K2 Technology
Electric drive, bidirectional rotation, and safety systems built specifically for hot-dip galvanizing small parts — nuts, bolts, washers, and nails.
Electric, not pneumatic
K2's motor draws power directly from your existing crane or hoist wiring — no separate compressed-air line to run to an existing kettle. Pneumatic centrifuges need that extra air infrastructure; K2 doesn't.
Rotation that actually moves the load
K2 spins in both directions, so the parts inside the basket or fixture actually move within the zinc instead of staying pressed together in one static mass. Zinc reaches every surface with no shadowing between parts, and dross is brought up to the surface instead of trapped inside the load.
It also solves a problem every batch galvanizer knows: when a loaded basket goes into the bath, the goods clump together and the zinc around them freezes solid for a moment. If that clump doesn't thaw fast, the flux underneath burns before zinc reaches it — ruining the coating. K2's rotation breaks the clump apart and drives heat and zinc through the load immediately, so it thaws fast enough to protect the flux.
Built for washers — the hardest item to galvanize well
Thin, flat, with a center hole, washers are the classic case for zinc bridging over the hole and uneven drainage when parts nest together. Constant, controlled movement is the only real fix — which is exactly what K2's rotation gives every load.
Safety at every step
Controlled acceleration
A VFD (frequency converter) ramps the motor up and down instead of snapping to speed. A strong air motor can accelerate abruptly enough to twist and tangle the chains the centrifuge hangs from — the ramped electric drive can't do that.
Two-step remote control
Jog the load forward or back for slow movement while it's submerged, without slamming it around. Spin only engages after a two-button interlock — pressed together — so full-speed rotation can never start by accident.
Basket or fixture — matched to the job
K2 takes either a basket or a fixture, depending on what you're loading.
| Basket | Fixture | |
|---|---|---|
| Best for | Small parts | Rods and bars |
| Max length | 500 mm | 1500 mm |
| Max load | 100 kg (quality limit) | 150 kg goods (+100 kg fixture weight) |
K2's structural capacity is 250 kg. A basket could physically carry that much, but more than about 100 kg of goods means the load can't thaw evenly — the flux-burn risk above gets worse as the pile gets denser. A fixture holds parts individually rather than piled together, so it avoids that problem and can carry more: 150 kg of goods plus its own 100 kg brings the total right up to the machine's 250 kg limit.
Bath temperature: low vs. high
Zinc baths run at one of two temperatures: a conventional 450°C, or a high-temperature process around 550°C — standard practice for centrifuge galvanizing of small parts under EN ISO 1461. Higher temperature works faster, but it also attacks steel equipment faster: baskets and fixtures dissolve into the bath more quickly, and every kilogram of dissolved iron produces roughly 25 kg of hard zinc (dross) that has to be removed from the kettle. Worth factoring into equipment lifetime, whichever bath you're running K2 in.
