Two large steam boilers at circlip manufacturer Cirteq have been replaced by an energy-saving system provided by CoSaf Environments, with partial funding from the Carbon Trust
When a tenant left its site in Giusburn, North Yorkshire, Cirteq recognised that it no longer needed to provide process heating using the large on-site steam boilers. As the boilers were costly to run, maintain and insure, Cirteq decided to investigate decentralising its heating requirements for a more cost effective and ecological system.
After contacting the Carbon Trust and establishing that it was eligible for its zero per cent interest business loan for energy saving equipment, Bob Holinski, Citeq's Maintenance Manager, looked for a company able to provide the required design solution.
“We went out to tender, but from the start CoSaf Environment got involved with the project and spent time developing a design solution that would specifically meet our requirements”, said Holinski. “We awarded CoSaf the contract based on cost, expertise and technical know-how."
CoSaf’s design consists of 24-floor standing and suspended gas fired warm air heaters and nine gas-fired radiant heaters, operated with an optimised start. This energy-saving feature predicts what time the heating will have to be turned on to ensure that the required temperature is reached. For example, if the heating is set at 20degC at 8:00am, then the optimised start system will note the external temperature and internal room temperature, and using this information will start to heat the room so that it reaches the desired temperature at the required time. The heaters provide independent heating to the various on-site departments, production buildings and workshops and offer a flexibility of control previously unavailable with the steam boiler system. Payback is expected to be within four years.
In addition, CoSaf installed a dedicated boiler system consisting of a gas-fired boiler plant, pressurisation system, new circulating pumps, flue dilutions and new controls to the four-storey office block. To reduce installation costs, CoSaf has utilised the existing radiators, pipework etc. in the office block to provide the area with its own heating.
