Our Product Portfolio

Every radiator we manufacture undergoes rigorous pressure testing and specialized anti-corrosion treatments to ensure a lifetime of leak-proof performance.

Why transformer manufacturers choose Prima Transfab

Built on 40 years of engineering heritage — now dedicated exclusively to radiator fin manufacturing.

Automated Production Line

A fully automatic 65-metre production line ensures every fin is formed, welded, and tested with zero manual variation. Consistent quality across every batch, every order.

100% Pressure Tested

Every single assembly undergoes hydraulic leak testing before dispatch — not sampling, every unit. Zero leakage guarantee on all radiators supplied.

Precision Dimensional Accuracy

Servo-controlled cutting holds every fin to ±1 mm of your specified length. Consistent dimensions mean faster assembly at your factory and zero rework on fit-up.
