Food Retailer

ALDI Ireland

ALDI Ireland operates a nationwide network of high-volume food retail stores with a strong focus on efficiency, consistency, and sustainability.

Cross Refrigeration delivered a nationwide retail refrigeration upgrade programme, supporting ALDI’s transition to natural refrigerant technology across multiple sites.

Client Challenge

ALDI required a large-scale upgrade to replace legacy HFC refrigeration systems while maintaining operational consistency across its estate.

The programme needed to address several critical operational and environmental requirements:

Reducing energy consumption and carbon impact
Delivering consistent system performance nationwide
Managing upgrades across multiple live trading stores
Ensuring repeatable quality and compliance at every site
Coordinating delivery without disrupting store operations

The scale and complexity of the rollout demanded a partner with proven national capability.

Our Solution

CO₂ refrigeration plant upgrades

Cross designed and delivered a standardised upgrade approach using high-efficiency CO₂ refrigeration plant.

This included the following core elements:

Replacement of legacy HFC systems
Installation of modern CO₂ plant and integrated controls
Optimised system design for efficiency and performance
Standardised specifications across all sites

This ensured long-term compliance and consistent system behaviour.

Nationwide programme delivery

To deliver the rollout at scale, Cross applied its established nationwide delivery model.

This approach focused on control, consistency, and coordination:

Central programme scheduling across regions
Deployment of experienced engineering teams nationwide
Consistent installation and commissioning standards
Central oversight and quality assurance

All work was completed while stores remained operational.

Service and lifecycle support

Following installation, Cross provided full service and maintenance support to protect system performance.

Ongoing support includes:

Planned preventative maintenance
Performance monitoring and optimisation
24/7/365 nationwide emergency response

This ensures system reliability throughout its operational life.

Outcome

ALDI partnered with Cross for its proven technical leadership and ability to deliver consistently at a national level.

Key to the decision was Cross’s leadership in CO₂ and natural refrigerant systems, strong project governance and quality control, and an end-to-end approach covering everything from upgrades to ongoing service, all supported by reliable 24/7 nationwide support.

The programme delivered clear operational and sustainability benefits across the ALDI estate. Upgraded stores achieved significant energy savings and a reduced carbon footprint through the use of natural refrigerants, alongside consistent refrigeration performance and standardised quality nationwide, supporting long-term compliance and operational resilience.
