Paddlewheel History: The birth of a brilliant idea

In 1986 fiberglass pioneer Everett Pearson bought the SwimEx paddlewheel patents from an MIT hydrodynamist and research team. Originally recognized for founding Pearson Yachts and bringing the first production sailboats to market, this gifted entrepreneur combined 30 years of design experience to create the first fiberglass swim spa. Through Pearson’s brilliant ingenuity and vision SwimEx became the leader in aquatic exercise and therapy for athletic training rooms, hospitals, physical therapy clinics, health clubs, senior communities, and private homes.

SwimEx is still owned and operated by the Pearson family.

Paddlewheel Power: Ultimate Performance

SwimEx Exercise Therapy Pool

SwimEx is the only company in the world to offer paddlewheel water current technology. This superior current offers the smoothest yet most powerful water current in the world.

Positioned in the back of the pool, the 99-speed paddlewheel pulls water through a rear grate, pushes it under the pool floor, and out a front grille. The water current spans the full width of the pool, creating a “wall of water” that runs as deep as 30” (76 cm).

The SwimEx paddlewheel pool is the only pool on the market that circulates up to 25,000 gallons of water per minute generating a river-like current.

Both competitive and recreational swimmers will achieve a superior aquatic swimming and exercise experience. If you love to swim, there is no other current as effective as the paddlewheel.  If you want to exercise or need aquatic therapy, the SwimEx S and T series paddlewheel models are the ultimate aquatic machine.

Paddlewheel Current Benefits

With 99 speeds, the paddlewheel current will challenge the most advanced swimmer or athlete, yet it is gentle enough to meet the therapeutic requirements of any level patient.  Air control buttons mounted on the front of the pool easily adjust water speeds to accommodate any ability level. Improve balance, run, swim, achieve full-body workouts – it’s all possible.

The consistent water flow and different speed options make it easy to accurately monitor progress from one session to the next.  The SwimEx EDGE touchscreen monitor lets you program workouts, swim sessions, and treadmill time.

The pool-width flow means you can be anywhere in the pool and still benefit from the current. Swim from one side of the pool to the other. Workouts and therapy protocols can include upper body exercises with no additional pool equipment. Enjoy a smooth swimming experience or safely target specific muscles and joints.  The superiority of the paddlewheel current delivers a better workout, more effective aquatic therapy, and consistent resistance for intensive workouts or gentle of therapy protocols.


SwimEx Pool Construction

Why install a full-sized pool when you can get everything you need from this highly efficient fitness and therapy pool? SwimEx pools pack a powerful punch in as little as 200-square feet of space and fit virtually anywhere.  Using a state-of-the-art fiberglass technique similar to the construction of high performance luxury yachts and aircraft, SwimEx pools range in size from 7’6″ wide to 11’5″ wide (2.29 m to 3.47 m) and 13’6″ long to 18’4″ long (4.11 m to 5.59 m). Extensions are also available in 2′ (61 cm) increments. Plunge pools come in small, medium, large, extra large, or custom-sized up to 45′ long.   They are built with 1/8” (.31 cm) fiberglass on each side of a 3/4” (1.9 cm) balsa wood core to create an insulated “sandwich” of strength.  Layers of fiberglass, resin, and Gelcoat enclose the balsa wood for an indestructible shell.

Fiberglass Benefits:

  • Efficiently maintains water temperature
  • No liners to replace
  • All interior walking areas feature a non-slip surface for safe movement
  • Solid shell means all pools are freestanding and self-supporting, allowing for indoor, outdoor, above ground, or in-ground installations

Gelcoat Surface

Never worry about tearing or replacing a vinyl liner. This smooth surface doesn’t need replacing and acts as a barrier against moisture absorption and algae growth. It cleans quickly, is extremely easy to maintain, and has non-slip surfaces on all interior walking/workout stations for safe movement.


Balsa Wood Core

Between the layers of fiberglass, SwimEx pools have a strong balsa wood core for superior shell strength. Pools are both free-standing and self-supporting, and this insulated layer efficiently helps maintain temperatures.
