GARBAGE CHUTE

Ventilation

Trash chute vent and exhaust fan play a major role in inhibiting unwanted smell in your building. Kapella recommends a minimum of 10ACH in the chute and applies its system worldwide accordingly. NFPA 82 specifies that trash chutes should be ventilated. In addtion ASHRAE 62.1 2007 standard specifies minimum minimum exhaust rate for trash rooms as minimum 1cfm/ft2. The vent unit is shaped from stainless steel parts such as weather proof cap, insect screen and vent duct.

Brush Cleaning System

The cleaning system consists of a cylindrical housing, with two bands of stiff nylon brushes, firmly attached, a geared electric motor, cable, stabilizing weight, flushing head spray and the manufacturers standard electric logic control installed to ensure efficient cleaning of the internal surfaces of the chute. Brush unit often operates together with the sanitizing unit and the flushing system for proper cleaning of the chutes. Trash chutes need to be cleaned periodically by the brush cleaning system while duct cleaning should be performed every two to five years. The avoidance of necessary maintenance may result in serious health effects such as cold, allergies and watery eyes.

Keyed Access/Maintenance Door

The inspection Access Door is situated on the top floor, kept above the hopper door. The keyed handle Fire Rated Door is shaped from Stainless Steel leaf.

Self-latching keyed handle enables easy operation. Available with 450x450mm clear opening and 600x600mm clear opening. The door is used for refilling and inspection of the components of the cleaning system.

Sprinklers for Fire Security and Flushing System

A. Fire Security

The fire sprinklers are mandatory for the security of the systems. Fire sprinklers are provided at each floor and a fire cut off door at the bottom of the chute for fire security. The chute system can interconnect with the BMS fire alarm system that locks the system in the case of fire.

B. Flushing System

A solenoid valve will determine (along with the Disinfectant & Sanitizing Unit) the water flow through all cleaning sprinklers (at each floor) to wash the garbage chute along with the disinfectant liquid located at top floor.The hopper doors are closed during cleaning process.   The disinfectant injects into the water comes in cycle through Solenoid, Riser and Sprinkler head, then water stop automatically and release the door locks.

Chute Support Frames

Hot Dip Galvanized Chute Support Frames are fixed around to chute and bolted to SSL and to wall by 4 Nos Rawl plugs.  The wing is shaped from 5mm Mild Steel and welded to 50x50x5mm angle bars. The interior of the rings are covered with 3mm anti vibration rubber pad as a sound isolator and protects the chute from corrosion. The frames are fixed to slab at each floor.

Fire Rated Intelocking Doors

The standards are improved with a solid, mono-block stainless steel surface with its specially designed gas pistons enabling easier and safer operation. The electromagnetic interlocking with led indicator lamps enables one user at a time and automatically locks all doors during the maintenance.Fire Rated doors outstands not only with its design and operational use, but also its durability since the complete body of the door is shaped from 1.5mm Stainless Steel Sheet, including its latch, indicator lamps and handle are made out of stainless steel.

Clamp Rings

Stainless Steel clamp rings are fixed to the exterior of the chute the cover bell-mouth tubes, ,in order to make chutes smoke proof.

Chute Duct

Chute Duct extends from the garbage collection room to the top floor where the highest intake is located., The tubes are continuously TIG welded which ensures watertight system without any bolts, rivets or other projections inside the chute.

Chute Intake

Chute intakes are designed to fix the hopper doors for proper disposal of the trash bags. The intake sections are continuously welded, rectified inside and sealed externally with mastic to be free from obstructions.

Offset

The stainless steel sheets are continuously welded chute offset is a 45° angled discharge unit reinforced and separately supported at the area of impact.

Bi-Sorter/Tri-sorter

Electro-Hydraulic motorized systems for distributing materials from one chute into designed containers operated by the push button controls at intake doors.

Fire Shutter Door

Galvanized or stainless steel fire shutter doors are required to provide 1 1/2h fire rated assemblies held open by fusible link for automatic closing with heat rising above 72° C.

Control Panel

The master control panel is located at the garbage collection room and includes necessary switches, relays, lights for the operation of the chute accessories such as automatic sanitizing system, exhaust fan, brushing unit and interlocking doors. The control panel is interconnected with the fire and smoke alarm system in order to lock the chute in case of fire.

HDG/HDPE Trolleys

The Hot Dip Galvanized Wheelie Trolleys are welded with inert-gas technology. There lifting arms and carrying rollers are manufactured in compliance with EN standards.
