Munters specialist air treatment team, designed, supplied and installed the energy efficient Dry Room with Munters high efficiency MDU system with innovative heat recovery design at the heart of the system.

A constant -45°C dewpoint provides a stable environment, which is critical for keeping the electrolytes as dry as possible while producing and testing lithium pouch cells. Any moisture ingress at electrolyte filling can be detrimental to battery performance.

Conditions are maintained using Munters MDU system located next to the dry room, from here all moisture levels are monitored using an integrated Siemens control system. Munters MDU2000 with a built in high efficiency energy recovery design has
The 9m x 5m Dry Room is just one part of the Pilot Line, accommodating up to 6 personnel, with a relative humidity of less than 1% and a continuous dewpoint of -45°C.

The Dry Room contains all the pouch cell making equipment where moisture sensitivity on cell materials becomes an issue after drying of electrodes such as:

• Electrode Drying and Cropping
• Stacking into cell stack
• Insertion into pouch
• Electrolyte filling
