Case Study

Brewery Chiller Installation – Engineered Supply & Install

A growing UK brewery required a properly engineered brewery chiller installation to support increased fermentation capacity and stabilise temperature control across multiple vessels. Evolution Cooling Ltd delivered a full supply and install solution centred around a 130kW industrial air-cooled chiller operating on a pressurised 33% MPG glycol system set to -5°C.

The installation provided a stable, scalable cooling platform aligned with long-term production growth and operational reliability.

The Challenge

As production volumes increased, the existing cooling arrangement approached its operational limits. Peak demand periods exposed risks of temperature instability across fermentation vessels, particularly during simultaneous loading.

In brewery environments, even minor temperature deviation can affect:

  • Yeast performance

  • Fermentation speed

  • Flavour profile consistency

  • Final product quality

The client required additional cooling capacity capable of maintaining tight temperature tolerances under variable production loads.

Key project constraints included:

  • Limited plant space

  • Live production environment during installation

  • Requirement for even hydraulic distribution across multiple tanks

  • Need for freeze protection without compromising efficiency

  • Future expansion capability

Cooling infrastructure had to be engineered around real operational load data rather than nominal kW ratings.

During the project lifecycle, commercial circumstances evolved. Ensuring system stability and protecting the installed infrastructure became critical to maintaining uninterrupted production.

The Solution

Brewery Chiller Installation – The Engineering Approach

Evolution Cooling Ltd designed and installed a dedicated brewery process cooling system engineered for stability and scalability.

The system was built around:

  • 130kW industrial air-cooled chiller

  • Pressurised primary glycol circuit

  • 33% mono propylene glycol concentration

  • Operating setpoint of -5°C

  • Balanced distribution to fermentation vessels

The 130kW capacity was selected based on simultaneous fermentation load calculations, vessel heat rejection requirements and peak ambient conditions.

A pressurised glycol system was specified to improve hydraulic stability, reduce the risk of air ingress and maintain consistent flow rates under variable load conditions.

The 33% MPG concentration provided appropriate freeze protection below the -5°C operating setpoint while maintaining thermal efficiency and suitable viscosity for pump performance.

Installation works included:

  • Chiller positioning and connection

  • Glycol circuit installation

  • Pump sizing and hydraulic balancing

  • Integration with existing pipework

  • Electrical connection and control interface

  • System charging and commissioning

Commissioning was completed under live load conditions to validate stable temperature performance across multiple fermentation vessels operating simultaneously.

Where commercial complexity arose during the project timeline, Evolution Cooling Ltd retained technical responsibility and ensured system integrity and operational continuity were maintained.

Key Highlights Of The Solution

✅ Full design, supply and installation responsibility

✅ 130kW industrial air-cooled chiller

✅ Pressurised 33% MPG glycol system

✅ -5°C operating setpoint for fermentation control

✅ Hydraulic balancing across multiple vessels

✅ Commissioning under live production conditions

✅ Scalable configuration to support future expansion

Project Outcome

The Impact

Following installation, the brewery achieved:

  • Stable and repeatable fermentation temperature control

  • Improved batch consistency

  • Reduced risk of temperature-related product variation

  • Increased production headroom

  • Greater confidence during peak demand periods

The pressurised glycol configuration delivered improved system stability, particularly under simultaneous vessel loading.

Rather than simply increasing nominal capacity, the project established a structured cooling platform aligned with long-term production strategy and quality control.

Cooling infrastructure now supports growth instead of limiting it.

Conclusion

This project demonstrates Evolution Cooling Ltd’s capability to deliver engineered brewery chiller installations from specification through to commissioning while protecting operational continuity.

With a 130kW chiller, pressurised 33% MPG glycol circuit and -5°C operating setpoint, the system provides stable fermentation temperature control and scalable performance for continued expansion.

In process-driven environments, cooling must be engineered correctly. When it is, it becomes a foundation for product consistency, operational confidence and sustainable growth.
