How to Choose the Right Cellar Cooling System for Your Business

For businesses that store beer, wine, and other temperature-sensitive beverages, maintaining the right storage conditions is essential. Without proper temperature control, drinks can lose their flavour, spoil quickly, or develop carbonation issues.

A cellar cooling system helps maintain consistent temperatures and humidity levels, ensuring beverages remain fresh, properly aged, and safe for consumption. Choosing the right cooling system depends on factors such as cellar size, insulation, beverage type, and energy efficiency.

This guide explains how to select the best cellar cooling system for your business, ensuring quality, compliance, and long-term cost savings.

Why Businesses Need a Cellar Cooling System

Without proper temperature regulation, beverages can suffer from:

✔ Flavour degradation – Exposure to fluctuating temperatures affects taste.
✔ Excess foaming in beer – Improper cooling leads to carbonation loss.
✔ Wine spoilage – Oxidation causes bitterness and loss of aroma.
✔ Increased waste and financial loss – Spoiled stock reduces profit margins.

A cellar cooling system ensures beverages are stored at their ideal temperature:

• Cask ales: 11°C to 13°C
• Keg beers: 3°C to 6°C
• Red wine: 12°C to 15°C
• White and sparkling wine: 7°C to 10°C
• Soft drinks: 3°C to 7°C

Maintaining stable conditions ensures beverages retain their intended taste and quality, reducing waste and operational costs.

Key Factors to Consider When Choosing a Cellar Cooling System

1. Size and Layout of Your Cellar

The size and shape of your cellar influence the type of cooling system required.

✔ Small cellars – A through-the-wall or monobloc system is ideal.
✔ Medium-sized cellars – A split cooling system provides better airflow.
✔ Large commercial cellars – Ducted systems offer even temperature distribution.

A professional assessment helps determine the best system for your storage space.

2. Temperature Requirements for Different Beverages

Each beverage requires a specific temperature range to maintain quality. A multi-zone cooling system allows you to store different types of beverages at separate temperatures.

✔ Mixed storage – A system with adjustable temperature settings is best.
✔ Dedicated beer storage – A keg-specific cooler maintains carbonation.
✔ Wine cellars – Temperature stability is crucial for proper ageing.

A properly designed cooling system prevents inconsistent cooling and beverage damage.

3. Type of Cooling System

There are three main types of cellar cooling systems, each with its advantages.

Through-the-Wall Cellar Coolers

✔ Compact and easy to install.
✔ Best for small cellars or residential use.
✔ Self-contained unit with no external components.

Split Cellar Cooling Systems

✔ Consist of an evaporator inside and a condenser outside.
✔ Suitable for medium to large cellars.
✔ Quieter operation compared to monobloc units.

Ducted Cellar Cooling Systems

✔ Ideal for commercial setups and wine storage.
✔ Even distribution of cold air across large areas.
✔ No visible cooling unit inside the cellar.

The right system depends on cellar size, beverage type, and ventilation requirements.

4. Energy Efficiency and Operating Costs

A high-quality cellar cooling system should be energy-efficient to reduce operational expenses.

✔ Smart thermostats – Help adjust cooling levels based on demand.
✔ Eco-friendly refrigerants – Reduce environmental impact.
✔ Insulated cellar walls – Prevent energy loss and improve efficiency.

Choosing an energy-efficient model helps lower electricity bills while maintaining stable temperatures.

5. Noise Levels and Location

✔ Restaurants and pubs need quiet operation to avoid disrupting customers.
✔ Ducted systems are quieter than through-the-wall and split units.
✔ Proper ventilation prevents the system from overworking and producing noise.

The right placement and soundproofing options ensure a comfortable environment.

6. Maintenance and Servicing Requirements

✔ Regular filter cleaning prevents dust buildup.
✔ Annual servicing ensures optimal performance.
✔ Refrigerant checks prevent leaks and efficiency loss.

A well-maintained system lasts longer and operates more efficiently, reducing long-term costs.
