AIR CONDITIONING An air conditioned environment is increasingly expected in retail, commercial and industrial premises. Whilst there will always be a demand for custom built air conditioning the standard off the shelf product market continues to grow. Established 25 years ago, Qualitair was one of the first British manufacturers of standard air conditioning products and it was acquired by Eaton-Williams Group in 1993. This has created an air conditioning business that can provide standard product solutions to a wide range of specialised applications and projects. The Qualitair portfolio covers chilled water and DX (direct expansion) refrigeration product ranges including ceiling cassettes, high and low wall split systems, free standing or in-wall packaged units, concealed fan-coil units and roof-top models. Qualitair can cater for simple cooling only requirements up to full close control unit applications for computer or control room areas. For food preparation areas it offers a unique low temperature ceiling cassette that can operate down to 10ºC, meeting many of the forthcoming EU directives and legislation. Cellar cooling, storage of fresh fruit, vegetables and florist stocks are protected with Qualitair refrigeration split systems. Qualitair products are supported by an in-house technical team and all products come with a 3-year warranty. Qualitair was one of the first manufacturers to have products tested, duties verified and performances certified by Eurovent.
