  • The cooler mounts vertically on top of the cabinet through a standard knockout hole. A locking ring provided with the cooler locks it into place.
  • A compressed air line hooks up to the cooler by threading a ¼ NPT fitting to the air inlet.
  • As compressed air enters the cooler, the integrated vortex tube separates the air into hot and cold air streams.
  • The hot stream from the vortex tube is exhausted into the atmosphere by passing through a muffler which ensures low noise levels.
  • The cold air enters the electrical cabinet though an outlet tube located at the bottom of the cooler.
  • As the cold stream enters the electrical cabinet, the hot air within the cabinet starts to rise and is gradually purged through the cooler.

We also offer an optional cold air distribution kit which connects to the cooler’s outlet tube and allows the user to direct the cold stream to specific hot spots within the cabinet. All Supreme Air Products electrical panel coolers are made from stainless steel, which ensures durability.

Here are the key benefits of using a Supreme Air Products™ Cabinet Cooler over traditional fans:

1. Superior Cooling Efficiency

Consistent Temperatures: Unlike fans, which merely circulate air, our cabinet coolers actively reduce the temperature inside control panels, ensuring components operate within optimal temperature ranges. This can prevent overheating, which is critical for equipment longevity and operational efficiency. Wide range of cooling capacities from 550 BTU to 5600 BTU

2. Protection from Environmental Contaminants

Cabinet coolers come with filtration systems, reducing the ingress of dust, moisture, and other contaminants that fans can inadvertently pull into the enclosure. This feature is especially beneficial in industrial settings where air quality might be compromised.

3. Energy Efficiency

While fans require continuous power to operate, cabinet coolers use compressed air that are more energy-efficient over time, especially when considering the energy costs associated with cooling large spaces or multiple enclosures.

4. Noise Reduction

Traditional fans can be quite noisy, particularly if multiple units are used in close proximity. Cabinet coolers operate at a lower noise level, contributing to a quieter work environment.

5. Extended Equipment Lifespan

Our cabinet coolers have no moving parts compared to fans, reducing the risk of mechanical failure and the need for maintenance. This leads to higher reliability in critical applications where equipment downtime is costly.

By choosing Supreme Air Products™ Cabinet Cooler, you’re not just cooling your equipment, you’re investing in the performance, safety, and longevity of your operations.

Supreme Cooling, Certified Safety: The OSHA and CE Standard

At Supreme Air Products™, we don’t just cool your electronics—we protect your team. Our Cabinet Coolers are fully OSHA and CE compliant, meeting the strictest global standards for noise control and operational safety. Get world-class cooling performance with the peace of mind that comes from total regulatory compliance.

Cabinet Cooler Specifications

Mounting:

Supreme Air Products™ Cabinet Cooler must be vertically mounted on a flat surface for all enclosure types. An electrical cabinet cooler unit is easy to install through a 1-1/8″ diameter drilled hole or an electrical knockout and is held in place by a locking ring. We offer additional side mount kits for instances where coolers cannot be mounted on the top of the cabinet due to height restrictions.

Humidity:

It is important to close off any openings and vents that may bring in ambient air, especially in warm, hot, or highly humid environments. The relative humidity inside the enclosure stabilizes at 45% for all continuously operating Cabinet Coolers.

Cold Air Ducting:

Our cold air ducting accessory kit routes cold, refrigerated air directly to the heat-sensitive electronics and hot spots inside your electrical enclosure. Rather than letting cold air dump into the bottom of the cabinet, our flexible, non-conductive tubing forces the cold air directly onto critical “hot spots” like VFDs, PLCs, and motor drives. Included with standard adhesive routing clips, this kit can be easily cut to size and custom-tailored to any control panel layout, ensuring uniform temperature control and preventing costly component failures. 

Filtration:

Clean filtered air should be used on all lines that power the Cabinet Cooler. We recommend a 5 micron auto drain filter. Proper filtration is imperative to prevent any accidental water flow into the enclosure. If oil is present in the compressed air supply, use an oil filter with a minimum 0.3 micron rating.

Environmental Considerations

NEMA 4/4X (IP66) – Designed for Electrical Control Panels – Splash resistant, oil-tight, and dust-proof for use in wash down environments as well as outdoor use. Coolers are constructed of Stainless Steel (Type 316) for longevity in wet environments.

