IP69K. Highest protection against dust and jet washing (100 bar, 80°C). Industry guide.

Why is IP69K a strategic choice in LED lighting?

As Lena Lighting S.A., we have been operating in the lighting industry since 1989. With over 36 years of experience in the design and production of industrial lighting, we know perfectly well that in demanding production environments, reliability is paramount.

In food processing, pharmaceutical, and chemical plants, electrical equipment is regularly exposed to extreme conditions: dust, moisture, vibrations, and rigorous high-pressure, high-temperature jet cleaning. In this context, the standard IP protection rating is insufficient.

That's why at Lena Lighting, we offer solutions that meet the highest standards. Choosing luminaires with the IP69K marking guarantees investment security and production continuity – a key, strategic step to minimize downtime.

Deciphering the IP Code: Maximum Protection Defined by Law

Protection ratings, commonly known as IP (Ingress Protection) standards, are international standards that define the level of protection a device provides against solid objects (dust) and water. These standards are defined in IEC 60529.

The IP69K code is the highest rating we can achieve:

First digit (6): Dust-tight. Indicates complete protection against any contact with hazardous parts and full protection against dust ingress. This is absolutely essential in dusty halls or silos.
Second digit (9): Water jet resistance. Indicates protection against flooding with a powerful jet of water under pressure and at elevated temperatures (up to +80°C).
Final letter (K): High-pressure cleaning rigor. The letter "K" is a key extension from the German standard DIN 40050-9. It indicates additional protection against jet/steam cleaning at extremely high pressure.

Rigorous IP69K Testing: Guaranteed Durability

To achieve an IP69K rating, a device must pass rigorous testing protocols that simulate the conditions of industrial machine washdowns. This test provides users with the assurance that the product is completely waterproof and will withstand the rigors of daily cleaning.

IP69K Test Conditions:

Pressure: The water jet is applied at a pressure of 80 to 100 bar (1160 to 1450 PSI).
Temperature: The water is hot, reaching 80°C (176°F), which is crucial for disinfection.
Dynamic Application: The device is placed on a turntable rotating at five revolutions per minute.
Attack Angles: The jet strikes at four different angles (0°, 30°, 60°, and 90°) at close range (10–15 cm).

A product only receives the IP69K certification if it exhibits complete resistance to water ingress in these extreme conditions, which requires the use of durable, waterproof materials and seals.

IP69K in Practice: Addressing Industry Challenges

Devices with this protection class are essential wherever hygiene, reliability, and resistance to aggressive chemicals are a priority.

Food and Pharmaceutical Industry

In the Food & Beverage and Pharmaceutical sectors, IP69K is not an option – it's a requirement. Sterilization procedures such as CIP (Clean in Place) and SIP (Sterilization in Place) require high-pressure and high-temperature cleaning. IP69K equipment helps manufacturers meet stringent sanitary standards (such as HACCP) and minimize the risk of contamination.

Our answer – the Tube IP69K luminaire

For these most challenging environments, Lena Lighting has developed the Tube IP69K luminaire. This cylindrical LED fixture for special tasks is designed to withstand:

Extreme washing: Resistant to water, dust, and high-pressure washing.
Aggressive environments: Made of chemically resistant materials, including extremely resistant borosilicate glass or PMMA.
Corrosion protection: Endcaps turned from acid-resistant steel eliminate the risk of corrosion, which is crucial in the food industry.
Shocks and impacts: The IP69K PC Tube version offers the highest mechanical resistance class IK10.
Temperature variations: The fixture is perfect for use in cold stores and freezers. and in environments with aggressive vapors (e.g. animal breeding – resistance to ammonia and animal gases).

Industrial lighting

Automotive and Rail Industry

Equipment used in vehicles and trains must withstand shock, vibration, and high-pressure washdowns. IP69K is ideal for components that must remain functional even after intense washing (such as in car washes).

FAQ:

🔹 What exactly is the difference between IP69 and IP69K?

➡️ Both levels guarantee complete dust tightness (6) and protection against strong water jets (9). However, IP69K is an additional extension (DIN 40050-9 standard) that precisely confirms resistance to very high pressure (100 bar) and high temperature (80°C) washing, typical of sterilization processes.

🔹What are the key parameters of the IP69K test washing?

➡️ The test involves directing a jet of hot water (up to 80°C) at a pressure of 80-100 bar at a rotating device (5 rpm). The jet impacts from a close distance (10-15 cm) at four angles (0°, 30°, 60°, 90°) for at least 30 seconds at each angle.

🔹 Why is IP69K protection required in the food industry?

➡️ This requirement stems from the need to meet stringent sanitary standards (e.g., HACCP). IP69K equipment enables effective removal of contaminants using high-pressure jets and disinfection using high-temperature water, minimizing the risk of foodborne illness.

🔹 What are the distinguishing features of Lena Lighting IP69K luminaires?

➡️ Our IP69K luminaires, such as the Tuba IP69K, feature chemically resistant materials (e.g., borosilicate glass, PMMA), stainless steel components, and high impact resistance (IK10 in the PC version). We also offer advanced optics (various light distributions, including UGR <19).
