A set of ecologically clean toilets for passenger cars
The ecologically clean toilet set (ECT) was created to replace ordinary toilets to improve the quality and comfort of using toilets in trains.
The set is designed to meet the physiological and hygienic needs of personnel and passengers in passenger, service, and technical cars, cars of diesel and electric trains, locomotives,and other types of rail rolling stock, as well as for environmental protection - hygienic storage of household waste before disposal.
Works in the following conditions:
- temperature: from -40С to 60С. At 2С, automatic water discharges from the system.
- humidity: no more than 75%.
- An environmentally friendly toilet set consists of the following main elements:
- toilet unit - 2 pcs.
- a set of a drain tank on the working side - 1 set.
- a set of a non-working side drain tank - 1 set.
- compressed air supply unit - 1 pc.
- power supply unit - 2 pcs.
- a set of display devices - 1 set
- a set of brackets, materials, and standard products for installation - 1 set.
Technical characteristics of the EHT set:

- in standby mode -- 2,0
- in flush mode -- 20,0
Power of the tank heating system, kW, no more than:
- у in summer (temperature over 3⁰С) -- 0,0
- in the winter period -- 1,0
The power of the heating system of the drain system, kW, no more than:
- in summer (temperature over 3⁰С) -- 0,0
- in the winter period -- 1,0
The power of the compressed air supply unit, kW, is no more0,5
- on-board network of the car DC 24 V19...30

Water consumption during flushing (one full cycle), l/cycle~ 0,5
Compressed air consumption for one complete flushing cycle (when the pressure in the system is 5 kg/cm2), l/cycle~ 20
Dilution in the toilet block during flushing, kg/cm2, no less -- 0,6
Working pressure in the toilet block during flushing, kg/cm2, no less -- 0,7
Operating pressure range of compressed air at the inlet in the toilet block, kg/cm -- 24,3...8,0
Working range of water pressure at the entrance to the toilet block, kg/cm -- 20,1…1,5
Operating temperature range:
- drain tankminus 45C…45C
- equipment installed inside the car -- 2⁰C…45C
Toilet equipment provides:
- serving passengers for three days without emptying the storage tank;
- the possibility of emptying the storage tank from both sides of the car;
- flushing fecal waste from the toilet of the toilet unit in no more than two presses of the flush button without splashing water;
- control of the heating system, regulation of the temperature inside the storage tank at an ambient temperature of minus 50 °C;
- control of the presence of water in the water main, control and regulation of pressure in the pneumatic system, control of temperature and filling of the storage tank;
control of electric motors:
- 1. water pump - in automatic and manual mode;
- 2. circulation pump - in automatic and manual mode;
- 3. compressor installation - in automatic mode;
Toilet equipment provides:
- 1. filling the storage tank. Fill levels: 10%, 80%, 95%;
- 2. permission and prohibition of toilet operation at tank filling levels '<95%' and '≥ 95%';
- 3. permission and prohibition of using the toilet in the presence or absence of water;
- 4. permission and prohibition of operation of the toilet in the absence of 220V power supply to the electric motors of the compressor installation;
- 5. permission and prohibition of the operation of the toilet according to the pressure in the main line.
