DESCRIPTION

Hydraflex have been supplying flexible assemblies for chilled ceiling and beams for over 30 years and have an in depth understanding of the requirements and expectations of the industry. Hydraflex’s range of quick release couplings ensure a problem free installation, reducing installation time by up to 40%; with continued ease for servicing and maintaining systems. With a 3:1 safety factor, a temperature range from -20°C to +85°C in a variety of bore sizes, Hydraflex’s range of ceiling hoses are also tested and approved by BSRIA. Ceiling assemblies can be fitted with vapour sealed class O insulation to ensure maximum efficiency and fitted with end caps.

ASSEMBLY MEASUREMENTS

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.

GEOMETRY AND MINIMUM BEND RADIUS

WORKING AND THEORECTICAL BURST PRESSURE

PRESSURE DROP

Formula:

Pc = (TxL) + R (in mbar)

Pc = Pressure Drop in mbar

T = Pressure drop in mbar for one meter of hoses according to its flow capacity in M3/h

(Schedule 1)
L = Hose Length in meters

R = Pressure drop in mbar caused by two fittings (male x female), same condition than ‘T’ (Schedule 2)

Example:
Flexible hose DN13 length 500mm 1 F – M, flow capacity 1000 l/h
Pc = (3 mbar/m x 0.8m) + 23 mbar = What?
Flexible hose DN25 length 800 1 F – N, flow capacity 1500 l/h
Pc = (3mbar/m x 0.8m) + (2.5 mbar x 1.5) = What?
