Kooltronic enclosure air conditioners use closed-loop refrigeration cooling to remove heat from an electrical enclosure while keeping the enclosure's internal air isolated from the surrounding ambient air.

The system cools, dehumidifies, and recirculates air inside the cabinet, helping protect heat-sensitive components from excessive temperature, humidity, dust, and other airborne contaminants.

Start with the enclosure size, internal heat load, maximum ambient temperature, desired internal enclosure temperature, required NEMA rating, available mounting space, and electrical supply.

Kooltronic offers enclosure air conditioners in a wide range of sizes, mounting configurations, and cooling capacities from approximately 1,000 to 30,000 BTU/H.

If the required capacity is not known, Wayne Products can review the application information and help determine an appropriate Kooltronic configuration.

Useful sizing information includes:

• Enclosure height, width, and depth
• Heat generated by the equipment inside the enclosure
• Maximum surrounding ambient temperature
• Desired internal enclosure temperature
• Indoor or outdoor installation
• Required NEMA rating
• Available voltage and frequency
• Available mounting space and preferred mounting location

Photos of the enclosure and existing cooling equipment are also useful, especially when replacing an older unit.

A fan or filtered blower may be sufficient when the surrounding ambient air is cool and clean enough to remove the enclosure heat.

An enclosure air conditioner is appropriate when active refrigeration cooling is required, when the desired enclosure temperature cannot be maintained with ambient air alone, or when a sealed closed-loop system is needed to protect the enclosure from the surrounding environment.

Kooltronic offers several enclosure air-conditioner families for different capacities, enclosure ratings, mounting restrictions, and environments.

• Guardian Series: All-weather air conditioners maintaining NEMA 12, 3R, and 4 ratings, with capacities from approximately 1,000 to 26,000 BTU/H.
• GuardianX Series: NEMA 4X configurations intended for corrosive environments, with capacities from approximately 1,000 to 26,000 BTU/H.
• Guardian / GuardianX 480 V: 480 V configurations for applicable indoor/outdoor applications.
• Access Series: Ultra-slim air conditioners for limited-depth applications, with capacities up to approximately 3,000 BTU/H.
• SlimKool Series: Narrow-width units designed for shallow electrical enclosures, with capacities from approximately 4,000 to 11,000 BTU/H.
• Hazardous Location Series: Specialized units for applicable NEC Class I, Division 1 and 2 installations.
• Micro-Mini Series: Compact indoor units for smaller cooling requirements, with capacity up to approximately 1,000 BTU/H.
• Horizon Series: Top-, bottom-, or internal-mount solutions with capacities from approximately 2,500 to 12,000 BTU/H.
• TrimLine Narrow Mini Series: Narrow indoor configurations with capacities up to approximately 2,500 BTU/H.
• Rack-Mount Series: Air conditioners designed for standard 19 in. equipment racks, with capacities up to approximately 5,000 BTU/H.
• Intrepid Series: High-capacity outdoor units with capacities up to approximately 30,000 BTU/H.
• TrimLine Water-Cooled Series: Water-cooled enclosure air conditioners for applications where clean cooling water is available.

Not every series is appropriate for every application. Confirm enclosure rating, capacity, voltage, mounting, and environmental requirements before selecting a model.

The Guardian and GuardianX families are designed for indoor/outdoor applications without requiring separate weather shielding.

Guardian units can maintain NEMA 12, 3R, and 4 ratings depending on the model. GuardianX units are designed to maintain NEMA 4X and are intended for more corrosive environments.

SlimKool and certain other Kooltronic series are also available in outdoor or washdown-rated configurations. Always match the air conditioner to the required enclosure rating.

Kooltronic offers several configurations for space-restricted installations.

• Access Series: Ultra-slim depth for compact door or panel mounting.
• SlimKool: Narrow-width design for shallow electrical enclosures.
• TrimLine Narrow Mini: Narrow mounting width for smaller indoor applications.
• Horizon Series: Horizontal top-mount and other configurations when side mounting is not practical.

