Advanced Electronically Controlled Air Dryer for Zhongtong & King
Long Buses | PN: 3511-00062
Product Description
Ensure the superior performance and unwavering safety of your
Zhongtong and King Long bus fleets with the 3511-00062 Electronically Controlled Air Dryer, a premium component manufactured and supplied by Nanjing Dingguan Auto Parts Co., Ltd.
This unit serves as the cornerstone of your vehicle’s pneumatic
system reliability. Meticulously engineered as both an air
condenser and an oil-water separator, its primary mission is to act
as a powerful defense against contaminants. It aggressively removes
harmful moisture, oil aerosols, and solid particulates from the
compressed air before they can enter the system. By delivering a
consistent supply of clean, dry air, it prevents internal
corrosion, blockages, and the freezing of air lines in cold
climates, thereby protecting vital components such as air brakes,
suspension controls, and transmission systems from premature
failure and costly damage.
What sets the 3511-00062 apart is its advanced electronic control
system. Unlike conventional, time-based units, this intelligent
dryer monitors air system conditions to optimize the desiccant
regeneration (purge) cycle. This smart operation significantly
reduces unnecessary purge air consumption, saving engine power and
fuel while extending the service life of the internal desiccant
cartridge. The result is superior efficiency, enhanced reliability,
and a lower total cost of ownership.
As a direct-fit, OEM-quality replacement for Zhongtong and King
Long buses, this air dryer guarantees seamless integration and
straightforward installation. By choosing Nanjing Dingguan, you are
investing in your fleet’s longevity, operational uptime, and, most
importantly, its safety.
