High IP Rating Cabinet Air Conditioner
IP66 and IP67 protection for washdown, dust-heavy, and temporary immersion environments · 1500W-3500W
IP66 Standard
IP67 Optional
NEMA 4X Compliant
This high IP rating cabinet air conditioner is specified for enclosures where dust ingress, high-pressure water jets, or temporary immersion would defeat a standard IP54 or IP55 unit. The standard configuration is rated IP66, providing complete dust-tight construction and protection against high-pressure water jets from any direction. An IP67 configuration is available where temporary immersion is possible, such as flood-prone sites or washdown areas where equipment may be submerged briefly.
The rating is achieved through structural measures rather than sealant application: welded casing seams, dual-lip gaskets on all access panels, sealed cable entries with compression glands, and a condensate path that does not create an open route into the cabinet. The condenser and evaporator air paths remain isolated, so that air drawn through the condenser does not enter the electrical compartment.
Protection Level Comparison
| Rating | Dust protection | Water protection | Typical environment |
|---|---|---|---|
| IP54 | Limited ingress, not harmful | Splashes from any direction | Sheltered outdoor, general plant |
| IP55 | Limited ingress, not harmful | Low-pressure jets | Outdoor, road spray, light washdown |
| IP66 | Dust-tight, no ingress | High-pressure jets, 100 kPa | Heavy washdown, dust-heavy plant |
| IP67 | Dust-tight, no ingress | Temporary immersion, 1 m for 30 min | Flood-prone sites, submerged washdown |
Construction Measures
Welded casing seams Casing panels are welded and ground rather than folded and riveted. No seam is left open to water ingress under jet pressure. Welds are passivated to restore corrosion resistance in the heat-affected zone.
Dual-lip gaskets Access panels carry dual-lip silicone gaskets in a machined channel. The lip geometry maintains contact under pressure variation, and the channel prevents gasket displacement during panel removal and refitting.
Compression cable glands Cable entries use compression glands with EPDM seals, rated to the same protection level as the enclosure. Spare entries are fitted with blanking plugs and seals rather than left open.
Isolated air paths Condenser and evaporator air circuits are separated by a sealed partition. Air passing through the condenser does not enter the electrical compartment, and the evaporator circuit is sealed to the cabinet interior.
Sealed condensate path Condensate is evaporated internally as standard, with no open drain into the cabinet. Where a drain is fitted, it uses a check valve that closes against external water pressure rather than a simple open pipe.
Factory ingress testing Each unit is subjected to jet testing per IEC 60529 before release. For IP67 configurations, units are immersed at 1 m for 30 minutes and inspected for internal moisture. Test records supplied with the unit.
Commercial and Technical Advantages
Dust-tight construction No dust ingress at IP6X, which matters where fine conductive or abrasive dust is present. Filters protect the coil, but the enclosure itself prevents dust reaching terminal blocks and electronics.
High-pressure jet resistance Rated for jets at 100 kPa from any direction per IP66. Suitable for installations cleaned with pressure washers rather than hoses, where IP55 units would allow ingress at gasket edges.
Optional immersion protection IP67 configuration verified by immersion at 1 m for 30 minutes. Specified for flood-prone sites and areas where equipment may be temporarily submerged during cleaning or process spillage.
Hygienic external form Smooth welded exterior without rivet heads or open seams, reducing surfaces where material can accumulate. Relevant for food, beverage, and pharmaceutical installations subject to hygiene inspection.
Ingress test documentation Test records for jet or immersion testing supplied with each unit, supporting specifications that require evidence of protection level rather than declaration alone.
Gasket and seal kits Replacement gasket sets, cable gland seals, and blanking plugs held as service parts for a minimum of 10 years. Seal replacement is a scheduled maintenance item, not a repair.

Deployment Contexts
01 Food and beverage processing Cabinets in production and cleaning zones where high-pressure washdown is routine and hygiene inspection requires smooth, sealed exterior surfaces without crevices.
02 Dust-heavy industrial plants Cabinets in cement, grain, wood processing, and foundry environments where fine abrasive or conductive dust would enter an IP54 or IP55 enclosure and accumulate on terminals.
03 Flood-prone and low-lying sites Outdoor installations in areas subject to surface water accumulation, where the IP67 configuration provides temporary immersion protection during flood events or heavy runoff.
04 Wastewater and chemical plants Installations where equipment is cleaned with hoses and where both moisture ingress and chemical exposure are present, requiring sealed construction in a corrosion-resistant casing.
Selection and Installation Notes
Rating selection Specify IP66 where high-pressure cleaning is routine. Specify IP67 only where temporary immersion is a realistic scenario; the additional sealing measures increase cost and restrict cable gland options. IP66 covers the majority of washdown and dust applications.
Gland and cable planning Cable gland protection level must match the enclosure. Where the site uses armoured cable or conduit entries, confirm the entry method at order stage; standard compression glands suit flexible and unarmoured cable only.
Gasket care during service Gaskets must be inspected each time an access panel is opened. A displaced or contaminated gasket will compromise the rating even if the panel is correctly refitted. Replacement gaskets should be stocked on site for maintenance.
Structural support At 82 kg, the unit requires reinforced mounting. Minimum panel thickness 2.5mm steel, or a load-distributing frame. Where mounted on stainless cabinets, use the supplied stainless hardware rather than substituted fasteners.
Refrigerant handling R454C is classified A2L (mildly flammable). Service must follow local regulations for A2L refrigerants, including ventilation, leak detection, and technician certification. Access to the refrigeration circuit requires breaking the enclosure seal.
Maintenance interval Filter inspection every 2 to 3 months. Condenser coil cleaning quarterly, more frequently where washdown carries material onto the coil. Annual inspection and replacement of gaskets and gland seals as required by the site's protection level obligations.
Procurement FAQ
IP66 covers high-pressure water jets from any direction. IP67 adds temporary immersion protection, verified at 1 m for 30 minutes. The difference matters where water can accumulate around the unit rather than run off it. IP67 units carry additional sealing at the casing seams and cable entries, and have restricted gland options.
No, provided the cutout and mounting are executed per the supplied instructions. The unit's mounting flange carries a gasket that seals against the cabinet panel. The cabinet rating after installation equals the lower of the cabinet's own rating and the unit's rating. Where the cabinet is rated IP66 and the unit IP66, the assembly remains IP66.
Yes. Each unit is jet tested per IEC 60529 before release, and the test record is supplied. IP67 configurations are additionally immersion tested at 1 m for 30 minutes and inspected for internal moisture. Records are per unit, not per batch, and support specifications that require evidence of protection level.
Inspect gaskets each time an access panel is opened. Replace where compression set is visible, where the surface is damaged, or where contamination cannot be cleaned off. In washdown environments, planned replacement every 2 to 3 years is typical. Replacement sets are held as service parts for a minimum of 10 years.
Dimensional drawing, wiring diagram, capacity table, refrigerant data sheet, Modbus register map, mounting template with cutout and gasket details, ingress test record, declaration of conformity under LVD and EMC directives, and NEMA 4X compliance statement.
Standard warranty is 24 months from commissioning or 30 months from shipment. Compressor coverage extends to 60 months. Gaskets and gland seals are consumable items and are not covered by warranty beyond initial defect. Service parts including compressors, EC fans, controllers, and seal kits are held for a minimum of 10 years.
