With the new RRU ECO Klingenburg continues the product offensive it started with the Rotor 5.0
The new design of RRU ECO offers you many advantages
More power – less pressure loss
For housing dimensions from 600 to 2550 mm, the difference between the storage mass and the housing is only 50 mm, even with a minimum installation depth of just 290 mm.
For our customers, this means: Even more power and less pressure loss with the same cross-sectional area in the air conditioner.
We produce the RRU ECO on the basis of a completely new design. Its housing is flush on the outside with no protrusions.
It has a particularly high torsional rigidity with no welded joints.
And you will continue to enjoy the full flexibility that Klingenburg has always offered in terms of external dimensions. We manufacture the housings with millimetre precision, exactly according to customer requirements. There are no fixed grid dimensions.
Optimised storage mass
A new wave geometry provides optimal storage mass performance.
It is based on our Rotor 5.0 software.
Choose from a total of six different wave heights to obtain the optimal solution for every application.
We also produce the storage mass with millimetre precision according to customer requirements.
The RRU ECO´s new design has also allowed us to optimise our sealing concept. The standard brush seal rotates together with the storage mass – a particularly low-wear and low-resistance process.
Adjustable purge section
Der RRU ECO has an adjustable purge section that you can adjust to the respective pressure situation in two stages. This allows you to minimise the co-rotation of exhaust air into the supply air and thus keep fresh air losses as low as possible.
We have significantly improved the handling. Units of all sizes can be moved with an overhead crane.
Intelligent drive system
The RRU eco is driven by a stepper motor as standard.
The control unit naturally has a Modbus interface. The power consumption needed to reach the drive torques is low.
Quick-Check RRU ECO – All benefits at a glance
- Optimal utilisation of the air conditioner cross-section (difference rotor Ø/housing 50 mm)
- Maximum torsional rigidity
- o protrusions, flush exterior
Optimised storage mass geometry
New wave heights based on our Rotor software 5.0 for the best possible performance data.
Adjustable purge sector
Purge sector adjustable in two stages (2.5° or 5°), suited to the pressure situation. Prevents co-rotation ratios and keeps fresh air loss as low as possible.
The RRU ECO easily meets the applicable requirements of the European Design Directive for ventilation units ErP Lot 6.
The RRU ECO meets all hygiene requirements for ventilation air conditioning systems under VDI 6022.
Rotor diameter of 550 to 2500 mm and six different wave heights allow optimum operation for every application and air condition.
