Advisor saves Creganna Medical
27% in their annual energy spend



BACKGROUND:

Creganna was first established in 1980, initially serving a range of industries and providing a variety of outsourced engineering solutions.

Since 2000 the company has experienced significant growth within the medical device sector through a mixture of new products, technology and service developments, along with geographic expansion and acquisitions.

Specialising in minimally invasive delivery & access devices, Creganna Medical provides the full spectrum of services to design, develop and deliver finished medical devices to market. Today Creganna Medical operates from a network spanning over 4 continents, and is ranked among the Top 3 providers of minimally invasive medical device outsourcing solutions in the world. The private limited company is headquartered in Ireland.


Challanges of energy spend:

The main goal of the project was to consistently conserve energy spend and reduce energy costs in non-production hours within the PM3 Cleanroom 2. For example the Cleanroom plant became operational in Q4 of 2014. It is approximately 4,000ft² and was on average consuming 48kwh over the weekend with no occupancy. The Cleanroom is a controlled environment and therefore pressure, temperature and humidity had to remain within specifications (there can be no effect on particulate levels within the room). All testing was carried out by an external vendor and were as follows: BMS controls were upgraded to regulate all changes within the Cleanroom. Also a heat pump was switched off for the summer months as it would consume 21kwh running at full load.

Benefits:

Prior to testing, the energy base line was 40kwh during non-production hours, however by the end of the project, the base line was cut in half to 20kwh.

ResourceKraft’s metering solutions have greatly increased management control and understanding of energy usage within the company.

These changes have facilitated the identification of different project as well. “Since 2013 when the metering was installed we have completed a different project in the company”, explains Declan Coleman, Facilities Technician at Creganna Medical. “The project resulted in a savings of 135,983kwh as well as reducing energy cost of €13,599. Since completing this project we have 2 more cleanrooms that are in the process of setback mode testing. When the setback mode is in place we will consume 528kwh over a 24 hour period at the weekend instead of 2,880kwh”, concludes Declan.
