Indux 4 – Through The Wall Grille with 2 Ducts – Fresh Air Heat Recovery Ventilator
The Indux 4 Heat recovery ventilation unit is designed to sit in a wall but has the added feature that allows you to use 2 ducts to vent the air through to an outer wall if you do not have an outside wall to install this unit on.
This unit will extract stale air and introduce warmed fresh air from the outside.
As a heat recovery ventilation unit it moves a useful 153 l/s of air
Processing the same air over and over will make the pool hall air feel stuffy and stale, which is why is always a good idea to make provision for fresh air.
The Indux 4 is the perfect solution for commercial areas that require a high performance balanced intake/extract scheme.
Ideal for swimming pools, computer rooms, classrooms, offices and the health and leisure industries.
The compact heat recovery cube interleaves outgoing warm air with incoming fresh air and allows the heat from one to warm the other without the two streams mixing. No energy is need for this mixing, just the small fans.
Behind the neat deflecting fascia grilles are the filters, the heat exchange cube and fan units. All wall sleeve components, the heat exchange cube and the fascia grilles are made of tough polymeric materials.
The Indux 4 can be controlled with the addition of the speed controller. This cost a little extra but is a worth while purchase.
This unit is fully speed controllable with the facility to reverse the supply air fan and provide ‘double extraction’ for periods when heat loss is desirable.

The Indux ventilation range are ideal for swimming pools, computer rooms, classrooms, offices and the health and leisure industries.
The Indux units are the perfect solution to commercial areas that require a high performance balanced intake/extract scheme.

No energy is needed for this mixing, just the small fans.
The unit will fit in walls of up to 600mm thick.
Behind the neat deflecting fascia grilles are the filters, the heat exchange cube and fan units.
All wall sleeve components, the heat exchange cube and the fascia grilles are made of tough polymeric materials.
All of these units can be controlled with the addition of the speed controller.

Flow rate of up to 300m3/hr can be achieved in boost mode, or just 70 on low speed.
General Information which will help you decide which unit you need:
Fresh air ventilation can play an important part in keeping your indoor pool hall air comfortable.
Introducing fresh air will help remove odours that can sometimes be present in a swimming pool environment.
Heat Recovery Ventilators are very good at recovering heat from the old extracted air.
This heat recovery will save you lots of money in the long term.
The cost of running these small fans is relatively low, however the energy used to heat up this air is not.
Which is why it is so important to recover as much as possible.
Up to 70% heat recovery can be obtained from the extracted air, which is not bad for a small outlay and simple installation.
The Heat Recovery Ventilators operate with fans. Two fans operate, one bringing in fresh air the other extracting old stale humid air.
Both bodies of air pass each other in a simple cross over chamber. This chamber recovers heat back to the fresh air that is being introduced to the pool hall.
The speed of the fans are controlled by voltage, the more voltage the faster the fan runs, the faster the fan runs the larger volume of air will be introduced (and extracted).
The speed controller that controls the fan speed has a number of settings.
This helps regulate the amount of fresh air.
Please note that the units we recommend for commercial use are the Indux 1 and 4 units
Each pool is different which is why three main installation types are available:
Option 1 – Through the wall Units (Indux 1 or Indux E300)
The unit grills will be seen in the pool hall and on the external wall. Easy to install and wire up, offers a good value solution. To control the speed you will require the correct speed controller to suit your fan.
Option 2 – Semi Remote (Indux 4 and E300 RW6)
This type of installation will require a little more work as ducting (150mm E300 and 300mm Indux 4) will be required along with grilles. Please note ductwork and grilles are not supplied with the fans. You will have to purchase these separately to meet you project requirements. Again to control the speed you will need the correct speed control for your fan unit.
Option 3 – Fully Remote (E300R6)
This is suitable for installation in roof void or similar internal space. Please note these units are not suitable for installation in wet areas or externally. The unit will have 4 spigots that you will connect 150mm ductwork too. Please check the installation and specification guides if you wish to install long runs of ductwork. These are relatively small fans so large pressure drops within the system may reduce the extraction rates. That said they are suitable for most domestic type installation. Call us for more details or download the data/installation guides from the resources tab above.
The different types of unit will have different extraction rates in Meters cubed per hour:
