VDH movable floors

The VDH movable floor is of the ‘floating floor’ type and consists of modular RVS Aisi 316 L/Ti floating modules. The individual modules measure 2000x1000mm. This makes them easy to operate and means you don’t have to make large adjustments during the installation of the floor. Unlike traditional movable floors, the VDH movable floor does not require a structural basement around the basin. It also does not require any intervention on the structural pool walls toaccommodate cylinders. This means that the entire space around the basin remains empty. This, in combination with a very limited built-in height, makes the VDH movable floor suitable for use in new projects as well as existing pools.

The floating modules are attached and the topside is fitted with white, chlorine-resistant HDPE floor panels with a non-skid finish. Motor units (24V DC 1,1 KW nominal 25 Amp), fitted with a gearbox and stainless steel underwater casing, are installed in four of the stainless steel modules in the floor. The structural basin floor is fitted with four stainless steel barrels that are attached to the motor units with stainless steel cables. The cables pull the floor to the desired water depth.

The operation of the VDH movable floor relies on PLC technology. The operating installation consists of a switch-box 4,4 kW, 380 V AC, 4 x gear to 24 V DC 25 Amp.; PLC by Omron including program (specific circumstances to be discussed); colour TS by Omron with operation software (lay-out and other requirements such as pre-set depths to be discussed) and a compressor at 230V with pressure reducing valve. Furthermore, the system features a water depth display with an acoustic signal and a flashing “do not dive” pictogram during floor movement.

Benefits of the VDH movable floors:

-No extra space needed below the basin to accommodate hydraulic lifting cylinders
-No risk of leakage from cylinders
-No oil leakage from cylinders
-No cables across the structural basin floor, which makes cleaning easier
-No large accommodations or passages necessary during the installation of the floor
-No chlorine-using depositories below polyester floor elements
-Easy maintenance from the topside of the floor
-Easy to assemble in both existing pools and new structures
-Variable measurements possible
-Floor panels can be easily replaced, if necessary
-Floor panels are finished with anti-skid surface
-Maintenance and service can be analysed using a central modem
