About 52 L/h at 75% load (~R1,222/h at R23.50/L).
Around 240 kW — full shopping centre essential services or large industrial plants.
Three-phase industrial standard.
Civil design, acoustic/exhaust engineering, bulk fuel, medium-complexity switchgear and CoC commissioning.
If growth, large fire pumps or simultaneous chiller starts push peaks near 240 kW continuous, yes — headroom is cheaper than a mid-life swap.
