Generators
Temporary Power
Power for the equipment your site depends on
Temporary power for hired boilers, chillers, heaters and other equipment when the mains supply is unavailable or cannot support the required load.
Boilers, chillers, heaters and air handling units (AHUs) all need a suitable power source. On many sites this is not available yet or cannot take the extra load. When the available electrical supply cannot support our hired equipment, we can help specify a generator package to suit the installation.
Typical uses include construction sites before permanent supply is connected, existing sites where the current supply cannot support additional equipment, and events requiring temporary heating and cooling. We also provide generator hire alongside chillers for temporary ice rinks, where additional power is needed.
Cross Rental Services' team considers what needs powering, operating hours, connection requirements and access. Generator hire includes the necessary supporting equipment for the agreed installation.
How Cross Rental Services Supports Generator Hire
- Temporary heating and cooling plant power
- Ice rink cooling and event climate control
- Silenced generators ranging from 20kVA to 1,260kVA
- Supporting equipment for the agreed installation.
Complete Hire Support
Power, equipment and fuel planned together
A generator needs to suit the load and the site, not simply a headline capacity. We can bundle the generator with temporary HVAC plant, supporting equipment and optional fuel storage, monitoring and replenishment, reducing the number of separate rentals your team needs to manage.
- Electrical load and start-up demand assessed
- Single or three-phase equipment considered
- Site access, connections and installation requirements reviewed
- Noise and emission restrictions on site considered when specifying equipment
- Generator capacity and fuel management planned around operating hours.

Why CRS
Benefits of hiring chillers from us
Six reasons customers choose Cross Rental Services for temporary cooling, from the size of the fleet to the people who install it.
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.
