CVR Series Procurement Note

The supplied specification states that the CVR Series packaging does not include filling foam and requires a minimum order quantity of 10 units. This requirement should be considered for distributor, project, and wholesale procurement.

Reinforced Carbon Steel Construction

The LC and CVR Series use a reinforced carbon steel structure rather than a lightweight plastic housing. The reel base and support brackets are manufactured from thick-gauge carbon steel through stamping, creating a rigid support structure for the rotating reel assembly.

The support structure has an important mechanical role. During hose deployment, the operator applies an outward pulling force to the hose. During retraction, the spring mechanism applies a rotational force to the reel. The support bracket must therefore maintain the alignment between the reel, spring mechanism, hose guide, and mounting point.

Mold-Stamped Reel Disc

The reel disc is manufactured through mold stamping and then formed into the required reel geometry.

This manufacturing method creates a consistent winding surface for the hose. A controlled reel diameter is important because the hose needs to wind layer by layer without excessive interference between adjacent turns.

The disc structure also helps keep the hose contained within the reel during storage.

For longer hoses, such as the 21 m LC670 OLP and LC870 OLP configurations, the reel needs sufficient winding capacity to accommodate the complete hose length. The model specification therefore combines hose length with the corresponding reel size rather than treating hose length as an independent parameter.

Powder-Coated Surface Treatment

The carbon steel reel structure receives a powder-coated surface treatment. Powder coating provides a continuous protective layer over the exposed steel surface and improves resistance to routine abrasion and environmental exposure during normal industrial use.

Protection against routine exposure:

• Workshop dust & routine handling
• Water splash & cleaning operations
• Mechanical contact & indoor/outdoor atmospheric exposure

Note: The powder-coated finish should not be interpreted as unlimited corrosion protection. For marine environments, aggressive chemicals, continuous immersion, or highly corrosive atmospheres, material and coating compatibility should be evaluated separately.

Spring-Driven Rewind Mechanism

The LC and CVR Series use a spring-driven rewind mechanism. When the operator pulls the hose outward, the reel rotates and the internal spring stores mechanical energy. When the hose is released according to the reel's operating mechanism, the stored spring energy drives the reel in the opposite direction and returns the hose to the reel.

The main advantage is that the operator does not need to manually coil a long hose after each operation. For maintenance departments, production lines, workshops, and service stations where hoses are used repeatedly throughout the day, automatic rewind can reduce hose handling time and maintain a more controlled hose storage arrangement.

Adjustable Guide Arm

One of the practical features of the LC and CVR design is the adjustable guide assembly. The guide can be adjusted to eight different directions, allowing the hose outlet direction to be matched to the actual installation position.

This is particularly important because a fixed hose outlet may force the hose to bend sideways immediately after leaving the reel.

Matching layout requirements:

• Pneumatic tools & water supply points
• Workstations & service equipment
• Vehicle maintenance bays & production machinery

Before Ordering Checklist:

Working Pressure & Temperature

The supplied specification identifies the LC and CVR series as low-pressure air/water hose reels with a maximum temperature of 65°C.

Product Dimensions (mm)

All dimensions are in millimeters for planning mounting positions and installation clearances.

Why This Series Is Suitable for Demanding Industrial Applications:

• Reinforced Support Structure: Thick-gauge stamped carbon steel base and brackets provide heavy-duty mechanical support.
• Controlled Hose Winding: Formed reel disc creates a defined winding surface for smooth layer-by-layer retraction.
• Automatic Rewind: High-performance spring mechanism returns hose to storage position automatically.
• Adjustable Hose Direction: 8-position guide adjustment adapts outlet direction perfectly to any mounting spot.
• Optional Reel Movement: Swivel/swing brackets offer extra flexibility across wide coverage areas.
• Multiple Capacities: Available in 10 mm, 13 mm, and 19 mm I.D. to match distinct flow needs.

Installation Considerations

• Mount on Rigid Structure: Must withstand weight & repeated pulling forces.
• Align Hose Path: Adjust guide direction to prevent immediate sharp bending.
• Maintain Rewind Clearance: Provide space for rotation and hose retraction.
• Check Connection Compatibility: Verify inlet and outlet thread standards.
• Consider Working Radius: Match hose length to farthest working point.
• Evaluate Environment: Confirm suitability for corrosive or outdoor exposure.
