Category List

Axial Fan Series

Axial flow fans are a type of industrial fan designed to cool equipment and machinery that heats up after use. These compressors produce airflow parallel to the axis, enabling them to use impellers to draw in air and discharge it in the direction of the axis.
Our axial fan thermal management solutions come in a wide size range, starting at 15 mm and going up to 910 mm. These fans are built with sleeve or ball bearings and can last up to 50,000 hours. Installing them to process cooling in machinery or systems, deliver spot cooling, and improve Indoor Air Quality (IAQ) in warehouses, data centers, factories, and foundries are just some of the uses for the axial fan.
Integrating an axial fan as part of your heat management solution has a range of benefits, providing you with the following:
  • Efficient airflow
  • Variable speeds
  • Durable construction
  • Quick maintenance
  • Improved lifespan

Centrifugal Blowers

A centrifugal blower is a type of pump or motor that moves air using centrifugal forces generated by the rotations of an impeller. The impeller pulls air or fluid into the blower and pushes it out via an outlet. With the impeller being the critical element, it consists of a series of blades built around a central hub, which is then connected to a fan.

Drive designs range from belts to direct drive, which influences the rotation speed of the impeller. The speed and efficiency of these blowers make them highly adaptable to various applications. For example, centrifugal blowers are commonly found within residential and commercial HVAC systems.
Some of the advantages of integrating these blowers into your thermal management program include the following:
  • First-rate energy efficiency
  • Enhanced durability
  • Overloading restrictions
  • High versatility
  • Simple maintenance

Build Your Thermal Management Program Today

Building a thermal management program that succeeds requires a firm understanding of the concepts of heat transfer. Delta products utilize all three of the primary methods of heat transfer within its products and when building integrated systems for businesses worldwide.

When deciding which solutions best suit your business, consider the following three heat transfer methods.



Conduction naturally transfers thermal energy through objects coming into contact with each other. Heat may be transferred by components touching each other or by electronic devices contacting external surfaces.

Cooler objects will always draw energy away from hotter objects. This is the least effective energy transfer method because it relies on large surface areas.



Radiation may be used for applications like vacuums. Energy is emitted via electromagnetic waves. The movements and interactions of charged particles create electric and magnetic fields to convert kinetic heat energy into electromagnetic energy.

This niche heat transfer method may not necessarily impact your business, but understanding its role within the industry can provide you with invaluable insight.



Convection consists of the movement of air to redistribute thermal energy. Cooler air will pass by warmer devices to draw air away from the device. It may happen naturally through natural air currents or manufactured via air conditioning systems or EC fans.

Within any thermal management system, convection heating solutions will always form the last step in the process.
