Keeping operations cool isn’t just about comfort, it’s about efficiency, safety, and reliability. In industries like manufacturing, data centres, healthcare, and events, the wrong cooling system can cost time, money, and even equipment lifespan. That’s where chillers come in.
At Rapid Chiller Rentals, we supply a full range of air-cooled, water-cooled, absorption, packaged, industrial, and very-low-temperature chillers to keep businesses running smoothly. But with so many options, how do you know which is right for you?
Let’s break down the different types of chillers, their key features, and where they shine.
1. Air-Cooled Chillers
Air-cooled chillers use fans to remove heat from refrigerant before releasing it into the atmosphere. They’re a fast, flexible solution when you need cooling without complex infrastructure.
Why choose them:
- Quick to install no cooling towers required.
- Portable ideal for temporary events or short-term projects.
- Perfect for sites with limited water access.
Best used for:
- Emergency cooling
- Seasonal temperature control
- Event cooling for large venues
Fact: According to industry data, air-cooled chillers account for over 50% of chiller installations worldwide because of their adaptability.
2. Water-Cooled Chillers
Water-cooled chillers circulate water to remove heat, typically through a cooling tower. They offer high energy efficiency, especially for large, permanent installations.
Why choose them:
- Lower operating costs for long-term use.
- Quieter than air-cooled systems.
- Handle large cooling loads with ease.
Best used for:
- Manufacturing plants
- Large office complexes
- Hospitals and laboratories
Pro Tip: While water-cooled chillers require more setup, they can be up to 15% more efficient than air-cooled units in the right environment.
3. Absorption Chillers
These clever systems use heat energy instead of electricity to drive the cooling cycle. That heat can come from natural gas, steam, or waste heat from industrial processes.
Why choose them:
- Ideal when electricity is costly or limited.
- Can use waste heat, improving overall site efficiency.
- Low electrical demand.
Best used for:
- Sites with existing steam systems
- Industrial facilities with waste heat
- Renewable energy integration projects
Did you know? Absorption chillers can cut electrical demand by up to 90% compared to traditional chillers.
4. Process Chillers
Engineered for the manufacturing world, process chillers are built to maintain exact temperatures under heavy workloads. Their tight temperature control and long service life make them a must-have for industries like plastic moulding, printing, and metal fabrication.
Key Benefits:
- Designed for continuous operation in demanding environments
- Minimises downtime with robust, reliable performance
- Ideal for processes where even a 1°C fluctuation could impact quality
5. Heat Pump Chillers
Why invest in separate heating and cooling systems when you can have both? Heat pump chillers reverse their cycle to switch between cooling and heating, offering year-round climate control in a single unit.
Perfect for:
- Facilities with seasonal temperature changes
- Reducing energy costs by consolidating equipment
- Applications where space is limited
6. Low-Temperature Chillers
When you need to go well below freezing, low-temperature chillers are the answer. These machines can achieve extreme cooling for:
- Freezer storage
- Deep-cooling in the pharmaceutical sector
- Chemical processes requiring sub-zero conditions
Why it matters: Maintaining these ultra-low temperatures is critical for product integrity, safety, and compliance.
7. Dry Air Chillers
Humidity control is just as important as temperature in certain environments. Dry air chillers provide cool air without increasing moisture perfect for:
- Electronics production rooms
- Archival storage facilities
- Cleanrooms in pharmaceutical manufacturing
8. Fluid Chillers
Instead of cooling air, fluid chillers circulate cooled liquids such as glycol solutions to maintain precise temperatures in sensitive environments.
Applications:
- Laboratories
- Food and beverage processing
- Specialised manufacturing processes

FAQs
1: What’s the main difference between air-cooled and water-cooled chillers?
Air-cooled use fans and require no water. Water-cooled use cooling towers and offer better long-term efficiency.
2: Are absorption chillers eco-friendly?
Yes, especially when they run on waste heat or renewable energy.
3: Can I hire a chiller for just a weekend event?
Absolutely, our packaged chillers are perfect for short-term hire.
4: What temperature can VLTC chillers reach?
They can go as low as −40°C, depending on the model.
5: How quickly can you deliver?
In emergencies, we can often deliver same-day nationwide.
