• Water and specifie gasdistribution is integrated in each unit

• Ali distribution lines are placedalong the fumace-line

• Each unit has its own electronic control system

Water, Gas• Central water and

gas supply

• Less space required• No special construction and foundation work needed• Centralized supply of energy and fluids• Extremely short assembling time• Ideal conditions for integration into production lines

Electric and electronic connections• Each unit is already equipped with ail needed connections

Installation and assembling/f ~q

/'

Genuinemodular systemEach unit is equipped with:• Its own electric supply cabinet• Its own flow-meter cabinet• Its own power supply and electric control• Its own specifie control

Maintenance work on a unit can be executedwithout interrupting the production

Transfer ofloads on one level• Only movements in two directions

on one plan• Improved safety for user, since the

handling of loads is carried out behind the fumace-line• Extremely simplified handling

Quenching tanks• Mobile quenching tanks• Each tank can reach under each fumace• The tanks are automatically closed by air-tight covers• The oxidation during quenching is avoided by means of

inert protective gas

Exhaust tubes• Are already included

• The vapors areevacuated at theirpoint of origin and directed intoa central evacuation pipe

~~~~!~Y&rapid carburizing process

ECOCARBis a new gas-carburizing process patentedby Sala, which stunningly reduces the gas-carburizingtime whilst improving the metallurgic quality of the parts.

Example:Gas-carburizing of gear box pinion made of 27 Cr M04 ~effective depth at 650 HV = 0,33 mm /550 HV = 0,37 mm '

Quenchingin water, emulsion, synthetic liquids, oil (up to 200°C),salt (180-550°C) and gas N2 (up to 5 bars)
