Drainbox is ESPA’s advanced, specific solution for removing sewage, grey or rain water from all environments – household or professional, rural or urban – with complex or unfavourable drainage conditions.
Drainbox collects, accumulates, treats and delivers wastewater to the sewerage system, as well as offering truly exceptional advantages in terms of versatility, installation and performance. Drainbox provides simple, highly efficient drainage technology allowing each pumping kit to be customised with the pump that is best suited for the function and performance required.
Drainbox is presented in an innovative tank whose design includes many technical advantages that add performance in order to customise each installation. It includes the choice of inlet and outlet pipes, the choice of ventilation pipes, the choice of emergency drainage system and the choice of check valve. The tank is made from 6-mm-thick high-density polyethylene with the bottom designed to avoid sedimentation spaces.
Pumps liquids at temperatures of up to 40 ºC.
It includes electric pumps from ESPA’s standard series and CTF-TOP control panels for optimum operation of the double pump unit. It also has an anti-blockage protection system with programmable preventive start-ups and protection against dry operation by phi cosine or current surge.
