In 2019, we established a strategic partnership with TATA Motors, a world-renowned automobile manufacturer. TKT HVAC established a factory in India and was deeply involved in the customization and optimization of its electric bus air conditioning system. With accurate insights into India’s operating environment, energy consumption requirements and durability, we created a customized bus air conditioning solution that combines high performance and long life. This solution passed the rigorous testing of TATA’s technical team. The first batch ordered 45 units of 9M electric bus air conditioners at one time, and then steadily purchased them every year. TATA Motors’ senior manager praised: “It far exceeded expectations in durability and core performance, and is a trustworthy bus air conditioning partner!” Click here for details.

1. Global Quality Certification: TKT was established in 1998 and has more than 20 years of experience. We have ISO9001, CE, EMC certifications, and more than 100 patented technologies.
2. Excellent Comfort: TKT has rich experience in OEM development. Powerful refrigeration and air filtration systems ensure that the bus climate reaches the ideal comfort level.
3. Proven Reliability: Our electric bus air conditioner uses high-quality compressors (Japan Sanyo, etc.) and rugged components. For example, Sanyo compressors are proven and rated for around 80,000 hours of service life. If used 10 hours a day, the life span is more than 20 years.
4. Efficient and Environmentally Friendly: Our electric bus AC systems are powered by electricity and achieve “zero emissions”. Secondly, the refrigerants are all environmentally friendly refrigerants. They do not pollute the environment.
1. Energy-saving and high efficiency: TKT uses advanced compressors and control systems to provide precise temperature control. Optimize the climate with minimal energy consumption and help extend the bus’s mileage.
2. Comfort at any time: The electric bus air conditioner is not affected by whether the vehicle is running or not, and the cooling mode can be turned on at any time. Ensure that passengers remain comfortable in stop-and-go urban traffic.
3. Quiet operation: The electric drive method and the use of silent fans make the overall noise very low, which can provide passengers with a better riding experience.
4. Zero emissions: The electric bus air conditioner runs on the battery of the electric bus, so there is no additional fuel combustion or exhaust emissions. Support global environmental protection.
TKT electric bus HVAC system has a strict quality inspection process. Such as EMC electromagnetic test, piping air tightness test, drenching test, vibration test, finished product test and so on. This is all in order for you to get reliable bus air conditioners. (Click here to view Bus Rooftop Air Conditioner quality Inspection details)

During this period, you need to communicate with our experts to confirm the root cause of the problem. For extended warranty and other issues, please contact us for detailed communication.
An electric bus air conditioner is a temperature control system designed specifically for electric buses. It does not rely on the engine of a traditional fuel bus, but is driven by a high-voltage power pack to achieve cooling, heating and air circulation functions.
Drive mode: The power battery pack drives the permanent magnet synchronous motor through high voltage electricity, thereby driving the scroll compressor to operate, without the need for engine belt drive.
Energy efficiency optimization: The speed can be adjusted using variable frequency technology to adapt to different load requirements and improve energy efficiency.
Core components: compressor, condenser, evaporator, expansion valve, dry filter, etc.
Working principle: The compressor compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gas, which becomes liquid after heat dissipation through the condenser. After that, it enters the evaporator through the expansion valve throttling to absorb heat, and finally sends cold air through the blower. Circulation work to achieve heat transfer in the bus. The operating principle is basically the same as that of traditional bus air conditioners.
A. PTC electric heating: Directly heat the air or coolant through the electric thermistor, with a simple structure but high energy consumption.
B. Heat pump technology: Switch the refrigerant flow direction through a four-way reversing valve, use ambient heat for heating, and have significant energy-saving effects, but the structure is complex and the cost is high.
Daily maintenance is mainly based on observation, cleaning, and basic inspection. If any abnormality is found, deal with it in time to avoid small problems from turning into major failures.
1. Observe the operating status: whether the start and stop are normal, and whether there is a fault code. Observe whether there are obvious abnormal sounds and vibrations during operation.
2. Clean the condenser fins: Check whether there is any blockage, and use a high-pressure air gun to blow it clean from the back.
3. Check the pipes and joints: Observe whether the refrigerant pipes are worn or cracked, and whether the joints are loose or leaking oil.
4. Check the drain hole: Check whether the drain hole at the bottom of the evaporator is blocked. It is recommended to use a thin wire or other methods to dredge and clean up the debris.
1. The vehicle high-voltage power supply must be disconnected before maintenance, and wait for more than 5 minutes for the capacitor to discharge. In addition, tools such as insulating gloves must be used.
2. Although R407C is an environmentally friendly refrigerant, direct inhalation will still cause safety issues, so it needs to be operated in a well-ventilated area;
3. The maintenance of electric bus air conditioning involves both electrical and refrigeration areas, and it is recommended that it be operated by trained professionals.
Usually, it is R407C. R407C is an environmentally friendly refrigerant with a large cooling capacity per unit volume. It has a better cooling capacity per unit volume than R134A, and is more environmentally friendly than R22 and will not damage the ozone layer.
