Reels

Stands upright by itself – round reels need a cradle
More practical – one piece instead of two (no stand)
Compact design saves transportation cost
Fork pockets make loading/unloading on trailer easier
Round center has room for fitting and drive shaft
45° edges to prevent nicks when retrieving or deploying
Reel weight loaded with
- 200mm diameter ~ 765 kg
- 250mm diameter ~ 930 kg
- 300mm diameter ~ 1,225 kg

Deployment System Patent Pending

Coil and deploy driving forward. Can deploy one 200m length in less than a minute consistently (level ground)
Not necessary to drive over the hose when deploying, which prevents damage if a rock is underneath the hose.
Direct Drive Chain System for coiling works directly from the hydraulics of a loader. Minimum 3,600 kg loader
Works in rain, sleet, or snow – not reliant on a wheel driven system with tires
Pin system locks loaders forks to deployer for operation in hills and ditches
Manual brake for deploying
Detachable gate, squeegees hose and keeps hose in line with reel on coiling
Expanded metal panels protect workers while in operation
Labour Efficient – deploy or retrieve several kilometres of hose per hour with a crew of 2 (at the most you may need 3)

Through-the-Weave vs. 3-Ply Layflat Hose

Compared with hoses made from a blend of nitrile rubber and PVC, urethane hose offers 5X the abrasion resistance, less elongation, and far superior puncture resistance.

Polyurethane (PU) hose, is manufactured a couple different ways: “three-ply” and “through-the-weave.” 3-ply hose is relatively labour intensive, where a long tube of urethane is glued over a woven polyester hose jacket. Then it is turned inside-out, and an outer PU cover is glued to the other side of the jacket. The final step is to fill the hose with steam, which cures the glue and creates the adhesion between the various layers. It’s important to note that the outer layer of urethane is pin-pricked with thousands of small holes to allow gases to escape during the steam curing process.

Through-the-weave layflat hose also begins with a woven polyester hose jacket. However, at the end of a plastics extruder is specialised tooling, through which the jacket is penetrated and coated with hot, molten thermoplastic polyurethane (TPU). The urethane, in liquid form at such a high temperature, is literally forced through all the gaps in the weave of the hose jacket. The hose exits the die and begins to cool immediately. Urethane completely encapsulates the woven jacket and provides a watertight hose wall as well as incredibly tough protection for the hose jacket. The hose jacket, in turn, provides all the pressure capability for the hose, as well as limiting elongation and expansion. Once the hose is cooled it is fully formed, then coiled on a reel and ready to be tested. This through-the-weave method is a more difficult manufacturing process than 3-ply, but well worth the extra difficulty as it results in a much stronger final product.

We’ve chosen to supply our customers a through-the-weave layflat product, as we believe modern through-the-weave construction represents the best design in today’s large diameter layflat hose. 3-ply hose technology is adapted from the fire hose industry, a manufacturing technology that has been around for at least 140 years.

Our layflat hose uses no glues or adhesives which prematurely fail when exposed to moisture, heat, UV exposure, repeated flexing, or dry out naturally over longer periods of time. Our layflat hose is free of pinholes and the cover will not delaminate. Rather than sit on top of the woven polyester, our TPU is an integral part of the hose, working in concert with the hose jacket. Our hose will not “snake” along the ground due to excessive elongation.
