Rapid Energy was approached by a new client facing a critical need to reinstate cooling services for an office block at a renowned London University. The existing chillers had long been non-operational, posing a pressing challenge as summer approached and internal temperatures rose, impacting the comfort of students and lecturers. The client sought a swift resolution within a tight timeframe of less than a week.

Solution Implementation

To swiftly address the cooling issue, Rapid Energy dispatched a technical representative to the site the following day. The goal was to assess the situation, outline a scope of works, and devise a temporary solution. Collaborating with the client, enabling works were agreed upon to facilitate the connection of the temporary chillers.

Installation Process

Upon surveying the site, a proposal was made to utilise three 150kW chillers that could connect into the existing system, delivering chilled water to the primary circuit. However, due to space constraints on the roof, a ground-floor location was chosen and approved by the client. Three 160kW chillers were connected to a shared manifold to bolster the chiller hire solution’s reliability. The flow and return route were planned to run internally within the building.

Addressing the power requirements was crucial. Rapid Energy communicated the need for three-phase 125 amp supplies, prompting the client’s onsite electricians to prepare the necessary power supplies from the main control board in advance.

The equipment was swiftly loaded onto the HIAB the next morning. By 10 am, both the engineers and equipment were on-site. They proceeded to isolate the permanent system using existing 4” isolation valves. Following the connection of hoses and electrical supplies, Rapid Energy engineers commenced the commissioning process, channeling chiller water back into the cooling system. Remarkably, this was completed on the same day, swiftly reducing internal temperatures from 26 degrees to a comfortable 20 degrees.

Installation and location


The client was highly satisfied with the swift resolution. They extended the hire duration from 12 to 20 weeks and expressed interest in engaging Rapid Energy again for a similar solution next year. This successful collaboration ensured a comfortable environment for students and lecturers while showcasing Rapid Energy’s reliability and expertise.
