cold air for large and small control panels and are maintenance free. They have no moving parts to wear out. All Cabinet Coolers are UL and ULC Listed and have a five year “Built To Last” warranty.
NEMA 4 (IP66) Cabinet Coolers
Cabinet Cooler systems are dust and oil tight, splash resistant and indoor/outdoor capable. By incorporating a low pressure valve for all air exhaust, the valve closes and seals when not operating to maintain NEMA 4 enclosure integrity.
Thermostat control systems (Models 4804-4880) are the most efficient system because it will turn itself on and off as needed to cool your enclosure. Includes cooler, solenoid valve and thermostat, filter separator and cold air distribution kit. Models are available in 110VAC, 240VAC and 24VDC.
Continuous operation systems (Models 4704-4780) include the cooler, a filter separator and cold air distribution kit.
ETC Thermostat control systems provide on the fly temperature adjustment and an internal temperature feedback display.
High Temperature Cabinet Cooler systems should be used when ambient temperatures reach 125°F to 200°F (52°C to 93°C).
Non-Hazardous Purge (NHP) models provide a continuous positive purge within the enclosure to prevent contaminants from entering. They are suited for extremely dirty and dusty environments.
Dual Cabinet Cooler systems (Models (##50-##80) provide for additional cooling.
Features
How Cabinet Coolers Work |
|
 |
|
Compressed air enters the vortex tube powered Cabinet Cooler and is converted into two streams, one hot and one cold. Hot air from the vortex tube is muffled and exhausted through the vortex tube exhaust. The cold air is discharged into the control cabinet through the cold air distribution kit. The displaced hot air in the cabinet rises and exhausts to atmosphere through the cabinet air exhaust at a slight positive pressure. Thus, the control cabinet is both cooled and purged with cool, clean air. Outside air is never allowed to enter the control panel. |

NHP NEMA 4 Cabinet Cooler Advantages
Features
Heat Can Stop Your Machines
It happens when you least expect it. High temperatures can cook the electronics that control your machines, resulting in erroneous readings, trip-outs or fried circuit boards. Cooling the electrical cabinet can eliminate these problems, but how will you do it?
Fans
Opening the panel door and aiming a fan at the circuit boards is a bad idea.
Heat Exchangers and Heat Pipes
These have serious limitations. On hot summer days when the temperatures of the room and inside the enclosure are about equal, there’s not enough difference for effective heat exchange.
Refrigerant Panel Air Conditioners
These coolers are prone to failure in dirty, industrial environments when dust and dirt clogs the filter.
EXAIR Cabinet Cooler Systems
EXAIR has a complete line of Cabinet Cooler Systems to dependably cool and purge your electrical enclosures. They convert an ordinary supply of compressed air into clean, cold 20ºF (-7°C) air. They mount in minutes through an ordinary electrical knockout and have no moving parts to wear out. Compressed air filtration is provided that keeps water, oil and other contaminants out of the enclosure.
Features
Selecting The Right Cabinet Cooler® System
With or Without Thermostat Control
EXAIR Cabinet Coolers are available with or without thermostat control. The continuous coolers (Model 4200 and 4700 series) are recommended when constant cooling and a constant positive purge are desirable. The thermostatically controlled systems (Model 4300 and 4800 series) save air by activating the cooler only when internal temperatures approach critical levels. The adjustable thermostat is factory set at 95°F (35°C). Thermostatic systems are recommended where heat load fluctuates and continual purge is not required.
All EXAIR Cabinet Cooler Systems contain a 5 micron Automatic Drain Filter for the compressed air supply and a Cold Air Distribution Kit to circulate the cold air throughout the enclosure.
Environmental Considerations
NEMA 12 (IP54) Cabinet Coolers (dust-tight, oil-tight) are ideal for general industrial environments where no liquids or corrosives are present.
NEMA 4 (IP66) Cabinet Coolers (dust-tight, oil-tight, splash resistant, indoor/outdoor service) incorporate a low pressure relief valve for both the vortex tube and cabinet air exhaust. This valve closes and seals when the cooler is not operating, to maintain the integrity of a NEMA 4 enclosure.
NEMA 4X (IP66) Cabinet Coolers (corrosion resistant) offer the same protection as NEMA 4, but are constructed of 304 stainless steel for food service, pharmaceutical and corrosive environments.

