Questions and answers
My pool is built, can I install a counter-current swimmer?
Yes, there are solutions that are compatible with existing pools. However, it is ideal to plan the installation during construction, as it allows a more aesthetic and functional integration.
At the very least, we recommend installing the housing box from the beginning.
what is the difference between Basic NL, Basic ND and Advance ND models?
The main difference is in the finishes, flow rate and system control.
- Basic NL: Most basic model, with plastic front.
- Basic ND: Stainless steel finish, adjustable flow rate from 27 to 40 m³/h.
- Advance ND: Higher performance and more modern design, with adjustable flow rate from 25 to 50 m³/h and variable speed control.
what is included in a countercurrent swimming kit?
Generally, complete kits include:
- Drive pump
- Control cabinet
- Discharge nozzle with air-water mixing system
- Housing box
- Suction grids
- Hand grip on some models
what is the velocity of the water in these systems?
Depending on the model, they can reach speeds of:
- 12 m/s at the outlet
- 2.4 m/s at 1 meter
- 1.5 m/s at 2 meters
These figures allow for a realistic and progressive counter-current swimming experience.
are they suitable for liner pools?
Yes, but an additional add-on (reference 11503) is required to ensure correct installation.
Countercurrent Swimming for Pools: Exercise and Fun without Limits
Swimming pool counter-current systems are accessories that allow for intensive swimming, aquatic exercise and physical therapy in limited spaces. Thanks to their ease of use, these systems transform any pool into a complete training and entertainment center.
why choose a counter-current swimming system?
Opting for these systems offers multiple advantages:
- Unlimited training: Ideal for training endurance, swimming technique and muscular strength without the need for a large pool.
- Versatility and optimized space: It fits perfectly even in small pools, allowing intensive swimming sessions.
- Wellness and health: Perfect for therapeutic exercises and aquatic rehabilitation.
- Savings and practicality: Facilitates aquatic exercise at home, saving time and costs related to external sports facilities.
how do counter-current swimming systems work?
These systems work by generating a powerful flow of water through hydraulic pumps integrated into the pool. This flow creates an artificial current against which the user swims, simulating an infinity pool.
The intensity and power of the current are usually adjustable, allowing the exercise to be adapted to the level and personal objectives of each user.
what are the components of counter-current swimming equipment?
The following are the main components of a counter-current swimming system:
Propulsion pump
- This is the heart of the system. It is responsible for generating the necessary flow to create the water current.
- Some important aspects when choosing the pump are:
- Flow rate and power: they must be adapted to the user's level (recreational or professional training).
- Location: follow the manufacturer's recommendations.
As a general rule are high-powered engines.
Control panel
- These devices have the necessary mechanism for the safe control of the motor.
- As a general rule, pneumatic or piezoelectric pushbuttons
Front panel
It is the visible part of the system inside the pool. It is where the water is expelled to generate the current.
The front panel is composed of two parts:
- Front (actual face plate): usually made of ABS, stainless steel or chlorine resistant materials. It has a hydrodynamic design to properly channel the flow.
- Body or housing: it is installed in the pool shell during the construction work (in concrete pools) or in the panel (in prefabricated pools), and serves as a base for mounting the front panel.
Kit or complete pack
To facilitate the choice and installation, many manufacturers offer complete packs that integrate the three components (pump, control panel and cover).
These kits are designed to cover different needs and avoid compatibility errors between parts.
