There is an increasing emphasis on the efficiency of electric motors, reducing our energy consumption to help us hit the carbon emission targets around the world.

Considering 45% of all electricity is converted into motion by motors, changes to these could be significant in halting Climate Change. Electric motors are instrumental to our everyday lives, from simple hairdryers to refrigerators to industrial manufacturing machines, with an estimated 300 million electric motor driven systems operating daily. Generating this electricity causes a substantial amount of CO2 emissions, which contributes to Global Warming; so in order to reduce emissions and help the environment, making motors more efficient is one of the best places to start.

The energy efficiency of an electric motor is expressed in the International Energy efficiency classes (IE), IE1 being the lowest class, and IE5 being the highest. IE5 ultra-premium efficiency class, as defined by the IEC (International Electrotechnical Commission), goes well beyond the new minimum standard, IE3, for IE classes for low-voltage motors, established and enforced by the EU Ecodesign Regulation in July 2021.

Benefits of IE5 motors

 

  • Up to 40% lower energy losses compared to IE3 induction motors and 50% lower energy losses compared to an IE2 motor.
  • Lower CO2 emissions
  • Perfect solution for motor retrofits, remarkably easy to retrofit into existing installations, or incorporate into new projects and OEM designs
  • Provides increased reliability & lower maintenance costs
  • Reduced heating/lower running temperatures protect the motor & extend its lifetime.

As well as the obvious positive environmental impact IE5 motors can make compared to their less efficient counterparts (IE1-4), the end user benefits from the reduction in energy usage and expenditure along with the longer life of the motors themselves & less frequent need for maintenance. A more efficient motor can save from several hundred to several tens of thousands of pounds over its lifetime based on its power and usage. This is particularly apparent in motors that run continuously or for long periods, as well as bigger motors generating bigger savings.

IE5 motors at Dutypoint

As technology advances, so must we, and the next logical step we can take, as a company looking to become more sustainable and green, is to make IE5 prominent in our newly developed products, or certainly an option available for our customers who are also working on becoming more sustainable.

This is why we are introducing our latest VR-X system: a variable speed twin, triple and quad high efficiency and space saving pump booster set. Utilising not only the ultra-high efficiency IE5 motors, but also the IES2 compliant drive system.

Our team are continuously working to create further innovations to keep up with industry changes, customer needs and sustainability. Keep an eye out for new systems coming soon.

Category 5 Water Regulations and Backflow Prevention

As a contractor, you’re likely familiar with the intricacies of managing building projects. One such intricacy is ensuring the safety and efficiency of water systems, particularly in new build projects like hotels or residential flats. A key aspect of this is understanding and complying with the Category 5 water regulations, specifically those concerning backflow prevention.

The Threat of Backflow

Backflow is where stagnant or contaminated water is drawn back into the mains water supply. This can happen due to two primary causes: backpressure and back siphonage. Both of these situations force water to flow in the opposite direction to its regular flow path, potentially leading to contamination of the clean water supply.

The risk of backflow is not just theoretical, it is a significant health hazard. It poses a real and immediate risk to health, especially in buildings with high occupancy such as hotels, schools, hospitals, and healthcare facilities. In these spaces, the water system is in constant use, and potentially vulnerable or at-risk users may be using the system. There is also the potential for this backflow to enter the mains water supply, posing a wider public health risk to nearby households and communities.

The Category 5 Water Regulations

The Category 5 water regulations, as outlined in the Water Supply (Water Fittings) Regulations 1999, lay out the requirements for water fittings and plumbing systems concerning backflow prevention. The regulations state that every water system ‘shall contain an adequate device or devices for preventing backflow of fluid from any appliance, fitting or process from occurring’.

These regulations help define the expected level of potential risk to the water supply, which in turn dictates the level of protection needed. The regulations identify five categories of risk, known as the Fluid Categories. Fluid Category 1 requires no specific countermeasures or action and is considered ‘wholesome’ under the Water Industry Act 1991. On the other hand, Fluid Category 5, the highest risk level, presents a very serious health threat. This category calls for a specialist Class 5 backflow prevention device or devices.

The Solution: Dutypoint’s AirBREAK Range

While backflow presents a substantial risk, there are efficient ways to prevent it and ensure an uninterrupted supply of safe, clean water with no risk of harm to other users and to the mains water supply. One solution is available from our AirBREAK range. This WRAS-approved system provides the perfect answer to your Category 5 Fluid needs.

The industry-leading ultra-compact integrated systems boast numerous additional features as standard. These include a 24-month warranty and the support of an experienced technical team, giving you peace of mind. View the full AirBREAK product range today.

Understanding and adhering to Category 5 water regulations is not just about compliance. It’s about ensuring the safety and well-being of the occupants of the buildings you construct. As a responsible contractor, it’s your duty to ensure that the water systems you install are safe, efficient, and compliant with all relevant regulations. Remember, when it comes to backflow prevention, it’s better to be safe than sorry.
