Since the foundation in 1920 F.lli Razeto & Casareto designs and makes exclusive marine locks, doors’ and cabinets’ accessories, with special consideration to designers’ and ship owners’ needs; now as never before, keeping safety of guests, staff and employees of Ships a priority matter of research and product development.

The italian company once again introduces to the market, in cooperation with the Italian Naval Register, two projects designed to increase safety onboard:

OSSH Network, smart access integrated system with luminous handles for fire doors and cabin doors and Antimicrobial Handles.

Both projects feature unprecedented applications that lend themselves not only to use on board naval units but also on yachts, platforms and terminals.

OSSH Network is an integrated system of luminous handles for doors which light up to be detected in critical conditions and provide information such as emergency indicating escape routes with the color of light.

OSSH NERTWORK interacts with external systems (FDS, ESD, SMS, SMCS)  via communication protocols such as modbus. The management electronics are placed in junction boxes hidden in in the ceiling, wired with a BUS485 system that carries a network signal throughout the vessel and power supply to the handle through the lock catch.

The procedure of checking the operation of the fire doors before the ship’s departure is made faster by the presence of the luminous handles: at a glance the crew can see if the doors are correctly closed or not

The system is provided in kits to be simply installed, even in the case of retrofitting, as an unambiguous safety means of hazard communication via BUS485.

Each kit is composed of a junction box containing the controller; door lock and striker, equipped with the patented power and data transfer device; a pair of luminous handles featuring 40RGB LED’s each.

F.lli Razeto e Casareto is leading manufacturer of locks for marine fire doors and OSSH NERTWORK   kits do not vary in size or shape from the standard ones. This makes retrofitting quite easy; by simply equipping fire doors with the OSSH KIT, ship owners can improve safety onboard their vessels.

OSSH NERTWORK   improves safety and security:

  • green light to address passengers, guests and employees to escape routes (fire -panic -gas) and save their lives
  • red light to prevent from opening the fire door during a fire.
  • door handles are visible during black out to highlight escape routes.
  • in an anti-intrusion plans door handles indicate if a door needs to be locked closed and if it is actually locked.
  • in an evacuation plan the color of the handle indicates if an area has already been checked.
  • easy to fit, the cable free power and data transfer system allows economical installation on new constructions or retrofit to lower risk factor and running costs.

OSSH NERTWORK is being certified by RINA (Italian Naval Registry) to obtain the Technology Qualification Certificate

ANTIMICROBIAL HANDLES Is a collection of door handles, which feature ESI antimicrobial system, a diffusion chemical-free permanent treatment made out of an innovative complex metallic cluster that continually emits silver Ag+ and other metal cluster complex ions. This emission of ions exerts an antimicrobial action on objects and in the environment, disinfecting continuously with complete safety and silence. The antimicrobial action requires no source of power and is guaranteed 24/7 for over 10 years.

Door handles thus excite  a continuous antimicrobial action, cannot be contaminated  by  fungi , bacteria and viruses and exert an active action in the environment and on  hands which are sanitized by the touch The  effectiveness against  Corona Virus has  been found  with laboratory tests by  the Virology Lab of the University of Modena e Reggio , as well as by the Universities of Genova and Siena, Italy and certified  by the Italian naval register, Rina, in compliance with its  additional note  of Classe Biosafe Ship with reference to  surfaces with high utilization rate.

ANTIMICROBIAL HANDLES improve Safety: handles surfaces cannot be contaminated by bacteria, fungi, viruses; the sterilizing action is extended to the environment even sanitizing the hand.

ANTIMICROBIAL HANDLES represent a system of mitigation of spread risk for pathogenic agents; a benefit to shipowners, passengers and crew.

The award-winning company has been designing exclusive door handles for both nautical and shore-use in Italy since 1920.