Provide Wayne Products with the available mounting dimensions when requesting a quote.

Yes. Kooltronic offers a Hazardous Location Series designed for applicable NEC Class I, Division 1 and Division 2 installations.

These applications require careful review of the area classification, enclosure, purge system, electrical requirements, and exact model certification. Do not substitute a standard enclosure air conditioner for a hazardous-location unit.

Kooltronic air conditioners are available in configurations that maintain NEMA 12, 3R, 4, or 4X enclosure ratings, depending on the series and model.

The air conditioner must be selected and installed for the required enclosure rating. Do not assume that every model carries the same rating.

Yes, but allowable mounting orientation depends on the series. Kooltronic offers panel-mounted, door-mounted, top-mounted, bottom-mounted, internally mounted, and rack-mounted configurations.

Select a series designed for the required mounting position rather than changing the orientation of a unit that was not designed for that use.

The condenser air inlet and exhaust must have adequate clearance for unrestricted airflow. Air inside the enclosure must also be able to circulate around heat-producing components.

Do not block the exterior intake or exhaust, and do not install internal components where they obstruct the conditioned-air supply or warm-air return.

Yes. Kooltronic offers replacement solutions for many older Kooltronic units and competitor air conditioners.

Adapter plates and plenums may be available to reduce enclosure modifications when replacing an existing unit.

Provide the existing manufacturer's model number, enclosure cutout dimensions, voltage, cooling capacity, and photos when requesting replacement assistance.

Closed-loop cooling keeps the conditioned air inside the enclosure separate from the ambient air outside the enclosure.

Warm enclosure air passes through the evaporator side of the air conditioner, where heat is removed. The cooled air is then returned to the enclosure while the collected heat is rejected to the outside through a separate condenser airflow path.

Many current Kooltronic enclosure air conditioners include a programmable thermostat or thermostatic temperature control, depending on the series and model.

Certain programmable models also support additional monitoring or alarm functions with compatible accessories.

Condensate handling depends on the model. Many Kooltronic air conditioners include a built-in condensate evaporator that eliminates routine draining under normal operating conditions.

In very humid conditions or with an open or poorly sealed enclosure, condensate production may exceed the evaporator's capacity. Models equipped with an overflow drain should have the drain inspected and kept clear.

Many Kooltronic air conditioners use a reusable aluminum filter on the ambient-air side to help keep the condenser and internal cooling components clean.

Replacement filter size and part number depend on the exact air-conditioner model.

Yes. Kooltronic's aluminum filter media are reusable and can be washed when dirty. Filter recoating adhesive is available for applicable filters after cleaning.

Replace a filter if it becomes damaged or is no longer serviceable.

Service frequency depends on the operating environment. Kooltronic recommends regular filter maintenance and generally suggests inspection at least every six months.

In dusty, dirty, or heavily contaminated environments, filter maintenance may be needed every one to three months or more frequently depending on actual conditions.

Keep the ambient-air inlet and exhaust free of dirt and obstructions, inspect and clean the filter as needed, maintain adequate airflow clearance, and inspect condensate drains where applicable.

Also make sure airflow inside the enclosure is not blocked by wiring, components, or other equipment.

Follow the maintenance instructions for the exact Kooltronic model installed.

Start with the model number and electrical information on the unit nameplate.

If the model is difficult to read, send Wayne Products clear photos of the nameplate, complete air conditioner, enclosure mounting, and existing cutout.

That information can help identify the current model, possible replacement, and compatible mounting or adapter options.

Yes. Kooltronic maintains information on legacy and discontinued air-conditioner families, and current replacement options are available for many older units.

Provide Wayne Products with the existing model number, voltage, enclosure rating, cooling capacity, and mounting dimensions whenever possible.

The most useful information includes:

• Existing manufacturer and model number
• Voltage and frequency
• Cooling capacity if known
• Required NEMA rating
• Enclosure dimensions
• Existing enclosure cutout or mounting dimensions
• Indoor or outdoor location
• Photos of the existing unit and installation
