The trust has an existing rooftop chiller that has failed and needed a quick solution to supply air conditioning to their Outpatients and Ear, Nose & Throat departments.
Watkins Hire Chiller Hire specialist Chris Easterlow carried out a detailed survey, he looked at the situation on site including transport access, available space for positioning equipment on the roof of the building, site power conditions, routes for chilled water pipe work, before leaving site he carefully measured the exact distances required for power cables, steelworks (to build a new base for positioning the equipment) and flexible pipe works. With his specialist knowledge Watkins Hire developed an engineered solution. The KwikCHILL 80 chiller was selected to match the cooling demand required for the separate areas and because the super quiet 54 db(A) Sound pressure level (10m) to ensure no disturbance to local residents as the building is on a main road in a housing estate.
The Facilities Manager said
“Watkins Hire responded immediately to our enquiry, their specialist manager was on site within 2 hours, and offered a fast efficient cooling solution. The way in which Watkins Hire were going to run the project gave us complete satisfaction that we did not have to bring in any sub-contractors. The whole project from delivery, contract crane lift, on site works, electrical installation and commissioning of the system were all handled by the Watkins Hire project manager. They could also install at the weekend to prevent any disturbance to our day to day running of the hospital. Along with the fact that the chiller supplied was the most energy efficient from the alternatives the whole project sold itself”
The rental chiller was delivered on the Saturday by Watkins Hire own transport and the chiller hire unit was lifted onto the building using a certified crane contractor, the 80kW Trane Aquastream Chiller has a dual refrigeration circuit and 2 compressors and as such provides built-in emergency cover. A fabricator was also on site to weld temporary flanged adaptors into the customers system to allow Watkins Hire flexible chilled water pipes to be connected to the building existing air distribution system. A Watkins Hire qualified electrician was also on site to complete the installation of the power to allow the system to operate. The installation was started at 7.00a.m on Saturday morning and the system was fully operational by 4.30p.m in the afternoon.
The facilities manager continues
“We have worked with other companies in the past for temporary cooling equipment, the speed in which Watkins had reacted and helped us far exceeded our expectations, we are very happy to recommend Watkins Hire because of the standard of the equipment supplied and the level of service supplied by Watkins Chiller Hire. They handled the whole project with a level of competence and professionalism, we have now put in placed an agreement with Watkins Hire for all temporary cooling, heating and boiler equipment.”
