Cooling fans.

The "DiaForce Diagonal" range of cooling fans from EBM-Papst is now available through Inelco Hunter. The revolutionary design incorporates a unique geometry of the impeller and housing: a conical cover plate that rotates with it, whilst the intake opening is smaller than the outlet opening, thus creating a larger pressure ­increase.

In terms of its characteristics, the DiaForce lies between an axial and a centrifugal fan. The DiaForce is quieter thanks to aerodynamic optimisation - the blade tips pass directly into the cover plate. As a result, there is no tip gap and therefore hardly any turbulence in the gap area, where there is a significant pressure gradient. It is this specific design that results in a significant reduction in noise.

The air flows through the fan in both axial and radial directions, enabling a high-pressure increase. It retains an axial design, making it easy to install. Compared to a conventional single-stage axial compact fan, the results are impressive: up to 50% more air performance and up to 6 dB(A) lower sound level. In the context of a typical application, the result is greater performance without compromise. System performance can be enhanced while still satisfying all standards, such as NEBS, OSHA, ANSI and ETSI.

The DiaForce is a complete system consisting of a high-performance DC motor, optimised aerodynamics and intelligent control electronics. Systems that process huge amounts of data are becoming increasingly powerful, and cooling is becoming a challenge in a variety of industries, such as automation, 5G telecommunications, autonomous driving and AI. The DiaForce’s performance is “future-proof” in that it will be able to meet the needs of future applications. Enhanced reliability is another proven benefit - the DiaForce’s power reserves can be used to create redundancy. If, for example the temperature increases, simply increase the speed. This is not possible with conventional single-stage cooling fans because they have to be operated at the power limit even during normal operation.

As an optional extra, the new FanCheck diagnostic tool can be added to the DiaForce. This is integrated into the fan electronics and calculates the realistic service life of the fan based on temperature, speed and preset environmental parameters. This means the fan can stay in operation for longer without any loss of reliability, which saves on costs and protects the environment. The overall dimensions are a very compact 119mm x 119mm x 89mm deep, and mounting is carried out using eight industry-standard mounting holes. It is powered by a 48VDC input and can provide a flow rate of up to 680m3 per hour.

Inelco Hunter works with EBM-Papst to provide a Higher-Level Assembly Service, which enables fan design customisation.

Cooling Fans for electronics.

The DiaForce range of cooling fans from EBM-Papst is now available from Inelco Hunter. Designed specifically for cooling electronic systems, their high performance means that a single DiaForce fan can replace two conventional fans.

Systems that process huge amounts of data are becoming increasingly powerful and cooling is becoming a challenge in a variety of industries, such as telecommunications and automation. To increase cooling capacity, two axial fans are often connected in series, usually with counter-rotating blades. This double-fan layout increases the pressure, but also results in higher noise levels. EBM-Papst’s DiaForce fans can be used instead of twin conventional axial fans.

The secret of the DiaForce lies in the combination of a high-performance motor with a unique impeller and housing geometries. The innovative design of the components for the flow machine minimises the main vortices that cause noise. This ensures a significant noise reduction, and it also increases pressure and efficiency.

One particular advantage in terms of aerodynamics is that the DiaForce offers an air performance curve with no dip. The high maximum cooling capacity is often not required in normal operation because these fans are frequently used in partial-load operation. However, a sufficient power reserve is crucial to ensure that the cooling system delivers adequate cooling, continuing to function sufficiently under conditions outside normal operational range.

The DiaForce 120 has two further sizes available – 40mm and 80mm. The compact DiaForce 80 excels in applications such as server trays and high-performance power supply units with high performance and pleasant noise characteristics. The DiaForce 40 is a still smaller addition to the product range and benefits routers, switches, network technology, industrial automation, control systems and robotics.

As well as offering the fans as standard boxed products, Inelco Hunter offers a High-Level Assembly (HLA) service to help customers with customisation and adaptation. The HLA service involves the integration of various components into larger assemblies, often PCBs within enclosures, and potentially including testing and full customisation. Inelco Hunter’s HLA service can be used to create fully functional, turnkey systems, and their in-depth engineering support ensures rapid implementation, speeding up the customer’s time-to-market.

Fighting condensation in enclosures.

The CS 032 enclosure heater from STEGO with fan delivers high performance and efficiency in a compact design, making it easy to install even in confined spaces. It is available as a Basic version with fixed heating power or as a Plus version with intelligent variable output control.

