Penray has introduced its new Pencool 4000 with two distinct applications. The first application is used as a water-only ELC corrosion inhibitor for marine applications. The second application is as an additive specifically formulated for nitrite-free Extended Life Coolants (ELCs) used in heavy duty, commercial applications.
“This new blend is compatible with all ELCs, including those families of Organic Acid Technology (OAT) and Nitrited Organic Acid Technology (NOAT) coolants,” according to the company. “Pencool 4000 provides important corrosion inhibiors in order to enhance and maintain the effectiveness and service life of these coolants.
The company mentioned that this formulation adds specific benefits to ELCs used in commercial and heavy-duty vehicles and equipment, by providing excellent corrosion protection and extending the service life of the coolant. “In doing so, it increases uptime, reduces maintenance costs, and helps to extend the life of the vehicle by reducing engine wear,” Penray added.
Pencool 4000 is nitrite-free, and provides protection to all metals typically wetted by coolant; including steel, cast iron, copper and aluminum, as well as seals and elastomers found in cooling system hoses. It protects against rust and corrosion that are common in cooling systems, extending radiator life. In addition, the company said, the product contains special additives that protect against wet sleeve liner pitting, reducing long-term maintenance costs. It also helps reduce cavitation erosion, which can compromise cooling system efficiency and cause hot spots resulting in engine damage.
Pencool 4000 is suited to over-the-road trucks and local delivery vehicles, as well as mobile off-highway (MOH) vehicles and construction equipment. It also can be used for marine applications that use sealed cooling systems, and which often operate on water -only coolant.
"The term 'Extended Life Coolant' might be interpreted to mean that such products never wear out. And that would be incorrect," notes Steve Muth, chief chemist for Penray. "While these are excellent products and do last longer than conventional coolants, supplementation with a product like Pencool 4000 is important to maximize their extended service life."
"We recommend periodic coolant testing to monitor the condition and effectiveness of the corrosion inhibitors used in heavy-duty cooling systems," Muth added. "And we certainly continue to do so with ELCs as well as with traditional coolants. When testing shows reduced protection levels, the use of a supplement like Pencool 4000 as a booster restores coolant chemistry and performance.”
"While we continue to offer powerful and effective supplements for conventional coolant blends, this new Pencool 4000 was specifically developed for the new-generation ELC, OAT and NOAT coolants,” he mentioned. “Penray has worked hard to devise new ways to fight the corrosion and cavitation that are symptoms of compromised ELCs. Reducing the frequency of coolant flushes keeps vehicles in service for longer periods of time and promotes longer engine and vehicle life."
