Liquid Resistance Starter

PulseTech is a leading Australian supplier of Liquid Resistance Starters (LRS) to mining, metal-recycling, cement, energy, sugar cane and water industry sectors. Our liquid resistance starters are made in Germany using the highest quality materials and components. The robust design of our liquid starters combined with quality manufacturing, results in the highest reliability in the market with minimum site maintenance.

PulseTech provides comprehensive installation, commissioning and maintenance support Australia wide for the liquid starters. We are specialists in the replacement of existing secondary resistance starters and can help you extend the life of your plant. We can specially design and manufacture starters to be interchangeable with your existing starter characteristics and interfaces so that you can easily carry out the replacement during the normal maintenance shutdown of your plant. 

​

We can also supply parts and electrolyte salt for your existing resistance starter. Please send us an enquiry with details of your existing equipment, our product specialists will promptly assist you with your request.

Applications
