How to select HVAC system equipment

1 What goes where?2 Low Loss Headers3 Air & Dirt Separators4 Dosing Pots5 Need something a bit different?6 Let us help

All these products are designed to protect and optimise your heating or cooling system. These products are normally positioned as follows:
Air or Air & Dirt Separator ~ boiler flow lines.
Dirt Separator ~ boiler return lines.
Dosing pots ~ main flow and return.
Low Loss Headers ~ between the boilers and system.

A low loss header decouples the boiler from the system. This allows the boilers/boiler circuit flow to optimise at best efficiency for any system conditions. FlexEJ low loss headers come with sensor ports on all four branches so whatever control system is being implemented you will have the port you need.

These separators keep the system clean with both dedicated and combined units. Air causes corrosion and in extreme cases pump cavitation or air locks. Dirt will reduce boiler efficiency over time and will reduce flow areas in all equipment. Removing both air and dirt will keep the system running efficiently and avoid costly maintenance.

Dosing pots are used to safely introduce inhibitors and other chemicals into the flowing system. Maintaining the correct water chemistry ensures all materials in the boilers, chillers and system are protected from corrosion.

FlexEJ can design and build large, multi-circuit low loss headers to order. We can also offer low loss headers with air and dirt sections and all products in larger diameters for bigger systems. Please let us know what you need.
