The Growing Popularity of Duct Coolers and the Changing Climate Scenario
Temperatures in Pakistan have been rising steadily, driving up the demand for cost-effective and efficient cooling solutions in homes, commercial centers, and industrial units. Among the options available, duct coolers have gained considerable attention over the past few years. These systems cool air through water evaporation and then distribute it via ducts to different areas, making them a relatively economical and practical choice for large spaces.
According to experts, the primary advantage of duct coolers is their low electricity consumption. Compared to traditional electric cooling systems, they use significantly less energy while ensuring a continuous supply of fresh air. This is a key reason for their growing popularity in factories, workshops, wedding halls, warehouses, and commercial centers—they can keep expansive areas cool at a relatively low cost. In a country like Pakistan, where electricity prices are continuously rising, this factor holds particular appeal for consumers.
In hot and dry climates, duct coolers perform at their best. In many parts of Punjab, Khyber Pakhtunkhwa, and Balochistan, where temperatures often exceed 40°C and humidity levels are low, duct coolers can substantially reduce air temperature. The air they produce feels comparatively cooler, fresher, and more pleasant. This is why many industrial establishments consider them a means of providing a better working environment for their employees.
The situation changes during winter. Since the primary function of a duct cooler is cooling, its use is generally halted in colder months, or it is limited to air circulation only. In regions with harsh winters, duct coolers remain effective for only a few months of the year.
However, the rainy season and monsoon present a significant challenge for duct coolers. During this time, ambient humidity is already high, reducing the system’s ability to generate additional cooling through evaporation. As a result, while air continues to circulate, the desired cooling effect is not felt. In some cases, high humidity can even make the environment feel stuffy. If maintenance is inadequate, cooling pads and water systems become prone to bacterial or fungal growth, potentially affecting both health and performance. For this reason, experts emphasize regular cleaning and proper ventilation during the monsoon season.
In Pakistan, Gujranwala has emerged as a major hub for the manufacturing of duct coolers and air-cooling equipment. The city is nationally renowned for its domestic and industrial appliance manufacturing industry. Numerous companies and industrial units are active in this sector, including Super Asia, Bright Corporation, Maxima Air, Pepco Pakistan, Shafiq Industries, Atlas Corporation, Asad Industries, Naseer Brothers, and various other local manufacturers. These enterprises produce industrial coolers, duct coolers, exhaust fans, and related products in a range of capacities to meet diverse needs.
Interestingly, Gujranwala’s industrial identity is no longer limited to fans and household appliances; advanced duct cooling and air distribution systems are also rapidly gaining ground there. In response to rising energy costs, industrial demands, and environmental concerns, local manufacturers are introducing solutions that consume less electricity and are more eco-friendly. While duct coolers do not perform uniformly across all seasons and their effectiveness may be limited during the monsoon, they remain widely regarded in a hot country like Pakistan as an effective, economical, and reliable cooling system. This is why Gujranwala’s industry is not only fulfilling domestic needs but also holds the potential to introduce even more advanced and improved products in the future.
