C.Caswell Engineering Services Limited – known simply in the industry as Caswell – specialise in providing ventilation and air conditioning solutions for all types of catering outlets.
Experience-focused restaurant chains, one-off fine dining establishments or high footfall ‘fast-food’ outlets, whatever the style we have worked with the best for many decades.
We offer our Clients a turnkey service and are with them throughout to smoothly guide and deliver the project from conception to completion. Working closely with many stakeholders, from the restaurateur to top MEP Consultants, Designers, Architects and other construction professionals, means we ensure that their specific needs are not only met but exceeded.
Our experience in delivering peerless solutions, a high quality of service and outstanding levels of customer care provides the reassurance and peace of mind needed throughout the installation period.
This has resulted in Caswell completing the installation of ventilation and air-conditioning systems on over 1,430 newbuild restaurants (and counting) plus innumerable refurbishment projects around the country.
Our vision is to create the perfect restaurant environment.
Our strength is in our ability to provide solutions which meet the comfort, welfare and safety needs of both staff and customers alike.
We believe we can offer everything a Client would wish, up to a full-service package which covers every stage of a Restaurant Ventilation project.
We have many decades of experience and expertise to undertake the high responsibility of project management and report directly to our Clients to provide them with sound and trustworthy advice.
Caswell have extensive expertise in sourcing and installing industry-leading Air-Conditioning systems as part of our overall Restaurant Ventilation Services package. We are a long-established Mitsubishi Electric Business Solutions Partner.
Options include Ducted, Cassettes and Fan Coil types which are proven to be the best solutions for restaurants as they can be mounted within the ceiling void and ducted to air supply grilles.
Heat pump systems are an alternative solution as these provide both heating and cooling. These are arguably becoming the preferred choice given their eco-credentials.
All of these systems are installed complete with DX and condensate pipework to external condensers as and when required.
Wherever possible, we recommend the use of a dedicated Heat Recovery system to capture up to 95% of the significant thermal energy which Commercial Kitchens naturally create.
This is just a small part of our commitment to promoting and utilizing environmentally-sustainable heating and cooling solutions. More here
