Full-Service Chiller Hire for Commercial & Industrial Sites
Cross Rental Services provides temporary chiller hire for planned maintenance, contingency cover and emergency cooling failure. Single units from 5kW to 750kW, with multi-megawatt packages available for larger process sites and comfort cooling loads. Our F-Gas certified engineers install and commission every unit. Free site survey where required.
Chiller Hire Range
Our chiller hire range offers solutions from single units to multi-megawatt capacities, with options covering 5kW to 750kW. Designed to handle temperatures from +20°C to -10°C. Chillers come equipped with integral pumps, tanks, flow switches, Bauer couplings and control gauges to ensure full flexibility and control.
Dry Air Coolers
High-capacity dry air coolers for large-scale industrial and commercial applications. Using energy-efficient refrigerants compliant with the Clean Air Act. Options from 250kW to 1MW, run in parallel for multi-megawatt packages, provide free cooling, requiring only the power input for the fans to operate.
Heat Pump Chillers
Efficient heat pump chiller solutions for heating and cooling simultaneously. Units switch from heating to cooling depending on the ambient temperature, reducing energy consumption and operational costs across your site.
Air Handling Units
Enhance your overall climate control with our efficient air handling units, designed to work seamlessly with our chiller systems. Use them standalone or with a chiller, and pair with ducting to form a complete packaged system, for data centres, warehouses and large commercial floorplates.

Contingency Planning
For mission-critical cooling, preparation matters. We help you plan for failure before it happens. Preparing your site so replacement chillers can be deployed quickly to minimise downtime and get your operations back online faster. Protecting production, processes and business continuity.
Cross Rental Services works with you in advance to build a contingency plan around your site and cooling requirements. By identifying the equipment, connections and installation in advance, we can reduce delays when a breakdown occurs and help restore your cooling sooner.
- Pre-agreed response plan, with equipment and installation requirements documented, so it can be deployed quickly when a breakdown happens
- Site surveyed and prepared in advance, with connections and enabling works identified.
- Agreed costs quoted ahead of time, and single point of contact for activation
- 24/7 emergency response and engineering support.
Our chiller hire commitment
Long-Term & Contract Chiller Hire
For pharmaceutical, manufacturing, data centre and process cooling applications that need a stable, ongoing cooling solution, our longer-term contract chiller hire provides cost certainty and full service support.

Got a question?
Frequently Asked Questions
What size chiller do I need?
Sizing depends on cooling load, application (process or comfort cooling) and your site's existing connections. Our engineers carry out a free site survey to confirm the right unit for your kW requirement.
What if the size I need isn't in your standard range?
Our engineers can design a bespoke solution to meet your exact requirement - whether that's sourcing a larger single unit or engineering a multi-unit configuration to match your site's specific load.
How quickly can you deliver equipment?
Getting equipment to site within 24 hours is our goal, where feasible, subject to unit availability and site access. For urgent cooling failures, call our team directly. (link to click to call)
Is your chiller hire F-Gas certified?
Yes. All installation and service engineers are F-Gas certified.
Can a chiller connect to our existing AHU or pipework?
Yes. Our chillers are supplied with the ancillaries needed to connect to AHUs, fan coils or existing site pipework for rapid deployment.
Do you offer emergency chiller hire?
Call our 24/7 support line. Our engineers provide breakdown response for reactive and emergency cooling failure.
Can I hire a chiller long-term?
Alongside short-term and emergency cover, we support longer-term contract chiller hire for pharma, process cooling, manufacturing and data centre applications, including SLA-backed maintenance and a dedicated account manager for contracted customers.

Case Studies
7 February 2026
Three-Hour Turnaround for an Essential Hospital Chiller
An MRI scanner lost cooling with zero notice — no time for a site visit. Our engineers sized a 14kW chiller by phone, Hiab-lifted it onto the hospital roof, and had scans running again within three hours of the call.

Solving Gearbox Overheating for Continuous Production at a Plastics Moulding Company
A plastics moulding line was stopping every few hours to cool an overheating gearbox — until we isolated it on its own dedicated 30kW chiller loop, complete with pump, tank and bypass. The line has run 24/7 ever since.

Long Term Chiller Hire Supports Wastewater Treatment Plant
Ageing chillers at a wastewater treatment plant were surveyed, delivered and installed within 48 hours of the first call. Ten years and one contract renewal later, the same relationship is still running the plant's process cooling today.
