Progress continuing at Coles Caringbah Pavilion 👷‍♂️❄️

Our HVAC team has been busy onsite completing several key lifts and installations as the project continues to take shape. Recent works have included telehandler and rigging operations for the generator, gyprock & studs, Meridian boiler, 50mm ICP panels, AirChange AHU, GJ Walker AHU, and the electrical switchboard.

Great to see the plant and services coming together as we move closer to the next stage of the build. Strong teamwork across the crews to safely coordinate these lifts and installations.

🚧 Project Update – Woolworths Melonba

We’re excited to share our first project update as works get underway on the new Woolworths store at Melonba, NSW.

This development will deliver a brand-new supermarket and retail precinct to support the rapidly growing Melonba community. Our team is proud to be delivering the mechanical HVAC installation for the project.

This week we reached an important milestone with the delivery and installation of the main GJ Walker Air Handling Unit (AHU) — completed on the same day thanks to great coordination between our team, suppliers, and cranage crew.

The unit installed is:
• 1 x Air Handling Unit (AHU) – 12,000 L/s supply air including high pressure CO₂ coils

This system will play a key role in providing efficient ventilation and climate control for the store.

A big thank you to everyone involved in making the lift and installation run smoothly and safely. Looking forward to sharing more progress as the project continues.

Another perspective on a big lift onsite 💪❄️

This time-lapse reel captures the installation of the CO₂ gas coolers for this project — a key milestone in the refrigeration system. Moves like this require detailed planning, precision lifting, and strong teamwork to safely position equipment of this scale.

Great effort from the team as the project continues to progress.

Project spotlight: Coles Woy Woy 🚧🏗️

We’re proud to be delivering a major HVAC upgrade at Coles Woy Woy, replacing existing plant with a new high-efficiency mechanical system designed to improve performance, reliability and long-term sustainability.

This week marked a key milestone with the crane lift of the Carrier chiller and Revere CO₂ heat pump safely into position.
The scope of works on this project

includes:
• New air handling unit (AHU)
• Carrier chiller and CO₂ heat pump installation
• New pumps, expansion tanks and dosing systems
• VRV systems
• Full chilled water pipework installation
• Supply and return air ductwork upgrades
• Electrical upgrades including new MSSBs
• Controls and BMS integration
• Testing, balancing and full commissioning

The inclusion of the CO₂ heat pump is a deliberate sustainability decision. Using R744 refrigerant (GWP of 1), it offers a significantly lower environmental impact compared to conventional high-GWP systems — supporting more responsible, future-focused plant selection.

Great planning, tight coordination and a strong safety focus ensured a smooth lift and another step forward in delivering this upgrade.
Looking forward to bringing this system online.

Another successful refrigeration upgrade delivered at Coles Supermarkets – Chipping Norton ✅

We recently completed a full glass door freezer replacement along with the installation of a Refrigerant Leak Detection System (RLDS), enhancing efficiency, safety, and overall system performance.

The outdated freezer cases were replaced with modern, energy-efficient glass door units designed to:
• Improve product visibility
• Maintain optimal temperature control
• Reduce operating costs
The result is a refreshed in-store presentation, an improved customer shopping experience, and stronger long-term energy performance.
As part of the upgrade, we also installed a Refrigerant Leak Detection System (RLDS) to ensure environmental compliance and operational protection. The system provides:
• Continuous monitoring
• Early leak detection
• Real-time alerts
• Reduced refrigerant loss
• Minimized downtime

This comprehensive upgrade delivers improved reliability, regulatory compliance, enhanced energy efficiency, and peak operational performance — all while maintaining the highest safety standards.
Proud to support Coles in delivering sustainable, high-performing retail environments. ❄️
