Select a hose reel compatible with the exhaust extraction system
A hose reel improves ergonomics and keeps the workplace tidy, but it must also be compatible with the exhaust extraction system in terms of fluid dynamics. Hose length, diameter, temperature resistance, and the retraction system all influence practical use. The reel should not be considered in isolation, as every additional meter of hose increases pressure loss.
Here’s what you should look for when making your selection
✔ Required hose length and working radius
✔ Hose diameter
✔ Permissible exhaust gas temperature
✔ Mounting height and installation configuration
✔ Retraction System and Operation
✔ Connection to a pipe network or fan
Manual, spring-assisted, or motor-driven
The most suitable retraction method depends on frequency of use, hose weight, and installation height. For workstations in regular use, a convenient retraction system can significantly simplify daily handling. During planning, it must also be ensured that the hose reaches all the way to the vehicle.
Hose Routing and Pressure Loss
The longer and tighter the hose run, the greater the resistance. For this reason, unnecessary excess hose length and tight bends should be avoided. The fan must overcome the pressure loss caused by the hose, hose reel, connection line, and capture element at the required flow rate.
Planning at a Glance
| Criterion | Meaning | Note |
|---|---|---|
| Hose length | Reach | Do not make sentences unnecessarily long |
| Diameter | Flow rate/Pressure Drop | Tailored to the vehicle and system |
| Temperature | Hose Resistance | Take temperature spikes into account |
| Withdrawal | Ease of Use | Take frequency of use into account |
FAQ
How long should the hose be?
As long as necessary for the working radius, but not unnecessarily longer, since additional hose length increases pressure loss.
Can an existing fan be reused?
That depends on whether it can overcome the additional system resistance at the required air flow rate.
Is a motorized reel always better?
No. The right solution depends on the application, hose weight, installation height, and desired ease of use.
What is important when exhaust gas temperatures are high?
The hose and all temperature-sensitive components must be designed for this purpose.
Advice on Hose Reels
The most important factors for selection are the vehicle, temperature, hose length, diameter, and installation situation.
