Santa Fe Ultra98

Description

Recognized as the first genuine in-wall dehumidifier, the UltraMD33 helps create a healthier, more comfortable indoor environment. Designed for spaces up to 1,200 square feet, it effectively removes up to 33 pints of moisture per day—ideal for individual rooms or multi-family residences.

Built-In Dehumidification

Say goodbye to bulky, noisy portable dehumidifiers. The Santa Fe UltraMD33—previously known as the Ultra-Aire MD33—installs directly between wall studs, saving space while offering powerful moisture control. It’s a smart solution for apartments, hotels, and other compact living areas.

How It Works

Once installed, simply set your preferred humidity level on the electronic humidistat. The unit takes it from there, keeping humidity in check with minimal effort on your part. Air enters through lower vents on the front and sides, then exits through the top and upper side vents for effective circulation. To prevent tampering, the on/off button and humidity set point are tucked behind the diffuser—an ideal setup for spaces like hotels, senior communities, and anywhere controlled access is a plus.

Perfect For:

The UltraMD33 is a go-to choice for areas where space is tight and moisture control is essential:

Condos & Townhomes

Apartments

Senior Living Facilities

Student Housing

Hotels

Beyond keeping humidity comfortable, it also helps prevent costly issues like mold, property damage, and guest complaints—making it both a comfort and a safeguard.

Features

Built to fit snugly between two wall studs, this unit requires an opening measuring 14.5 inches wide by 30.25 inches tall. Because it needs to vent through both sides, installation must be done on an interior wall. You can either hardwire it into your home’s electrical system or use a standard 120-volt outlet—an optional 10-foot cord and plug is included for convenience. Depending on your setup, you may need to purchase a few extra accessories to complete the installation. Here’s when that might apply:

No additional accessories are needed if penetrating both walls and the opposite side is a mechanical room.

If the back wall is functional space, installation requires a 2x4 Wall Mount Bezel Kit (PN 4037767).

If the other side of the wall goes into an unconditioned space, it may require the 2x4 Rear Panel Kit (PN 4037768) to add a layer of insulation to prevent condensation.

For surface mount installation, the surface Mount Kit (PN 4037766) is required.

Note: While professional installation is recommended, it’s not required. Be sure to shut off your electrical breaker before installation. See the owner’s manual for additional installation directions and requirements.

More Noteworthy Features

Optional Moisture Sensor: Add an external moisture sensor to your in-wall unit for added peace of mind, especially in areas prone to dampness.

Extended Warranty Coverage: The UltraMD33 includes a robust 4-year warranty. Its galvanized steel housing is designed to resist rust and stand the test of time.

Energy-Conscious Performance: This model removes 4.25 pints of moisture per kilowatt hour, offering efficient and effective moisture control.

Wide Temperature Range: Operates reliably in environments between 49°F and 95°F.

Power Outage Recovery: After an outage, it automatically returns to its prior settings without manual resets.

Low Noise Operation: At just 46 decibels, it’s as quiet as a typical refrigerator—ideal for residential use.

Streamlined Aesthetic: A sleek front panel slips over the unit, helping it blend seamlessly into your living space.

Certified for Safety: The MD33 meets unified ETL, UL, and CSA standards for peace of mind and safe performance

Draining Made Simple

This unit comes with a 10-foot drain hose that connects directly to the drain port. You’ll need to route it through the interior wall cavity and into an HVAC AHU drain (which links to the HVAC drain pan) or another approved drainage outlet. Depending on the setup, the water can flow out by gravity, or you can install an external condensate pump to move it where needed. Once it’s in place, there’s no need to worry about emptying tanks or handling manual drainage—it runs on its own. Just make sure to review your local building codes before installation.

Enhanced 6-Year Warranty

Santa Fe has extended its warranty coverage, now offering up to six years of dependable protection—backed by a commitment to performance and customer satisfaction. This leading “Peace of Mind” warranty applies to all Santa Fe dehumidifiers made on or after January 1, 2024. It includes a 5-year warranty covering operational issues and an additional 6-year warranty on component failures. Should your unit experience an issue, Santa Fe will either repair or replace it. For full details, always refer to your Owner’s Manual for specific warranty terms and conditions.

Additional Upgrades and Accessories

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.

FAQs

What is the most common problem in basements?

