There are some optional functions to enhance the linen chute system.
The linen chute intake / loading doors can be programmatically controlled by
electrical interlocking system, which only allows one door to open and
remaining doors can not be opened and therefore
eliminates the danger to the operator / cleaner loading the soiled linen at lower
floor if there is no this system in place. And it also prevents contamination risks
of the soiled linen from other floor.
The system has a control panel each
floor with the linen loading door. A main control box is located
near the discharge, which shows status of the system, such as normal or
faulty at which floor, etc., which can be connected to the building
control system.
Manual control is located at the main control boxed to shut all doors
for maintenance purpose.
In case of power failure or system breakdown,
all the doors can be operated as normal access doors.
Building fire protection / alarm system can be optionally linked to the interlock system then the former signal would trigger the system to shut all the doors in case of fire as precaution measure.
Sprinkler heads can be provided at alternate floors as an extra safety measures.
Top hinged fire rated stainless steel discharge door energised with fisible link which would break and shut the door automatically in the event of fire or when the temperature exceeds 75℃. it is part of horizontal discharge which is supported by a pedestal designed to absorb the impact of soiled linen dropping against the chute.
Earth bonding system provides not more than 10 Ohms resistance between the linen chute and building earthing system.
Sound damping / insulation can be chosen by factory applied coating for noise reduction.
Other options are fire damper at roof slab, fire stop at each floor, flushing spray head with or without disinfecting and sanitising unit, smoke detector, heat detector, key alike or master key for mechanical locks.
And stainless steel / aluminium linen cart / trolley can be made according the requirement.