Determine Correct Model for Your Use
Sizing Guide - How to Calculate Heat Load for your Enclosure
To determine the correct model for your application, it is first necessary to determine the total heat load to which the control panel is subjected. This total heat load is the combination of two factors — heat dissipated within the enclosure and heat transfer from outside into the enclosure.
To Calculate Btu/hr.:
1. First, determine the approximate Watts of heat generated within the enclosure. Watts x 3.41 = Btu/hr.
2. Then, calculate outside heat transfer as follows:
a. Determine the area in square feet exposed to the air, ignoring the top of the cabinet.
b. Determine the temperature differential between maximum surrounding temperature and desired internal temperature. Then, using the Temperature Conversion Table (below), determine the Btu/hr./ft.2 for that differential. Multiplying the cabinet surface area times Btu/hr./ft.2 provides external heat transfer in Btu/hr.
3. Add internal and external heat loads for total heat load.
Temperature Conversion Table |
|
| Temperature Differential ° F | Btu/hr/ft.2 |
| 5 | 1.5 |
| 10 | 3.3 |
| 15 | 5.1 |
| 20 | 7.1 |
| 25 | 9.1 |
| 30 | 11.3 |
| 35 | 13.8 |
| 40 | 16.2 |
Example:Internal heat dissipation: 471 Watts or 1,606 Btu/hr. Cabinet area: 40 ft.2 Maximum outside temperature: 110°F Desired internal temperature: 95°F The conversion table (above) shows that a 15°F temperature differential inputs 5.1 Btu/hr./ft.2 40 ft.2 x 5.1 Btu/hr./ft.2 = 204 Btu/hr. external heat load. Therefore, 204 Btu/hr. external heat load plus 1,606 Btu/hr. internal heat load = 1,810 Btu/hr. total heat load or Btu/hr. refrigeration required to maintain desired temperature. In this example, the correct choice is a 2,000 Btu/hr. Cabinet Cooler System. Choose a Cabinet Cooler model by determining the NEMA rating of the enclosure (type of environment), and with or without thermostat control. |
To Calculate Kcal/hr.:
1. First, determine the approximate Watts of heat generated within the enclosure. Watts x .86 = Kcal/hr.
2. Then, calculate outside heat transfer as follows:
a. Determine the area in square meters exposed to the air, ignoring the top of the cabinet.
b. Determine the temperature differential between maximum surrounding temperature and desired internal temperature. Then, using the Metric Temperature Conversion Table (below), determine the Kcal/hr./m2 for that differential. Multiplying the cabinet surface area times Kcal/hr./m2 provides external heat transfer in Kcal/hr.
3. Add internal and external heat loads for total heat load.
Temperature Conversion Table (METRIC) |
|
| Temperature Differential ° C | Kcal/hr/m2 |
| 3 | 4.5 |
| 6 | 9.7 |
| 9 | 15.1 |
| 12 | 21.0 |
| 15 | 27.0 |
| 18 | 34.0 |
| 21 | 41.0 |
Example:Internal heat dissipation: 471 Watts or 405 Kcal/hr. Cabinet area: 3.7m2 Maximum outside temperature: 44°C Desired internal temperature: 35°C The conversion table (above) shows that a 9°C temperature differential inputs 15.1 Kcal/hr./m2. 3.7m2 x 15.1 Kcal/hr./m2 =56 Kcal/hr. external heat load. Therefore, 56 Kcal/hr. external heat load plus 405 Kcal/hr. internal heat load = 461 Kcal/hr. total heat load or Kcal/hr. refrigeration required to maintain desired temperature. In this example, the correct choice is a 504 Kcal/hr. Cabinet Cooler System. Choose a Cabinet Cooler model by determining the NEMA rating of the enclosure (type of environment), and with or without thermostat control. |

Other Considerations
Filtration:
EXAlR Cabinet Cooler Systems include a 5 micron automatic drain water and dirt filter. This filter is critical for protection of electronics from water in the compressed air line. If oil is present in the compressed air supply, the addition of a coalescing (oil removal) filter, such as EXAlR Model 9005, is recommended.
Cold Air Distribution Kit:
The kit includes a length of flexible vinyl tubing used to direct the cold air for circulation, or to hot spots. Tubing connectors and adhesive backed clips to hold the tubing in place are provided.
Humidity:
For a continuous operating Cabinet Cooler, relative humidity inside the enclosure stabilizes at 45%. No moisture condenses inside the enclosure. (The enclosure must be sealed to prevent condensation.)
Inlet Air Temperature:
Cabinet Cooler Systems provide a 50°F (28°C) temperature drop from supply air temperature when the inlet pressure is 80 PSIG (5.5 BAR). Elevated inlet temperature will produce a corresponding rise in cold air temperature and reduction in cooling capacity. Low air pressures will also reduce the cooling capacity.
Mounting:
The Cabinet Cooler mounts to the enclosure through a drilled hole or electrical knockout. The NEMA 12 (IP54) Cabinet Coolers may be mounted on the top or side of the panel. Side Mount Kits are available. (Model 4909 - Small; Model 4910 - Large.) NEMA 4 and 4X (IP66) Cabinet Coolers may be mounted on the top of the panel or on the side of the panel if a Side Mount Kit is used (Model 4906 - Small; Model 4907 - Large).
Solenoid Valve and Thermostat:
Cabinet Cooler Systems with thermostat control include a solenoid valve and thermostat that limit the flow of compressed air to only when cooling is needed. The solenoid valve is rated 120V, 60Hz or 110V, 50Hz. It is UL Listed and CSA Certified.
The thermostat is factory set at 95°F (35°C). It will normally hold ±2°F (1°C) inside the cabinet. It is rated 24VAC-240VAC, 50/60Hz, 24VDC and is UL Recognized and CSA Certified. 
Electronic Temperature Control:
EXAIR’s digital ETC™ (Electronic Temperature Control) provides precise temperature control for your electrical enclosure. It can accurately maintain a constant temperature that is slightly under the maximum rating of the electronics, permitting just enough cooling for the electronics without going so cold as to waste compressed air.
The LED readout of the ETC displays the internal temperature of the electrical enclosure (°F or °C) that is constantly being monitored by a quick response thermocouple. The control activates the solenoid valve (included) when the temperature setting is exceeded. The polycarbonate plastic enclosure of the ETC is suitable for NEMA 12, 4 and 4X environments. (Cabinet Cooler not included.)

