Santa Fe Ultra V125 Ventilating Dehumidifier - ul17436

Santa Fe Ultra V125 Ventilating Dehumidifier - ul17436

The Santa Fe Ultra V125 Ventilating Dehumidifier delivers whole-house humidity and fresh air management for demanding residential and light commercial spaces up to 3,000 square feet. Designed for both new construction and retrofits, it pairs high-capacity moisture removal with controlled ventilation to help you maintain a consistent, healthy indoor environment.

This horizontal Santa Fe Ultra Dehumidifier design integrates with existing ductwork or operates as a dedicated crawl space, attic, or basement dehumidifier, giving you installation flexibility without compromising performance.

Features 

• High Capacity: Removes up to 125 pints daily from areas up to 3,000 square feet under AHAM conditions (80 degrees F and 60 percent RH), protecting your home from moisture-related damage, mold, and mildew.
• Built-In Ventilation: An integrated 8-inch duct introduces fresh outdoor air into your space, helping you satisfy ASHRAE 62.2 fresh air requirements with one appliance.
• MERV-13 Filtration: The high-efficiencys fine particles and allergens, delivering cleaner supply air and reducing HVAC maintenance.
• Energy-Efficient Operation: Produces 5.9 pints per kWh, lowering operating costs compared with portable or oversized equipment.
• Insulated Cabinet: The sound-dampening design of the R2 insulated steel cabinet limits vibration and noise for quieter performance near occupied zones.
• Eco-Friendly Refrigerant: This model uses the eco-friendly R-454B refrigerant, which is more energy efficient and has a lower global warming potential than older refrigerant formulas.
• Wide Operating Range: Reliable dehumidification in cool crawl spaces, unconditioned living spaces, and hot attics in a 34 to 105 degrees F range.
• Digital Controls: Set humidity locally from the integrated digital controls or pair it with the optional DEH 3000 wall controller for remote monitoring and alarms.
• Low-Profile Layout: Multiple duct collar options (8-inch and 10-inch) and compact dimensions simplify placement in tight mechanical rooms or between floor joists.

What our Experts Think

• High-Performance Ventilating System (125 Pints/Day)
  The Ultra V125 combines powerful dehumidification with controlled fresh-air ventilation, making it ideal for whole-home, new construction, or sealed building environments up to ~3,000 sq. ft.
• Built-In Fresh Air Intake (Key Differentiator)
  Includes an 8-inch ventilation duct that brings in outdoor air, helping meet ASHRAE 62.2 ventilation standards while managing humidity in a single integrated system.
• Whole-House Moisture Protection
  Removes up to 125 pints per day, delivering strong protection against mold, mildew, condensation, and structural moisture damage in tightly sealed homes.
• Energy-Efficient, Continuous Operation
  Engineered for high efficiency (~5.9 pints/kWh), supporting 24/7 operation with lower long-term energy costs compared to portable dehumidifiers.
• Advanced Air Quality Support (MERV-13 Filtration)
  Integrated MERV-13 filter captures fine dust, allergens, and airborne particles, improving overall indoor air quality alongside humidity control.
• HVAC Integration Ready
  Designed for ducted installation or standalone operation, allowing flexible integration into existing HVAC systems for balanced whole-house performance.
• Smart Control Compatibility
  Supports onboard digital controls or optional advanced controllers for precise humidity and ventilation management across multiple zones.
  
  

Q&A

Maintenance Tips

• Replace MERV-13 filter every 3–6 months – Maintains strong airflow and protects internal coils from dust buildup.
• Keep 1 ft (12") clearance around unit – Ensures proper intake and discharge airflow for efficient whole-house performance.
• Clean or inspect air intake & duct connections – Prevents restriction in the 8" ventilation duct and maintains fresh air performance.
• Check drain line regularly – Ensure continuous slope and no clogs to avoid water backup or leaks.
• Verify humidistat / control settings – Keep RH setpoint correctly calibrated for stable humidity control and energy efficiency.
• Inspect coils annually – Remove dust buildup to maintain heat exchange efficiency and prevent icing.
• Maintain proper operating temperature (34°F–105°F) – Avoid freezing conditions that can reduce performance or trigger defrost cycles.
• Ensure secure ducting & backdraft dampers – Prevent air leakage and maintain balanced ventilation flow.
• Schedule yearly professional service – Recommended for inspection of refrigeration system, electrical components, and airflow calibration.
