Refurbishment and modernisation of heat management at the National Cancer Institute in Bratislava

 

CAMASE successfully participated in a public tender announced by the National Cancer Institute (NCI) in Bratislava in 2013 to refurbish and modernise the NCI’s heat management system. A refurbishment of the main steam boiler plant and a modernisation of two hot water boiler plants were the primary components of this project. The tender was intended to achieve efficiencies, in particular by decreasing the consumption of the primary fuel used to produce heat, steam and hot water.

The installation of new, high efficiency boilers and gas burners with smooth output modulation, as well as the deployment of energy management services for operating the heat sources, delivered a substantial reduction in the NCI’s natural gas consumption. The delivery and installation of modern equipment and a control system played a major role in these efforts. In practical terms, the project involved the acquisition of a highly efficient energy management system, limiting operating costs, complying with legal regulations and decreasing environmental emissions.

The control system in the low-pressure gas hot water boiler plant was modernised within the scope of the project as well; this boiler plant provides heat and hot water to three accommodation facilities for NCI employees.

The control system for the heat sources supplying heat to the Radiation Therapy building, located directly within the building itself, was also modernised and is now used to independently supply heat and hot water.

CAMASE provided the following scope of services to the NCI after successfully completing the refurbishment and modernisation of its heating equipment:

  • Comprehensive administration of heat sources
  • Maintenance, repairs and operation of the equipment
  • Emergency services and technical equipment service
  • Specialised inspections and testing of technological equipment, controls and instrumentation

Energy management

  • increasing the reliability of the equipment during its operation under specialised supervision
  • capital appreciation
  • guaranteed long-term efficiency

We successfully brought 2015 to a close

The consumption of natural gas for heating, hot water and steam generation for the NCI in Bratislava in 2015 can be compared the reference year of 2012 – before the refurbishment and modernisation of the primary steam boiler plant and two hot water boiler plants.
