A practical HVAC filtration guide explaining where pre-filters, fine filters and HEPA filters belong, how each stage protects the system, and why correct filter selection improves air quality, equipment life and maintenance performance.

Selecting the right AHU cooling coil requires more than checking cooling capacity. This guide explains how coil rows, fin density and face velocity affect heat transfer, dehumidification, pressure drop, energy use and condensate carryover. It also includes key equations, a worked example and a practical selection procedure.

Learn how to manage thermal movement in chilled-water piping using anchors, guides, expansion loops, bellows and flexible connectors. This practical guide explains key equations, worked calculations, support arrangements, equipment protection, installation practices and common design mistakes.

Air and dirt separators help chilled-water systems operate more efficiently by removing trapped air, microbubbles, sediment, and magnetite. They improve heat transfer, stabilize water flow, protect pumps and control valves, reduce corrosion, lower pressure losses, and support reliable long-term HVAC performance.

Learn how chilled water pump head is calculated in HVAC systems, including pipe friction, equipment pressure drops, and control valve losses. This guide explains the key steps engineers use to determine total dynamic head for proper pump selection. For detailed calculations and professional HVAC engineering support, contact Nexora.
