MP-175 Desiccant Dehumidifier — Low-Humidity Control Below Refrigerant Limits

Made to order — estimated 5-week lead time.

The Bry-Air MiniPAC MP-175 is a 175 CFM desiccant dehumidifier designed for spaces where refrigerant systems lose capacity or stop operating entirely. It delivers 5.8 lbs/hr moisture removal independent of ambient temperature, making it suitable for cold storage staging areas, pharmaceutical rooms, and laboratories targeting sub-30% RH. This stainless steel configuration is specified for environments requiring corrosion resistance and controlled sanitation.

Bry-Air MP-175 Low-Temperature Moisture Removal

The MP-175 maintains consistent drying performance across a wide temperature range without defrost interruptions or capacity loss.

  • Consistent output at low temperatures — maintains 5.8 lbs/hr removal where refrigerant units lose efficiency or shut down
  • 175 CFM process airflow — supports medium-sized labs, packaging rooms, and cold storage ante-areas without oversizing equipment
  • Stainless steel construction — resists corrosion in washdown environments and high-humidity intake conditions
  • No defrost cycle — eliminates downtime caused by coil icing in low-temperature applications
  • Integrated airflow safety monitoring — prevents operation under restricted airflow conditions caused by filter loading or fan issues
  • Flexible installation options — adapts to floor, wall, or ducted configurations in constrained mechanical spaces

MP-175 Applications and Environments

The MP-175 is deployed in pharmaceutical manufacturing for tablet coating and packaging where moisture control directly impacts product stability. Laboratories and materials testing facilities use it to maintain controlled low-humidity conditions for hygroscopic samples and calibration equipment. Cold storage operators install it in staging areas and ante-rooms adjacent to freezer vaults where refrigerant systems cannot operate. Electronics manufacturing and military storage facilities rely on it to reduce corrosion risk on sensitive components. It is also used in archival storage, seed banks, and museum collections where stable humidity levels must be maintained year-round.

MP-175 Desiccant Wheel Operation and Exhaust Requirements

The MP-175 uses a rotating desiccant wheel that adsorbs moisture from the process airstream and continuously regenerates through a heated reactivation airflow. This design removes moisture without a compressor or evaporator coil, allowing operation from sub-freezing temperatures up to 140°F. The reactivation airstream must be ducted to the exterior, as it carries the extracted moisture away from the conditioned space. The stainless steel housing supports installations in environments requiring corrosion resistance or periodic washdown.

Shipping & Returns

Free shipping on most brands for orders over $300, delivered to the lower 48 states. Any brand-specific freight rate is shown at checkout before you pay.

Processing & delivery: in-stock orders are processed within 1–2 business days and typically deliver in 5–7 business days. Tracking is emailed within 24 hours of shipment. Built-to-order and backordered equipment shows its lead time on this page.

Freight deliveries: inspect your equipment on arrival and note any damage on the delivery receipt. Items damaged in transit or defective on arrival are fully covered at no cost to you.

Cancellations: cancel any time before your order ships. Refunds are issued for the order total minus the non-refundable payment processing fee (2.9% + $0.30), so a cancellation is not always a 100% refund. No fee is deducted if we cancel the order or the item arrives damaged or defective.

30-day returns: return unused equipment in its original packaging within 30 days of delivery. Change-of-mind returns are subject to a restocking fee. To start a return, email info@uscleaningtools.com or call +1 (978) 295-7538.

Frequently Asked Questions

How does the MP-175 differ from the MP-100 — when should I choose the larger unit?
The MP-175 processes 175 CFM versus the MP-100's 100 CFM — a 75% increase in process air volume — and removes approximately 5.8 lbs/hr of moisture versus 3.3 lbs/hr. Both units run on single-phase 208–240V power, so the choice is primarily about room size and moisture load. The MP-175 is appropriate for medium laboratories, pharmaceutical packaging rooms, or cold storage staging areas where the MP-100's 100 CFM throughput would be undersized. Both models share the same desiccant wheel architecture, safety systems, and water-washable rotor.
What is the minimum relative humidity the MP-175 can achieve?
Desiccant dehumidifiers can reduce relative humidity well below the limits of refrigerant equipment — below 10% RH is achievable under favorable inlet conditions. The actual minimum for the MP-175 depends on inlet air temperature and humidity, process airflow rate, and reactivation heat input. Request specific performance curves from Bry-Air for your application conditions before sizing.
What temperature range can the MP-175 operate in?
The MP-175 operates from approximately -4°F (-20°C) to 140°F (60°C). Refrigerant dehumidifiers lose significant capacity below 60°F and typically cease effective operation below 35°F due to evaporator coil icing. The MP-175's desiccant rotor adsorbs moisture through a chemical process with no icing threshold, making it the correct choice for cold storage ante-rooms, freezer staging areas, and low-temperature industrial environments.
Does the reactivation exhaust from the MP-175 need to be ducted to the exterior?
Yes. The reactivation air stream carries the moisture extracted from the process air and exits as warm, humid exhaust at 58 CFM. This exhaust must be ducted to the building exterior. Dumping the reactivation exhaust back into the conditioned space returns the extracted moisture and eliminates the dehumidification effect. Route the exhaust duct through an exterior wall, roof penetration, or existing building exhaust pathway.
What does the differential air pressure switch do on the MP-175?
The differential air pressure switch monitors the pressure drop across the MP-175's air path during operation. If a filter becomes clogged, a blower fails, or airflow drops below the operating threshold for any reason, the switch triggers an alarm or initiates a controlled shutdown. This protects the reactivation heater from overtemperature and notifies facility personnel of a maintenance condition — critical in unattended installations where a blocked filter would otherwise go undetected.
Can the MP-175 rotor be serviced without factory support?
Yes. The desiccant rotor in the MP-175 is water-washable and can be removed and rinsed on-site to clear accumulated dust and particulate without chemical cleaning agents. The stainless steel flange resists corrosion during the wash process. Follow Bry-Air's published rotor maintenance procedure to avoid damaging the desiccant matrix during washing — the procedure does not require specialized tools or factory technicians.
What electrical circuit does the MP-175 require?
The MP-175 requires a dedicated 208–240V single-phase 60Hz circuit. It is not compatible with standard 115V or 120V outlets. A dedicated 20–30 amp 240V circuit is typically required depending on total connected load. Verify panel capacity and circuit sizing with a licensed electrician before installation; the unit must not share a circuit with other high-draw equipment.
