Efficient outdoor cooling for external spaces or semi-open areas
Evaporative cooling is the ideal solution when conventional air conditioning isn't possible, especially in open spaces without walls to contain the air.
Outdoor cooling
Seeley International provides energy-efficient, eco-friendly evaporative cooling solutions, specially designed for semi-open and outdoor spaces such as places of worship and temporary installations. Unlike traditional air conditioning, evaporative cooling works by drawing in fresh air and cooling it through evaporation, making it ideal for spaces with limited enclosure or airflow. This natural cooling method ensures precise climate control while minimizing energy usage and environmental impact.
Evaporative cooling is the perfect solution for open or semi-open environments where conventional systems struggle. It maintains a comfortable, stable atmosphere, reduces energy costs, and promotes sustainability.
By choosing our cooling solutions, you create an environment that enhances attendee focus and engagement. Our systems not only improve comfort but also offer long-term savings, lower energy consumption, and support your sustainability goals.

Outdoor cooling units Benefits
Effective Cooling in Semi-Open Spaces: Evaporative cooling works well in semi-open areas by efficiently cooling the air through water evaporation while allowing air to flow freely, maintaining comfort without requiring a fully enclosed space.
Energy Efficiency: It consumes less energy compared to traditional air conditioning, making it a cost-effective cooling solution for semi-open spaces, where ventilation is key.
Eco-Friendly: Evaporative cooling uses water and natural airflow, reducing environmental impact in areas with less confinement.
Cost-Effective: With lower operational and maintenance costs, it offers an affordable and sustainable cooling solution for areas with partial exposure to the outside.
Comfortable and Stable Environment: These systems maintain consistent temperature and humidity levels, ensuring a comfortable atmosphere for people in outdoor or semi-open spaces, enhancing focus and engagement.
Seeley International’s premium evaporative cooling solutions are the perfect choice for outdoor spaces, places of worship, and temporary installations, providing efficient and eco-friendly air conditioning.

Ideal for industries, factories, warehouses, and large semi-open and open spaces, Seeley International’s evaporative air conditioning unit offers a cost-effective cooling solution. It delivers efficient cooling while consuming up to 80% less energy compared to refrigerated systems. This makes it especially effective in industrial and high-traffic areas where doors are often opened and closed.
Evaporative cooling is well-suited for various sectors, including farm cooling, textiles, plastics, pharmaceuticals, and commercial spaces, as it provides numerous benefits for Indoor Air Quality (IAQ). These include continuous fresh air circulation, natural air filtration through cooling pads, and the reduction of pollutants, dust, and odors. By adding moisture to the air, it helps control humidity, preventing dryness, dust, and static electricity. Unlike traditional HVAC systems, evaporative cooling doesn’t recirculate air, preventing the buildup of harmful gases. This results in a healthier work environment, enhancing comfort, reducing respiratory irritation, and increasing productivity.

Industrial air conditioning unit Frequently Asked Questions
- Evaporative air conditioners (coolers) are excellent for health
- They supply 100% fresh, filtered air into your building that is not recirculated, improving Indoor Air Quality (IAQ) of the space, supporting customer and staff well-being
- They remove unhealthy pollution from your indoor environment
- They provide basic moisture that the human body needs
- They remove static electricity; they can assist in reducing the effects of illnesses such as asthma.
A high inlet water temperature does not have a marked effect on the supply temperature of Seeley International’s evaporative air conditioners.
Yes. Outdoor areas have no walls to contain the cool air. These spaces would be impossible to cool using refrigerated air conditioning because this relies on recirculating and reusing air from a sealed area. Evaporative air conditioners (coolers) can easily supply a flow of fresh and cool air to open and semi open areas since the air is exhausted naturally.
In most cases evaporative air conditioners (coolers) marginally increase humidity, keeping in mind that temperature has also dropped significantly. It is the combination of temperature, humidity and airflow that creates human comfort and evaporative air conditioners are used widely around the world because they can create comfortable conditions. For example, 80% humidity and 30°C (86°F) is very uncomfortable, but 80% humidity and 16°C (61°F) is very comfortable. Comfort is also improved by increasing air velocity in hot conditions and evaporative air conditioners create sufficient air movement to minimise the effects of humidity.
Air inside the building collects heat, moisture and impurities and must be exhausted. The evaporative air conditioner (cooler) provides 100% outside air which must be relieved from the building. If the building is sealed, the effectiveness of the cooler(s) will be reduced. Mechanical extraction or even just leaving some doors or windows open helps remove unhealthy air from the indoor environment by supplying 100% fresh, filtered air. For this reason, evaporative air conditioners (coolers) are much healthier than refrigerated air conditioning.
