Santa Fe Ultra98 Whole Home Dehumidifier - ul4657

Santa Fe Ultra98 Whole Home Dehumidifier - ul4657  

Engineered and assembled in America, this trusted Ultra Series dehumidifier works with HVAC systems. It can be used in crawl spaces, basements, mechanical rooms, and other areas up to 2,300 square feet.

Whole Home Dehumidifying

The Ultra98 Dehumidifier ties directly into your home's ductwork to reduce humidity. It’s rated to remove 98 pints of damaging moisture daily in AHAM conditions (80 degrees F, 60 percent relative humidity) and is designed to service up to 2,300 square feet.

Popular installation options include a basement, crawl space, attic, closet, or mechanical room.

Low-Clearance and Even Quieter Design

An innovative design fits snugly into low-clearance areas. Its unique outer cabinet allows you to convert airflow to discharge vertically or horizontally from the unit in simple steps. These features make installation easier and more flexible in confined spaces.

You can install the unit in areas where other dehumidifiers won't fit due to ducting problems, size constraints, or maintenance difficulties. This unit also features an ultra-quiet design, made possible by a well-insulated cabinet and a super-quiet impeller that helps minimize noise.

Upgrades Available

•  Condensate Pump Available: This dehumidifier is designed to gravity drain collected condensate. However, if you prefer, you can attach an external condensate pump to customize a draining system that can drain condensate upward or across longer distances to a nearby drain. The Santa Fe Condensate Pump Kit Accessory is sold separately.
•  MERV 13 Air Filtration: The system comes standard with a MERV-13 air filter, which captures harmful allergens and particles and keeps the unit running at peak efficiency. This filter needs to be replaced every three months. You can replace your Santa Fe MERV 13 Filter here.

Remote Humidity Controller Options

This dehumidifier must be controlled by a remote dehumidistat controller, which is sold separately. Therma-Stor offers several options. All the control units below are wired directly to the Ultra Series unit using 24-volt pigtail wiring.

•  DEH 3000 Digital Controller: The DEH 3000 is an all-digital controller that allows you to monitor and control humidity, manage fresh air ventilation, and activate air filtration for the unit from your living space. This control also allows you to run the fan continuously instead of only when the unit is in dehumidifying mode.
•  DEH3000R Digital Controller: The DEH 3000R is similar to the DEH 3000 but also features a remote sensor that can be placed up to 100 feet away from the controller. This sensor lets you control and monitor humidity conditions separately, keeping the wall-mounted controller out of sight.

Features 

•  The Highest Efficiency: The Ultra98 is more energy-efficient than previous models. It removes 98 pints of moisture while drawing 5.9 amps and maintaining a 2.95 energy factor. Additionally, this model has received an Energy Star rating for its performance. With these specifications, the 98H is now considered the most energy-efficient 90-100-pint dehumidifier on the market.
•  Small Cabinet Design: At 19.5 in. H, 14.5 in. W, and 32.375 in. D, the 98H is compact enough to match multiple installations. The outer housing also now features rounded edging.
•  Trusted Design: Santa Fe is a trusted name in air quality and dehumidification. This American-made product has a 6-year warranty. 

•  Quiet Operation: Santa Fe product engineers added insulation inside the dehumidifier cabinet and a low-noise impeller to further reduce operating noise.
•  R-454B Refrigerant: The Ultra98 now uses R-454B refrigerant, which is more energy-efficient and environmentally safe than previous formulations.
•  Includes Transformer Protection: The 98H has a 24-volt reset button to prevent damage to your 24-volt transformer if low-voltage wires are crossed.
•  Low-Temperature Operation: The 98H dehumidifier operates in temperatures as low as 49 degrees F and includes an auto defrost function to melt frost build-up in chilly conditions automatically.
•  Long Power Cord: This unit has a 9-foot power cord, which helps make installation options more flexible.
•  Engineered in the USA: Wisconsin-based Therma-Stor engineers and assembles all Santa Fe Ultra Series whole-house ventilating dehumidifiers in the USA using quality components.
