Data centre water cooling solutions

LETONE offers a high-performance range of products for water cooling applications,including rubber hoses,quick-connect couplings,stainless steel rigid pipes and wire braided corrugated flexible hose assemblies. These solutions ensure data center security and reliability,maintaining optimal temperatures for more efficient operation and steady performance.The 800 EPDM hose range is specifically designed to guarantee long service life, maximum safety,and ease of use in data center water cooling applications.

Resistant to Weather and Aging: The outerlayer isolates oxidative erosion, providing excellent weatherresistanceand UV aging resistance.

Flame Retardant rating-UL94 Vo: Complies with the UL94 V0 flameretardant standard, offering safe andreliableprotection for data centers.

Flexible And Easy To Install: The hose features a smaler bending radius, Equipped with UQDquick-connectfittings,it allows for easyinstallation andis suitablefornarrow.

Coolant Hose

Inner Tube: Black EPDM synthetic rubber.

Reinforcement: One or two layers of synthetic fiber braided reinforcement.

Outer Layer: Black weather-resistant, ozone-resistant, UL94 V0 flame-retardant special synthetic rubber.

Temperature Range: -40℃~+120℃(-40℉~+248℉).

Application: Suitable for air, water, water glycol, oil-water emulsion, antifreeze, phosphate ester hydraulic oil and other media fluids.
