Ideal for renovations, the Top Onyx system also works with new pools. Robust and flexible, it offers excellent value for money. Its above-ground installation requires no work in the pool and does not reduce swimming space. Located in the stainless steel axle, the engine offers optimal performance while remaining silent. 

The Top Onyx system is based on the Top Quartz with attached protective casing, chosen by the customer.

Used in combination with Covrex® slats, Top Quartz provides the best in terms of safety and energy savings, whether with Covrex® Solar and its exceptional heating properties, or with Covrex® Classic, which offers the best insulation coefficient on the market.

Like all Covrex® drive systems, the Top Onyx is made in Belgium using the best quality of stainless steel.
