We keep New Zealand's ammonia plants, coolstores and fuel facilities safe and compliant. Hazardous-area surveys, classification, EEHA inspection and verification dossiers — delivered by specialists with 20 years' experience, backed by the full electrical capability of NZ Electrical Solutions.
Protect your plant. Protect your people. Protect your profits.
Classifying and certifying explosive atmospheres is a discipline of its own. We focus on it — so you get a documented, defensible compliance position that stands up to insurers, auditors and councils.
Survey → classification → design/upgrade → independent inspection & sign-off → verification dossier. No handoffs between surveyor, electrician and inspector.
Ammonia refrigeration, oil & gas, flour and milk-powder dust, bitumen and methanol. We've worked the environments most contractors won't touch.
Everything mapped to AS/NZS 60079, EEHA and IECEx/Ex — with the paperwork to prove it when your insurer or council asks.
The full weight of a 50-strong national industrial electrical team — and 24/7 site support — behind every inspection and upgrade.
Pick your environment — the process is the same rigorous path to a signed-off, dossier-backed result.
Coolstore and refrigeration ammonia systems — compliance, gas detection and the documentation councils and insurers now expect.
