Belmont Fan Industry Solution Case Study

Assisting European HVAC Manufacturer R.C. in Upgrading Air Handling Unit (AHU) Fan Systems

Project Background & Client Information

Client Name: R.C. (A leading HVAC system manufacturer in Europe, specializing in Air Handling Units)

Industry: Heating, Ventilation, and Air Conditioning (HVAC)

Region: Europe

Customer Pain Points & Challenges

R.C. had been using EC centrifugal fans from the well-known brand E***, and while the product quality was reliable, the company faced several critical challenges:

● Unstable supply chain: Irregular delivery times disrupted production schedules

● High procurement costs: Expensive unit prices limited overall project profitability

● Urgent need for a reliable, cost-effective alternative without compromising performance

● The replacement fan needed to meet or exceed the following technical specifications:

Airflow: approx. 8661 m³/h

Static Pressure: 1500 Pa

Desired enhanced energy efficiency and compatibility with smart control systems to reduce long-term operational costs
