As access to the school site was limited, TK Air Conditioning designed a heating system that could be built on two skids, both of which could be imported whole. The heating boilers were installed on the first skid and a plant room built onto the second. To fulfil the requirement for regular monitoring, specialist sensors were incorporated into the heat pump boilers that transmit real-time data that is processed and can be fed directly back to the heating engineers and the client.
Before leaving TKAC’s manufacturing premises the Ecodan CAHV units were fully tested.
In this instance, off-site manufacturing reduced the installation time by 75%, making it quicker, safer and cheaper for the client. The cost of constructing a roof plinth was also eliminated by locating the skids directly onto anti-vibration pads, ensuring they stayed comfortably within the maximum load dictated by the structural engineers.
“The process of getting equipment onto a roof can take time and involve engineers in working at height, often around other construction workers,” said Mitch Swirles, Managing Director of TK Air Conditioning . “This increases the potential for accidents and the risk of damage to the equipment itself. To avoid this we package the heat pumps onto specially constructed skids, which also incorporate an electricity supply and deliver them on a Just-In-Time basis which negates the need for other specialists to work around the plant.”
Once in place the new ‘plug and play’ solution just needed to be connected to the water and electricity supplies and were immediately able to provide heat and hot water to the whole school building.

Turn Key Air Conditioning have a long history of working in partnership with some of the most notable names in the UK. We design, install and maintain air conditioning & heat recovery systems for high street chains, schools & colleges, local retailers, business parks, medical centres and office developments.
Not surprisingly our experience and expertise makes us the perfect choice for the design and installation of air conditioning & heating systems in the hotel sector. Over recent years TKAC have been appointed time after time by some of the UK’s best known hotel groups to create energy efficient heating & air conditioning systems that meet the highest expectations of their guests.
In any new build or refurbishment project Turn Key Air Conditioning is an essential wheel in a larger machine. While air conditioning & heating systems are designed to meet the long term requirements of the client – minimising energy costs while providing clean, fresh air at controllable temperatures – the installation phase has to be handled sensitively. Turn Key AC take great care to cause minimum disruption to the day to day operations of our clients and wherever possible manufacturing is carried out off-site. We also coordinate all on-site installation work with other contractors.
But it is not just on the construction site where TKAC work in partnership. Turn Key AC have developed lasting and effective partnerships with all the major names in HVAC manufacturing, including technology giants Mitsubishi Electrics. For the Crowne Plaza Hotel, TKAC opted for a Mitsubishi Electric Multi Heat Recovery System.
The Crowne Plaza Hotel in Gerrards Cross, Buckinghamshire is a 147 bedroom hotel and conference centre. It was recently bought by the Cairn Hotel Group and has undergone a total refurbishment. TKAC has an ongoing relationship with the Cairn Group – as consultants and as air conditioning maintenance engineers – and worked with them on the Crowne Plaza project from day one to design a system that meets all the requirements of guest comfort, energy and legislation.
One of the challenges in the Crowne Plaza Hotel was that each room is distinctive but to TKAC every challenge offers an opportunity. In this case the opportunity was to use Mitsubishi City Multi System where the unique two pipe heat recovery system provides much more flexibility in design and installation. More than this, the combination of inspired design and innovative product meant that we were able to design out the need for leak detection.
Current legislation – EN378 in particular – restricts the use of refrigerants to minimise potential hazards to people, property and the environment. TKAC worked closely with Mitsubishi Electric Value Added Reseller (VAR) PACAIR to design the system to minimise the amount of refrigerant in each bedroom to comply with EN378.
Working with PACAIR also saw Turn Key install Mitsubishi’s Melcotel ™ hotel control system which links every individual room to the Ving cards to stop the system from operating when the room is unoccupied. Melcotel gives a significant energy cost saving to the hotel with no loss of comfort for customers.
One of the many benefits of the TKAC design of the air conditioning & heat recovery system for the Crowne Plaza Hotel was that installation could be carried out in 5 phases to fit in with the requirements of the whole refurbishment project.
Turn Key AC fitted the infrastructure to the ground floor before installing ducted fancoil units in the hotel bedrooms. Mitsubishi City Multi ceiling cassettes were installed in all public areas and Lossnay ventilation and heat recovery units were used to maximise the flow of fresh air into the building.
These requirements were met by TK Air Conditioning’s innovative offsite manufacturing process. The air conditioning cassettes were configured off site on 2 large skids. Here all of the electrical and piping requirements were installed, meaning that the system simply required connection to the hotel’s systems when on site.
Roof space was at an absolute premium for this project, and the 2 skids were required to locate onto the hotel roof with only a 3mm tolerance for pipework connection. The installation also had to synchronise with kitchen operating times, as the kitchen extraction system had to be removed during installation.
Instead of TK Air Conditioning’s contracting team being onsite for 3 weeks, with all of the attendant disruption and inconvenience to hotel staff and guests, the project was completed in 6 hours on a quiet Sunday morning.

This building in Glasgow was originally built in the 19th century as a power station and more recently converted to a call centre for a large insurance company. The offices in the building were open plan and for the conversion into a state of the art 96 bedroom hotel, a 5th floor has been added.
Castle Building Services were appointed as the M&E contractors, who in turn appointed TK Air Conditioning as the specialist air conditioning contractor.
The building has an imposing listed facade and internally, TK Air Conditioning had to design the air conditioning system emanating from the hotel’s central lobby configuration.
For ease of cleaning and maintenance retractable air conditioning fan coils were introduced in each room.
Mitsubishi heat recovery VRF air conditioning units were installed. This system design allowed the client to benefit from the advanced capital allowance scheme. The system is designed to have very low operating cost and to reduce the client’s carbon footprint.
