YAKE Ducted Dehumidifier RYDZ-168A

The YAKE RYDZ-168A is a high-capacity ceiling or wall mounted dehumidifier engineered for confined spaces such as subfloors and roof cavities. This commercial-grade unit combines dehumidification with advanced air purification through UVc sterilisation, negative ion generation and three-stage filtration, making it ideal for demanding environments where air quality is critical.

Key Features

• High-capacity dehumidification removing 160 litres per day at 30°C, 80% humidity conditions
• Integrated UVc steriliser and negative ion generator for enhanced air purification
• Three-stage filtration system featuring G4 pre-filter, HEPA filter and activated carbon filter
• Reliable Panasonic compressor with delayed start-up protection for extended equipment life
• Weather-resistant IPX04 waterproof rating with IP44 protection class compliance

Typical Applications

The RYDZ-168A is designed for permanent installation in commercial facilities where concealed moisture control is required. Its ceiling or wall mounting capability suits spaces where floor area is limited or where ductwork needs to distribute conditioned air across multiple zones.

Common installations include:

• Hotels and hospitality venues with enclosed corridors or basement levels
• Office buildings requiring central humidity management across multiple rooms
• Hospital and healthcare facilities where air quality standards are mandated
• Indoor swimming pool halls and gymnasium complexes
• Laboratories and cleanroom environments with strict humidity tolerances
• Subfloor spaces and roof cavities prone to condensation buildup

How the RYDZ-168A Handles Ducted Dehumidification

Unlike portable or standalone units, a ducted dehumidifier system draws air through inlet ductwork, conditions it, and returns dry air through outlet ducts to the treated space. The RYDZ-168A delivers 1,800 m³/hr of processed airflow at 70 Pa static pressure, which provides enough force to push conditioned air through typical commercial duct runs.

This approach keeps the dehumidifier out of the occupied space entirely. The unit sits in a ceiling void, plant room or service corridor while ductwork handles distribution, which eliminates noise in the working environment and allows a single unit to serve multiple rooms or zones.

Installation and Ductwork Requirements

Proper planning before installation prevents undersized ductwork, drainage issues and inadequate airflow. The RYDZ-168A accepts a 250 mm diameter inlet duct and a 200 mm diameter outlet duct.

Key installation considerations include:

• Mounting location must support 120 kg and allow access for filter changes
• Condensate drainage requires a gravity fall or a condensate pump to a suitable drain point
• Three-phase 400V/50Hz power supply with a dedicated circuit rated for 6.0 A draw
• Return air path must be unobstructed to maintain rated airflow through the duct system
• Operating temperature range of 5°C to 38°C suits most Australian commercial environments year-round

Humidity Controls and Air Quality

The RYDZ-168A includes an integrated humidistat that allows facility managers to set a target relative humidity level. The unit cycles automatically to maintain the setpoint, reducing energy consumption during periods of lower moisture load.

Beyond moisture removal, the three-stage filtration system addresses airborne contaminants:

• G4 pre-filter captures coarse dust and debris, protecting the HEPA stage
• HEPA filter removes fine particulates down to 0.3 microns
• Activated carbon filter adsorbs volatile organic compounds and odours
• UVc sterilisation neutralises airborne bacteria and mould spores passing through the unit

This combination of humidity control and air purification makes the RYDZ-168A particularly relevant for healthcare settings and laboratories where both moisture levels and air cleanliness are regulated.

Choosing Between Ducted Dehumidifier Models

The RYDZ-168A sits in the mid-range of Moisture Cure’s ducted lineup. Selecting the right unit depends on the volume of the space being treated, the moisture load present and whether the existing HVAC system will supplement or replace dehumidification duties.

Key factors to evaluate:

• Room volume and target humidity level determine required extraction capacity
• Moisture sources (swimming pool evaporation, process steam, ground moisture) affect continuous load
• Available static pressure must exceed duct system resistance for proper air distribution
• Integration with existing mechanical ventilation may allow shared ductwork

Our ducted dehumidifier specification guide walks through capacity calculations and duty-point matching for commercial projects. For facilities with indoor pools, the pool hall dehumidification guide covers the additional evaporation load calculations required.

Frequently Asked Questions

Can the RYDZ-168A be ducted to multiple rooms from a single unit?

Yes. The 1,800 m³/hr airflow and 70 Pa static pressure allow the unit to serve multiple zones through a branched duct system.

Each branch can be fitted with a manual or motorised damper to balance airflow between rooms. The total duct resistance across all branches must stay below the rated static pressure for the unit to maintain its extraction capacity.

What maintenance does a ducted dehumidifier require?

The G4 pre-filter should be inspected monthly and replaced when visibly loaded. The HEPA and activated carbon filters follow the manufacturer’s replacement schedule, typically every 6 to 12 months depending on dust load.

The condensate drain line should be checked quarterly to prevent blockages. The UVc lamp has a rated lifespan and should be replaced per the service manual to maintain sterilisation effectiveness.

Is the RYDZ-168A suitable for indoor swimming pool dehumidification?

It can handle smaller pool halls and spa areas. Pool environments produce a continuous and heavy moisture load from water surface evaporation, so the 160 litres per day capacity needs to be matched against pool surface area, water temperature and room ventilation rate.

Larger pools may require a higher-capacity ducted unit or multiple units in parallel. See the pool dehumidifier sizing guide for detailed calculations.

Does the unit need a condensate pump or can it drain by gravity?

Gravity drainage is the preferred method where a fall to a floor drain or waste pipe is available. When the unit is ceiling-mounted and no gravity fall exists, a condensate pump lifts the collected water to the nearest drain point.

At full capacity the RYDZ-168A produces approximately 6.66 litres of condensate per hour. The pump and drain line must be rated accordingly.

What is the difference between a ducted dehumidifier and a portable unit?

A ducted dehumidifier is permanently installed out of sight and distributes conditioned air through ductwork. This removes noise from the occupied space and allows one unit to serve multiple rooms.

A portable unit sits in the room it treats, produces audible compressor noise and only conditions the immediate area. For commercial facilities that need continuous, unattended humidity control, ducted systems are the standard approach.