Electrical systems, particularly those housed in enclosures, often face harsh environmental conditions. This is especially true in power supply systems, renewable energy applications such as wind turbines, infrastructure projects, and mechanical engineering. These enclosures are frequently exposed to significant temperature fluctuations and high humidity levels, leading to the risk of condensation buildup.

Condensation can cause short circuits, which at best result in system shutdowns but, in the worst case, can damage or destroy electrical and electronic components. A proven solution to prevent this is the use of enclosure heaters.

With the CS 032 enclosure heater, STEGO Elektrotechnik introduces two compact models – CS 032 Basic and CS 032 Plus – both featuring integrated fans that combine efficiency and performance with flexible placement and easy installation.

With dimensions of 66 mm (width), 96 mm (height), and 120 mm (depth), these heaters fit even in densely packed enclosures. Designed for operating temperatures from -45°C to 70°C (-49°F to 158°F) and relative humidity levels of up to 90%, they offer a wide range of application possibilities. The units are available for 220-240 V AC and 110-120 V AC power supplies, ensuring compatibility across various electrical systems.

CS 032 Basic: Compact with Three Heating Power Options.
The Basic version is available in three models with fixed heating capacities of 600, 800, and 1,000 W. It can be easily integrated into an existing control system.

This enclosure heater offers flexible mounting options, allowing the warm airflow to be directed either sideways or vertically. Like the Plus version, it features an integrated automatic temperature monitor, which activates overheating protection in the unlikely event of a fan failure.

CS 032 Plus: More Flexibility with Enhanced Efficiency.
The Plus version features variable heating output ranging from 600 to 1,200 W and intelligent control for optimized heating operation. The desired temperature can be continuously adjusted using a control dial.

In cases of significant temperature drops (e.g., in extremely cold environments), the quick heating function activates, operating at maximum heating power and fan speed. When only minor deviations from the target temperature occur, the heater switches to an energy-saving mode with reduced output, adjusting over time. This optimizes energy consumption, reducing power usage by up to 23%.

The CS 032 Plus also offers greater flexibility in installation — it can even be mounted upside down. Another key benefit is the simplified inventory and preparation process, as only one unit is needed for various performance requirements.

Easy Installation and Safe Operation.
Space inside an enclosure is often limited, making installation challenging. To simplify this, the CS 032 comes with both a clip-mounting kit for 35 mm DIN rails and a screw-mounting option.

The push-in terminal allows for quick and tool-free electrical connection, reducing installation time by up to two-thirds while ensuring a stable and secure connection — even during transport of pre-configured enclosures.

When working inside an enclosure, safety is a top priority, particularly protection against accidental contact. The touch-safe plastic housing of the CS 032 enclosure heater ensures that it remains at a safe temperature, preventing any risk of injury during maintenance.

Compact axial fan.

A compact axial fan that measures just 40mm by 28mm has been released by EAO Ltd.  It delivers ample airflow and static pressure necessary to cool the latest space-constrained 1U racks typically used today to accommodate high performance servers, switching power supplies and comms. equipment.

Developed by cooling specialist Sanyo Denki the new San Ace 40 12VDC axial fan delivers an airflow rate of up to 37.1 cubic feet per minute (CFM) and a static pressure of 2.300 Pa and easily outperforms the counter-rotating fans designers usually choose to cool modern 1U rack applications.

According to Robert Davies, Marketing Manager with EAO Ltd, the new San Ace 40 axial fan is built with a newly developed impeller and frame construction that delivers higher static pressure, together with proprietary motor, magnet and circuitry innovations that need much less power to operate: “Space inside a 1U rack is becoming increasingly tight at engineers try to squeeze more equipment into the same space,” Davies said. “This results in a high-pressure, high- impedance system that needs a lot of cooling airflow”. The usual cooling approach for 1U rack applications is a counter-rotating fan, but these units are space hungry and can be noisy: “The new San Ace 40 axial fan is half the volume of a counter-rotating alternative, saving 28mm of depth”, continued Davies. “Further, with this fan designers only need to accommodate half the number of fan connectors and half the number of speed sensor inputs”.

The San Ace 40 (model number 9HVA0412P3J001) provides a pulse sensor as standard but sensor-less and lock sensor variants are available. An expected fan life of 53,000 hours at 40oC ensures maintenance-free long-term operation.
