HEAT PANEL PRODUCTION PLANT

Built: 1985 – 1998

Composed of:

Welding Line Description

There are two welding lines available at the site, one line is dedacated to producing single radiators. The other line is dedicated to producing double radiators. The lines are set out in a flow process configuration, beginning with the multispot operation and concluding with the final assembly/testing. Each station is connected with transfer conveyors.

The lines operated until July 2005. The lines were maintained to the highest standard during their working life with a strong emphesis placed upon downtime reduction. The lines operated on a two shift basis.

Product Range

The lines are capable of producing radiators ranging in height from 285 mm to 900 mm. The radiator lengths produced were 500 mm to 3000 mm. The lines arte set to produce two connection pruduct. The doubles line is capabable of producing four connection product in singles or doubles.

Upgrades

The lines have been progressively upgraded troughout their time. The controls on the line have been converted to PLC type.

The lines comprise of the following:

LEAS FOLDING LINE

The folding line has operated at the plant since 1994.The process line comprises of the following. This production process was dedicated to produce folded radiator panels in praparation for the welding process. The line was capable of producing radiators in the following heights: 300 mm, 400 mm, 500 mm, 600 mm and 700 mm heights. The radiator panel produced varied from 500 mm to 3.000mm in length. Each Station along the process is supervised by using PLC controls. The line can be changed over to different heights within minutes, as the heights are pre-programmed. The folding process pre selects the panel lengths as they enter that part of the process then the folder will fold either a long panel or two short panels depending the precribed lengths.

Each part of the process is linked by conveyors, which accommodate the panel tranfer.
