Galvanising Plant & Equipment

Resting on longstanding experience in galvanizing wires, zenith offers complete general galvanizing turnkey plant and related equipment focusing on zinc consumption reduction and optimized logistics.

We at zenith can deliver a custom-made furnace to you, whether it is with a ceramic bath or a steel kettle. It can be used alongside currently-available burner‑systems.
Zenith’s galvanising furnaces are characterised by their high level of efficiency, long service-life, sparing use of resources and low operating and maintenance costs.

Ceramic galvanising furnaces:

Ceramic furnaces are used with zinc bath temperatures of up to 600 °C. The ceramic bath guarantees an almost unlimited service life without interruption to the operation.

Using special-shaped blocks, zenith prevents damage to the bath due to zinc permeating in over time. These blocks are installed in such a way as to form a system of cool-air channels.

Depending on your choice, the heat energy is transferred to the galvanising-bath either by means of a heat hood across the surface of the bath, or by direct contact with the hot zinc by immersion-burners.

A sectional steel construction clad in corrugated iron, which surrounds the brickwork, absorbs the hydrostatic pressure of the liquid zinc and thus protects the ceramic material from crack formation.

Steel kettle galvanising furnaces:

Zenith  manufacturers of galvanising furnaces, deliver equipment with burners developed specifically for galvanising. These burners allow the furnaces to reach an efficiency-level of up to 75 percent

Steel kettle galvanising furnaces operate particularly economically at temperatures of up to 460 °C. Unlike the burners commonly used in the past, the current burners fuelled by natural gas operate in modulating mode. This allows them to ensure the sort of even and gentle heating which was previously available only with electrically-heated furnaces.

Diffuser plates on the burners guide the gas stream along the inner wall of the furnace. This gives rise to a combination of radiant and convection heat which means that the burners transfer high heat output to the kettle at relatively low average temperatures.

The control system continuously adjusts the power to the throughput of the furnace. It also prevents extreme jumps in temperature, which, in turn, prevents unnecessary stresses on the galvanising kettle.

An array of further features contributes to minimising energy requirements: The multi-layered insulation design, up to 300 mm in thickness, reduces heat loss; furthermore, the new ceramic coating of the fibre insulation reflects the thermal radiation into the inside of the furnace
