Technology Shafts OXY

Hydrolysis + Saltwater electrolysis including pH regulation and sand filtration system

All components are inconspicuously hidden in the technical pit, while being easily accessible and located in close proximity to the swimming pool - thereby eliminating friction and heat losses. The technical pit is already prepared for the connection of a heater/pool heat pump.

Details technical shaft HydroTec | LowSalt:

  • Oxilife pool water treatment system with pH regulation, including salt
  • FSP-500 pool sand filtration system, including sand
  • Power distribution unit (technically already connected)
  • Integrated bypass for connecting a pool heat pump
  • Includes filter sand and pool salt
  • Connection: 230V
  • Inner diameter: 150cm
  • Outer diameter: 166cm
  • Depth: 120cm
  • Material: Polypropylene

Pool salt water disinfection Oxilife, including hydrolysis, pH regulation and salt.

In addition to electrolysis, the Oxilife system also utilizes hydrolysis. During hydrolysis, water molecules are split, resulting in the formation of oxidants that work more effectively than traditional chlorine to quickly disinfect pool water. Thanks to this combined disinfection method, the Oxilife system requires only 1.5 kg of salt per cubic meter of water (usually only once per year, as salt does not evaporate). The system also includes a self-cleaning cell to ensure optimal performance. The pool saltwater electrolysis and hydrolysis provide fully automatic disinfection and sanitation of your pool.

  • Crystal clear water
  • Very low operating costs
  • Fully automatic pH regulation
  • Self-cleaning cell
  • Only 5% of the salt content of seawater is sufficient (barely noticeable)
  • Stronger disinfection than chlorine
  • Effective disinfection at a minimal salt concentration

Pool sand filter system FSP-500 including sand

The Pool sand filter complete system FSP-500 is equipped with a base plate on which the filter housing made of polypropylene is located, which is equipped with a 6-way valve with a pressure gauge and glued connection fitting ø50 mm. The circulation pump including additional hair filter with a capacity of 9 m³/h is also placed on the base plate, which is connected to the filter housing via a flexible hose. The filter uses filter sand (recommended grain size 0.6 - 1.2mm) to capture impurities from the pool water. The filter housing is filled with filter sand and acts as a dirt collector. When the valve is in the "Filter" position, the contaminated pool water is automatically sucked in through a hose system and pushed into the control valve with patented filter, from where it is transported to the upper part of the filter housing. The water is then pushed through the sand, which removes it from fine impurities, and discharged into the lower part of the housing. Via the control valve, the water is returned to the pool through hoses. The entire process is continuous, automatic and ensures complete filtration of the swimming pool water. After a certain period of operation (4-8 weeks), dirt deposits in the filter housing and lead to a deterioration in water flow through the sand and a decrease in flow through the filter unit (recognizable by an increase in pressure in the pressure gauge). This means it's time to clean the filter. To do this, simply put the operating lever of the 6-way valve in the "Rinse" position. The water flow is automatically reversed, so that the water flows from the bottom up through the filter sand and flushes the settled impurities into the drain line. Once the filter is flushed, set the valve lever to "Pre-filter" and turn on the pump for half to one minute; then the valve lever is brought back to the "Filter" position so that normal filter operation resumes.
