Introduction
If you’re trying to choose the right chiller you’ll know it’s not as simple as picking the cheapest option and hoping for the best. Cooling is critical whether it’s for food storage events manufacturing or simply keeping your workplace comfortable. The wrong decision can cost you money energy and downtime. At Rapid Chillers, we’ve seen first-hand how the right unit saves businesses thousands every year.
This guide will help you cut through the jargon and pick a chiller that works for your site your budget and your long term goals.
1. Start with the Numbers Sizing Matters
The first step is to calculate your cooling requirement. If your chiller is too small it will constantly run at maximum capacity wearing itself out quickly. Too large, and you’ll waste energy and money.
- Heat load calculation: Work out how much heat your process or space generates for example, a factory producing plastics may require upwards of 200 kW of cooling while a small office might only need 20–30 kW.
- Build in a buffer: We recommend adding 10–20% extra capacity. This ensures your chiller can handle hot summer days or unexpected demand spikes.

2. Air-Cooled vs Water-Cooled Which Suits You Best?
Not all chillers are built the same. The two most common types are:
Air-cooled chillers
- Simple to install and move
- No need for a water source
- Perfect for temporary hire or emergency cooling
- Slightly noisier in operation
Water-cooled chillers
- More energy-efficient in the long run
- Quieter making them great for offices or events
- Require cooling towers and regular water treatment
- Longer lifespan typically 20–30 years with care
Quick stat: According to Engineering Toolbox water-cooled chillers can be 10–15% more energy efficient than air-cooled units especially for continuous operation.
3. Think About Your Site
Your site plays a huge role in the decision:
- Space: Air-cooled chillers are more compact perfect if you’re tight on room.
- Noise restrictions: If you’re based in a city or residential area water-cooled options may be quieter.
- Installation access: Rapid Chillers can deliver units with Hiab trucks and even cranes if access is tricky.
- Water availability: A reliable water supply is essential for water-cooled models.
4. Look Beyond the Upfront Cost
When businesses compare chillers, it’s tempting to focus on the hire or purchase price. But running costs often matter more over time.
- Maintenance: Water-cooled systems require more upkeep but they last longer.
- Sustainability: With the UK pushing towards net-zero greener equipment could help you meet future compliance rules while also lowering costs.
