Welcome to Promax Industrial

Industrial liquid storage has to be above average. It has to be stronger, safer and, in most cases, bigger.

Our heavy duty storage solutions meet all of those requirements. They’re manufactured with increased wall thickness and strength to handle specific project applications, and provide you with the safest and most efficient industrial liquid storage in New Zealand.

For over 20 years, Promax has supplied liquid storage tanks for industrial purposes, ranging from stormwater and wastewater to chemical storage and firefighting tanks. They range in size from 200 litres to 30,000 litres and coupled with engineered drawings & QA processes on every tank, the options are virtually endless.  Our Industrial team continues to develop new solutions and further improve our existing range, to keep pace with a dynamic market. It’s little wonder we are known as New Zealand’s industrial liquid storage experts.
