Nissens Automotive explains why, for the comfort and safety of the drivers of commercial and public service vehicles, the performance of air conditioning and climate control systems is essential.
Nissens Automotive, a thermal management specialist, does its best to ensure its distribution partners are ready with a range of its key system components range on their shelves, ready for the A/C season.
Two of the most frequently replaced parts are compressors and condensers, for which the company has a comprehensive offering covering the vast majority of heavy-duty applications, but naturally the complete A/C programme also includes interior blowers, evaporators, receiver-driers, fans and, most recently, thermal expansion valves (TXV).
The convenient and safe choice
Whereas distributors focus on the proper range and availability of parts, technicians want to be sure the service procedure they follow is carried out successfully, with no extra hassle, and that it ends with a happy customer – whether owner, operator, or fleet manager. This means that the service must result in the A/C system performing to its optimum, with the trouble-free operation of its components, an outcome that is made considerably easier by selecting Nissens products when servicing the system.
All Nissens products are developed and manufactured according to Nissens’ market-recognised quality standards. This ensures that they are perfectly finished, thus enabling a trouble-free, fast installation. The functionality of every component is thoroughly tested so it matches the original equipment (OE) part, which ensures its optimal thermal performance.
The majority of Nissens A/C parts are also ‘first fit’ products, which means the technician gets everything that is needed for their correct installation within the product box. Furthermore, Nissens’ condensers are corrosion protected, which prolongs their lifespan considerably.
The technical know-how
Alongside its premium quality components, Nissens has a reputation for its technical support, which it provides to installers through a variety of forms from print to online. One of the many helpful pieces of best practice advice and fitting tips is to always replace the TXV when installing a new compressor.
Despite its small size, the TXV plays a crucial role in ensuring the A/C system works to its correct parameters. The valve’s operational characteristics influence not only its overall performance, but also the proper operation of other important components. It controls – among other things – the refrigerant’s flow and working factors, and these have an important influence on the A/C compressor workloads, potentially affecting its lifespan and even provoking premature failures. It is, therefore, important that the valve operates accurately in a specific way, as determined by the particular system design.
Nissens A/C parts facts
Nissens heavy duty A/C system components total more than 200 parts, covering the most popular truck applications. The range includes compressors, condensers, interior (heater) blowers, fans, heaters, evaporators, receiver-dryers, and TXVs.
Nissens’ compressors are an example of its wide range of ‘first fit’ products – pre-filled with the right type and quantity of lubricant, including O-rings, as well as electrical harness and connectors or a protective pre-filter, whenever needed.
All Nissens TXVs are equipped with O-rings and mounting bolts, whenever applicable to the OE part. Nissens condensers include O-rings and are protected from corrosion with a specially designed coating. In saltwater tests, condensers treated with this corrosion protection function up to eight times longer than non-protected condensers.
