GLOBAL HARMONISED STANDARD

Guaranteed REITZ quality

Quality

One of the central REITZ promises to our customers is a pledge in which we guarantee REITZ quality according to German standards, regardless of whether your fan is manufactured in Höxter, Hyderabad or Suzhou. Well-documented quality management with Group certification pursuant to DIN ISO 9001 confirms that which you can expect from us anywhere in the world: excellent engineering and design, first-class design quality and high performance made by REITZ.

SYSTEMATIC RELIABILITY

The same quality standards which apply to production at our headquarters in Höxter also apply to our production facilities in India and China. Based on a high degree of vertical integration and certified quality management, we leave nothing to chance to impress our customers with durable fan technology.

Materials tailored to applications

First-class product quality begins with the careful selection of materials by our specialists for standard and special materials.

Certified production

REITZ customers value quality workmanship documented through certified quality management pursuant to DIN ISO 9001 and other certificates (welding, non-destructive testing, safety, environment, health and many more).

Endurance tests

No REITZ fan leaves production without being thoroughly inspected through a number of measures (balancing of impellers in two planes for running smoothness and durability, finite element calculation to check tension in dynamically stressed components, non-destructive crack testing using a dye penetration test, vibration analysis).

Power measurement

Sizes up to 1,000 kW can be reliably inspected and measured on our own test bench at our headquarters in Höxter.

Service

REITZ fans reliably fulfill their tasks in both industrial centres and the most remote regions of the world. The worldwide REITZ service network has been continually refined over decades, enabling us to assure completely uninterrupted support today. REITZ engineering tools which have proven their reliability under practical conditions ensure the smooth and efficient performance of your system at all times.

CFD – FLOW ANALYSIS

The CFD analysis is a core component during the feasibility inspection. The flow situation in a planned system component is simulated and evaluated during this, and it soon becomes apparent whether and where optimising potential exists and at which points the maximum effect can be achieved with minimum investment costs. Computational fluid dynamics therefore allow us to reproduce real conditions and, equally, construct revealing “what if” scenarios. All results obtained are compiled for you in an informative report.

STRESS AND MODAL ANALYSES

The finite element method is indispensable for precision engineering of impellers. Detailed stress analyses provide information on optimum dimensioning, ruling out any surprises during operation. Material and sheet thicknesses can be reliably balanced and determined in relation to the design. Moreover, it is also possible to obtain valid statements on the stress and strength of the impeller, allowing any risk to be reduced to a minimum.

DRIVE OPTIMISING

We analyse natural frequency and resonance ranges on the basis of years of experience to prevent any possible damage. We parameterise the entire drive system (fan, motor and converter) during this to ensure that the permissible vibration characteristics pursuant to ISO 14694 and DIN ISO 10816-3 are observed. Measurement up to 10,000 kW is conducted on our own test bench and on site. The parameter lists are a component part of the final documentation.

PLANT MODERNISATION

Practical experience indicates that a system of average efficiency can be transformed in the majority of cases into a veritable miracle of productivity and efficiency through the targeted partial modernisation of individual components.

- Replacement of used fans or components
- Energy saving through the use of impellers with higher levels of efficiency
- Energy saving through the use of energy efficient drive systems (e.g. variable speed control with frequency converters). Savings of up to 30%. Investment costs amortise on average within only two years.
- The advantages of speed control: 100 % needs-based consumption, linear control characteristics, quiet running, perfect start-up behaviour, smooth mechanical running → Download energy efficiency brochure

FOUNDATION PLANNING AND REALISATION

When it comes to constructing a foundation with long-term solidity and resilience, we take charge of preparatory tasks such as layout, planning, dynamic and static calculations, the shell and reinforcement drawing, steel quantity lists and building instructions to ensure that you have all the basics required for the safe and professional realisation of the foundation.re und fachgerechte Ausführung des Fundaments verfügen.

SOUND AND THERMAL INSULATION

Both sound and thermal insulation are component parts of our engineering for optimum insulation. Housing surfaces and split joints, inspection openings, flexible connections and the vicinity of the shaft seal are the focus of attention during this. We take the adequate securing of insulating material, the thermal expansion of the system part, waterproofing in outdoor installations and, on request, the accessibility of components into consideration in this respect.

The perfect design for every application
