After 6 to 12 years of use, the air-conditioning components will be damaged and consumed to varying degrees, resulting in a decline in the cooling/heating effect of the air-conditioning unit, and the inability to meet customer needs. We recommend replacement solutions. Heshan provides the dismantling of the old machines and matching the corresponding new elevator air conditioners. If the original elevator accompanying cable can continue to be used, there is no need to replace it, only the main engine and accessories can be replaced.
The non-remote-controlled elevator air conditioners installed in recent years without the Internet of Things function can also be upgraded to intelligent cloud communication-controlled remote elevator air conditioners. The main body of the air conditioner does not need to be replaced, only the control board needs to be replaced, and a communication gateway and a few accessories can be added. 

In order to improve the ride comfort of the elevator car, the existing elevators do not have elevator air conditioners. The Heshan elevator air conditioner series is suitable for all types of elevators, and can also be customized for non-standard processing. Heshan Company provides full supporting installation services. In the era of Internet of Everything, it is recommended to install cloud communication with Internet of Things control function to control remote elevator air conditioners.

After using for a certain period of time, the effect of the whole machine may not meet the needs of customers. We recommend replacement plans. Heshan provides the dismantling of the old machine and matching the corresponding new car air purifier.

In order to provide a healthier elevator environment, the Heshan car air purifier series is suitable for all types of elevators, and can also be customized for non-standard processing, and Heshan Company provides full supporting installation services.

After using for a certain period of time, the effect of the whole machine may not meet the needs of customers. We recommend replacement plans. Heshan provides the dismantling of the old machine and matching the corresponding new shaft cooling fan.

For some elevators with poor heat dissipation conditions in the machine room, such as sightseeing elevators, elevators installed, and elevators without machine rooms, the phenomenon of excessively high temperature at the top of the hoistway (or machine room) is more likely to occur in summer, which affects the safe operation of the elevator. The intelligent hoistway cooling equipment developed by our company uses mechanical ventilation to reduce the temperature of the top of the hoistway (or machine room), which can effectively improve the elevator environment and ensure the safe operation of the elevator. It can also be customized for non-standard processing. Heshan Company Provide full support installation services.

After a certain number of years of use, the parts will be damaged and consumed to varying degrees, resulting in a decrease in the effect or other failures, which cannot meet the needs of customers, etc., we recommend a replacement plan.

As the temperature increases, the viscosity of the oil decreases, the oil film of the part to be lubricated is destroyed, and the oil leakage increases, which directly affects the leveling accuracy and comfort of the elevator. The fit and the settling amount of the car affect the heat dissipation effect of the oil-immersed motor in the pump station. When the oil temperature is too high, it may even trigger the thermal protection action of the hydraulic system and lead to the occurrence of elevator shutdown accidents. Heshan hydraulic ladder oil cooler is professionally developed to solve this problem, and Heshan company provides full supporting installation services.
