An air blast cooler uses ambient air to cool process fluids (e.g.: lubricants). It is an extended surface heat exchanger and is sometimes known as a fin fan cooler.
Our air blast coolers are part of our range of coolers for industrial use. We produce coolers ranging from small products for ship stabiliser to units measuring more than 6 meters long and weighing several tons for high voltage direct current (HVDC) installations.
Air blast coolers are used for process cooling. Ambient air is forced over a heat exchanger to remove unwanted heat from a closed circuit containing process fluids or intermediate coolant. Coolant return temperatures can be as low as 10°C above ambient air.
The header is the part of the cooler where the coolant passes into the heat exchanger tubes. Depending on the application, the design pressure and your requirements, the header can take various forms, including tubular, rectangular with cover plates, or plugged.
The coolant may pass several times down the length of the cooler in a crossflow or counter-flow arrangement. The positions of the baffles within the headers determine the number of passes. The best arrangement depends on the temperature differentials and overall flow rates of the tube side and ambient streams.
At Sterling Thermal Technology, we work with you to design and manufacture the ideal air blast cooler for your requirements. Together, we discuss the primary considerations for your application and ensure your air blast cooler is suited to the purpose. Get in touch today.
Air blast coolers can work in a closed-circuit arrangement, which is significantly better than an open cooling tower. By avoiding direct contact between air and water, a closed-circuit system creates a cleaner cooling system less prone to fouling and corrosion.
With this reliable system, we can reduce operational costs and avoid downtime.
We design and manufacture air blast coolers with a tube to tubeplate construction by roller expansion or seal welding. As a result, our coolers deliver exceptional levels of reliability and availability.
We choose from a wide range of fin types and tube material, including titanium and duplex steel. We configure it with vertical or horizontal mounting to suit your site limitations. By utilising plate-fin matrices, we can build units in modular form to meet any of your cooling requirements.
We design our plenum chambers to ensure optimum air distribution over the heat transfer surface while minimising air recirculation and leakage.
The speed of rotation of the fan is the main variable that determines the noise level of the equipment. Noise is a major consideration in all designs. Our thorough design ensures the resulting operational noise levels meet contract requirements. In addition, for very low noise level requirements, we can offer cylindrical silencers.
Dependent on the properties of the coolant and the corrosion potential of the atmosphere, we offer a wide range of tube and fin materials.
As an experienced cooler manufacturer, we design and produce air blast coolers for most industry sectors, including chemical, power generation, defence, oil and gas, food and beverage and marine.