NEMA 12 (IP54) – Cabinet Coolers (oil-tight, dust-proof) are used in industrial environments where no liquids can come into contact with the unit. Coolers are constructed of Stainless Steel (Type 304) to withstand harsh corrosive environments.

Cabinet Cooler FAQs

Below is a list of Frequently Asked Questions relating to our Cabinet Coolers. If you need additional help with your application and/or can’t find an answer to your question, please call us at 647-876-6358 or email an Application Engineer at sales@supremeairproducts.com.

Yes, however, there are clear advantages to using the Supreme Air Products™ Cabinet Cooler for this application.

  • Cabinet Coolers have a purge or pressure release valve to allow warm air from the electrical enclosure to escape the cabinet.
  • Cabinet Coolers are designed to achieve ideal cooling capacity in closed spaces, as they have pre-determined temperature settings. Vortex Tubes are better suited for spot cooling in open spaces, as they allow the user to manually adjust temperatures. Since Vortex Tubes are adjustable, they can often over cool electrical components, which can result in damage.
  • Unlike Vortex Tubes, Cabinet Coolers incorporate mufflers to reduce noise levels significantly.
  • Cabinet Coolers have NEMA 4/4X and NEMA 12 ratings, whereas Vortex Tubes do notThe performance is negatively impacted with back-pressure on the cold end exhaust. A Back-pressure of 5 PSIG will change performance by approximately 5°F. A low pressure up to 2 PSIG will not affect performance.
A 0.002 microfarad capacitor can be wired across the leads on the thermostat to prevent it from chattering. This chattering can sometimes occur due to a very slow temperature change. The capacitor simply desensitizes the thermostat to stop the chattering effect. The capacitor is available FREE OF CHARGE at special request.
Supreme Air Products™ manufactures Cabinet Coolers with cooling capacities between 550-2,800 BTU/Hr. from a single unit. If you require additional cooling, we also offer dual cooler units ranging from 3,200-5,600 BTU/Hr.
It’s very simple! Complete our Cabinet Cooler Sizing Form found under the “Specifications” tab and email it to us at support@supremeairproducts.com. A Supreme Air Products™ Application Engineer will reply to you within 24 hours with a recommendation. If you wish to determine the size requirements yourself, visit our “Information Center” tab where you will find all of the necessary instructions.
No. The Supreme Air Products™ Cabinet Cooler will purge warm/moist air from inside the enclosure. The cool air that is being injected into the cabinet will then start to pick up heat, which in turn causes the humidity to drop. A continuously operating Cabinet Cooler will keep the relative humidity at approximately 45%. It is imperative that all openings in your control panel are closed off, as humidity from the ambient air could cause condensation within the panel.
The Supreme Air Products™ Cabinet Cooler must be installed at the top of the cabinet through a standard knockout hole and secured with a locking ring. If there is no room to mount the cooler at the top, we offer additional side mounts that allow for coolers to be mounted vertically on the side of the cabinet. A thermostat at the top of the cabinet is best (but not required), as this is the hottest spot due to the rising hot air. Our Cartridge Thermostat is mounted through a standard knockout hole and held in place by a locking ring.
Our Cabinet Coolers are constructed of either Stainless Steel (Type 304) or Stainless Steel (Type 316) depending on NEMA rating. We do not offer inferior aluminum or plastic coolers that can damage your cabinet. Our coolers are corrosion proof and durable.
The pressure within the cabinet can build up to approximately 2 PSIG, depending on how tightly sealed the cabinet is.
All of our Cabinet Coolers incorporate their own air purge in the mounting base. The cold air enters the cabinet through the center brass tube, while the hot air within the cabinet is exhausted through the perimeter vent on the base of the cooler.
Each application will have a different heat load which will determine the air consumption of your cooler. Generally, you can expect consumption ranging from 8 to 80 SCFM @ 100 PSIG. This will provide cooling capacity of 550-5,600 BTU/Hr. If air consumption is a concern, a thermostat control kit should be incorporated to reduce air usage, as it will ensure that the cooler only operates at a pre-determined temperature.
Our coolers are intended for factory and industrial applications. Noise levels are dependent on the size of the Cabinet Cooler. We offer optional Cabinet Cooler mufflers for applications where noise is a concern. Please refer to our “Specifications” tab for a chart outlining sound levels for each model.
