Products Enclosures Compact chillers give efficient cooling
Pfannenberg UK has extended its ecool enclosure thermal management portfolio with the introduction of the CC Compact range of air-water chillers. There are six models rated at 1,100 to 6,500W.
Applications range from machine tools, plastic processing, the food, drink and pharmaceutical industries, as well as printing units, packaging lines, welding systems and IT server cabinets. The chiller, which is typically used in conjunction with a cabinet mounted air- water heat exchanger, reduces the load on the building air conditioning system by extracting the heat in a closed loop system to outside the building, thus reducing costs. Closed loop air-water cooling is also an effective solution where conventional thermal management with cooling units or filter fans is not possible due to dust or dirt pollution. The chillers can be interconnected in a ring configuration to give redundancy for critical applications
and the optimised airflow through the units provide improved temperature sta- bility and allows operation in higher ambient temperatures up to 45°C. The chillers include removable side panels and a hinged front door enabling easy access to the components. IP54 sealing allows the units to be installed in harsh ambient conditions.
The units carry UL, cUL, GOST and CE
Approvals. They also have ETL 1995 cer- tification, making them well suited for machine manufacturers who work interna- tionally. For more information, visit pfan-

Pentair’s Schroff type R europacPRO ruggedised sub- rack, has successfully passed all environmental tests for use in particularly harsh operating environments. For security and defence applications, shock and vibration resistance has been confirmed to the levels
Software making things easier
The RiLine60 from Rittal, a fully shield- ed flexible busbar system with a wide range of busbar adaptors, provides a solution for power distribution within control cabinets.
Rittal’s RPE design software has been developed for the creation of a parts list for a distribution system. The RPE soft- ware has been designed to integrate RiLine60 into standard Rittal enclosures - TS 8, SE 8, AE, CM and KS. Rittal’s RPE software can produce a detailed CAD design showing the bus- bar system inside enclosures with the full range of accessories available. Rittal

required for MIL-STD-810G and MIL-STD-901. Tested according to IEC 61587-1 DL2 conditions, the shock and vibration resistance of the Schroff type R europacPRO ruggedised subrack is proven up to 10g and under IEC 61587-1 DL 3, it is proven up to 25g. Equally important in these fields is enhanced EMC protection. Here the type R europacPRO ruggedised subrack passed a test conforming to VG 95373 part 15 and interference immunity was certi- fied in the frequency range from 30MHz to 2GHz. The Schroff type R europacPRO subrack is sup- plied in one of two versions - either configurable from single components or as a complete kit with pre-mounted components such as threaded inserts, EMC gaskets, etc. All test results and videos are available online at:

Enter 212 New fire protection option adds safety
Hawke International has added a fire pro- tection option to its enclosure range. The robust S-Series stainless steel enclosure, for cable termination in demanding envi- ronments, is now available with a K-Mass fire protective coating. The new SK Series enclosures provide safety with up to 30 minutes fire protection at 1,093°C. The enclosures are designed to protect critical systems during the early stages of fire as well as giving reliable every day environmental protection for electrical equipment in Zone 1, 2, 21 and 22 haz- ardous environments. Applications will be in offshore and onshore oil and gas installations, chemical and process plants. In addition to fire protection, the enclosures are suited to any environment where there are potentially explosive gasses and dusts. The K-Mass insulation is a two-part polyamide cured epoxy that is moulded onto the stainless steel case in a quality assured factory process. Insulation is only
activated if there is a fire. The outer layer expands and chars to minimise heat trans- mission, keeping the internal temperature within the enclosure below 60°C. The K-Mass coating is resistant to sun, rain and salt spray, physically aggressive environments and chemicals includ- ing hydrocarbons, bases and acids. The enclosures are IP66 rated for ingress protection and DTS01 rated for deluge protection. The enclosures are suitable for con-
trol and instrumentation applications and are fitted with Hawke cable glands installed through a 3mm gland plate. Base plate entry is the standard, but side entry is available if required. Cable glands are shielded by a sec- ondary K-Mass protected box, provid- ing fire protection to the glands. The box is easily removed for periodic access and inspection of the glands. The insulation has minimal effect on the thermal perfor- mance of the enclosure at normal tempera-
