How to choose an IP Rated Industrial Computer

Industrial computers and monitors are usually placed and operated in harsh production environments. It means they must be able to withstand the impact of dust and water and reliably perform in challenging conditions. Some people call these units waterproof and dustproof, but there are special ratings showing the actual level of protection. Let’s take a look at the main standard used in the industrial world - an IP rating.

What is an IP rating and why you need to know

An IP (ingress protection) rating is a standard that measures levels of sealing effectiveness for electrical enclosures against factors such as water, dust and moisture. When selecting an industrial computer, the relevant specifications will usually list the level of IP rating for that particular device. Purchasing a computer compliant with an IP rating ensures reliable operation in demanding conditions where humidity, dust, air-borne particles and water or moisture are a factor. The range of IP ratings extends from IP65 through to IP69K which offers the maximum level of protection. The first digit relates to physical intrusion of solid objects and things such as dust and air-borne particles. Number 1 offers no protection through to number 6 which indicates total protection against dust ingress. The second number refers to the moisture level protection or ingress of liquids. Once again, number 1 offers no protection through to number 8 which protects against long periods of immersion in water. Additionally 69K will protect against close-range high pressure and high temperature spray downs.

What IP ratings do industrial computers usually have

Industrial PCs offer a high level of protection against environmental factors and are much more heavy duty and more suitable for these environments that consumer-grade products. Many units available on the market are fully dustproof (as we already know from the chart above, this means they have the IP6X rating). When it comes to water protection, there are several variations. Let’s take a look at the most commonly available IP rated industrial computers:

• IP65 Computers: Dustproof, protected from splashes and low-pressure jets
• IP66 Computers: Dustproof, protected from strong water jets
• IP67 Computers: Dustproof, protected from temporary immersion in water 1 meter deep for 30 minutes
• IP68 Computers: Dustproof, protected from continuous immersion in water under more severe conditions than IP67
• IP69K Computers: Dustproof, protected from water during high pressure/steam cleaning (not submersible)

All of these PCs feature tough enclosures designed to protect the hardware in challenging environmental conditions. The IP65 computers are the standard for industrial applications, while the IP69K is the maximum level of protection currently available on the market.

What are the benefits of IP69K computers

The IP69K rated PCs feature a rugged enclosure with protection against dust, moisture, high-pressure water and steam and high temperature. Computers compliant with the IP69K rating are designed for applications and environments where equipment must be carefully sanitised. This is vital for industries such as the food processing industry where cleanliness and hygiene are critical. Computers with IP69K rating must be able to withstand severe high pressure and high-temperature wash-down procedures. These units are extremely durable and resistant to harsh environments.

How do industrial computers achieve the IP69K rating

To achieve the IP69K rating, industrial computers are rigorously tested. They are subjected to high-pressure water jets, high temperature and dust to ensure that the enclosure is completely airtight and that the PC and its components are protected from these factors. All necessary testing is carried out by a team of professional engineers under very strict conditions.
