Fontana Touchless — Aviation-Ready Electrical & Mechanical Profile (AEC Technical Article)

Fontana Touchless — Aviation-Ready Electrical & Mechanical Profile

Engineer-grade summary for architects, aircraft OEMs, MRO teams, and specification writers. Emphasis on durability, sustainability, and system integration for commercial and institutional environments, including compact aircraft lavatories.

Images above are hosted on FontanaShowers.com (Aviation/Lavatory program) and suitable for AEC documentation use.

1) Power Architecture & EMC Discipline

Electrical Envelope

Input range: 12–28 VDC (typical aircraft buses); optional AC service modules for 110–240 VAC ground carts.
Power hygiene: Sub-watt idle draw with short activation bursts to limit thermal rise and DC bus noise.
Protection: Reverse-polarity, inrush/current limiting, and line filtering for conducted emissions control.
Converters: Wide-range buck/boost regulation to maintain stable sensing/valve timing during transients.

EMC Considerations

Grounded housings, filtered solenoid drivers, and shielded harnessing to support avionics coexistence.
Design aims to align with RTCA DO-160 EMC sections for radiated/conducted emissions and susceptibility in cabin installations.
Harness routing and bonding points detailed in installation notes for repeatable, low-noise integration.

2) Vibration, Shock & Ingress Protection

Mechanical Robustness

Targeted to DO-160 vibration categories representative of lavatory/monument mounting locations.
Potted electronics with conformal-coated PCBs; strain-relieved connectors for repeated service access.
Ingress protection objectives of IP65–IP67 for resistance to humidity, cleaning agents, and splash.

Materials & Finishes

316 stainless or plated brass bodies; PVD finishes for corrosion and detergent resistance.
Elastomer selection validated for temperature/humidity cycling and disinfectant exposure.
Hardware locking features (thread-lock, captive fasteners) to sustain turbulence/door-slam shock.

3) Compact Envelope & LRU Serviceability

Space & Weight

Short spout projection and minimized controller volume ease retrofits in tight monuments.
Low-mass assemblies reduce panel loads and mitigate fatigue on composite cabinetry.

Maintenance Model

Modular electronics/valving for line-replaceable-unit (LRU) swaps without structural rework.
Quick-connect water and power interfaces to reduce mean-time-to-service.

4) Water Performance & Sustainability Alignment

For commercial and institutional specifications (airports, terminals, and public buildings), water performance targets should align with recognized frameworks. While aircraft flow targets are typically lower for tank mass optimization, the following standards inform engineering baselines for ground environments and can guide airport-side lavatory specs:

Framework	Relevance to Touchless Faucets	Integration Notes
ADA Accessibility	Clear knee/toe space, reach ranges, and operability with no tight grasping or twisting.	Hands-free activation supports operability; verify spout reach & basin geometry in plan.
WaterSense	High-efficiency flow rates (e.g., ≤0.5 gpm in many commercial contexts) with performance criteria.	Select appropriate aerators/flow controls for terminal restrooms and lounges.
CALGreen	California green building code water-efficiency caps for public lavatories.	Coordinate flow restrictors and mixing temperatures with project plumbing schedules.
ASME A112.18.1 / CSA B125.1	Plumbing supply fitting performance and safety requirements.	Confirm model-specific certifications in submittals for non-aircraft facilities.

5) System Integration — Architecture & Documentation

Typical Submittal Package

Dimensional drawings (deck/wall cutouts, spout projection, mounting fasteners).
Wiring diagram (12–28 VDC integration, grounding, isolation, fuse spec).
Hydraulic schematic (check valves, service shut-offs, aerator/flow control options).
Maintenance plan (filters, seals, solenoid cycles, diagnostic indicators).
Environmental test matrix mapping to DO-160 sections for aviation applications.

Recommended Design Checks

Verify spout clearances to basin and mirror to minimize false triggers in glossy environments.
Confirm harness routing and clamp spacing to control vibration nodes.
Specify disinfectant compatibility per airline/airport cleaning SOPs.
