Aqua Hire Gets Top Marks On Uni Project

The Client –

University In The South Of England


The Challenge –

Existing Air Con Chiller Being Replaced


The Solution –

Medium Term Planned Maintenance Solution

The Aqua Hire team stepped in with a complete planned maintenance solution for a university who needed to keep their air conditioning system running whilst their existing air conditioning chiller was being replaced. Without a temporary replacement the campus faced being without air conditioning across the classrooms and laboratories of their medical facility.

When choosing their preferred supplier, our client was focussed on finding a hire company that could manage the complete project from start to finish. Aqua Hire’s proven ability to take a project from initial design stage to final installation made us the obvious choice.

From a cooling capacity point of view, the project required a 350kW chiller. However, because students would be studying in classrooms near to where the temporary chiller would be sited, noise attenuation was key. Our design engineers therefore chose a chiller unit with a low turn down of fans and compressors – by 10% – and then incorporated fencing with sound curtaining into the design to reduce noise further.

When it came to installation our engineers took a power supply from the campus’ main distribution board to enable the power supply to the existing chiller to be used on the temporary unit. They also modified the existing pipework to connect the rental chiller. Both the existing building system water – and the temporary system water – had glycol added to give frost protection over the winter months.

The full solution included:

  • Bespoke design
  • 350kW chiller unit – to low noise specification
  • Electrical and mechanical works
  • Project management from start to finish
  • Ancillaries – including additional hoses and cabling
  • HIAB delivery

“This project is a great example of how we believe we really set ourselves apart from others within the rental market” explains Ed Gale, Sales Manager for Aqua Hire. “Our service offering isn’t just about dropping rental kit to site, we pride ourselves on offering a complete solution and the best level of customer service. We work with our customers to establish exactly what they need, whether that’s a rapid emergency response or a long- term lease hire approach.”

Aqua Delivers On Defence Project

The Client –

Defence Client, South Of England


The Challenge –

Cooling Tower Replacement, Critical Application


The Solution –

Highly Technical Chiller Solution With Built-in Redundancy

Often with hire installations time is of the essence and customers are keen to get equipment delivered to site as soon as possible. However, for a client working within the defence sector, the highly sensitive and critical nature of their application meant that technical expertise and attention to detail were paramount, with a complex design stage lasting 10 months.

Our client had a legacy cooling tower on site which they needed to replace, with the existing tower providing cooling to submarine frequency convertors. Aqua were tasked with providing a temporary solution which would keep the facility up and running whilst the cooling tower was taken out of service during the planned maintenance works.

The design scope was worked on with the client over a 10-month period, with every aspect checked and double checked to ensure the system was completely resilient and every possible fail safe was in place. It was crucial that the temporary system had built in redundancy and the final design achieved 740kW of cooling, through 2 x 390kW chillers and a 1000kW plate heat exchanger.

To give an additional level of assurance, remote monitoring was built into the chiller hire units and pumps, so that if a system alarm should be triggered for any reason, nominated personnel would receive a notification by text and email. A visual alarm was also incorporated, with beacon lights built in so that should a fault arise it would be easily visible to warehouse personnel.

The full solution included:

  • 390kW chiller x 2
  • 1000kW plate heat exchanger
  • Primary side pumps
  • Secondary pumps – with run and standby
  • Remote monitoring & built-in alarm

The maintenance works were scheduled over a 20-week period. This was staged across 2 areas on the site, with each area commissioned in turn over 10 weeks. The temporary system was installed in one area initially and then decommissioned, relocated and re-installed in the second area.

The site also had strict environmental procedures to adhere to. For example, when filling any buffer vessel using site mains water, we provided an “air gap” every time, so no contact was made between the hose and vessel which reduces overall contamination risk. In addition, IBC containers were supplied for when the glycol water was drained down, ensuring it was safely transported around site. At the end of the contract all treated water was removed from site in its entirety.

“For me this project showcases our technical ability and how the hire sector isn’t always about short term contracts and rapid turnarounds” explains Ed Gale, Aqua Hire. “For planned maintenance clients and complex applications such as this, it’s often more about the finer detail and documentation and working in partnership to ensure things run seamlessly throughout.”

