As a production manager, considerations such as the protection of your machinery and equipment are key aspects and concerns. In challenging environments with moisture and dust, the risks of breakage are higher and so is the need for a higher IP-rated machine. Read on to discover what you need to be aware of.

In this second post, we’ll be looking more at the implications of IP ratings on coding and marking equipment and the impact they have on the decision makers, building on our first post which covered the basics: what are IP ratings and what do they mean?

The production environment for a typical beverage application (be that alcoholic or soft drinks) is likely to be one where equipment will need to be washed down as part of the sanitisation process, so it will often be wet. What is the best IP rating to choose for such an environment?

Clearly the coder needs to be able to be washed down, usually with a hose or pressure washer, so a higher second digit IP rating is desirable, meaning IPX5 would often be specified. This IP rating is fine to protect the coder against wash-downs, but long-term implications of this wet environment for the coder also need to be considered.

Airborne contamination such as moisture, sugar and syrup, will start to build up over time inside the coder as a result of the air blown through it to cool the electronics. This often causes faults and/or poor reliability; therefore, a higher moisture resistance IP rating generally proves more beneficial to a coder in an aggressive wet environment.

Protecting environment from ingression is key to long-term reliability and Overall Equipment Effectiveness (OEE) – sealing the electronics is one way of achieving a higher IP moisture rating. Keeping cool then becomes key to the reliability of the coder and an appropriate cooling system will need to be deployed.

Now imagine the opposite scenario, where a coder is in a dusty beverage environment, such as a tea or coffee factory. Waterproofing is likely to be less important than taking dustproofing into consideration. The IP rating charts show a rating of 5 or 6 to be the best fit, but the judgement call needs to be between dust protected and dust tight. It is most likely that in all but the dustiest application, the dust protected option will give the desired level of protection making it imperative to ensure the system’s air filter is kept clean at all times, to protect the printer.
