QFM Filtration offers coolant filters with two SCA formulations tailored to specific engine needs:

• BTE™ (Balanced Treatment for Ethylene Glycol): Replaces DCA2, designed for systems using 30% to 60% ethylene/propylene glycol solutions.
• BTA PLUS™ (Balanced Treatment Additive): Replaces DCA4, suitable for systems with 0% to 60% ethylene/propylene glycol solutions.

For systems that prefer liquid additives, our coolant filters are also available without SCAs. If your equipment lacks a coolant filter, QFM offers a remote-mount option (CFB5000) that can be easily added to your system.

QFM’s Controlled Release Filters use a patented process to release SCAs only when heat and coolant flow are present, ensuring a consistent and even distribution. Unlike competitors’ filters that might "dump" additives all at once, our filters maintain optimal protection throughout the service interval, preventing cavitation erosion and corrosion.
