Sontay provides control
The new Mater Dei Hospital, one of the largest building automation projects to take place in Malta in recent times, features an extensive range of building control peripherals and field device products from Sontay. Mater Dei Hospital is a new, state of the art, acute teaching hospital located in Tal Qroqq, Malta, providing a full range of general services as well as specialist care. Controls specialist Engineering for Science and Industry (Malta) Ltd (ESI) has integrated over 1,500 Sontay products into this vast project.
They provide the eyes and ears for the Siemens building management system and ensure that building services systems and equipment operate at optimum efficiency and performance. These include air differential pressure switches, temperature sensors, liquid pressure sensors and switches, liquid level switches and sensors and air quality sensors.
ESI has selected Sontay TT temperature sensors for a wide range of different applications at the hospital. These include sensors which measure air temperature in the air-conditioning ductwork running through the hospital, immersion sensors detailing the water temperature at various points in the building’s pipework system and space sensors which provide air temperature readings in operating theatres, patient wards, treatment rooms and other spaces.
The project also features nearly 650 of Sontay’s PA-604 Air Differential Pressure Switches. These are used to provide an important indicator of fan status and ‘filter dirty’ conditions within the building’s air-conditioning and ventilation plant.
Sontay products and control solutions are designed to help improve building management system performance, reduce energy and maintenance costs and increase occupant comfort levels.
At Mater Dei, ESI provided the engineering, design, supply, installation, software development, testing and commissioning of the BMS based on a Siemens S7 PLC system with a Siemens WinCC SCADA system to control and monitor the new hospital.
The BMS controls and monitors all HVAC plant, corridor lighting, lifts and escalators, medical gases, generator sets, pumps, boilers, calorifiers, heat exchangers and other equipment. It also controls a number of life safety systems such as fire smoke dampers, smoke fans and provides a critical link between all HVAC plant and the Fire alarm.
