Solvent spillage tank
All “CE”-compliant ILSA machines have a “solvent spillage tank” to contain spillage. These tanks are designed to withstand the forces transmitted by the machine. The tank bottom is raised to allow for natural ventilation and prevent moisture build-up, which might eventually lead to corrosion. The design accommodates the need to inspect the bottom of the tank to ensure that it remains tightly sealed over time.
This system is available in a standard and an industrial version. Both versions effectively reduce solvent content in distillation residue. This is achieved by circulating air through the distiller to remove part of the solvent left. The solvent is then condensed and recovered through a suitable circuit.
This sensor determines whether solvent remains clear during washing and alerts the operator when colour loss is suspected. The operation threshold is adjustable; once reached, the operator may choose to start an “anti-bleeding” programme to prevent tank and filter contamination.
Solvent cooler The solvent cooler enables the operator to control solvent temperature, i.e. keep it from overheating, and thus prevents damage to garments. Thanks to this device, special programmes can be created to wash especially delicate fabric or leather garments at any time during the day using adequately cooled solvent.
Water Collection Tank
All “CE”-compliant ILSA machines are equipped with a ”water collection tank”. This is an additional separator that receives water from the main separator. The water collection tank comes with a level control feature and sight glass. The level control alerts the operator when water reaches the maximum level, whereas the sight glass is used to check whether perchloroethylene is present. The tank is suitably sized to hold the maximum amount of waste water which is expected to be collected during one day under normal operating conditions; this means it needs to be drained only once a day, resulting in improved efficiency of the water/solvent separation process.
This system automatically captures any residue released from the load into the air stream. Residue is conveyed into a suitable container at the bottom of the cyclone. At the air duct inlet end, particulate matter is sucked into another duct and conveyed into the cyclone, which separates particulate from the air stream. Filtered air is recirculated to the machine and clogging of the air filter is prevented. After the drying cycle, the container can be emptied with no risk of harmful emissions.
This device allows the distiller to be cleaned in full safety with no need to open the door, preventing the release of harmful emissions. The bottom of the distiller is cleaned by a mobile scraper that is handled by the operator, and any residue is automatically pumped at low pressure to a suitable external container.
