Outdoor Dual Projector Harsh-Weather Protection Enclosure For Christie DWU-HS Series Laser Projectors

A heavy-duty, dual-chassis environmental enclosure system specifically engineered to protect two Christie DWU-HS series 1DLP® laser projectors (typically DWU850-HS, DWU1050-HS, or DWU2020-HS models) from all extreme weather conditions. This solution enables permanent outdoor installation for high-brightness projection in the most demanding environments, from coastal salt spray to desert dust storms.

Protection Specifications

• Housed Projectors: 2 × Christie DWU-HS Series (8,500 to 20,000+ lumens, WUXGA/4K, HS Series Laser)

• Environmental Rating: IP68 / NEMA 4X (Dust-tight & protected against continuous immersion up to 1m)

• Climate Resilience:

  • Temperature: -40°C to +55°C (-40°F to 131°F) operational

  • Humidity: 0-100% RH, condensing

  • Solar Load: Designed for direct sunlight exposure with integrated sunshields

• Corrosion Protection: MIL-STD-810G compliant for salt fog, fungal, and chemical resistance

• Impact Resistance: IK10 rated (20 joule impact protection) on optical windows

Hardened Design Features for Maximum Weather Protection

1. Military-Grade Sealing & Construction

• Dual Independent Sealed Chambers: Each projector resides in its own IP68-rated compartment with separate environmental control—prevents cross-contamination if one chamber is breached

• Monocoque Aluminum Construction: CNC-machined from solid 6061-T6 aluminum billets with continuous welds, eliminating seams where water could penetrate

• Redundant Sealing System:

  • Primary: Compression-molded silicone gaskets

  • Secondary: O-ring channels at all openings

  • Tertiary: Internal bead of marine-grade silicone sealant

• Pressure Equalization: Automatic vent valves with hydrophobic membranes that allow air pressure balancing while blocking moisture

2. Extreme Climate Management System

• Dual-Redundant HVAC Units: Two independent 3000 BTU heat pump systems per chamber with automatic failover

• Arctic-Cold Start Package:

  • Projector compartment pre-heaters (500W ceramic)

  • Optical window radiant heaters

  • Battery-backed thermal maintenance for off-power periods

• Tropical/Humidity Package:

  • Dual-stage dehumidification (refrigerant + desiccant wheel)

  • Positive pressure nitrogen purge option (for zero-humidity environments)

• Desert/Dust Storm Mode: Electrostatic precipitators + HEPA H14 filtration (99.995% @ 0.3µm)

3. All-Weather Optical Integrity

• Ballistic-Grade Optical Assembly:

  • Outer layer: 19mm laminated tempered glass with hydrophobic coating

  • Middle layer: 6mm aerogel insulation

  • Inner layer: 8mm anti-reflective, anti-fog coated optical glass

• Automated Window Maintenance:

  • Ultrasonic vibration system to shed snow/ice accumulation

  • Integrated wiper system with heated washer fluid reservoir

  • Rain-sensing auto-cleaning activation

• Alignment Preservation: Invar steel (low thermal expansion) mounting rails maintain optical alignment through extreme temperature swings

Why This System Protects Christie DWU-HS Specifically

• Laser Engine Preservation: Maintains optimal 25-30°C operating temperature for laser phosphor wheels and diode arrays

• Sealed Optical Path Protection: Prevents contamination of Christie’s sealed light engine from dust/sand ingress

• Color Consistency: Stable thermal environment maintains Christie HS Series’ superior color accuracy

• Filter-Free Design Compatible: Christie’s filter-free design works perfectly with the enclosure’s HEPA filtration

Maintenance Features for Harsh Environments

• No-Open Maintenance: 90% of service (filter cleaning, fluid refills) performed via external service ports

• Corrosion-Proof Fasteners: All external hardware is A4 (316) stainless or titanium

• Self-Diagnostics: Built-in particle counters, pressure sensors, and thermal cameras monitor internal conditions

• Rapid Re-seal System: Quarter-turn latches with visual seal integrity indicators
