Choosing ETT means choosing comfort and well-being for your users, as well as energy efficiency for your equipment
A hotel or healthcare establishment is a tertiary-sector building (EOP) subject to numerous issues and technical constraints that need to be taken into consideration.
Comfort:
The special feature of a pool hall is that there are both wet people coming out of the water and dry people (lifeguards, accompanying adults, spectators, etc.).
Because water evaporates from the skin, the notion of comfort is completely different for each of these categories of people moving in the same volume.
The aim of the air handling system is to achieve the best temperature/hygrometry compromise so that everyone feels comfortable.
The ETT control system, specially developed for swimming pools, adapts perfectly to this constraint by operating in the common comfort zone (14 and 16 g/kgas) and regulating directly on the water weight setpoint.
Air quality is the second most important aspect of a Pool Hall, as it limits as far as possible the presence of trichloramines, which are responsible for irritation of the eyes and throat.
Firstly, effective water treatment and cleanliness of bathers will be essential to limit evaporation of this molecule as much as possible, the presence of trichloramines. On the other hand, correct sizing of the ETT dehumidifier's fresh air flow rates can limit the undesirable effects on all users.
A ‘Dechloraminator’ function is available on our remote box, to switch the system to ‘Fresh Air’ for a set period of time.
Cooling:
Most hotel swimming pools have no opening to the outside. Temperatures can then rise quickly, well above the comfort zone for bathers.
ETT dehumidifiers cool the air, limiting temperature drift.
Energy efficiency:
These often private establishments have realised the impact of a swimming pool on their energy bills.
ETT develops the most efficient systems in its market, aware of all the financial and environmental challenges.
Sound level:
The air handling system is regularly seen in the pool area, an adjacent room, or even outdoors near customers or neighbours.
ETT systems are extremely quiet and can be installed anywhere.
Space requirement:
ETT designs compact systems that are specially sized to fit easily through building doors. This approach makes them much easier to install and integrate into technical rooms.
The durability of the work:
To ensure optimum performance over time, it is essential that the interior conditions are right.
ETT regulation will prevent any risk of condensation on the walls, thereby preserving the building envelope and structure.
This must comply with the state of the art in terms of thermal insulation and airtightness.
ETT's solutions for meeting the aeraulic and economic challenges of swimming pool establishments include various functions:
An essential function in swimming pools, it removes a large proportion of the water vapour generated by evaporation in the pools, which is detrimental to user comfort.
This function aims to use outdoor air to cool a space when conditions are favourable.
Heat exchangers are frequently used to preheat fresh air. ETT offers a wide range of technologies, including plate, rotary, heat pipe and glycol water heat exchangers.
Adapted to corrosive environments, ETT machine components can have specific coatings for saline and sulphurous environments, such as varnished piping and brazing, titanium and insulated water exchangers, heresite-coated battery protection, etc.
The operator must ensure that his equipment does not generate any particular noise which, by its duration, repetition or intensity, is detrimental to the peace and quiet of the neighbourhood.
ETT has a wide range of technical solutions to combat noise pollution from air handling systems.
Dimensional constraints are very often the source of integration difficulties when replacing existing equipment.
ETT's strength lies in its ability to offer completely customised machines that fit in with their environment.
ETT has developed a remote supervision tool integrated into their machines. The aim is to provide operators with monitoring capabilities for their machines, and to enable ETT to provide fast and reliable expertise. Other services are also integrated.

Regulations
Swimming pool regulations mainly concern health rules relating to water treatment.
Air flow rates are calculated on the basis of their dehumidification capacity.
However, the 60 m3/h of fresh air per occupant must be complied with.
