Our Technical Solutions. Led by Efficiency.
Engineering the bridge between boardroom strategy and operational reality.

A full-lifecycle partner for Australasia’s energy transition.
Many advisory firms can write a high-level sustainability report, but very few have the technical capability to physically deliver those solutions on-site.
Navigating the energy transition requires a partner who understands the intersection of financial CapEx planning and complex engineering realities. At DETA, our consultants work seamlessly with our engineers to bridge the gap between boardroom targets and daily operations. Whether you are optimizing a utility network, decarbonising a healthcare campus, or increasing industrial yield, we provide the technical precision to execute on time, on budget, and without disrupting your core services.
Our Engineering & Energy Transition Services
Process Optimisation Engineering
MMaximise throughput and minimize waste. We deploy deep technical engineering to debottleneck systems, recover thermal energy, and ensure you are getting maximum output for every dollar of energy spent. From heat pump integration to refrigeration optimization, we make your existing assets work harder.
Energy Audit & Management
Protect your margins from volatile energy markets. As Australasia's leading efficiency experts, we deliver investment-grade energy audits and management programs. We identify operational waste, unlock government co-funding, and provide the data required to permanently lower your OpEx.
