Data Centre Emissions
Solutions
Complete exhaust and emissions control systems that help data centres operate reliably, sustainably and compliantly without compromising performance. From single diesel/gas engines to hyperscale facilities with 200+ engines.
Reducing emissions from data centre diesel & gas engines is no longer optional, it is a core operational and regulatory requirement.

Emission Reduction Systems for new installations
and existing diesel or gas engines
Whether you are commissioning a new data centre or managing an existing diesel/gas engine fleet under tightening emissions regulations, ECI has a purpose-built emission reduction solution designed, manufactured and commissioned by ECI's in-house team.
New Installations
ECI's emission solutions are integrated into a design optimised to your exact engine, fuel type, load profile and emissions requirements.
- Full Tier 4 modular design: SCR + DPF + DOC in a pre-packaged solution, or a pre-packaged MIRA-CUBE solution
- Designed with expandable catalyst rows for future emissions reduction
- Individual diesel engine commissioning to current emission targets
- All-in-One CEMS control panel pre-wired
- Continuous Emissions Monitoring System (CEMS) includes a closed loop system as standard
- Urea dosing, mixing duct, storage and accessories fully integrated
- Full handover documentation, technical training and operation manuals
- Targeted emission compliance available: NOx reduction only, disel particulate matter only, Tier 3 or Tier 4 is avialable
Retrofit to Existing Engines
As Emission Regulation Compliance tightens across Australia and the APAC Region, a retrofit emission solution is a cost-effective path to achieve compliance without replacing the asset.
- Engineered to fit existing exhaust systems with minimal structural modification
- MIRA-CUBE™ unique compact plug-and-play SCR/DPF that installs directly on generator enclosures for 1–4 MW diesel engines
- Compatible with diesel, gas, biodiesel blends, HVO, landfill gas and biogas
- Broad operating temperature range: up to 260°C/500°F
- Global remote monitoring and access to data capture
- Key components in our CEMs are from reputable international suppliers
- Removable maintenance doors for rapid servicing, minimal downtime
- Modular design SCR and/or CDPF to provide a solution where plantrooms or enclosures have limited space
Tier 4 Emissions
Compliance
Environmental regulations continue to tighten across Australia and internationally. Data centre operators increasingly require diesel/gas engines that are capable of meeting the world's most demanding emissions standards.
Advanced SCR and DPF technologies are widely recognised as industry best practice for reducing diesel engine emissions in critical power applications.
ECI supplies advanced Tier 4 systems that significantly reduce:
These technologies enable diesel and gas engines to achieve ultra-low emissions while maintaining the reliability expected from mission-critical facilities.
Although standby generators may only operate during testing or emergencies, they remain a significant source of onsite emissions, and regulators are increasingly focused on compliance.
As demand grows
As demand for AI, cloud computing and digital services accelerates, data centres are under increasing pressure to improve sustainability while maintaining resilience. ECI works with consultants, contractors, diesel/gas engine manufacturers (OEMs) and facility operators from concept through to commissioning.
Compact Integrated Emissions System
Ideal for enclosed plant rooms and packaged generator enclosures, as well as stackable applications. Designed specifically for high-output diesel engines, 1 to 4 MW, MIRA-CUBE™ combines multiple emissions technologies into one compact package.
Available through ECI, a MIRATECH Company.

New and changing emissions laws
are already in effect
Air quality regulations for stationary and off-highway engines are tightening significantly in Australia. If your current engine installation has not been assessed against the current regulatory framework, the time to act is now.
NSW Clean Air Regulation 2022
In force since 16 December 2022, this regulation requires older industrial premises (Groups 3 & 4, operating 1979–1997) to meet significantly tighter NOx limits, a reduction of up to 20% by July 2025 (Group 5) and greater than 70% by July 2030 (Group 6). Applications to retain legacy conditions must be lodged at least 12 months before each deadline. SCR is the primary technology pathway operators are adopting.
Victoria EPA: EP Act 2017 & Air Quality Guidance
Victoria's Environment Protection Act 2017 introduced a General Environmental Duty requiring businesses to manage the risk of harm from their emissions. EPA Victoria's updated air quality guidance (Publication 1961, 2022) sets the assessment framework for all industrial activities involving engine emissions. Operating licences increasingly include tighter, site-specific NOx limits, especially for data centres, hospitals and high-density urban areas.
Australia's Product Emissions Standards
Under Australia's Product Emissions Standards Act 2017, all new non-road engines must meet standards equivalent to US EPA Phase III / Euro Stage V. From July 2021, Euro Stage II engines can no longer be newly supplied. State EPA regulations govern operational NOx limits across the asset's lifetime, often requiring SCR aftertreatment regardless of the engine's original certification tier.
Tier 4 Compliance for Existing Fleets
Tier 4 Final standards require reductions in NOx and PM of approximately 90% relative to pre-Tier 4 engines, increasingly referenced in Australian state EPA regulations. ECI's SCR + DPF + DOC package brings Tier 2 or Tier 3 engines to Tier 4 Final performance through retrofit, without replacing the engine. The MIRA-CUBE™ offers a compact plug-and-play path to Tier 4 Final for 1–4 MW diesel generator sets.