High Temperature Cabinet Cooler Systems for ambients of 125° to 200°F (52° to 93°C) are available (shown right). Internal components can withstand high temperatures (like those near furnaces, ovens, etc.) High Temperature Dual Cabinet Cooler Systems are also available.
Non-Hazardous Purge Cabinet Cooler Systems (shown left) are ideal for dirty areas where contaminants might normally pass through small holes or conduits. Under normal conditions, the NHP Cabinet Cooler System provides a slight positive pressure in the enclosure by passing 1 SCFM (28 SLPM) of air through the cooler, when the solenoid valve is in the closed position. When the thermostat detects high temperature, it energizes the solenoid valve to pass full line pressure to the Cabinet Cooler, giving it full cooling capability. The continuous purge of the NHP Cabinet Cooler System keeps dirt, heat and moisture out of the enclosure.
Type 316 Stainless Steel NEMA 4X Cabinet Cooler Systems (shown right) are suitable for food service, pharmaceutical, harsh and corrosive environments, and other applications where 316SS is preferred. Capacities from 650 to 5,600 Btu/hr. (164 to 1,411 Kcal/hr.) are available.

Side Mount Kits
EXAIR's Side Mount Kits make mounting on the side of an electrical enclosure possible when there is limited space on the top or side. (NEMA 4 and 4X Cabinet Cooler Systems must be mounted vertically.) Side Mount Kits maintain the NEMA rating of large and small NEMA Type 12, 4, and 4X enclosures. they mount in a standard electrical knockout (1-1/2 NPS). Side Mount Kits for NEMA 12 Cabinet Cooler Systems have an aluminum construction. Those for NEMA 4 and 4X Cabinet Cooler Systems are Type 303 or Type 316 stainless steel.

Cooling Control Panels in a Glass Plant
The Problem: Few companies contend with more heat related problems than do glass manufacturers. Control panels in close proximity to molten glass are particularly susceptible. High ambient temperatures caused constant "nuisance tripping" of the circuit breakers. The "quick fix" solution — opening the panel doors — allowed dirt to enter the panels and created a potential safety hazard.
The Solution: EXAIR Model 4330 Cabinet Cooler Systems were installed on each control panel. Cold air was directed through the Cold Air Distribution Kit over the circuit breakers. Thermostat control assured that the Cabinet Coolers would activate only when internal temperatures approached critical levels. The panel doors were closed against dirt infiltration and shock hazard. Downtime was eliminated.
Comment: The inherent reliability of the vortex tube operated Cabinet Cooler was the important advantage in this application. Because they have no moving parts, EXAIR Cabinet Coolers are virtually impervious to hostile environments. Glass plants, steel mills, foundries, and casting plants are just a few of the facilities benefiting from this simple, yet effective technology.
Cooling and Purging a Pultrusion Control
The Problem: In the pultrusion process, resin coated fibers are assembled by a forming guide, then drawn through a heated die. Residual heat from the die caused electronic malfunctions at the control station located immediately downstream.
The Solution: In minutes, a Model 4730 NEMA 4 (IP66) Cabinet Cooler System was installed on the control module. Its 2,000 Btu/hr. (504 Kcal/hr.) cooling capacity more than offset the additional heat load produced by the die. Heat related malfunction and downtime were eliminated.
Comment: The ability of EXAIR's Cabinet Cooler to maintain a slight positive pressure within the enclosure was an important additional benefit in this application. This purging feature assured that dust from the surroundings would not infiltrate the enclosure and compromise the sensitive electronic components. The Cabinet Cooler also maintained the NEMA 4 (IP66) integrity of the enclosure which was necessary for the occasional washdown of the die and surrounding surfaces.
