BUSINESS UNIT INDUSTRY This business segment supplies compact basic fans and customised solutions to industrial plant engineering companies and contractors all over the world.

The extensive know-how of one of the most traditional companies, Pollrich Ventilatoren, guarantees ongoing innovation in the field of heavy duty centrifugal fans.

Executed units with a flow rate of 1 million m³/h and 35,000 Pa, at process temperatures up to 450 °C, and drive ratings up to 4 megawatts are current applications for Pollrich.

The substantial portfolio of standardised basic fans rests upon a modular design system of 21 impeller sizes [400 to 3150 mm] with 10 different diameter ratios and 8 distinct blades geometries.

A system which allows adapting the fan design to an amazing number of application cases – and this to reasonable costs and delivery schedules.

Special operational process conditions are checked by using flow simulation techniques and FEM calculation in close cooperation with the R&D department.

Example: Aluminium works at Patagonia.

The plant is producing aluminium at a rate of

app. 250,000 tons per year.

Application:

Smoke gas cleaning of the melting oven,

operating 24 hours/day at a temperature

of 150 °C.

Execution:

3 main fans HREK01 80,000 m/h, 68 mbar,

max. 200 °C. 1 SDS fan HREK01 65,000 m³/h,

12 mbar, max. 250 °C. The electric motors,

designed for outside operational conditions have

been part of the supply. The commissioning

during 2 weeks has been made by the

company’s specialists.

Building services engineeringUnderground car park ventilation

BUSINESS UNIT SMOKE EXTRACTION Focussed on smoke extraction fans, the actual importance of mechanical ventilation for safety and rescue purposes is well emphasised within this business segment. The staff consists of experts for designing a comprehensive safety package beginning with projecting an installation and possibly ending with monitoring its later operation.

For the field of underground car parks certified consultants, acting as sales agents, will support the general concept of a complete installation: Technical selection and placement of jet fans, design of the CO-alarm-system, calculation of the necessary intake and exhaust air flow rate in case of fire backed up by a CFD simulation.

All smoke extraction fans are DIBt certified and CE-conform. The product range includes actually all fire-resistance classes from F200 to F600.

- Axial middle and high pressure fans- Axial and centrifugal roof extraction

fans up to 80,000 m³/h - Car park jet fans, unidirectional and

reversible, axial and centrifugal- Single intake belt driven centrifugal

fans up to 100,000 m³/h.

Monitoring bearing operational condi-

tions BeaWatch®

is based on a combined analysis of:

1. Vibration acceleration compared to

defined bearing frequencies

2. Bearing temperature

By combining and evaluating these data a

reliable statement of the bearing status is

possible at any time.

Sectional ventilation

Reliability of the planning is the customer’s requirement. For this reason close cooperation between consultant, principal, operator and the own R&D department, based on a precise system analysis is essential. Modern methods as CFD simulation and FEM calculations, as well as standard laboratories for aerodynamic and acoustical measurements will help to achieve an optimal integration of the installation components.

Reliable operation will be achieved with a high product quality and with a product range for a wide band of different requirements. The core range consists in the basic line of jet fans being made in appropriate materiel according to the application and its specific requirements. Portfolio:- Axial intake fans from DN 250- Reversible tunnel jet fans up to

DN 1600- Underground fans for intake

and exhaust up to DN 2500- Command, control and

monitoring including the necessary measuring equipment

Fans with DIBt-certificate and CE-conformity declaration are available.

Example: Metro Warsaw

Since 1995 the 23 km long metro

line n°1 is operating from north to

south of Warsaw. About half a million of

passengers are using this underground

daily. An extension from east to west is

under construction and the opening will

be in 2014.

Project definition:

Calculation of pressure losses by

CFD simulation.

Design of the fans and supply of the

measuring equipment.

Realisation:

Supply of 34 smoke extract fans of

the Terrajet line with diameters of

1600/1800/2000, temperature class

Environmental Technology

BUSINESS UNIT ENVIRONMENT The economy around environmental concern has developed to a key business field, whose dynamical growth is requiring corresponding strategically follow up for the sales organisation. This business segment is covering railway, shipbuilding, aeronautics, wind and water power generation, recycling technology, waste treatment, sound attenuation, etc.

Experience acquired over years in solving requirements to extreme conditions are giving to us a valuable platform for future tasks: seawater resistant execution of fans for ships, shock proof units for rolling railway stock, special material adaptations for being used in car test blowers – all these extraordinary achievements are adding expertise to our tremendous knowledge base of fan technology and to future developments. The guide line is to develop energy efficient, long lasting products meeting highest quality requirements for most various applications. The close cooperation with the R&D department stands for optimised solutions delivered to the customer.

The segment of environmental technology has to its disposal a wide portfolio of centrifugal, axial, and plug fans.

Energy Efficiency: This means sustainability for manufacturing and

products.

During the conception phase focus is put on

environmental impact, energy balance and

recycling possibilities, during the design phase the

product energy consumption is under permanent

improvement.

Thus using electronic controls, energy efficient

drives and latest aerodynamic research results a

first class product will be created at the end.

BUSINESS UNIT SERVICES

The business segment services provides all activities, necessary for a successful start-up and a smooth operation of a fan installation. This includes the provision, supply, and installation of spare parts – even for fans of other manufacturers.

Services mean too to offer and supply maintenance, consulting, and optimisation on existing installations. Individually shaped maintenance schedules and contracts or those prepared according to EN 12101 for smoke and hot gas exhaust will provide substantial benefits to the unit operator.

Information and advice concerning most recent technologies and developments in order to modernise existing installations and thus increasing power and cost efficiency are part of the activities offered by this business segment.

Proposals for a possible optimisation of existing installations:- Set up of ventilation installations- Vibration and sound analysis - Frequency analysis- Bearing status analysis and monitoring- Flow rate measurements- Active power measurements- Differential pressure

measurements- Rpm measurements- Alignment of coupling drives

with laser unit- Balancing of all rotational

machinery on site

Example: Cement mill

For the production of lump lime four

identical rotary lime kilns are under

operation.

Topic:

Dimensioning and design of the fans

under consideration of all other already

existing unit components and including

supply, installation, commissioning, test

run, and training of the operating staff.

Realisation:

Draft, on site measurements, and

checking dimensional limitations to

delivery conditions. In order to reduce

the smoke gas emission the electrostatic

filter was converted into a baghouse filter

and an evaporation cooler was integrated

upstream. The fan was made in parts and

assembled on site. (Time saving of two

weeks).

Fan:

HRZK01, 428,000 m³/h
