High Static Vertical Fan Coil - High Static- Common Applications

Polar by Siwa’s VAHU air handling unit is specifically designed to satisfy extreme capacities at external static pressures below 1.75″. They can be ducted covering a huge area with the motor capable of withstanding the extremities of static pressure caused by ducting. This is guaranteed to provide a comfortable environment for both commercial and residential applications. These are great when no zonal control is required or zonal control is controlled using VAV boxes and a large space is needed to be heated or cooled. Examples are a gym, airports, warehouses etc. 

Some advantages of VAHU vertical air handling fan coils include:

  • 300 psi operating pressure. Tested to 500 psi.
  • Customization ability
  • Control versatility (BMS or standalone)
  • High CFM
  • Easy to install and duct
  • Suitable for low water temperatures during heating

Some of the add on options include:

  • Standalone control systems with thermostats
  • Valves
  • MERV 8 filters
  • Stainless steel drain pans
  • Sound insulation
  • Thermostats
To summarize, high static ducted vertical air handling fan coils are a popular option for commercial and industrial buildings. Firstly, they are designed to handle high static pressures, allowing them to distribute air more effectively over longer distances. Secondly, they are ideal for buildings with limited floor space, as they can be installed in tight spaces. Thirdly, they offer customizable settings, allowing for precise temperature and airflow control. Moreover, they are energy-efficient, resulting in lower operating costs. Additionally, they operate quietly, providing a comfortable environment without the added noise. Finally, they are easy to maintain and service, ensuring optimal performance and longevity.
