Rittal – Hygienic Design



2 Rittal Hygienic Design

The Rittal Hygienic Design for food safety is based on:● Machinery Directive

(98/37/EC)Food Machinery sec-tion, Appendix 1, point2.1 (to be replaced by2006/42/EC)

● DIN EN 1672-2:2005Food machinery –General designprinciples – Part 2:Hygiene requirements

● DIN EN ISO 14 159Machine safety –Hygiene requirementspertaining to thedesign of machinery

● Document 13 EHEDG-Guideline to thehygienic design ofapparatus for openprocesses, prepared incollaboration with 3-Aand NSF International

Rittal Hygienic Design pursues four main aims:● Higher productivity through greater system availability● Reducing the amount of cleaning required (faster cleaning,

reduced energy requirements, reduced use of chemicals)● Superior product quality and greater durability by reducing the

contamination risk, which in turn helps to avoid production losses● Improved protection for both consumers and employees

Cleaning and disinfectionHygiene checks and the moni-toring of cleaning processeshave revealed that the use ofhigh pressures harbours therisk of organic contaminants(fats or proteins) enteringniches and being more widelydistributed. For this reason,

pressures are being signi-cantly reduced.

Decide for yourself what isimportant:● High pressure-resistant

design A labyrinth in front of the sealor multiple screw-fastening

of the lid or door to the enclo-sure, to enable the use ofhigh pressure hosing of upto 120 bar, whether static ormanual.As well as hampering servic-ing, multiple screw-fasteningalso harbours additional

hygiene risks resulting fromincorrectly tightened screwsor damaged seals.

● Hygienic design The new Hygienic Design HDavoids the hollows and deadspaces found in labyrinths forhigh pressure applications.

RITTAL OFFERS THE “KEY” TOOPTIMUM HYGIENE FOR ALLSECTORS!

The completely new lock insert is synonymous with the consistency

of Rittal Hygienic Design. Featuring a high protection category, it

has nowhere for micro-organisms to hide, making cleaning easy.

The same is true of the entire new product line, in every respect.Rittal Hygienic Design reduces the risk of contamination and

signicantly increases productivity.

BECOME HEALTHIER, BETTERAND MORE PRODUCTIVE –WITH RITTAL HYGIENIC DESIGN

When it comes to the increasing demands of food safety, stainless

steel enclosures and enclosures in hygienic design are “two different

animals”.

Rittal Hygienic Design offers mechanical engineers and plant opera-tors in the food sector decisive new building-blocks for the hygiene

demands of the future. This innovative sub-range is based on our

world-renowned expertise in enclosure manufacturing and enclosure

climate control.



Hygienic DesignCompact enclosures


Enclosure roof tilted forwardsthrough 30˚● Covers the horizontal gap

between the enclosure anddoor

● Overhang edge preventsliquids from running onto theseal

● Sufciently large gap betweenthe overhang edge and thedoor, easy to clean from thefront

● Heat loss dissipation is

encouraged by the largersurface area. This mayeliminate the need for climatecontrol components.

Door ● Chamfered edge fold

prevents liquids fromaccumulating

● With hinges tted inside theseal, i.e. in the enclosure.

Special silicone seal ● Gap-free seal against the

enclosure● High resistance to acids,

alkaline solutions, detergentsand disinfectants.

Mounting plateWith the existing standarddimensions of AE compactenclosuresThe design is a matter ofcustomer preference:● Sheet steel, spray nished● Sheet steel, spray-nished,

resistant to high-pressurecleaning

● Stainless steel● Stainless steel, resistant to

high-pressure cleaning● or the new Hygienic

Design HDOnce project planned, themounting plate remains thesame.

Benets in detail:Enclosure with smooth, gap-freesurface.No additional gaps through:Gland plate with cable entry.● Cable glands are tted

directly in the required sizes

Sealed holes for the wall or oormounting.● Holes for two, three or four

wall spacer brackets may be

drilled where needed● The enclosure may behygienically welded to themachine or plant

HD cable gland, stainless steelSuitable for use in the following areas● Manufacturing and packaging of foodstuffs etc.● Clean room technology (e.g. pharmaceuticals)● Biotechnology● Chemical industryBenets: ● Smooth, solid exterior surfaces effectively

prevent the depositing of harmful micro-organisms. All threads are beneath the cap nut.

● Much easier, therefore cheaper, cleaningcompared with conventional stainless steelcable glands.

● Reliable strain relief, thanks to duplicate cableattachment.

● Resistant to high-pressure cleaning (protectioncategory IP 69K).

Support arm system CP-L,stainless steelIn conjunction with the HD compact enclosureand cable entry from below, this offers the idealsolution for the human/machine interface.The larger diameter provides space to insertseveral cables and/or larger connectors, andsupports greater weights and offers increasedstability when assembling the operating unit.The support section, bent from a single piece,offers ideal hygienic conditions. Furthermore,there are no attachment components or sharp-edged steps on support arm components such aswall/oor mounting, enclosure couplingor enclosure attachment. All seals are external toensure optimum hygiene requirements. For wallmounting from the outside, we recommend anadditional seal and hex screws.

Due to the possibility of condensation forming inthe support arm system as a result of temperatureuctuations, when cleaning and disinfecting theplant we recommend that the support arm shouldbe attached to the bottom of the enclosurewherever possible.

Theintegral sealing membrane largely prevents suchpressure differences and hence condensation;additionally, they prevent the ingress of moisturefrom the outside.

Liquid cooling concepts


DCP mounting platePower electronic components can be cooled particularly

effectively using the liquid cooled plate. Heat losses are

cleverly dissipated from the enclosure or housing without

compromising the high enclosure protection category in any

way. Furthermore, liquid cooling is both quiet and a thousand

times more efcient than heat dissipation via air.

The Rittal DCP Cold Plate has received type-tested certication from the TÜV inspectionauthority and is approved for pressures up to10 bar.
