experience, Grundos technology is among the most

advanced and comprises solutions or every conceivable

challenge within:

Whether your system operates above or below zero and

whatever is running through the pipes, we have got the

solution to match your exact requirements.

Energy-eiciency is and always has been a strong ocus

in our R&D departments. For very good reason. I you

consider the lie cycle costs o a rerigeration, cooling or

heating system, the operating costs are much more

signiicant than the initial investment costs. In response

to this Grundos pumps are available with motors

characterised by a high level o eiciency combined with

low energy consumption. Our Grundos Bluelux label

guarantees that, as a minimum, the motors live up to the

eiciency requirements o tomorrow.

q e-

Grundos E-solutions programme oers numerous

possibilities o increasing eiciency. An array o motors,

speed controls and monitors have been speciically

designed to reduce the energy consumption o the

entire system without compromising perormance

in any way. Naturally, the E-solutions already as a

minimum comply with the uture EU-directives on

energy consumption and many even exceed them.

Every pump solution in the temperature control

portolio can be easily customised to match speciic

applications and individual requirements. Experienced

specialists are always on hand to assist you beore,

during and ater the development process. Just like

you, they are committed to optimising your speciic

project to improve competitive parameters.

If you wish to optimise a refrigeration application, Grundfos is

the ideal supplier to turn to. Decades of experience allow us to

offer highly efficient solutions for a variety of refrigerants and

secondary fluids, including:

> 744 (c2, cb x)

> 717 (h3, )> hFc (hyb)

> B

> y

Regardless of the fluid used, cooling below the ambient

temperature is conducted with great emphasis on reliability

and safety. The Grundfos range is capable of handling

temperatures down to -55 C, making sure that significant

deviations from a set temperature never occur.

py

Grundfos is the first manufacturer in the world to offer a 100%

dedicated refrigerant pump designed for the most frequently

used refrigerants and optimised for the use of CO2. While being

one of the most challenging refrigerants CO2

is becoming

increasingly popular due to its excellent heat transfer properties

and environmental friendliness. Built from scratch, the RC pump

accommodates the challenge of the high pressure, low viscosity

refrigerant while focusing also on the energy-efficiency. The

improved performance of the pump, in fact, enables savings in

pump energy consumption of up to 70% compared to traditional

solutions.

y

On top of our extensive line of high-quality pumps for primary

refrigerants, Grundfos also offers a dedicated range of pumps

for secondary fluids. Naturally, all refrigeration solutions can

be customised to match individual requirements.

Grundfos range of coolant pumps are suitable for virtually all

larger applications where cooling is an essential part of the

process, including:

> c w> p

> W b

> c

> e

> m

Grundfos standard pumps effortlessly circulate liquids in

temperatures down to -20 C. Temperatures below that must

be handled more carefully to avoid material stress in the pump

construction. To accommodate this challenge, special material

choices are available to allow for optimum operation in systems

with liquid temperatures as low as -40 C.

ey-v

In addition to the standard coolant pump range, a selection of

E-solutions is available if you wish to take energy-efficiency

and control to the next level. The integrated frequency

converter automatically adjusts the pump speed to make sure

that it only runs when required. This significantly reduces the

energy-consumption of a system and subsequently benefits

the environment as well as your customers bottom line.

F

The pumps shaft seal is one of the most important aspects

to consider in a cooling system. Refrigerants like ammonia are

hard on the seal and must be handled accordingly. Grundfos

offers various rubber types designed specifically to withstand

different media and to ensure that crystallisation does not

damage the seal. In open systems like wind turbines a leak-free

pump like the MAGdrive is a safe choice to ensure that

contamination is efficiently prevented.

A pump audit is the most effective way to discover

whether or not a pump system is operating optimally

and how you or your customer can potentially

save money and reduce CO2

emissions. Initially, a

comprehensive on-site inspection of the system will

pinpoint the areas that require optimisation.

Test data related to pump operation temperatures,

pressures and levels form the basis of the eff iciency

diagnosis. Finally, Grundfos offers recommendations

as to how process optimisations can be carried out to

your benefit and to that of the environment.

The ability to pump even very hot liquids with great reliability

is crucial in numerous industrial productions, e.g.:

> F w

Grundfos range includes pumps designed to efficiently

circulate hot water as well as thermal oil and to offer safe,

uninterrupted operation.

v y w

Particularly thermal oil requires careful attention as liquid

temperatures may reach 240 C or more. No shaft seal can

tolerate temperatures that high for longer periods, which is

why Grundfos has developed the CRN air-cooled top. By

separating the pumped liquid from the shaft seal, overheating

is efficiently prevented as is costly downtime.

Grundfos pump units are based on modular design and are easily

customised to suit a variety of heating applications. Specifically

for integrated systems a range of compact pumps are available.

E-pumps with integrated frequency converter offer a superb

array of pump-related functionality that will benefit most

systems in terms of comfort, user-friendliness, process

adaptability and not least operating economy. By regulating

pump speed according to demand, energy consumption and

operating costs are significantly reduced. Compared to

conventional fixed-speed pump solutions, E-solutions enable

annual energy savings up 50%.

Additional benefits of E-solutions are:

> c temperature is kept constant

irrespective of the flow.

> ensures optimum tolerance of

ambient temperatures.

> - ensures reliable and precise response

to parameter regulations.

> heats up the motor during standstill to

avoid damaging condensation.

> c w c y

> Fw pump, motor and converter are built

into one to make installation, maintenance and service

much easier.

Naturally, Grundfos E-solutions can be customised to meet

specific requirements. Pump curves can be stretched, extra

functions can be added and special operating panels can be

included to mention but a few of the options. So if standard

optimisation just isnt enough, please contact us for dedicated

solutions.

A specific range of sensors is available

for use in connection with E-pumps.

This includes temperature sensors and

differential temperature sensors,

pressure sensors, differential sensors

and vortex flow sensors.

The intelligent CR monitor reduces

costly downtime to an absolute minimum

through constant monitoring and

supervision of critical parameters in a

process. In case of deviations, an alarm

is issued which allows problems to be

rectified long before they potentially

cause breakdown. Specifically designed

and preconfigured for the CR pump,

the monitor also enables ongoing

optimisation of the pump in terms of

efficiency and power consumption.

cIm/cI

Offering ease of installation and great

value for money, Grundfos CIM/CIU

communication interfaces are the

obvious choice when you want complete

control of your E-pumps or pump

systems by connecting them to your

SCADA system. Both interfaces support

most fieldbus standards.
