Kilfrost, manufacturer of de-icing fluids
used in the popular TKS systems installed on many different general
aviation aircraft types, announced it received FAA approval for its new
TKSsustain fluid. According to the company, TKSsustain is a more
environmentally friendly product than other options.
The FAA’s approval is for use with
Quest Aircraft Kodiak 100 models and comes after the new fluid passed
flammability, compatibility and in-flight testing.
Testing with several other aircraft types
is currently underway, with approvals anticipated later this year. The
new fluid, TKSsustain, is based on DuPont Tate & Lyle’s corn
sugar-based glycol product, Susterra.
“Because the fluid is based on glycol
from a sustainable source it’s much more environmentally friendly,”
explained Kilfrost’s chief executive, Gary Lydiate. “But it also
boasts significant handling benefits and ease of storage—in fact the
toxicity is so low that containers don’t even have to be marked with a
“The fluid is also more ecological than
ethylene glycol-based alternatives, with testing data suggesting a huge
65-percent increase in the speed of biodegradation, and the high ‘green’
glycol content ensures the fluid is a lower density which impacts
positively on an aircraft’s weight—sometimes reducing fluid weight
by as much as 10 percent,” he added.
According to Kilfrost, the new fluid also
performs better: The fluid’s freezing point is -70°C rather than the
-60°C expected from generic TKS fluids. The company says the new fluid
maintains its optimal viscosity through a wide temperature range,
allowing dependable de-icing performance in varying icing conditions.
Kilfrost also announced a strategic
partnership with CAV Aerospace—a major TKS system installer.
