COOLING FOR ALL EDGE SCENARIOS – FROM SINGLE RACKS TO ENTIRE DATA CENTRES
A
20 and 35kW output class has been added by Rittal to its
portfolio of refrigerant-based IT cooling solutions, meaning it can now offer a cooling solution from 3kW right through to 55kW. The portfolio also includes a
35kW hybrid version that will utilise indirect free cooling where conditions are suitable, making it highly energy-efficient. Compact cooling systems are
also available in high-redundancy configurations. These meet the need of today’s IT infrastructure for high uptime – which is of importance for state-of-the-art edge computing solutions to ensure the uninterrupted flow of data.
The innovative liquid cooling package (LCP) DX/FC Hybrid includes both a refrigerant circuit (DX = direct expansion) and a separate water circuit (CW = cold water). This means that the solution can deliver the required cooling output very efficiently, in line with external temperatures. It’s a particularly cost-effective
solution for locations with low to moderate ambient temperatures as it automatically switches to indirect free cooling when outside temperatures are low, using its external hybrid condenser with integrated free cooler. This use of indirect free cooling is key to helping lower operating costs.
Offering an efficient, space-
saving refrigerant-based solution, the new LCP DX rangefor suite cooling have outputs of 20kW and 35kW and suit small to mid-sized environments. Both devices are inverter-controlled and ideal for cooling IT hardware. They can precisely control the
server inlet air temperature with a maximum deviation of approximately 2 kelvin. The cooling output is continuously adjusted in line with heat loss in the rack, minimising energy consumption for cooling, and cutting IT operating costs.

TT Electronics has introduced its WSHR family of ultra-low-profile resistive heaters to provide compact, dynamic heating and temperature control for applications such as enclosure heating, chemical or food processing, sealing, printing, and medical humidifiers. Less than 2mm thick, and weighing as little
as 6.5 grams, these thick-film on steel heaters save the space consumed by conventional alternatives comprising bulky wirewound or PTC (Positive Temperature Coefficient) components. The family comprises six sizes from 32mm x 28mm up to 152mm x 102mm, with power ratings from 144W at 120V to 1.2kW at 240V. Their planar design ensures uniform temperature distribution across the surface area, enabling a single unit to replace multiple conventional elements. With a wide operating temperature range,
NEW WALL MOUNTING KIT FOR SMALL, FLAT BASED ENCLOSURES
A new suspension element has been released by OKW for its Evotec table-top enclosures, enabling them to be wall mounted. The new wall kit makes this range of enclosures ideal for access control. Other applications include measurement and control engineering, IT, medical, laboratory and environmental technology.
A a The new suspension element will suit any small plastic

enclosure with a flat base. Each kit comprises two parts: an adapter attached to the enclosure and a holder fitted to the wall. The adapter (and enclosure) can then be clipped to the wall holder. The adapter is attached to the base of the enclosure using four
tamperproof Torx stainless steel screws (supplied). Four ø 3.5mm boreholes are required. The holder is fitted to the wall using four
screws. The holes in the holder allow a degree of adjustment to speed up installation. Once clipped into place, the adapter (and enclosure) can be easily unclipped again or secured with two screws (supplied), offering additional protection against removal. Both the adapter (106 x 75mm) and the holder are moulded from UV-stable ASA+PC-FR (UL 94 V-0).

reaching up to 400°C, the heaters provide flexibility with precision. In addition, their low thermal mass ensures a fast time constant to enable fast-acting, accurate dynamic temperature control with minimal energy wastage. A central mounting hole permits easy fixing to a heatsink surface, using a single M2 to M5 bolt depending on heater size. Guidance on tightening torque is provided, to help maximise the contact area for optimum heat transfer. Three choices of electrical terminals give designers the option to connect directly to exposed solder pads or via pre-attached flying leads or push-on connectors. In addition to the standard sizes, TT
Electronics can also provide custom dimensions and shapes to special order. Additional options include non-standard thermal profiles, custom voltage or power ratings, or integrated temperature regulation and measurement. WSHR heaters are RoHS compliant, non- flammable, and feature 2.5kV safety isolation.

ULTRA-SLIM RESISTIVE HEATERS FOR ENCLOSURES
CONNECTED PADLOCK FEATURING U‑BLOX TECHNOLOGY PROTECTS AND TRACKS GOODS IN TRANSIT
u-blox is collaborating with India-based Play Inc. on a connected GPS padlock for industrial applications. The lock, which doubles as a location tracker, features a u‑blox M8 GNSS receiver, MAX-M8Q, and uses the u‑blox CellLocate service to extend positioning to indoor locations. u‑blox Bluetooth low energy with NINA-B112, and 2G, 3G and 4G u-blox cellular communication modules, including some that are ATEX certified, enable communication between users and the lock.

In many industrial settings, locks are an unwelcome bottleneck. They typically require
the physical presence of a person with a key to open them, they need to be checked periodically for signs of tampering, and when they are forced open, owners typically find out too late. Play Inc’s i-Lock combines physical toughness and wireless technology to address these challenges. Offering a variety of access methods, including physical keys and keyless approaches using remote GPRS and SMS passwords as well as Bluetooth low energy or cloud-based communication via mobile device apps, the i-Lock lets plant managers or other customers flexibly grant authorisation to access the goods that are u a

under lock. And in the event that the padlock is forcefully opened, they are immediately alerted via a server or, optionally, SMS.
