Penray debuts new cooling system treatment

400016 Pencool 4000Penray has introduced a new additive, Pencool 4000, specifically formulated for nitrite-free Extended Life Coolants (ELCs) used in heavy-duty, commercial applications.

According to Penray, this new blend is compatible with all ELCs, including those families of Organic Acid Technology (OAT) and Nitrited Organic Acid Technology (NOAT) coolants.  Pencool 4000 also is said to provide important corrosion inhibitors in order to enhance and maintain the effectiveness and service life of these coolants.

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 Penray says. In doing so, it increases uptime, reduces maintenance costs, and helps to extend the life of the vehicle by reducing engine wear, the company says.

“The term ‘Extended Life Coolant’ might be interpreted to mean that such products never wear out. And that would be incorrect,” says 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.”

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. Penray says it protects against rust and corrosion that are common in cooling systems, extending radiator life. This 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, the company says.

Pencool 4000 is ideally suited to over-the-road trucks and local delivery vehicles, as well as mobile off-highway (MOH) vehicles and construction equipment, the company says.

“We recommend periodic coolant testing to monitor the condition and effectiveness of the corrosion inhibitors used in heavy-duty cooling systems,” says Muth. ” 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. 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.”

Pencool 4000 is supplied in convenient 16 oz. bottles, as well as in 5-gallon pails and 55-gallon drums. With the addition of Pencool 4000, Penray covers conventional applications with Pencool 2000 for marine use, Pencool 3000 for heavy-duty truck applications and Pencool 4000 for ELC applications covering marine and heavy duty vehicles.
