FREE TOOL · PRMS SIZING

Which PRMS Capacity Do You Need?

Add the equipment this station will feed and we'll recommend a capacity. This is a sizing estimate, not a final engineering spec, but it's a solid starting point before you talk to us.

Sizing calculator

Enter each piece of equipment's peak gas demand. If you only know its heat input in kW, switch the unit and we'll convert it for you.

Safety headroom: % (15–20% is typical, to cover peak demand spikes)

About this tool

How accurate is this calculator?

It gives a reliable starting estimate based on your equipment's peak gas demand plus headroom. Final sizing should always be confirmed with us against your actual equipment specifications before you order.

How do you convert kW to Nm³/h?

We use a typical natural gas calorific value of about 10.5 kWh per Nm³. This is an approximation, actual gas composition can shift the figure by roughly 10%, which is one reason we confirm final sizing directly.
