Heat Pump Chiller Hire

About HVAC Chiller Hire

Hire 1kW units to 10,000kW for immediate nationwide delivery. All our HVAC hire chillers contain Zero ozone depleting refrigerants.

Aqua Cooling exist to help you keep your air conditioning on line and working as efficiently as possible, including within the planned parameters you need to maintain your set building temperatures and data conditions.

HVAC chiller hire means you can mitigate a shortfall in cooling capacity, a planned chiller changeover or when you might need to add a temporary N+1 contingency. Whatever the reason, our hire department is equipped to support your business.

They will be able to provide you with a face-to-face technical assessment, equipment recommendation and practical method of working safely with you and your team on site.

It’s Never Been Easier To Hire or Rent Heat Pump Chillers

Ideal for HVAC and temporary air conditioning applications where weather conditions are changeable. Or where heat is required throughout the evening, night time and early morning, before air conditioning is needed throughout the day to deal with high ambient conditions.

Special note: The hot water leaving temperatures generated are ambient dependent and generally perform to this design standard in ambient temperatures above -10oC.

Low GWP Refrigerants - The Detail

Refrigerant Selection & GWP Table

This table shows the GWP of the standard refrigerants used in process chillers, compared to the lower GWP refrigerants such as R32, R454b and R290.

The efficiency, cost and capital purchase figures are all in relation to R410a, for example, R32 is 7% more efficient at cooling than R410a, and is over 50% cheaper. The ongoing energy efficiency savings will outweigh the increased capital purchase over time as well as being better for the environment.


Some frequently asked questions

Chillers normally operate on fluorinated gases, often referred to as refrigerants. These are controlled by F-Gas regulations, to reduce emissions and to protect the environment. Chillers use a variety of refrigerants – or gases – but some have been phased out by legislation in favour of those with a lower global warming potential (GWP). Popular refrigerants in chillers include R-410A, R-134a, R-407C, R454B, R32, R1234ze, R513A, R-290 (propane), R-717 (ammonia) and R-744 (Carbon Dioxide).

GWP stands for Global Warming Potential and in terms of refrigeration gases – its potential as a greenhouse gas by comparing it to CO2.


GWP of CO2:1

Every 1kg of R410a is equivalent to 2088kg of CO2

The refrigerant you choose can have an important effect on the energy efficiency of your chiller, the capital cost, operative costs and your green credentials.

Common refrigerants have risen in price by as much as 300% in recent times because they are not as environmentally friendly as alternatives.

The EU is phasing down the availability of HFCs by 79% between 2015 and 2030. This is the most crucial aspect of the F Gas regulation and affects all end-user markets.

In January 2020, the phase-down included a ban on new equipment with refrigerants with a GWP of >2500. On 1st January 2030, there will be a ban on the use of refrigerants, recovered, reclaimed and/or recycled with GWP>2500 for service and maintenance.

By 2030, only 21% of HFCs sold in 2015 will be available.

If you’re choosing a new chiller now, it’s important to consider all these aspects to future proof your plant and minimise the impact on the environment.

How do Cooling Towers work?

Cooling towers are effectively an organic heat exchanger. Warm or hot water from a process is cooled by passing it through the tower and back out again into the process.

A cooling tower enables the water to meet the air so that some of the water evaporates, lowering the overall water temperature.

Water is pumped – usually from either the basin of the tower or a sump tank below the cooling tower – through pipework to the process. This then returns to the cooling tower. The water is either sprayed by nozzles onto the fill media (counterflow) or returns to a top tank to gravity drain onto the fill media. This part of the process maximises air to water contact. The water flows over the fill media – or packing – meeting the air which is pulled (induced draft) or pushed through (forced draft) by a fan. This is referred to as evaporative cooling.

Aqua’s temperature control expertise can help you.

We step in when you need a helping hand.

Equipment Failure

We can deliver a temporary heat pump chiller and connect it quickly to keep your business operating. Your existing kit can then be repaired and fully tested under no duress before being reinstated, reducing risk and downtime.

Supplementing Existing Equipment

We can add cooling and heating capacity to your existing system and help optimise production, reduce bottlenecks, provide N+1, or help supply additional seasonal demand.

Planned Shutdowns & Outages

A pre-planned approach to delivery of suitable equipment can be managed to help mirror your needs during site maintenance.

New Projects & Production Lines

Aqua can create bespoke rental packages that can be delivered to fully meet the needs of your planned R&D, NPD testing and localised indoor production process requirements.

No Capital Budget
