Sub Engine Bus Air Conditioning Overview

The sub engine bus air conditioner is an additional complementary solution for bus air conditioning. It can be used in combination with any engine-driven bus air conditioner. With such a solution, the air conditioning will no longer be limited by whether the bus engine is running or not. In other words, even if the bus is parked, the air conditioning can still be used and the cold air will not stop. Also known as independent bus air conditioner.

This matching solution is designed primarily for high temperature areas. Two main scenarios are considered. One is when the bus stops frequently; the other is where a single engine is not sufficient to keep the bus running and where high cooling capacity is required at the same time.

We have also designed it for vibration damping and protection against high temperatures.
