Why CRS
Benefits of hiring chillers from us
From 5 kW portable units to 1 MW packaged chillers, our fleet covers process cooling, comfort cooling and low-temperature applications. Whatever the duty, we have a unit ready to ship.
Every hire starts with a conversation about your site. We size the plant, plan the pipework and power, and design a temporary system that fits around your operation rather than the other way round.
Our team of fully qualified engineers operates nationwide, both in the field and from our depots. Each engineer is highly experienced and holds the necessary certifications, including Gas Safe registration for gas installations and OFTEC accreditation for oil systems. This guarantees expert service and adherence to all relevant safety and industry standards.
CRS is ISO 9001, ISO 14001 and ISO 45001 certified, F-Gas registered and a member of the Hire Association Europe. Documentation for every unit is available on request.
Breakdowns do not keep office hours. Our support line is staffed around the clock and an engineer can be on site or a replacement unit on the road within hours.
With depots across Ireland and the UK we deliver to city centres, remote sites and everything in between, and our engineers know the local requirements at each.

Frequently Asked Questions
How quickly can you deliver equipment?
Most hire equipment is delivered within 24 hours of your order being confirmed. For urgent breakdowns our emergency team can usually have a temporary unit on site the same day.
Do you install the equipment as well as deliver it?
Yes. Our engineers deliver, position, connect and commission every unit, then show your team how to operate it before they leave site.
What is the minimum hire period?
There is no minimum. Hire runs by the day, week or month, and long-term contracts are priced accordingly.
Can you supply fuel and power for temporary heating?
We can supply fuel management, generators and distribution as part of a complete package, or work alongside your existing site services.
Is your equipment suitable for food and pharmaceutical environments?
Our refrigeration and temperature-control fleet is maintained to the standards required for food, pharmaceutical and clinical sites, and we can provide the supporting documentation.
What happens if a unit breaks down during the hire?
Call our 24/7 support line. An engineer will diagnose the fault remotely where possible and, if needed, repair or replace the unit at no extra cost.
