PRO Swim Spas

A swimming pool, swimming bath, wading pool, or paddling pool is a container filled with water to enable swimming or other leisure activities. Pools can be sunk into the ground or built above ground (as a freestanding construction or as part of a building or other larger structure). In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic or fiberglass, and can be of a custom size and shape or built to a standardised size.

Spa pools are pools filled with hot water, used for relaxation or hydrotherapy, and are common in homes, hotels, clubs and massage parlors. Special swimming pools are also used for diving and other water sports, as well as for the training of lifeguards and athletes.

From spa industrial fashion trend, the freestanding swimming pool with hydro therapy, made with acrylic and fiberglass is more and more popular, easy for customers to get and install, it's called swim spa. This type swim spa are mostly installed with powerful whirlpool pump to drive swim jet to produce strong water flow against swimmer, offer swimming exercise. Due to the water flow out of swim jets, it is still be influenced by the resistance from jet and hose, jet type swim spa may be enough for common home use, but may not be enough powerful for an athletes or other strong swimmer.

Today we, J&J, would like to present our PRO series of swim spas in the market, to meet the demand of athletes and professional swimmer fully. The Pro swim spa is equipped with 2.8Kw to 5.6Kw axial-flow pump, with adjustable nine speeds. The axial-flow pump, or AFP, is a type of pump that essentially consists of a propeller (an axial impeller) in the swim spa. The propeller can be driven directly by a sealed variable frequency electric motor mounted to a circle hydroecium to produce powerful water flow, to offer endless swimming sport in a limited space. How powerful it is? From our testing, a 2.8Kw PRO swim spa runs at 5-6 speeds is enough for an adult woman, and 6-7 speed is enough for an adult man, and the 8-9 speeds are leaving for challengers.


 Advantages of inground swimming spas
Many of us would love to have the Advantages of the inground swim spa, but we don't really understand what they are. But, if you ask a pool designer or a pool owner, they will know right away. They will tell you that inground spas provide a wide range of benefits and advantages for swimming pools. These are some of the benefits of inground swim spa:
In an inground swim spa, there is no need to worry about the dirt accumulating in the pool. Because there is no filter to trap the dirt, the water stays clean. In addition, because the water is not being filtered by a filter, it can help to keep the water from becoming too chlorinated. Because the water is naturally chlorinated, the water will be able to remove a lot of the toxic chemicals that we find in our tap water.
Additionally, many of the systems that are used to protect the pool from the chemicals that we find in our tap water do not cleanse the water as well as an inground swim spa does. For example, the power-washed machines do not do as well a job as an inground swim spa does. Also, these power-washed machines can create toxins that are harmful to the body. Thus, it is important to have an inground spa around.
The advantages of inground spas are also the reason that they are such a popular choice with owners. As we mentioned earlier, there is no filter involved in the system. This means that the water does not have to be filtered to prevent the build-up of toxins that are harmful to the body.
The advantages of inground spas are also why they are popular with pool designers. With an inground spa, there is no need to worry about the water going bad. You don't have to spend money on water filters. Furthermore, since there is no filter, there is less chance of having debris build up in the pool. This means that you won't have to worry about losing a lot of money on filters.
Water that is not filtered is often contaminated with chemicals and other things that are harmful to the body. If the water in your pool is not properly filtered, you run the risk of introducing some of these toxins into the water. However, if you install an inground spa, the toxins that are introduced are removed before they can do damage to your body.
In addition, an inground swim spa is more environmentally friendly than power-washed pools. While power-washed pools can cause large amounts of damage to the environment, an in-ground swim spa can be less damaging to the environment. Many of the costs associated with constructing a pool can be offset by using a water-activated spa, thereby reducing the overall cost of installing the pool.
In short, Advantages of inground spas are a great benefit for those who are looking to enjoy the benefits of swimming in a pool with little concern for maintaining it. An inground spa is also one of the reasons that people who have a pool install one. So, if you're considering installing an inground spa, keep these benefits in mind.

Spillway Equipment

In order to ensure the normal circulation of the water of the whole pool to flow, and the flow water in the pool can be calm with potency dimension, we according to size of the swim pool deploy different quantity of backwater port, and then install the return grid around the pool, let the water more steady, at the same time, let the swimmers swim forward all the time as if they are swimming in the sea without the dangerous of vortex or surge.

Swimming and rehabilitation training


Swimming and rehabilitation training

With antiskid massage panel in the bottom of our swimming pool, water outlet and water return ostium ensure the water flow's balance. At the same time, they make the water flow attached strength, which is suitable for different ages people, especially for the old and weak, the injured to wall or do some other activities in the swim spa for physical restoration. Two of our arms can drive the water, swing and so on after getting into swim spa, which let our muscle gaining effective exercise. Finally, they have a good consequence for enhancing our health.

During walking in the water, bigger resistance is needed to be conquered. Hence our muscle and visceral organ will enjoy enough exercise. Generally, people walk in the water deep to waist, they walk 1 step/ second and walk 3 to 5 minutes under that frequency, their heart rate will reach 70% to 85% of max heart rate, and their respiratory rate is over twice respiratory rates when they are without doing any activities,knee-join burden is tiny due to water buoyancy, the muscle around the knee-joint and muscle tendon will get enough extension. And limb injured are rare, thus many water activities become one of popular rehabilitation methods among the mild injured. propeller technology make water flow coming into being and the water flow product Von Karman vortices, which Shake our body fat and let our brain wave area steady. AS the same time, they stabilize neurotransmitter for attaining a good therapy effect and accelerating the rehabilitation.

Swimming and athletics


Swimming and athletics

Athletic swimming is a kind of sport based on speeds, which need high technology to reduce resistance to improve swimming impetus, and take fully advantage of our energy for sport. High elbow flexion arm driving water is the one of convincing example which can explain swimming technology important feature.

They display shoulder joint relatively fixe when we swim and the position of shoulder joint more higher.

Compared to other way of driving water, high elbow flexion arm driving way can easily improve the swimming speed.

Driving water frequency and their distance are regarded as one of criterion in the swimming technology. They are three important elements for swimming athlete.

Our newest swim pool adopts laminar flow technology, you will clearly observe athlete's swimming posture which is good for coach's observation and guiding for the athlete.

With adjustable control panel, coach can directly adjust athletes' swimming post, and find athletes' most appropriated connection of driving water frequency and distance, which can effectively improve athletes' score.

Maximum water flow of our new swimming pool reach to 2.3meter/second, which have attained Olympic athlete's training water flow speed.
