Rittal’s new Computer Room Air Conditioning (CRAC) system operates by drawing in warm air from the server enclosures at the top of the unit and then cooling it either with water or Dx Refrigerant R407c in a closed heat exchanger. The cooled air is then filtered and blown under positive pressure to the false floor from where it rises into the cold aisle.

The new EC Machine Directive relates to safety issues around items such as control cabinets and machine guards – issues close to the heart of market leaders EMKA who have an extensive range of both locks and hinges to deal with problems of unauthorised access.

FDB Panel Fittings have introduced a new clip fit guide for round locking rod systems to complement the flat rod version recently introduced. This round-rod-guide will suit all those panel builders using the traditional and cheaper round rod systems, while speeding assembly. Such multi-point rod mechanisms are common in larger cabinets from 1200mm to over 2m in height where they optimise clamping of door gaskets.

AMEC Thermasol would like to introduce our new range of Micro Porous Ceramic Heat Sinks (MPCHS). Due to the open irregular structure of the Micro Porous Ceramic the heat sinks provide a greater surface area to contact with the air compared to metal. Due to this structure the heat sinks have excellent heat dissipation and heat convection properties.

One of the biggest enemies for users of outdoor enclosures is the onset of cold weather and with it the possibility of condensation within the structure. In order to eliminate this unwanted natural event, Rittal has introduced heaters for their outdoor cabinet range to keep the chill off delicate electronics housed within them. These, coupled with some enclosures incorporating a double wall design, can ensure the installed equipment works faultle...

Following customer demand, OKW have extended their innovative ‘SOFT-CASE’ handheld enclosures range with the new size ‘XL’ series. Typical applications will include portable instruments, medical devices, mobile data logging and data capture equipment etc.

The comprehensive EMKA 6000 program of toggle latches offers a solution to a wide range of closure needs on boxes, cases, cabinets, access panels, cladding panels and light assemblies. They are also complemented with a series of equipment lifting handles for use on storage cases and as cabinet pull handles, with/without spring return. The 6000 program will be of value to industries as diverse as packaging, transport, aerospace and automotive.

RFI/EMI screening is a discipline that is of interest to both the electronic engineer and the enclosure design engineer. The electronic engineer must take EMC into account when designing PC boards by careful layout, using PCB shielding cans, paying attention to wiring runs, use of filters and ferrites etc. This can eliminate the majority of EMI emissions. However circuit design and layout may not be sufficient to attenuate emissions to the requir...

Rittal has introduced a rapid assembly subrack to save valuable time in production. The horizontal rails are pre-fitted with assembly screws and simply drop into slots in the side plates prior to being tightened up.

Different applications demand different solutions and Rittal has released a new easy-to-read 16 page brochure to help clients choose the right outdoor enclosure for their application. Containing a selection guide covering single and double walled free standing and wall (or pole) mounting enclosures in aluminium and stainless steel, the guide also gives details of “built-in” and “add-on” vandal resistance and noise reduction options for s...
