Spargers

Spargers or air bubbling systems are designed for competitive diving practice. It is a piece of equipment that releases air directly underneath the path of the diver’s travel that will soften their impact with the surface of the water. It is used when divers are attempting new dives.

The system should be set up for remote activation on the pool deck.  At this time, the Aquair system through Myrtha does not have the capability of remote control operation AND changing sparger lines therefore a control panel will need to be installed out on the pool deck or in pool manager / coach’s office.  Electrical requirements will need to be coordinated with project engineer for locating the control panel.

The air supply system has two major components:

  • A large vertical compressed tank is located in the mechanical room with solenoids that activate the sparger and release the air.
  • A rotary screw type 60 to 75 CFM air compressor supplies the vertical compressed air tank.  A 75 CFM compressor is required for systems that include more than 2 diffuser locations.  The compressor must be equipped with an internal dryer unit.

Due to the excessive noise of the compressor, it is recommended that it         be located within an enclosed space away from the general population.

A large compressed tank is located in the mechanical room with solenoids that activate the sparger and release the air.  It takes a while to recharge and be used again.  Due to the excessive noise of the compressor tank, it is recommended that it be located within an enclosed space away from the general population.

The sparger system (Pulsair) at Tennessee was installed in the mechanical room on the opposite side of the natatorium from the diving well (approximately 250 feet to 300 feet away).  A good signal was very difficult to get with this set-up.  As a solution, the sparger antenna was routed through some existing conduit for a clock into the natatorium and the signal is much better.  The designer should pay close attention to the location of the sparger system and antenna during design.

If the sparger mechanical equipment is below water level check valves are required.

Confirm coalescing air filter with auto drain that removes water vapor and oil filter has been installed on the discharge side of the compressor and prior to the solenoid valves.

A caulk joint and tile are required around the sparger diffusers in the pool floor.

Check valves are required for all spargers.

Confirm coalescing air filter with auto drain that removes water vapor and oil filter has been installed on the discharge side of the compressor and prior to the solenoid valves.

Specifying a sparger is a programming decision, but it should be included on all facilities where there is platform diving.  There are only two Counsilman-Hunsaker approved manufacturers of spargers in the U.S. ADG and Aquair.

Cost for a sparger will start around $70,000 to $80,000.
