CHEMICAL ASSET PROTECTION FOR THE COOLING CIRCUIT.
Diesel engine cooling systems face two simultaneous corrosion threats: electrochemical attack on aluminum, copper and steel surfaces, and cavitation erosion on cylinder liner external surfaces driven by pressure waves from piston firing events. Both failure modes are prevented by maintaining SCA (Supplemental Coolant Additive) chemistry within a tight concentration corridor.
COOLTECH™ deploys a controlled gradual release mechanism that replenishes SCA chemistry as it is consumed through the service interval — maintaining protection concentration without peaks or valleys that conventional coolant change schedules cannot guarantee.
The gradual dosing system prevents the inhibitor concentration spikes that occur when SCA is added as a single dose at service — high initial concentration that drops progressively to sub-protection levels before the next service interval, leaving the cooling circuit unprotected for a portion of every service cycle.

COOLTECH™ · SCA ADDITIVE RELEASE PROTECTION ELEMENT
THREE PROTECTION MECHANISMS FOR COOLING CIRCUIT INTEGRITY.
ADDITIVE RELEASE CONTROL
COOLTECH™ controlled additive release matrix delivers SCA chemistry into the coolant stream at a rate matched to consumption. As inhibitor concentration falls through use, the release rate increases to compensate — maintaining the target protection corridor without operator intervention between service intervals. This active concentration management eliminates the unprotected coolant condition that occurs at the end of conventional SCA dosing intervals.
VAPOR PREVENTION LAYER
Cavitation erosion on cylinder liner surfaces begins with vapor bubble formation at the liner wall during pressure wave events from piston combustion. COOLTECH™ vapor prevention chemistry forms a protective molecular layer on ferrous surfaces that suppresses the nucleate boiling that initiates bubble formation. By preventing vapor bubble genesis at the metal surface, COOLTECH™ eliminates the cavitation collapse energy that erodes liner walls over time.
HEAT MANAGEMENT BARRIER
The SCA film maintained by COOLTECH™ on all cooling circuit metal surfaces also functions as a thermal transfer optimization barrier. The molecular protection layer is calibrated to maintain metal surface contact without creating thermal insulation effects — protecting against corrosion while preserving the heat transfer efficiency between the engine block and the coolant stream that cooling system design depends on.
FIELD SPECIFICATIONS
“Cylinder liner pitting from cavitation was costing us an average of $12,000 per engine rebuild. COOLTECH™ SCA technology has maintained coolant chemistry within specification continuously for 18 months — zero pitting events recorded across our generator fleet.”
WHERE COOLTECH™ PROTECTS
COOLTECH™ SCA protection is the thermal system defense choice for diesel engines with aluminum and cast iron cooling circuits.
Long-haul diesel engines with complex cooling circuits combining aluminum heat exchangers, copper heater cores and cast iron engine blocks — all requiring simultaneous SCA protection from a single dosing system.
Stationary diesel gensets operating on extended service intervals where SCA depletion between service events is a known failure risk. COOLTECH™ gradual release maintains protection through the full interval without mid-cycle coolant chemistry intervention.
Seasonal-use agricultural equipment where cooling system corrosion can advance undetected during off-season storage if SCA concentration falls to sub-protection levels. COOLTECH™ maintains active protection chemistry regardless of duty cycle.
Off-highway diesel equipment with large displacement engines subject to high thermal cycling rates. Cavitation erosion on cylinder liners is an accelerated failure risk in heavy-load mining applications — COOLTECH™ vapor prevention layer is the direct countermeasure.
Construction equipment operating in environments where coolant quality degradation through ingress of environmental contaminants is a constant risk. COOLTECH™ SCA maintenance compensates for dilution events that reduce inhibitor concentration below protection threshold.
Stationary industrial engines and generating sets in process industry applications where unplanned cooling system failures cause production disruption with significant downstream cost consequences.
