The future is with ultra-high efficiency motors. The Domel motor is the most efficient industrial motor ever produced in serial production1, and therefore ideal for use in data centres.
Motor concept for data centres
Motors come with rotor grounding as standard, and we also offer hybrid (ceramic) bearings as an option.
UL/CSA approved, and CE marked.
Highest efficiency for cooling your data centre
Data centre equipment and servers put off a lot of heat, which means significant spending on cooling and air conditioning. The electricity used by IT devices in the data centre is ultimately converted into heat, which must be removed by cooling equipment that also runs on electricity. On average, servers and cooling systems account for the greatest shares of direct electricity use in data centres, at 43% each, followed by storage drives (11%) and network devices (3%) (Shehabi et al., 2016). Operators face increasing pressure to reduce their environmental impact and deliver competitively priced services to support users. Domel followed the trend in delivering to energy savings, and in 2009 started with the serial production of PMS motors specifically designed for HVAC applications. These motors comply with the regulations and directives for motor efficiency requirements, guarantee huge energy savings, and as a result improved return on investment.
Domel’s EC motors exceed the IE5 efficiency class (according to IEC 60034-30-2).
Our motors reduce operating costs by working at a very high level of efficiency within a wide speed and power range, significantly reducing total operational costs.
Advanced technology and state-of-the-art equipment ensure the highest quality and long lifetime of the product with maintenance-free operation.
EC Systems, a business unit operating independently since 1998 under the able leadership of Mr Lojze Demšar, stands out as one of the most successful units within the Domel company. EC Systems manages its own sales, development, technology and quality control, while central services like planning, procurement and logistics support them.
Team and Work Environment
Currently, around 70 dedicated employees are involved in EC Systems’ programmes, primarily hailing from the Selška Dolina region and the vicinity of Škofja Loka. They operate cohesively as a team, conducting regular monthly programme meetings and weekly troubleshooting sessions. The department maintains a seamless flow of information, fostering a productive working atmosphere.
At the end of each year, the sales, development and production leaders present the results of the past year and outline plans for the upcoming year to all employees, including production workers. This inclusive approach ensures that everyone understands their roles and contributions. Additionally, the team comes together twice a year for a summer picnic and a pre-New Year celebration. In the winter, some colleagues even gather for Tuesday evening football matches, strengthening their bonds outside of work.
EC Systems predominantly specializes in fume extraction systems , followed by industrial vacuum cleaners, fuel cells, washing disinfectors and printing machines. Over the last three years, they have actively engaged in hydrogen technology, offering comprehensive solutions for air supply and pumps for hydrogen recirculation. This commitment aligns with their efforts to contribute to a greener future by reducing carbon footprints and preserving the environment for future generations.
In 2023, the largest markets for EC Systems are:
EC blowers find applications wherever:
a) long lifetime is essential, with their minimum expected operational time of 20,000 hours;
b) where the absence of brush dust is required, unlike traditional vacuum units;
c) precision control is required.
The EC blower&pump product range covers various voltages (low voltage, high voltage, DC and AC), with blowers ranging up to 2,500W in power. A global EC blower has been introduced operating at 100–240V, along with CAN communication capabilities for seamless integration with other systems.
EC Systems actively fosters innovation, generating numerous proposals, some of which have received awards. Notably, two Gold Award recipients hail from this business unit.
Since July 2020, a new expansion has been in place to accommodate increased production needs.
EC Systems establish a flexible medium-volume production approach, enabling the assembly of various products within a single shift. Since 2014, they’ve operated on two shifts. This year is expected to see a production increase of approximately 10%. They produce over 300 different blower concepts, necessitating an exceptionally flexible production process.
Sales and Development
Regular market trend monitoring guides EC Systems’ sales strategy, with a focus on identifying market needs before embarking on new product development. They currently serve over 250 different customers. All aspects of product development, including electronics and motor development, are carried out in-house. The development encompasses mechanical, electrical and software aspects.
