DATACOOL HOSES

As liquid cooling demand has increased so has the reluctance to accept an off the shelf hose which had quite often been the case in the past. Traditionally the favoured choice of hose was one with an EPDM liner which has good general resistance but as with many things nowadays, the quality of the EPDM liner varies dramatically with (hose) distributors often sourcing on price due to market demand rather than on quality. This could potentially lead to contaminants leaching from the liner over a period of time or in extreme cases the hose actually breaking down due to inappropriate stress levels resulting in a failure and costly leak. Hydraquip’s DataCool hose assemblies offer unrivalled performance and unequalled benefits when compared against traditional hoses.

 

BENFITS

Silicone is seen as a superior elastomer to EPDM due to the added benefits it provides, as well as generally providing longer life in service. Not only is silicone excellent in extreme heat but it is also seen as a sterile elastomer, which reduces the risk of leaching.

DESCRIPTION

Hydraflex’s DataCool hose assemblies have been designed to meet the requirements that are requested for hose assemblies fitted into cooling systems within data centres, specifically on rear cooling doors. The technical properties of the hose allow for significantly more movement than traditional hoses including torsion twisting in addition to normal linear flexing. Hose assemblies are 100% visually inspected, pressure tested and individually marked with unique traceable information as per customer specification.

QUALITY & ASSOCIATED STANDARDS

In the unfortunate event of a fire normal silicone rubber will burn but does not give off toxic gases (including halogens) and has an ignition temperature of around 450°C/842°F. The fumes given off are also much less dense and tend to be white (silica) rather than the black fumes given off by other rubbers. A fire-retardant version to CEN/TS 45545-2-2009 is available on request. General performance is as quoted above.

APPLICATIONS & ADVANTAGES

  • Far superior torsion and twisting ability compared to EPDM hose
  • Identifiable colour difference between inlet and outlet
  • In the unfortunate event of a fire the hose does not give off toxic gases
  • Temperature Range -55°C to +170°C
  • Manufactured Lengths - 1 mtr/3.28ft (minimum) up to 5.5 mtr/18.04ft (maximum) subject to bore size. Longer assemblies available with a swaged joint incorporated between assemblies.

HOSE REDUCTION THROUGH FITTINGS

The arrow on drawing D2 denotes the ‘R’ measurement showing the ‘Minimum Bore Through Fittings (mm)’ which is reduced through the fitting tail, with a tolerance of +/- 0.2mm. The below measurements represent the minimum bore of each DN size; however, fittings will vary in bore size. For further information regarding this please contact out technical department.
