Choosing the Right Temporary Cooling Solution
When temperatures rise or cooling systems fail, businesses often need a fast and reliable way to maintain comfortable working conditions.
Two of the most common temporary cooling solutions are portable air conditioning units and evaporative coolers. While both are designed to reduce temperatures and improve comfort, they operate differently and are suited to different environments.
Understanding the difference between the two can help businesses choose the most effective and cost-efficient cooling solution for their site.
At Ideal Heat Solutions, we provide portable air conditioning hire and evaporative cooler hire across the UK, supporting commercial, industrial and temporary applications nationwide.

What Are Portable Air Conditioning Units?
Portable air conditioning units provide refrigerated cooling by actively removing heat from the air. These systems are ideal for enclosed indoor environments where controlled temperature reduction is required.
Our portable air conditioning fleet ranges from 3.2kW to 7.3kW, offering flexible cooling solutions for a wide range of commercial and industrial applications.
Portable AC units are commonly used in:
- Offices and meeting rooms
- Server rooms and IT environments
- Healthcare facilities
- Retail spaces
- Temporary cabins and welfare units
- Hotels and hospitality venues
Because the units are portable, they can be positioned quickly and relocated as site requirements change.

The Benefits of Portable Air Conditioning Hire
Portable air conditioning units offer several key advantages:
Reliable Temperature Control
Portable AC units provide consistent, controlled cooling, making them ideal for environments where maintaining a stable temperature is essential.
Fast Deployment
Units can be delivered and operational quickly, helping businesses respond rapidly to breakdowns or seasonal demand.
Flexible and Portable
The units can easily be moved between rooms or different areas of a site as cooling requirements change.
Suitable for Temporary Applications
Hiring portable air conditioning removes the need for permanent installation and long-term investment.
What Are Evaporative Coolers?
Evaporative coolers work differently from portable air conditioning units. Instead of refrigerated cooling, they use water evaporation to reduce air temperature.
Warm air passes through water-saturated cooling pads, creating cooler airflow that is distributed throughout the space.
Evaporative coolers are particularly effective in large, open or well-ventilated environments where traditional air conditioning may be less practical.
Typical applications include:
- Warehouses
- Workshops
- Factories
- Marquees and event spaces
- Loading bays
- Outdoor or semi-outdoor environments

The Benefits of Evaporative Cooler Hire
Energy Efficient Cooling
Evaporative coolers generally consume less electricity than traditional air conditioning systems.
Ideal for Large Open Spaces
They are highly effective in large areas where enclosed air conditioning would be difficult or expensive to implement.
Cost-Effective Temporary Cooling
Evaporative coolers provide an economical cooling solution for industrial and event applications.
Portable and Easy to Position
Like portable AC units, evaporative coolers can be deployed quickly and repositioned where needed.
Which Cooling Solution Is Best for Your Site?
The right cooling solution depends on the environment and operational requirements.
Portable air conditioning units are typically best for enclosed indoor environments where precise temperature control is important.
Evaporative coolers are generally better suited to larger ventilated spaces where airflow and energy efficiency are priorities.
In some cases, a combination of both solutions may provide the most effective cooling strategy across different areas of a site.
Temporary Cooling for Commercial and Industrial Applications
Temporary cooling hire plays an important role across many sectors.
In offices, retail environments and healthcare facilities, portable air conditioning helps maintain comfortable working conditions and protect sensitive equipment.
In industrial environments, evaporative coolers help improve airflow and reduce heat build-up in larger operational spaces.
Temporary cooling is also widely used during:
- HVAC maintenance works
- System failures and emergencies
- Seasonal demand increases
- Construction and refurbishment projects
- Events and temporary structures
