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 the market leader, 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 was chosen for the project because of its technical support, the reliability of its products, the company’s speed of delivery and value for money” said Simon Abela, Project Manager at Engineering for Science and Industry (Malta) Ltd. “I have worked with Sontay on other projects so know how well the company and its products perform. This project was a larger scale than anything we have undertaken with Sontay before but still we were confident they were the right choice and the products work exceptionally well.”

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. Engineering for Science and Industry (Malta) Ltd. [ESI] is an ISO 9001-2000 certified Maltese owned and registered company which is a specialist contractor in the field of industrial and building automation.
