Why a closed loop changes operating costs

At the time of purchase, machines are often compared on price. In use, what weighs most is operating cost: cleaning fluid consumption, discharge management, downtime for draining. This is precisely where the closed loop makes the difference.

Open loop or closed loop: the difference

In an open loop, the bath fills with contaminant over the cycles and is then replaced. In a closed loop, the cleaning fluid is continuously filtered and regenerated: it stays usable for longer, which stabilises the process and reduces how often the bath must be drained.

Where the cost shifts

• Consumables: a regenerated bath is renewed less often.
• Discharge: a reduced volume of spent bath limits effluent treatment.
• Availability: fewer drain-downs, so more productive machine time.
• Quality: a bath with stable composition gives consistent cleaning.

A design choice, not an option

A closed loop is not an accessory you add on: it is a machine architecture, designed around filtration and regeneration. That is why it is decided when choosing the equipment.
