Copper tubes, refrigeration fittings and bending to drawing

How to choose

The tube is chosen for the refrigerant and the pressure, and bending is ordered with a drawing

Copper tube for refrigeration differs from plumbing tube in its internal cleanliness and the way it is packed – the coils are capped so that no moisture or contamination gets inside. An open coil that has been lying around the shop floor can introduce water into the circuit, and water combined with oil forms acids that destroy the compressor.

Refrigeration fittings means service valves, filter driers, accumulators and liquid receivers. They are chosen for the refrigerant and for the maximum working pressure – with new-generation refrigerants the pressures are often clearly higher than in installations from years ago.

Bending tubes to a drawing is a service, not a shelf product. Instead of assembling the pipework from elbows and brazed joints, you get a finished length with repeatable geometry – fewer joints means fewer places where a leak can appear. In series production it also saves assembly time.
