The Future of Refrigerants

Fast Moving Refrigerant Phase Out

Webinar: November 9, 2021 at 2:00 PM EST

How will you be impacted by the impending restrictions on the most commonly used refrigerants?

There is a strong movement within DOE, CEC, CARB, and ASHRAE to prohibit the manufacture of CRAC units charged with refrigerants that have a GWP greater than 750.

As a manufacturer, STULZ is moving quickly to analyze and strategize so we are ready to meet the new requirements, coming as early as January 1, 2025.

Join our Director of Technology Dave Meadows and Product Marketing Specialist Drew Shannon as they discuss the history of the movement to refrigerants with low GWP and what challenges this conversion will present in the data center industry.

Mitigating Harmonics 

In Custom Air Handlers Equipped with EC Fans

Join STULZ, Mirus International, and ebm-papst for Part II of our Deep Dive into Harmonic Distortion in Data Centers. 

To improve energy efficiencies in today’s modern custom air handlers, highly efficient electronically commutated (EC) fans are often incorporated for air movement. This is because these fan systems can improve efficiencies over conventional AC motors equipped with variable frequency drives (VFDs) by 30% or more. An EC fan incorporates a brushless DC permanent magnet motor (BLDC) controlled by an integrated rectifier, inverter, and smart electronics. BLDC motors, with efficiencies greater than 90%, provide a more effective ventilation system so that ‘free cooling’ becomes more easily achievable which contributes to the energy savings potential. Also, air distribution can be improved with multiple fan arrays allowing upstream or downstream components, such as filters or heat exchangers, to receive a more even airflow thereby improving air filtering and heat transfer efficiency.

In striving towards reliable and efficient systems, one significant factor sometimes overlooked is electrical harmonic distortion. One of the few things common with AC/VSD and EC fan systems is that they are both harmonic generating, non-linear loads. Without proper harmonic mitigation, non-linear loads can distort the AC power distribution and possibly expose a mission-critical facility to electrical issues, such as overheating distribution equipment and failure of sensitive equipment connected to the same electrical bus. If harmonics are not effectively mitigated, larger UPS systems and larger power generators may also be required. So investing in proper harmonic solutions compliments the energy savings efforts.

Although both AC and EC systems require harmonic mitigation at times, their solutions can be different. Fortunately, with recent developments in this field, a relatively easy to apply harmonic mitigation solution is available which can ensure that the energy savings of EC fans can be realized without the negative effect of poor power quality

Join us as we talk with Tony Hoevenaars, President and CEO of Mirus International, and Joe Landrette, (Master of Engineering)  Director, VAC & Data Centers and Digital Solutions at ebm-past about understanding the advantage of using EC Fans for Custom Air Handlers and the best practices for mitigating Harmonic distortion in a data center’s electrical distribution system. 

This webinar will be useful to electrical engineers, mechanical engineers, and end-users.




Siemon TechTalk: 
How to Harness the Edge Data Center 

The rise of connected technologies and the changing patterns of our day-to-day lives is driving significant change in the data center landscape. To fully realize the potential of new technologies, including fifth-generation (5G) mobile networks, Telehealth, autonomous vehicles, Online Learning and Business Collaboration we still need to overcome some key technical limitations – primarily latency.

To combat this, Edge data centers have emerged as the best viable option. They mitigate many of the application performance and reliability issues that can be seen today, by reducing the distances between end users, their devices, and the IT resources that support them.

By their very nature, Edge data centers can take many forms and, as with all rapidly emerging approaches, these spaces and where they fit into DC strategies still remain very fluid and continues to evolve.

In this deep-dive session, Siemon and STULZ will scrutinize the Edge DC environment and explore the technologies and key considerations you need to be aware of to successfully implement them. 

In this session we will explore: 

  • The primary drivers for Edge DCs
  • Key challenges for Edge DC environments
  • The latest available technologies and trends that apply to Edge DCs
  • The real-world applications and benefits you can achieve

Capable of managing a wide range of heat loads in remarkably dense packages, liquid cooling can significant reduce data center OPEX when using Direct Liquid Cooling.




IEEE 519-2014
Understanding & Mitigating Harmonic Distortion in Data Centers

STULZ & Mirus International

The modern data center utilizes many non linier electrical loads due to the use of EC motors and VFD’s on the fans and pumps that maintain environmental conditions within the white space. These variable speed pumps and fans allow us to tightly control the data processing environment while providing a more energy efficient system.

One of the potential downsides of these variable speed systems is the harmonic distortion of the power signal. This distortion is caused by the sinusoidal power signal passing through a non-ideal, non-linear device such as a VFD or ECM; additional content is added to the input signal at multiples (harmonics) of the original frequency. Total Harmonic distortion (THD) is the measure of that additional signal content that was not present in the input signal.

This unwanted distortion can increase the current draw in power systems which results in higher temperatures in conductors and transformers. Higher frequency harmonics can result in additional core loss in motors which results in excessive heating of the motor core which can lead to motor failure.

Join us as we talk with Tony Hoevenaars, President and CEO of Mirus International about understanding the requirements and intent of standard IEEE 519-2014 and the best practices for mitigating Harmonic distortion in a data center’s electrical distribution system. Tony will also discuss writing specifications for insuring acceptable levels of harmonic distortion.

This webinar will be useful to electrical engineers, mechanical engineers, and end users.
