ResiDUCT™

With all the advancements in MVHR units, why overlook the ducting?

Especially when it’s significantly responsible for installed performance.

If MVHR needs to deliver higher airflow rates due to overheating - ResiDUCT™ is your ideal choice.

ResiDUCT™ is an innovative ducting solution designed to meet the increasing demand for superior ventilation performance in residential homes.

ResiDUCT™

Part O:Overheating
Where overheating planning conditions are in place for residential dwellings, ventilation airflow rates are typically increased. More airflow = larger ducting.

The ResiDUCT™ range offers a low profile, high performance ducting option which is ideal for typical ceiling void sizes.

Installed Performance
Air leakage from duct connections within an MVHR system installation can be signficant. The MVHR unit ends up having to compensate when it is commissioned, increasing operational noise and energy consumption for end users.

The ResiDUCT™ system addresses air leakage with an innovative design that simplify connections, adds strength and prevents bowing as parts are connected together.

At a time when installed performane is crucial to maintain comfort, ResiDUCT™ can offer performance advantages.

Reduce Air Leakage - Reduce MVHR Noise - Reduce Energy Usage

Ducting that Powers Performance.

Air leakage is the hidden enemy of an efficient ventilation system. In a single run of ducting, there can be many air leakage points as ducting is connected together which adds up across each system install.

This leads to increased energy consumption and running noise as the MVHR unit has to compensate when commissioned. ResiDUCT™ addresses air leakage with two innovative design features;

1. Integral Stiffeners

ResiDUCT™ stiffeners are manufactured into all female parts and connectors, offering a unique strengthening feature for the ductwork that enhances performance and reduces air leakage.

The stiffeners help maximise airflow capacity by adding strength as the parts are pushed together - supporting common weak points found in other types of jointing e.g. slip joints.

Registered Design.

2. Socket Seal Joints

ResiDUCT™ male and female parts are designed to fit seamlessly together with socket seal joints.

The jointing system prevent bowings and leakage gaps as the parts are pushed together.

Socket seal joints aid installation time and easily connect to plastic ducting systems where the use of hybrid systems (metal and plastic ducting) have been designed to achieve higher airflow performance.

Overheating - MVHR & Increased Duct Sizes

Overheating = Increased Ventilation Rates = Larger Duct Sizes

A MVHR unit may be powerful enough to deliver higher airflow rates demanded under Part O, but installed performance will also be dependent on the ducting that it connected to it. To achieve the higher performance, the duct size usually has to be increased, potentially up to 180 or 200mm for supply and extract, however it’s not always simple to apply this in residential applications.

The typical ceiling void in a residential dwelling is around 150mm.

Part O: Overheating may demand increased ventilation airflow rates which will require 180-200mm ducting,
which is not always feasible due to spacial restrictions within each dwelling.

ResiDUCT™ is a low profile ducting solution designed to deliver higher airflows, typical with overheating with ease.

ResiDUCT is available in standard sizes:

300 x 100mm equivalent to 180mm ⌀

300 x 125mm equivalent to 200mm ⌀

400 x 100mm equivalent to 205mm ⌀

400 x 100mm equivalent to 230mm ⌀

Hybrid Ready - Easily installed with PVC Ducting

Where increased ventilation rates are required to meet overheating planning conditions, a cost effective ducting design is being adopted for MVHR systems - hybrid ducting.

Both metal and PVC ducting are designed to work together to help strike a balance between flexibility and airflow performance - and an ideal solution for residential applications.

ResiDuct™ is hybrid ready

The ResiDuct™ Range is designed to be compatible with metal and PVC ducting in various sizes thanks to its new socket seal connections which help bridge the gap between materials with seamless connections, no matter the setup.

How does ResiDUCT™ reduce air leakage?

ResiDUCT™ has unique integral stiffeners that ensure a more airtight connection. The stiffeners are welded into all female parts and help maximise airflow capacity by adding strength as parts are pushed together, supporting common weak points found in other types of jointing e.g. slip joints.

Air Leakage reduced by 52% when compared with other ducting systems. Air Leakage independently tested and verified. Information available on request.

What are socket seal joints used in in the ResiDUCT™ system?

Socket Seal joints allow male and female parts to connect together seamlessly without bowing and leakage gaps as parts are pushed together. Socket seal joints air installation time and easily connect with other types of ducting including PVC.

Why is ResiDUCT™ ideal for overheating?

Overheating demands higher ventilation rates in homes to maintain comfort. Higher ventilation rates can be achieved by MVHR units, but the ducting and duct size has a significant impact on whether those rates can be achieved.

ResiDUCT™ is a low profile ducting system designed to fit in the same space as typical PVC ducting used in MVHR systems whilst delivering higher airflows - equivalent to 180 - 225mm circular.

What are the advantages of ResiDUCT™ ?

ResiDUCT™ offers many advantages for MVHR installations;

Reduced Air Leakage due to integral stiffeners and sockset seal jointing
Energy Savings and Noise Reduction from MVHR units running at lower speeds due to reduced air leakage in ducting network
Quicker and simpler installation from sociak seal jointing as male and female parts easily connect together onsite
Hybrid compatible - can easily be installed with PVC 220 x 90 or 204 x 60mm ducting where required
