Go Chiller Astro Ultimate is a premixed water-based computer
coolant which uses a premium inhibitor formulation to protect
computer cooling systems such as radiators, pumps, and
water blocks, and ensure efficient thermal performance when
properly maintained.

The inhibitor formulation meets ASTM D1384 corrosion
standards preventing foams, rust, corrosion, cavitation, scaling,
oxidation and degradation of the cooling system for at least
five years. It is also not harmful to rubber seals or hoses

Before using Astro Ultimate coolant, Flexegraph
recommends flushing the cooling system prior to a
complete service refill pre-cleaning the cooling system by
draining the existing coolant and chemically cleaning the
system to remove any rust, dirt, oil and built up residue.
Go Chiller Prep-Cool effectively cleans the system and
prepares the cooling loop for new coolant
