Product Description

Flat enclosures pose a retention risk for high-pressure washdown systems and ambient condensation. Sloped top enclosures are fabricated with top-plane inclinations ranging from 15° to 30°, ensuring gravitational runoff and eliminating static pooling. Units are certified under NEMA 4X / IP66 / IP69K and resist ingress from jet spray (DIN 40050-9), foam detergents, and caustic CIP protocols. 

EMI/RFI Shielding

Conductive gasketing with 60 dB attenuation at 1 GHz

Thermal Management

Optional filtered fan kits / heat exchangers / passive venting

Grounding & Bonding Points

Pre-welded grounding studs; copper bonding straps included

Sealing System

Closed-cell polyurethane or silicone gasket; continuous pour-in-place gasket

Fire Resistance Rating

UL 94 V-0 rated components; enclosure meets IEC 60695-2-10 thermal resistance

Environmental Compliance

RoHS, REACH, and WEEE compliant

Load Bearing Capacity

Up to 150 kg static load on door (with reinforced hinges)

Operating Temperature Range

-40°C to +70°C standard; high-temp versions available up to +105°C

UV Stability

UV-resistant coatings and materials per ISO 4892-2; suitable for outdoor use

Salt Spray Resistance

1000+ hours (per ASTM B117 for coated / stainless steel variants)

Seismic Rating

Certified to IBC 2018 / OSHPD pre-approved designs for seismic zones

Mounting Provisions

Wall-mount, floor-mount, or pole-mount; internal DIN rails and back panels

Dimensions

Standard sizes from 400×300×200 mm to 1800×1200×500 mm; custom sizes on request

Weight Capacity

Supports internal load of up to 200 kg with reinforced structure

Lock Type

Quarter-turn, padlockable handle, or 3-point locking with key interlock

Technical Advantages

Top-mounted cable entries are subject to both ingress exposure and EMI leakage. Enclosures are pre-configured or customizable for EMC-rated cable glands (EN 62444), shielding continuity brackets, and grounded backplanes. The sloped interface reduces vertical stress on entry points, improving the service life of cable assemblies and preserving shielding effectiveness across variable cable bend radii. 

Enclosures are fabricated from SS304 or SS316L, with optional passivation (ASTM A967) or electropolishing (Ra < 0.4 μm) for ultra-sanitary conditions. Surface finishes meet cleanability standards in biosafety and food zones, reducing microbial adhesion and facilitating chemical compatibility with chlorinated and peracetic acid sanitizers.

Industry Applications

Food Processing Plants

Prevents fluid retention on enclosure surfaces during high-pressure washdowns in hygienic food-grade zones. 

Pharmaceutical Manufacturing

Minimizes microbial growth risk by enabling complete surface drainage in sterile and validated cleanroom environments.

Dairy Processing Units

Supports CIP/SIP protocols with electropolished SS316L surfaces and slope angles preventing liquid accumulation.

Chemical Handling Systems

Resists corrosion from acidic/alkaline agents; maintains ingress protection under frequent chemical spray exposure.

Meat and Poultry Facilities

Complies with USDA and EHEDG sanitary requirements using crevice-free construction and hygienic slope geometry.

Beverage Bottling Lines

Supports sanitary top-entry cabling with IP69K-rated glands; resists sugar and carbonated residue accumulation.

Structural Load & Mechanical Performance

Designs accommodate distributed loads for top-mounted HMI, conduit trays, or control interface hardware. Units are load tested to maintain <1.5mm deflection under 50kg point loads at the top center axis. Panel doors meet torsional resistance under >20Nm handle torque with zero compression set in door gaskets after 10,000 cycles. 

Each enclosure conforms to EN ISO 14159 and EN 1672-2 for hygienic machine design and is validated for use in Zone 1/2/21/22 hazardous areas when paired with certified components. Units support full documentation packages including FAT, SAT, material certs, and welding maps upon request.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure weld integrity on sloped top enclosures for sanitary environments?

Frigate uses continuous TIG welding with argon purging on all seams to avoid porosity and contamination traps. Welds are ground smooth to a sanitary finish with radiused transitions per EHEDG guidelines. Each enclosure undergoes dye penetrant or visual inspection per ISO 5817.

Can Frigate integrate dual-compartment designs in sloped enclosures for power and control segregation?

Yes, Frigate supports internal segregation using welded partition panels with dedicated gland plates. This allows safe routing of low-voltage I/O and high-voltage circuits within a single enclosure body. It also meets IEC 61439 internal separation guidelines. 

What gasket retention methods does Frigate use for sloped enclosures in CIP environments?

Frigate uses form-fitted silicone or EPDM gaskets in a recessed channel, mechanically secured without adhesives. This prevents chemical degradation during repeated washdowns. Gaskets are IP69K tested and field-replaceable without removing the door. 

How does Frigate handle thermal buildup inside sealed sloped enclosures in humid process zones?

Frigate provides passive venting via IP-rated breather valves or active cooling through gland plate-mounted heat exchangers. Thermal simulations are performed to ensure internal temperatures remain within device operating limits. Options include filtered fans, vortex coolers, or closed-loop systems.

Can Frigate provide material traceability and inspection certificates for sloped enclosures in validated environments?

Yes, Frigate provides full EN 10204 3.1 or 3.2 certification for stainless steel material batches. Surface treatment records, weld maps, and passivation reports are included upon request. This supports qualification in FDA, GMP, and ISO 14644 facilities.