Hire System Gets Product Trial On Track

The Client –

Hampshire Based Cosmetics Manufacturer


The Challenge –

Product Development Trial


The Solution –

Bespoke Hire Package

For the research and development laboratory at a leading cosmetic company, a bespoke Chiller Hire solution proved to be the answer when they were faced with challenges during product development.

In this scenario, system flexibility was key. The lab was working under the constraints of a very specific time scale when cooling the product. It was critical to ensure it wasn’t cooled too quickly or too slowly, otherwise product would be compromised and have quality and cost implications further down the line.

Being a cosmetic manufacturer, our client had an existing chilled water supply on site. However, for the trial they needed their cooling water to be completely independent so that there was no risk to day to day production in their main plant.

To ensure the laboratory could vary pressure, temperature and flow rates, Aqua supplied the following:

  • Variable speed pump – this enabled both pressure and flow rates to be changed as and when required
  • Heat exchanger with a 3-way value – this gave full control over the temperature
  • 30kW chiller
  • System design and installation

With a flexible hire agreement in place, our client only rents the equipment for as long as they need it. Once optimum flow rates and conditions have been established for mainstream production of the product the above equipment can be easily off hired with just one phone call to our hire desk.

Aqua Provide Emergency Response To Police Station

The Client –

Police Centre In Hampshire

 


The Challenge –

Failing Boiler System Affecting Heating

 


The Solution –

Containerised Boiler Room, Short-Term Hire

A facilities maintenance client got in touch with Aqua Heating Hire when a failing Boiler Heating system at one of their sites was affecting the comfort Heating supply.

The building, a fully operational police station, had two long standing boiler units in-situ which were responsible for providing Heating to the entire building, via a radiator system. One unit had already failed and the second was showing real signs of struggling during the colder winter months.

An Aqua Heating Hire engineer went to site, carried out a site survey and a 300kW containerised gas boiler room was immediately ordered. Once the unit was delivered to site, our Gas Safe accredited installation engineers were able to run a temporary gas tract from the building’s gas main to the Boiler Plant Room. This meant the heating system was back on line within 72 hours from when the initial call came into our Hire desk!

The Boiler was hired on a flexible short-term agreement, giving the client time to replace the failed equipment, safe in the knowledge that the heating supply to the Police Station would be unaffected. Aqua’s range of Containerised Boilers are a cost effective and efficient hire option because they provide a fully packaged solution. Everything plant room related is contained within the one place and they can also be sited away from the main building, overcoming space and real estate issues for clients.

Aqua’s Hire team understand the specific requirements that their FM clients have, for example the importance of rapid response, service backup and flexible Hire options.

Long Term Hire Provides Worry Free Solution

The Client –

Spot Welding Factory Based In Kent


The Challenge –

Legacy Equipment Struggling With Demand


The Solution –

Long-Term Chiller Hire

For a service and maintenance customer, long term Hire proved to be the perfect solution as their legacy equipment began to struggle keeping up with production demand.

The client, based in Kent had two, non-Aqua supplied chiller units, which were integral to cooling their spot welding process. Aqua had been previously appointed as their designated service and maintenance supplier. When the compressor on one unit failed, our client was faced with a costly repair, disruption to their process and the reality of knowing their second unit could also fail at any time.

As an interim measure, the engineer arranged for the Aqua hire team to supply a replacement 50kW chiller to get production back underway and to give the client time to consider their longer-term options.

Impressed with the unit supplied, the client took the decision to replace both their legacy units with Chiller Hire units on an annual contract basis. This saved on the cost of repair as well as giving a host of other benefits, including:

  • Minimal capital expenditure – hire gives you all the advantages and efficiencies of up to date technology but with no real investment. Hire costs are treated as operational spend, rather than capital expenditure, keeping the kit off the balance sheet and improving tax efficiency
  • Fixed, regular operating costs – so budgeting is easy each month and there’s no surprises. Costs are inclusive of service and support which negates the need for a separate contingency for repairs and maintenance
  • Flexibility – if production requirements change or your business plan changes, equipment can be easily upscaled. Equally, in the unlikely case that something goes wrong with the hire unit it’s quickly and simply swapped with another from our fleet

So, as well as their production being back on course, the client now operates with total peace of mind that they’re now protected from that type of scenario reoccurring.
