Advantages of BMCG Is marketed in Kgs and could be measured easily. Less Carbon formation – hence low maintenance and long life of nozzles. Operator friendly. Reduces fuel inventory. Yields 40 % cost savings on overall

cutting cost.

Advantages of using BMCGAdvantages of using BMCG

Virtually impossible to back fire or flash backVirtually impossible to back fire or flash back Flame is much less Luminous, so less harmful to Flame is much less Luminous, so less harmful to eye-sighteye-sight

Less cylinder handling costLess cylinder handling cost

Lower frequency for changing the cylindersLower frequency for changing the cylinders

Safer as the operating pressure is lower in cylinder Safer as the operating pressure is lower in cylinder

Advantages of using BMCGAdvantages of using BMCG

Faster cutting rate as secondary flame is higherFaster cutting rate as secondary flame is higher (19080 Vs 8570 DA Kcal).(19080 Vs 8570 DA Kcal).

For BMCG the same torch used for DA can be used.Only the cutting nozzle has to be changed.

3 seater torch / nozzles give better economy and lesser flash back

Easy Change over from DA to BMCG
