In Focus: Haldex General Service Kit

One of the systems that could be neglected despite its importance to the truck's safety and performance is the air brake system. This shouldn't be the case with your fleet. To minimize downtime and increase your business's profitability, it is essential to provide all your trucks, commercial vehicles, and buses with the necessary preventive maintenance. It is also crucial to have your truck's critical systems regularly checked by a pro. For example, keeping up with Haldex brake and air suspension solutions ensures your braking and suspension components stay reliable.

When it comes to maintaining your truck's air dryer, no other brand could help you better than Haldex. You can depend on the Haldex general service kit to make the maintenance and servicing of your Pure Air Plus™ air dryer more straightforward and efficient.

Haldex: Company Overview

Haldex envisions a world with safer vehicles. This vision propels the company into what it is today—a leading provider of innovative brake solutions to the global commercial vehicle market, with a primary focus on enhancing the vehicle's safety, dynamics, durability, and environmental impact. This company also takes pride in its unmatched expertise in air suspension systems for trucks, trailers, and other heavy vehicles.

Since its founding in Landskrona in 1887, Haldex has been known for pioneering research and development projects that paved the way for groundbreaking technological vehicle solutions. Currently, the brand's development team focuses on the safety and potential of autonomous, electrified, and connected heavy vehicles.

Haldex operates in more than 19 countries worldwide. Its main customers are some of the world's largest manufacturing giants in Europe, North America, and Asia, as well as the trucking and bus industries in these regions. For the aftermarket, Haldex provides spare parts and services to a wide range of distributors, workshops, and logistics companies.

The company's innovative product portfolio comprises two major product categories: The Foundation Brake, which includes all brake products, and the Air Controls, which consist of solutions that improve the brake system's driving dynamics and safety. It also offers a wide array of maintenance, repair, and general service kits.

Air Dryers: The Basics

Air dryers for trucks and motor coaches are positioned between the air compressor and the "wet tank" to efficiently capture and filter out oil vapor, water vapor, and other contaminants that can otherwise enter and damage the air tanks and valves. With this, freeze-up during winter can be avoided, and the service life of the air valves can be prolonged.

The majority of truck air dryers are fitted with a replaceable desiccant cartridge for ease of maintenance. They are offered in 12-volt and 24-volt versions. Most over-the-road vehicles in North America use the 12-volt air dryers. The 24-volt systems, on the other hand, are typically installed on some heavy equipment and imported vehicles.

Haldex Pure Air Plus™ Air Dryer: A Closer Look

The Pure Air Plus air dryer features a built-in Turbo-Saver valve, ensuring minimal engine horsepower loss for improved fuel mileage. It is lightweight, so it will not significantly add to the weight of your truck or bus. It also has a compact design, making it easier to install and fit into place.

Another notable feature of the Haldex Pure Air Plus™ air dryer is the replaceable coalescing filter. It features a state-of-the-art filtration system designed to trap even the smallest oil contaminants and other particles. The air dryer’s connections allow trouble-free routing of plumbing for fast attachment to the vehicle. All connections are located at the bottom part of the dryer to prevent possible air-line low-point traps that can cause freeze-ups on the compressor discharge line.

Most Pure Air Plus™ air dryers are serviceable on both ends for easy and cost-effective on-vehicle servicing. Some features are not standard on all Haldex air dryers. These include a desiccant cartridge and a purge reservoir for easier maintenance, as well as mounting hardware for easy installation. If you want additional control over emergency braking and parking, Haldex also offers emergency braking and spring brake solutions that complement your air brake setup. 

Haldex Pure Air Plus™ Air Dryer General Service Kit

When your truck's thermostat reading drops and your brakes tend to become sticky, these are signs that the air dryer now needs servicing. This is where the general service kit comes into play. 

As its name implies, the Haldex general service kit is made for easy maintenance and service of the Pure Air Plus air dryer. The kit includes a coalescing filter, desiccant cartridge, purge shield, relief valve, and all associated hardware. With this general service kit, restoring the Pure Air Plus air dryer to its proper working condition becomes a straightforward task. Complementing the air dryer maintenance with Haldex truck clutch components can also help improve overall drivetrain performance and brake responsiveness.

Haldex Pure Air Plus™ Air Dryer Quick Maintenance Tips

As one of the air brake system's lines of defense against air particles and contaminants, keeping the air dryer in top shape is the best way to maintain smooth operation of your truck's air brakes. When servicing the air dryer using a general service kit, you might as well do the following:

1.       Drain your purge reservoir. This step, which can be completed in under 15 minutes, helps minimize freeze-ups. Remember that even a small portion of water can freeze after a few minutes, which can jeopardize a part of your air brake system, potentially causing downtime in your fleet.
2.       Check the air dryer for air leaks. A leak in the air dryer will cause the compressor to pump more air. Excessive compressor cycling can introduce more moisture into the air brake system or prevent the system from developing sufficient air pressure.
3.     Keep the air compressor discharge line angled downwards. If it is not turned away from the compressor, the discharge line can become blocked, forming a kink that could potentially freeze your discharge lines.

Performing these maintenance steps is much easier when you have a clear understanding of how air brakes work and how moisture impacts each valve. If your current unit is showing signs of internal wear or body damage, upgrading to a high-efficiency model, such as the Bendix AD-IP air dryer, can provide better protection against oil and water carryover for your entire air system.
