In 2018, Chinese data centres produced 99 million tonnes of carbon dioxide (CO2) - generating the equivalent environmental footprint of around 21 million cars. With global data traffic more than doubling every four years, it’s no surprise that the environmental impact of data centres is coming under scrutiny. Here, Simone Bruckner, Managing Director of Cressall Resistors, investigates the efficiency of our data centres.

In recent years, renewable energy options have become much more efficient and feasible. This has led to a large adoption of these applications, an especially poignant point in the face of current environmental issues. However, just like all other power generation methods these applications require resistors. 

In August 2019, Ipswich Hospital plunged into darkness after it was hit during a 15-minute UK-wide power outage. The trust revealed that the disruption caused the unit’s circuit breaker to fail, briefly cutting the electrical supply to outpatients and the x-ray department. Luckily, the hospital’s back-up generators took over and prevented risk to both patients and life-saving medical equipment. 

The range and complexity of electrical equipment has increased dramatically in recent years. An unwanted consequence of this rise is the creation of harmonic currents, which can cause voltage distortion and quality problems. Here Simone Bruckner, Managing Director at Cressall Resistors, has discussed the different harmonic filter resistors that are used to combat these increasing harmonic levels.

The power resistor manufacturer, Cressall, has released an informative infographic explaining the essential questions to ask when designing an enclosure. The guide aims to support design engineers as well as resistor end users across all industries to understand the requirements of their power resistor enclosure. 

Power resistor manufacturer, Cressall has produced an infographic that explains the reasons why consumers are sceptical about electric vehicles, and how the industry should respond to this reluctance. By supporting design engineers to increase their understanding of consumer concerns, Cressall hopes the industry will be able to overcome many of the challenges it faces.

Despite appearing to be a modern phenomenon, the first electric vehicle took to the road in 1832 and in 1899, outselling all other available options, including steam and gasoline powered vehicles. Since 1935, with the invention of the internal combustion engines, gasoline-powered vehicles have become the popular choice. This changed in 2016, which saw a record in the sale of electric vehicles worldwide, with 750,000 cars sold.

They say that one man’s junk can be another man’s gold and, although one may think that the saying only applies to car boot sales, the maxim also illustrates the state of the industrial power resistor market. Here, Martin Nicholls, sales director at Cressall Resistors, offers advice to manufacturers and plant managers who need to replace old or obsolete electrical resistors.

There would seem to be a world of difference between the current generation of advanced electric sports cars and the heavy industries where Leicester based electrical resistor manufacturer, Cressall Resistors traditionally operates. However, the common denominator is a lightweight 25kW water-cooled resistor, as Martin Nicholls of Cressall explains.

One of the most popular works of Renaissance sculpture is Michelangelo’s David, a piece that has become synonymous with human strength and beauty. Despite its seemingly perfect proportions, a basic design flaw of the statue has recently been brought to light. Recurring micro-fractures in the ankles might cause the statue to collapse under its own weight. Author: David Atkins, Projects Director at Cressall Resistors

  Companies in general and data centres, in particular, have become increasingly reliant on the security and continuity of their power supply. Simone Bruckner, Managing Director of Cressall Resistors, explains why regular load bank testing should be a crucial part of any company’s standby strategy.

Manufacturing flexibility has never been as important for industry as it is today. In a world of interconnected devices and smart factories, the ability of a manufacturer to innovate and adapt to its customers’ requirements is vital. For many manufacturers, the road to innovation starts with research and development (R&D). Here Andrew Keith, engineering director of power resistor manufacturer Cressall Resistors, discusses the role ...

South America’s unique geography means it has a wide diversity of wildlife unique to the continent. The llama, anaconder, anteater, agoiti and chinchilla are just some of the 40% of the world’s plant and animal species native to South America. Here, Stewart Wittering, Marketing Director for South America at resistor manufacturer, Cressall Resistors, explains how the South American geography and climate affects the resistor market.

Cressall has purchased an automated fibre laser cutter to ensure its resistors are at the highest level of quality possible. The machine, which has seen an investment of over £0.5 million, will also improve efficiency, with process speed expected to increase fivefold. The equipment, which has been purchased from machine manufacturer Salvagnini, is part of Cressall’s long-term strategy to ensure it remains at the cutting edge of r...

Industrial resistor manufacturer, Cressall, has taken the first steps to launching its products and services in South America. This follows on from the recent opening of the company’s third site in the UK. In March 2017, Cressall visited Colombia to meet potential partners and customers and has now made plans to return early in September and later to visit Chile, Argentina and Peru in order to build partnerships with potential customer...

Following an increase in demand for large scale, high power resistors and load banks, power resistor manufacturer Cressall Resistors has expanded its UK operations. Cressall have taken a lease on a 8,000ft2 unit just five minutes from its UK headquarters in Leicester, allowing the business to work on significantly larger projects.

The East Midlands Chamber Business Awards recognise local businesses that have pioneered new concepts and innovation, excelled in commercial enterprise or set themselves apart with their approach to workforce development. Judges selected Cressall as the overall Business of the Year out of all Leicestershire category winners.

Cressall has demonstrated its design and manufacturing capabilities by producing specialist Neutral Earthing Resistors (NERs) suitable for use in explosive atmospheres. The NERs meet the international IECEx and European ATEX specifications and allow generator manufacturers and end users to protect distributed generation systems. This ensures regulatory compliance and peace of mind for companies operating in explosive environments.

Plant managers across the UK have struggled for years to replace damaged power resistors for one reason or another. Often, the original supplier no longer exists in the UK market, or does not supply resistors any longer, so managers are forced to look for the required components elsewhere. Whether the application is crane control, pumps, fans or compressors, replacement resistors are still needed for legacy systems.
