Profile: TESA (Western) Ltd. specializes in electrical installation of control systems. We are able to supply the complete environmental control package from design through procurement and installation to final commissioning. Our HVAC environmental control systems are modular. Each module is application and target specific, with pre-configured strategies avoiding the need for in-depth programming costs. Each control module is connected to a zone controller which provides optimum start/stop for AHUs, boiler hot-water services, adding even more energy savings, and helping to keep the space at the correct set point. Being able to adjust times and temperatures remotely means the correct temperature set points can be lowered or raised as appropriate, to ease staff by working under more finely controlled conditions.
