QINGDAO, CHINA — COLTEX has recently completed the preparation and shipment of a CTACD1526W cabinet air conditioner sample for an LV switchgear project in the Middle East.

The unit will be installed and evaluated under actual operating conditions before the customer proceeds with the next stage of the project.

The shipment follows earlier technical discussions regarding the electrical cabinet configuration, operating environment, installation arrangement and cooling requirements.

Instead of proceeding directly with a larger quantity, the customer selected a sample unit for initial installation and testing. This approach allows the cooling solution to be evaluated under real operating conditions and provides practical feedback before further project deployment.

Evaluation Under High-Temperature Operating Conditions

Electrical equipment operating in the Middle East can be exposed to demanding environmental conditions, particularly high ambient temperatures.

Inside an LV switchgear cabinet, breakers, busbars, contactors and other electrical components continuously generate heat during operation. If this heat is not removed effectively, the internal temperature of the enclosure can increase significantly.

For this reason, cabinet cooling selection should take into account more than nominal cooling capacity.

Cabinet dimensions, internal heat generation, component arrangement, airflow paths, mounting position and external ventilation conditions can all influence actual cooling performance.

The sample unit will allow these factors to be evaluated during installation and operation.

The customer can check the cabinet temperature, airflow distribution, mounting arrangement and maintenance accessibility under real site conditions. This information can then be used to determine whether any adjustments are required before the project moves forward.

Sample Testing Before Further Deployment

Sample testing is an important step for projects where cabinet air conditioners are expected to operate continuously or under high-temperature conditions.

Even when the rated cooling capacity is suitable, installation conditions can affect actual performance.

For example, restricted airflow inside the cabinet may create local hot spots around high-heat components. On the external side, insufficient clearance around the condenser section may reduce heat dissipation.

These practical conditions are often easier to identify through an actual installation than through technical drawings alone.

After the sample has been installed and tested, the operating feedback will provide a basis for confirming the final cooling arrangement and any subsequent project requirements.

Supporting Electrical Cabinet Cooling Projects

The Middle East shipment represents another application of COLTEX cabinet cooling equipment in the power distribution sector.

Cabinet air conditioners are commonly used in LV switchgear, electrical enclosures, control panels, power distribution cabinets, outdoor power systems, telecom equipment and energy storage applications where stable internal temperature control is required.

Different projects can have very different thermal management requirements.

For this reason, COLTEX normally evaluates the cabinet structure, estimated heat load, ambient temperature, airflow arrangement and installation conditions before recommending an enclosure cooling solution.

For this project, the current sample shipment provides an opportunity to verify the cooling performance directly under actual operating conditions.

Following installation and testing, COLTEX will continue working with the customer on the technical evaluation and the next stage of the project.

The sample has been shipped by air and is expected to arrive within approximately 2–3 days, allowing the customer to begin installation and testing without a long logistics delay.
