The goal of the industrial cleaning system is preservation of the functionality of the machines and systems as well as extension of the service life. Difficult-to-access and hazardous areas which require thorough cleaning at regular intervals are often found in chemical plants. RSP's high-performance suction excavators are ideally suited to these tasks as they extract by suction over long distances. With the installed gas warning and earthing system and a remote control unit in explosion-proof design they comply with the safety requirements for such systems.
