Pool Covers & Storage Rollers

SWIMPLEX TRANSTHERMAL POOL COVER

CONSTRUCTION

Blankets are fabricated from blue UV stabilised closed cell cross-linked polyethylene foam laminated between a UV stabilised woven blue fabric top and bottom. Lamination is accomplished by flame bonding between the layers. Material shall be manufactured to quality management standard AS-NZS-ICO.9002
Foam
Density 33 kg / cubic meter
Buoyancy 956 kg / cubic meter
Thermal conductivity 0.035 W / mK (DIN 53420)

WIND RETENTION (outdoor pools)

Each blanket shall have fitted along all longitudinal edges effective means of prevention for blanket dislodgement from the water surface. Weighted flexible rope of no less than 20 grams per metre contained within a mesh material, which is double stitched to the blanket edge, will be the minimum acceptable requirement.
The mesh material must have specific gravity greater than 1.0.

BLANKET EDGE PROTECTION (indoor pools)

Each blanket shall have woven protective mesh double stitched along its entire longitudinal edge to protect against wear and abrasion. Woven mesh shall be a minimum width of 25mm on both top and bottom of blanket edge.

END DETAIL

Both leading and trailing edges of the blanket shall be reinforced with double stitching
The leading edge of each blanket shall incorporate a reinforced stainless steel central pull eyelet for haul cord attachment
The trailing edge of the blanket shall be connected to its storage roller by attachments at intervals no greater than 600mm
4.4 Attachment cords shall be detachable from the roller tube and be of a material suitable for the application
All attachment cords and ropes shall be terminated in an effective manner by swagging with non corroding materials or termination with a suitable knot.

HAUL CORDS

Each blanket system shall be supplied with its own haul cord of adequate length to enable the user to attach it to the blanket and walk with it to the opposite end of the pool. One end shall have a non-corroding spring clip for connection to the central pull ring. Haul cords will be black and float in water.

HAND OPERATED AND MOBILE STORAGE ROLLERS

Rollers shall consist of a roller of sufficiently large diameter to enable the cover to be wound on with no creasing. This roller will rotate on shafts running in bearings connected to fully welded end carriages. For covers over 25m in length the rollers will be driven by handwheels. Covers 25m and under may be driven by crankhandles.
Handwheels, crankhandles, bearing housings and end carriages shall be chemically electropolished 304-grade stainless steel. Electropolishing shall be by process compliant with ASTM 380
Bearings shall be low friction and easily replaceable.
Rollers shall be of a diameter which when fully loaded with wet blankets will not deflect more than 1/300 of their span.
Anodising shall be to AS 1231-1985 and to a depth of 20 micron.
Rollers shall be fixed to their shafts in such a way as to distribute load stresses away from the very end of the tube and so as to minimise eccentricity of roller with respect to shaft.
Polyurethane, or similar bumper pads shall be fitted to the end carriages to prevent damage to and from collision with pool copings during deployment or retrieval operations.

ROLLER WHEELS AND BRAKING SYSTEMS

Roller wheels shall be nylon with stainless steel swivel castors. Swivel and wheel brakes will be used where the roller bears against a pool coping during its use.
Where no pool coping exists rollers must be located in position. This is done in one of two ways:
1/ Drop bolts: a robust stainless steel rod engaging into a stainless sleeve recessed into the floor surface and then retracted when not in use. This ensures exact positive roller positioning every time.
2/ Anchor stands: a device to stop roller movement when the roller is in use by using an over-centre strut to elevate the front wheels. The roller can be positioned anywhere provided the surface they work on is hard and flat
End of the roller with polyurethane or similar bumper pad to avoid damage to floors.

SUPPLY AND INSTALLATION TIME

The supply and installation time can be expected to be 3 - 5 weeks from placement of order.
