Quickly to your goal: The new 3D-CAD library is live

With the new 3D-CAD library, KTR makes access to technical drawings easier than ever before. Access is directly via the KTR website -
without external platforms or additional registration. The state-of-the-art user interface is intuitive to use allowing to find the requested CAD
data with just a few clicks.
Thanks to the integrated material numbers retrieval and high-performance filter functions, products can be found even more specifically. The
selection is additionally facilitated by relevant supplemental information that is directly displayed in the CAD selection.
The CAD data is available in the common 3D formats STEP AP203, STEP AP214 and IGES. Besides, for selected data records 2D-PDF
files are available - ideal for fast processing in designing.

Combined coolers type MMC
Cooling systems

Structure
The MMC cooler is a high-performance cooler made of aluminium. It combines several cooling circuits, for example for charge air, water
and oil in one single system. The design of the cooler is specifically suitable for heavy duty applications. The laminas are selected based
on thermal and hydraulic parameters. The depth of the cooler cores may vary between 32 mm and 200 mm. The cooler dimensions are
specifically adapted to the respective mounting space. Here sizes up to 2000 mm are feasible. The selection of the fan is based on the
requirements calculated such as mass flow, noise generation, speeds, etc. When designing the drive there is the option to select between
a direct fan drive, an electric motor adapted to the operating parameters or a hydro motor.

Manufacturing expertise in our own plant

Our new cooler production plant in Jiaxing located

100 kilometers southwest of Shanghai com-
menced operations at the end of 2018. On an
effective area of about 9,000 m2 we manufacture
high-quality cooling systems for the global market
being used as multimedium coolers in construc-
tion and agricultural machinery or as oil/air coolers
in stationary hydraulics.

For that purpose we invested in a state-of-the-

art machinery park. Joachim Grunwald, Product
Manager of MMC combined coolers: „We are in
a position to manufacture smaller quantities with
a high level of automation and consequently at a
constantly high quality level here." There is a very
close cooperation between the manufacturing
specialists in Jiaxing and the design engineers
and project managers in Rheine. Since the team
of engineers at KTR's headquarters in Rheine/
Germany is and remains responsible for the de-
velopment of the cooling systems.

Weycor wheel loader AR530 by Atlas Weyhausen

The wheel loader is one of the medium size types of the portfolio equipped with a
water-cooled 4-cylinder DEUTZ engine series TCD 3.6 L4 High Torque with a 3.6 litres
displacement and a maximum power of 55 kW.

KTR was commissioned with the selection of the cooling system. For cooling charge air,
cooling water and hydraulics a triple-circuit combined cooler type MMC is used.

Open Power Unit by Hatz

The diesel engine manufacturer located in Lower Bavaria provides all variants of the new
H series as a pre-finished open power unit. The standard model, the water-cooled 4-cylinder
4H50TIC with 2 litres displacement and a maximum power of 55 kW counts on common
rail technology, turbo loader and external exhaust gas recirculation.

For cooling charge air and engine cooling water a dual-circuit combined cooler type MMC
by KTR which was dimensioned in cooperation with Hatz is used. In addition the scope of
delivery comprises a compact oil cooler installed at the engine side cooling the engine oil
via the engine cooling water.

Selection system
To select the suitable cooler you need to know the following details:
Q [kW] Heat to be dissipated
V [l/min] Oil flow
Toil [°C] Inlet temperature of oil into cooler
TL [°C] Inlet temperature of ambient air into cooler

Example of calculation Performance diagramme of OAC400

Details given:
Q = 12 kW

kW/K
V = 75 l/min
Toil = 65 °C
TL= 30 °C

Voil [l/min]

Calculation of specific cooling capacity

Difference of inlet temperature ETD [°C] = Toil - TL
Specific cooling capacity required Prequ. = Q/ETD
The specific cooling capacity required must fall below the performance curve!  12 kW/(65 °C - 30 °C)= 0.34 kW/°C
The following was selected: OAC400
The actual cooling capacity of the cooler is 0.39 kW/°C x 35 °C = 13.65 kW

Calculation of pressure loss

The pressure loss in the curves of the different data sheets is based on a viscosity of 30 cSt.
The effective pressure loss is calculated as follows:
Pressure loss (from curve) x factor = effective pressure loss

Example Pressure loss 30 cSt

Voil: 75 l/min
Viscosity: 20 cSt
Pressure loss [bar]

 0.31 bar x 0.75 = 0.233 bar

Cooling systems

Cooler accessories

Pressure bypass (DB6 & DB6F)

The pressure bypass protects the cooler core against excess pressure. A share of the volume flow is bypassed along the cooler core
depending on the opening pressure.

Thermal & pressure bypass (TB6)

The thermal and pressure bypass additionally provides for faster return of the oil passing the cooler core to efficiently reach the operating
temperature through the load. Safeguarding the pressure is assured in parallel.

Integrated bypass (DBI6 oder TBI6)

The integrated pressure (DBI6) or thermal & pressure bypass (TBI6) operates in the same way as mentioned above, but the bypass duct
is completely integrated into the cooling element and therefore does not represent an interfering contour to the standard.

Assembly
With assembly and disassembly of the oil connection lines, hold up with a hexagon key (max. tightening torque 40 Nm). No reduction of the
cross section behind the cooler. Return filters to be installed in front of the cooler (dynamic pressure, danger of bursting). Tensions inside
the connection pipes have to be avoided! Vibration of the piping must be avoided (should possibly be intercepted in front of the connector).
Supply and discharge to be chosen alternatively. Please note that not a few hydraulic systems generate pressure peaks of more than 12
bars in the return flow (danger of bursting)! Please observe our assembly instructions at www.ktr.com.

For PIK sizes 200 and 350 specify the IEC motor sizes in your order.

Cooling systems

High power density in a tight space

Technical data
Plate heat exchanger made of stainless steel 1.4401 soldered with copper. The stamped plates generate a high power density in a tight
space. Compared to a tube bundle heat exchanger, the plate heat exchanger only requires approx. 25 % - 30 % of mounting space with
less weight. Applications are, as an example, machine tools, test benches, injection moulding machines, pump units, waste heat utilization,
etc. It is possible to use other media like, for example, oil, water glycol, water, refrigerating agents, air, etc.

Operating temperature: -10 °C to +200 °C.

Please observe boiling point and freezing point!

Oil-water cooler TAK/TP
Cooling systems

Cooling of lubricating oil, heat recovery

The TAK/TP cooler ranges were originally designed for hydraulic systems, but based on their design they are equally suitable for cooling
lubricating oils, heat recovery, etc.
The tube bundle is designed in that it may expand to both sides. Thermal stresses are consequently minimized.
The unique tube-to-tube plate joint ensures high reliability.

Materials used:

These coolers are available in both industrial and marine versions. (Tube bundles made of stainless steel on request)

Industrial version (standard)

Tubes Brass (EN CW614N)
Tube retainer Brass
Housing Aluminium
Headers Brass (EN CW614N)
Gaskets Nitrile

Marine version
Tubes 90/10 copper/nickel
