Engineering
HVAC hardened for hazardous and corrosive environments.
Process plants, refineries, terminals and offshore facilities demand HVAC that survives salt-laden air, hydrocarbon atmospheres and 24/7 duty. We retrofit existing units and packages to suit — upgrading materials, coatings, electrical components and controls — so critical control rooms, switch rooms and living quarters stay pressurised, cool and safe.
Built for harsh duty
Corrosion-resistant coils, coatings and stainless hardware for marine and process air.
Hazardous-area ready
Electrical upgrades scoped for the area classification of your site.
Pressurisation you can trust
Positive-pressure control for control and switch rooms, verified on handover.
Scope
