Wellington Fan Packs: How one modular range is transforming OEM operations

Written by AoFrio | Oct 3, 2025 12:23:45 AM

Commercial refrigeration OEMs today balance high-performance cooling requirements with increasingly complex operational demands. As market pressures intensify for time-to-market and cost optimization, procurement teams coordinate dozens of motor-blade combinations while engineering teams validate numerous configurations. 


Wellington Fan Packs offer a strategic solution: one modular family that dramatically reduces SKU counts, streamlines procurement, and accelerates design cycles without sacrificing performance. 

 

Why SKU rationalization matters for OEMs 

SKU rationalization matters for OEMs because they operate on tight margins and compressed development timelines. Every additional part number carries operational cost: inventory management complexity, supplier coordination overhead, and extended qualification timelines. SKU reduction translates directly into measurable operational improvements: 

  • Lower inventory costs, reduced stockout risk and simplified reorder management 
  • Streamlined supplier relationships and faster procurement cycles 
  • Shorter design validation timelines and fewer engineering change orders 

Wellington Fan Packs consolidate multiple motor-blade variants into a cohesive modular range, delivering immediate operational savings and enabling teams to focus on innovation rather than component logistics. 

 

One range, eight configurations  

At the heart of this simplification are two ECR® 2 motor power ratings (13W and 26W) paired with four fan diameters (7", 8", 9", 10"). This provides eight pre-engineered assemblies that cover most refrigeration cabinet applications: 

  • Comprehensive airflow coverage from 450 m³/h to 1,200 m³/h 
  • Universal voltage compatibility (100–240V) for global deployment 
  • Total speed flexibility: preset speeds and custom programming option 
  • IP67 ingress protection for demanding environments 
  • Standardized dimensions for straightforward integration 
  • Custom connector: pluggable cable with length and plug type to suit your application 

Rather than managing dozens of individual SKUs, procurement teams work with just eight part numbers, a substantial reduction in complexity compared to traditional sourcing approaches. 

 

Streamlined procurement operations 

Wellington Fan Packs' modular architecture transforms procurement workflows: 

  • Single-supplier sourcing replaces multi-vendor coordination 
  • Consolidated part numbers reduce carrying costs and simplify inventory management 
  • Universal specifications eliminate regional variants 
  • Standardized documentation accelerates order processing 

This operational efficiency allows OEMs to respond more rapidly to market demands while reducing supply-chain complexity and costs. 

 

Accelerated engineering without compromising selection 

Wellington Fan Packs come equipped with features and support to help your design engineers achieve faster development cycles: 

  • Complete specifications and airflow performance data, including comparison with existing solutions 
  • Programmable motor for rapid speed adjustments to streamline development 
  • Local engineering support to accelerate complex projects 
  • Large range of safety compliance approvals 
  • Integrated motor-blade design, minimising component selection and testing 

These capabilities can reduce typical fan-assembly qualification timelines while maintaining the flexibility to select optimal configurations for each application. 

 

Proven Performance and Reliability 

Wellington Fan Packs deliver superior performance backed by real-world deployment: 

  • 10-year design life supported by comprehensive testing 
  • Over 17 million ECR motors installed globally 
  • 74% motor efficiency  
  • Advanced aerodynamic design for ultra-quiet operation 

The integrated approach reduces service requirements and supports lower total cost of ownership for OEM customers.
