The consumption of air in Electro Pneumatic Pressurized Flushing System is 3 liters per flushing operation.

The system would be ready for next use in 7-8 Seconds after each flush.

The Electro Pneumatic Pressurized Flushing System dispenses 1.5 Liter water each time with pressing the Push Button Switch.

The Electro Pneumatic Pressurized Flushing System dispenses water at pressure of 2-3 Kg/cm² each time.

After the pinch valve is closed, compressed air is blown into the Intermediate tank until a pressure of approx. +0.6 bar is reached.

The vacuum pump evacuates the Intermediate tank until the necessary vacuum level of -0.05 to -0.5 bar is reached.

The complete flush cycle takes approximately 25 seconds from pressing the flush button.

The control unit is designed with the PLC/Microcontroller/Microprocessor having IP67 protection from dust.

The intermediate tank (vacuum tank) can handle -80 KPa of working pressure.

The preset pressure guard controls the compressed air supply of the pinch valve with switching point of 300/250 Kpa.

One Pinch valve is installed into the piping between squatting pan and the intermediate tank and one pinch valve is installed between the intermediate tank and the bio-digester.

Due to the design and placement of the flush nozzles, the water consumption of the squatting pan is low, just approx. 0.5-0.7L.

The bowl is equipped with five plastic nozzles that will flush the bowl efficiently.

The electrical requirement for toilet system components is 24V DC.

The water pressure required is 0.2 bar to 1.5 bar with minimum flow rate of 2 Lit/min.

The toilet system requires compressed air supply of 4 to 10 bar pressure.

The weight of the toilet bowl (western commode/Indian pan) is approximately 12.5 Kg.

Bowl of western commode and Indian style toilet pan is made up of SS AISI 316L or better grade with surface finish no.7.

Total peak power requirement per coach for toilet system is 800 watts maximum.

The equipments are so designed to withstand 30% voltage fluctuations.

110V DC only is available in Non-AC coaches for the toilet system.

110 Volt AC/DC power supply is available in all AC LHB coaches.

There is provision of one 75 ltr reservoir in the coach exclusively for toilet system.

A limited quantity of air supply of around 15 lit/min per coach can be made available connected to feed pipe at 6 kg/cm².

For non-AC LHB coaches, a tank of 390 litre capacity is available at the same height of about 2030 mm from toilet floor.

There is one tank of 30 ltr capacity available over each toilet at a height of about 2030 mm from toilet floor in air conditioned coaches.

The water consumption shall be minimum with 0.5 liter (min.) to 0.8 liter (max.) water per flush for 100% cleaning of the commode or pan.

The height from rail level for the Bio-Digester tank is 270 mm.

SS fasteners are used in place of MS on tank covers to prevent corrosion.

A ball valve with handle is provided for operation during emergency for making toilet direct discharge in case of choking.

Poly grass mats are provided for protection of bacteria inside the walls of the Bio-Digester tank.

The Bio-Digester tank has 06 partition walls inside the tank for proper digestion process.

The length of the Bio-Digester tank is 1040 mm, with height of 515 mm and width of 766 mm.

The width of the Bio-Digester tank is 766 mm, with height of 515 mm and length of 1040 mm.

The dimensions of the Bio-Digester tank are: Height: 515 mm, Width: 766 mm, Length: 1040 mm.

The full tank weight of the Bio-Digester tank is 425 Kg, while the empty weight is 120 Kg.

The empty weight of the Bio-Digester tank is 120 Kg, and the full tank weight is 425 Kg.

The working volume of the Bio-Digester tank is 332 litres, while the total volume is 410 litres.

The total volume of the Bio-Digester tank is 410 litres, with a working volume of 332 litres.

The IR-DRDO Small Bio-Digester Tanks for LHB coaches are made of stainless steel with inbuilt C-Type mounting system and partition walls inside the tank.
