Cascade dryer

Simple Principle – Great Effect

With our latest innovation, the patented LAVACascade cascade dryer, we are setting new standards in industrial laundry drying. The focus: maximum energy efficiency, consistent quality and a practical, well-designed drying concept.

Optimized Energy Management with the Cascade Principle

A cascade system consists of two heated dryers followed by a downstream cooling dryer.

The highlight: waste heat from the second dryer is specifically reused in the first dryer. The entire air recirculation is dynamically controlled via inlet pressure and temperature, as is the heat transfer between dryer stages. This keeps the heat exactly where it is needed – inside the process.

Sequential Operation for Maximum Efficiency

The system operates strictly sequentially: a dryer can only be unloaded when the following dryer is empty. This “accumulation principle” prevents heat loss and ensures laundry never cools on the intermediate belt, maintaining high efficiency and consistent product quality.

Energy Recovery Down to the Last Detail

Exhaust air can optionally be routed through a heat exchanger, preheating incoming fresh air. Even the last available kilocalorie is intelligently fed back into the process, maximizing energy utilization.

Three Stages for Maximum Process Reliability

Cascade Stage 01 – Heating Up:
The burner raises the laundry to the target temperature and maintains it, preventing unnecessary cooling and ensuring efficient energy use.

Cascade Stage 02 – Hold Out:
Laundry moves to the second stage at fixed 7-minute intervals, drying to completion without energy losses from restarts or cooling phases.

Cascade Stage 03 – Cool Down:
Laundry is gently aired and cooled for safe further processing.

50% Less Energy – 100% Innovation

Thanks to sophisticated temperature management, heat recovery and an efficient loading system, the LAVACascade uses over 50% less energy compared to conventional drying systems. This not only reduces costs but also makes your operations future-proof – especially important as CO₂ costs rise.

Intelligently Networked with LAVAosLaundry
