Networked HI-FOG® Electric Pump Units Offer Increased Scalability for Fire Protection
5 December 2017

HELSINKI, Finland, December 5th, 2017— Marioff announced today a single HI-FOG® fire protection system can include up to eight HI-FOG® Electric Pump Units (EPUs) in a single water distribution system. By networking multiple units together, it enables higher system capacity and a more flexible system design allowing for protection of larger areas from fire. Marioff, a leading developer of water mist fire protection technology, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).

“Multiple unit connection is a natural next step with the new software-controlled HI-FOG® Electric Pump Unit. The networking design is robust and well-tested for multiple configurations,” said Markku Vuorisalo, director of engineering, Marioff Corporation Oy.

Networking of HI-FOG® Electric Pump Units promotes system redundancy in compliance with the International Maritime Organization’s Safe Return to Port rule. The connected units also offer reliable two-way communication with self-diagnostics, and optimized maintenance and service operations. The HI-FOG® system status can be monitored at any individual user panel and the communication network enables simplified changeover controls between the connected HI-FOG®EPUs.

HI-FOG® EPU networking will be available for land and marine customers beginning in December. For more information, visit
