Antivriesmiddel/koelmiddel 1 L gebruiksklaar, EK Water Blocks, wit

EK Water Blocks Antifreeze/Coolant 1 L ready-to-use in white is a premixed coolant formulated for closed liquid cooling loops in PCs and compatible systems. Supplied in a 1-litre bottle, this ready-to-use coolant eliminates the need for dilution and streamlines filling and maintenance. The formula provides corrosion and biological growth inhibitors, stable pigment dispersal that does not sediment over long periods, and heat transfer properties suited to computer liquid cooling applications.

Advantages

This EK-CryoFuel Solid premix includes synergistic corrosion inhibitors that protect metals commonly found in PC cooling circuits, along with scale and biological inhibitors to reduce fouling. The coolant is chemically stable, low-viscosity and engineered for long-lasting color stability without pigment residue. It delivers good heat transfer characteristics and a high specific heat while remaining non-toxic and biodegradable under standard test conditions.

Suitable for

• Closed-loop PC liquid cooling systems (CPU and GPU blocks)
• Custom water cooling loops in desktops and workstations
• Pre-built liquid-cooled systems requiring a premixed coolant
• Maintenance top-ups and coolant replacement in compatible circuits

Key specifications

• Form: ready-to-use premix, 1 L bottle
• Colour: white (non-transparent)
• Chemical properties: low viscosity, chemically stable
• Protection: contains corrosion inhibitors for copper, brass, aluminium and stainless steel
• Biological control: contains biological growth inhibitors to reduce fouling
• Thermal properties: good heat transfer characteristics and high specific heat
• Environmental: biodegradable formulation (approx. 90% in 10 days)
• Safety: non-toxic under normal handling conditions

How to use

Use this coolant directly from the bottle; no dilution is required. Prior to filling, drain and flush the existing loop according to the system manufacturer's instructions to remove old coolant and debris. Fill the loop slowly to avoid air entrapment, then run the pump at low speed while checking for leaks and gradually bleed air from the circuit. After the system stabilizes, verify fluid level and top up as needed. Follow standard safety and handling guidance when working with liquid cooling systems.

Recommendations

For best results, use only with materials and components compatible with standard PC liquid cooling systems and maintain the loop regularly: inspect for leaks, replace or clean filters and radiators as needed, and replace coolant within a period consistent with the manufacturer's shelf-life and maintenance guidance. Avoid mixing different coolant formulations to prevent chemical incompatibilities and sediment formation.
