Low Loss Header Calculator
The FlexEJ low loss header calculator will allow you to size a low loss header based on the flow or power in your primary and/or secondary circuits. If you have any questions or require guidance on using this calculator please contact us.
The FlexEJ LLH Calculator
Please rotate your screen. Our LLH calculator requires just a little more horizontal space than we can squeeze into your current rotation.
Low Loss Headers can either have multiple connections to the body - 1 pair per circuit - or these can be combined before/after the LLH in horizontal headers (our preference) which results in just one pair of primary connections and one pair of secondary connections.
The calculator covers both connection schemes by providing 4 separate primary and secondary inputs plus a total which represents the horizontal header implementation.
Fixed standard values for the properties of water are assumed when converting from power to flow rate.
Standard Products and Enquiry Form
As you use the calculator, you will see below any available FlexEJ standard low loss headers that match your application and an enquiry contact form.
FlexEJ standard low loss headers are designed for use with horizontal headers.
We offer short lead times on manufacture of bespoke low loss headers for use without horizontal headers - individual circuit connections to the body - and larger sizes above the standard range.
