The Waterlogic WL7 Firewall™ (WL7 FW) is an advanced water purification system designed for busy workplaces, offering a range of water options and high-tech features in a robust and reliable machine.
Function Description:
The WL7 FW dispenses a large volume of ice-cold and sparkling water, in addition to ambient, hot, and extra-hot water options. It utilizes Waterlogic's patented Firewall™ technology for purification, ensuring 99.9999% purified water at the point of dispense through a highly effective UV antimicrobial system. The machine also incorporates BioCote® antimicrobial protection on key surfaces, which inhibits microbial growth, reduces odors, prevents degradation of surfaces, and minimizes cross-contamination. Best-in-class filtration is provided by Waterlogic filters. The new Ice Bath cooling technology delivers high volumes of consistently cold water, making it suitable for demanding environments. The system is designed for indoor use only and is not intended for treating microbiologically unsafe or contaminated water.
