An established company you can trust

You need to deal with a company you can trust. Entec is not some small, tin-pot set up. The company was founded in 1982 and now has a staff of 80 people.

Entec is a class-leading supplier of instrumentation & electrical solutions, power generation and compression equipment, technical advice and service back-up for New Zealand’s industrial sector.

Our gas detection history

We have a long history in gas detection. John Langslow, our gas detection manager, has been working with Industrial Scientific equipment for over 20 years.

We also work with leading manufacturers such as Ion Science (PID technologies for VOC detection), Teledyne (Oldham and Detcon brands), Uniphos Envirotronic and International Gas Detectors for fixed gas detection systems.

We genuinely care about your safety, and our expertise is second to none – we know what we’re talking about!

As well as being highly knowledgeable, our people are trustworthy and reliable. An ethical approach is vital when safety is at stake and it’s a core value for us.

2 things that set us apart

  1. Local ownership and management. We’re personally invested in the success of our business, which means we’re personally invested in the success of our clients. In short, we care.
  2. Our major focus is on NZ projects. This manifests itself in our heavy investment in spare parts and skilled technicians to support our customer base. We’re not a retail chain just trying to sell stuff. In short, we care.
