Overview
Client: Food manufacturing company
Location: Suffolk
Industry: Food production – non-contact compressed air application
Solution: 75kW Variable Speed Drive rotary screw air compressor with performance data logging and food-grade compliance
A Suffolk-based food manufacturer required an urgent and efficient replacement for a failed fixed speed compressor. Following detailed monitoring and analysis, Avelair supplied and installed a 75kW Variable Speed Drive (VSD) air compressor, delivering improved reliability, energy efficiency and compliance with food industry best practice.
The challenge
The client’s existing fixed speed compressor had suffered a seized airend, causing operational disruption and highlighting the risks of ageing equipment.
The business required:
- A reliable and immediate replacement solution
- Improved energy efficiency
- Compliance with food industry guidance
- Confidence in long-term performance
Given the variable nature of production demand, it was critical to understand actual compressed air usage before specifying new equipment.
The solution – data-led upgrade to 75kW VSD technology
Avelair installed data logging equipment to monitor:
- Electrical consumption using a clamp meter on the incoming phase
- System pressure via an in-line pressure transducer
- Performance readings at five-second intervals
Detailed analysis confirmed that air demand fluctuated significantly, making a VSD compressor the most efficient solution.
Installed system included:
- 75kW Variable Speed Drive rotary screw air compressor
- Inverter-controlled motor to match output with demand
- Food-grade lubricant, in line with guidance from the British Compressed Air Society Food Grade Code of Practice
Although the compressed air application was non-contact, the use of food-grade lubricant ensured additional protection and compliance with industry standards.
The results
Improved energy efficiency
The VSD compressor adjusts motor speed in real time, reducing wasted electricity and lowering operating costs.
Increased reliability
The new 75kW system provides dependable performance, eliminating the risk associated with the failed fixed speed unit.
Food industry compliance
Operating with food-grade lubricant supports best practice within food manufacturing environments.
Data-driven investment
The installation was based on detailed usage monitoring, ensuring the compressor was correctly sized and optimised for long-term efficiency.