Moisture is the most common problem in basements. Excess moisture leads to mold growth, and mold growth leads to property damage, bad indoor air quality, increased odors from off-gassing of mold spores, and damage to items stored in the basement.

Why do I need to control moisture in my crawl space?

Excess moisture, introduced by way of unsealed, vented crawl spaces, contributes to wood rot, mold growth and increased pest activity, including infestation and colonization. Moisture in crawl spaces often migrates to the upper levels of the home through a “stack effect.”

Why should I buy a Santa Fe dehumidifier?

Energy Efficient. Large capacity. Commercial quality. Designed to show moisture who’s boss. Reliability. Superior Filtration (MERV-13). These are the reason you can’t go wrong with buying a Santa Fe dehumidifier. Oh, and an industry-leading warranty.

Where do musty odors in my home come from?

Musty odors are typically a result of high humidity levels in the crawl space and basement. This polluted air below the house will eventually move to the rest of the house, carrying musty odors and other contaminates. Specifically, musty odors in your home come from the off-gassing of mold spores when they feed on organic materials. Solve the moisture problem and you will solve your mold problem.

How does wood rot occur in a home?

Wood rot in floor joists and support piers occurs when the moisture content is above the fiber saturation point, which is about 27-28% wood moisture content.

What pests cause damage to a home?

The top 8 common pests that can cause damage to a home are: termites, carpenter ants, powder post beetles (aka powder beetles), carpet beetles, cigarette beetles, grain weevils, house mice, and Norway rats.

Does poor air quality affect your health?

According to the Environmental Protection Agency, health problems associated with poor indoor air quality include eye irritation, allergies, headaches and respiratory problems such as asthma. These problems can be directly related to the presence of mold and dust mite infestation in the home. One of the recognized solutions to addressing these health issues is effective moisture control.

Can I have high humidity in my home?

High humidity can greatly affect your comfort by causing you to feel either hot and sticky or cold and clammy, especially in your basement, while also contributing to smelly, musty odors in the home. Musty odors come from off-gassing of mold spores when they feed on organic materials. Solve the moisture problem and you will move your mold problem.

Are Santa Fe dehumidifiers energy efficient?

All Santa Fe dehumidifiers exceed Department of Energy standards. When you see our logos, you know that you are purchasing a dehumidifier with superior energy efficiency that will help you save money. Our dehumidifiers are built to remove more moisture using the same amount of energy as conventional units.

Where does moisture in a home come from?

There are three main sources of moisture in your home: the first source is leaks, the second is diffusion through materials, and the third is internally generated moisture.

What is stack effect?

Stack effect is the movement of warm, dry air rising and escaping through the upper levels of the home and cooler, wet air finding its way into the lower levels in order for the home to equalize.

What factors should be considered when choosing the capacity of a dehumidifier?

The number one factor to consider when choosing how many pints of water removal you will need for your space is infiltration from the ground below and the air outside – experts say about 95% of the moisture entering a building enters through air infiltration. It’s also important to make sure your basement or crawl space is sealed, as this also is factored in the total size of a space.

Why is air movement important?

Air movement breaks down boundary layers at surfaces, promotes air mixing, reduces stagnant micro-environments and helps convert heat energy to the structural components you want to protect.

What does the Santa Fe six-year warranty cover?

Therma-Stor, LLC (“Therma-Stor”) warrants as follows: (i) Santa Fe dehumidifiers (“Product”) will be free of material defects in workmanship or materials for a period of 5 years (“Five-Year Warranty”) following the date of initial purchase of such Product by an original customer purchasing from Therma-Stor or an authorized reseller (“Customer”); and (ii) the Product’s components will be free of material defects in workmanship or materials for a period of six (6) years following the date of initial purchase of such Product by a Customer.

Why ventilate?

The purpose of ventilating a home is to maintain a healthy and safe living environment.

The reason for the buildup of indoor pollution in today’s homes is a direct result of our efforts to conserve energy and save money. As the techniques and materials used to insulate and seal our homes has improved, the result is stale and polluted air trapped inside.

Common sources of indoor airborne contaminants include:

Chemicals used in the construction or renovation of buildings
Appliances that burn gas
Wood-burning stoves and fireplaces
Pets
Off-gassing of furniture, cabinets, flooring, and countertops
Infiltration of ozone, pollen, and molds from the outside
People
Cleaning supplies
