Our services range from and not limited to domestic, commercial and industrial installations. We have a vast range of expertise in the HVAC field and as recently as 2008, we completed a energy saving application by combining chilled water chillers and a thermal ice storage Cristopia tank. The system saves energy by building ice in the storage vessel over night and then using the ice during the day, minimising the need to run the chillers until the ice is melted, thereby saving cost on electricity during peak load. Other energy saving applications used by EIS include the applications used at the Virgin Actives and Planet Fitness gyms where rejected heat from the condensers that cool the building, is then used to heat up the hot water to the showers. EIS possesses the necessary management, technical skills and resources to carry out contracts in the Gauteng region to a maximum contract value of approximately R25.0 million. All site installation activities are carried out in-house including the electrical installation. We undertake contract only installations according to the design by Consulting Engineers or can provide a design and contract service utilizing tried and tested heat load calculation programmes. We produce CAD working drawings utilising the latest AutoCAD software to ensure speed, accuracy and quality of work. We also undertake the service and maintenance of air conditioning systems and number several Clients with whom we have had a long association. The section under the Service and Maintenance Contracts indicate the nature of systems that we maintain which include most types of commercial and specialised buildings. We are presently engaged in various works for Netcare, M-Net and the upgrading of the air conditioning at many of the Virgin Active Group of health clubs. We are also providing the air conditioning and hot water services to the new Planet Fitness Gym at Village Walk and a major air conditioning upgrade at 124 Main Street, Johannesburg.
