4 Air blast cooler/radiator DK Luvata designs and manufactures air blast coolers and radiators for countless applications, ranging from water cooling of large diesel engines to chillers for air conditioning and waste incinerators. Each cooler is designed to meet specific cooling capacity and noise level requirements. Optimal sturdiness Specifically designed to meet the demanding requirements of a diesel or gas motor fluid cooler, DK components include optimal sturdiness and specifically designed fixing points, along with a wide variety of other available options developed to fulfill applications. Material combinations and corrosion protection are customized to suit the individual environment of many industrial sites around the globe. The basic DK model includes optimized ventilated axial sections, equipped with asynchronous rotor fan-motors, already meeting with the strict rules on energy efficiency set by the ErP 03/05 directives. Special fan-motors with electronic commutation (EC) control are available to meet customers specific needs. Up to 7 modules DK offers low noise levels and optimized energy efficiency, to maximize the environmental compatibility for this specific application. DK offers a wide choice of impeller diameters offered as standard along with a wide range of options, including up to 7 modules. DK cooler benefits: Pre-designed with simple ordering product codes Different sizes within each cooler type Wide capacity range available High cooling capacity Compact design Low sound level Different fan speeds Low energy consumption Different materials available Computer program COILS available for correct sizing Reduced lifetime cost of operation Securely covered in a protective plastic film for delivery Finned heat exchanger The standard design of the heat exchanger is made from copper tubes and aluminium fins, making it highly resistant to corrosion. The headers are provided with vent and drain nipples. The unique design of the side panel and leg/support brackets ensure improved sturdiness and stability, but also provide stable support for the coil and reduce shaking during operation. The coolers can be equipped with frequency drive equipment for continuous control of fan speed to optimize energy efficiency and cooling capacity. Upon request models can be equipped with non-standard coils and fan motors. Technical data DK Sizes: From 3 x 75 to x 3 mm Max working pressure: 0.6 MPa Test pressure: 0.8 MPa Max working temperature: 0 C Min working temperature: -0 C Power range: Up to 3MW at ambient temp. 35 C and water temp. 70/0 30 C. The DK cooler can be designed with up to 7 modules. 0

5 Fan unit 50 mm diameter fan units are equipped with direct driven axial fans together with squirrel cage motors. The motor can be up-graded to insulation class H. The voltage peak resistance can reach 00 V. The design for smaller fan sizes provides external rotor fan motors as an option. The motor design and internal corrosion class are effective against corrosion in high humidity environments. The standard design includes tropicalization of the stator and rotor. Frequency drive technology is available to connect the motor to the inverter. Electronically commutated technology is available for the external rotor motor (also 50-size), enabling the motors to be regulated at different speeds for changing environmental conditions. This type of motor allows an extra power consumption decrease which is positive for the power plant installation. The fan is balanced according to ISO- 90/. Motors supplied with protection class IP 55 and F-insulation are delivered with open drain holes. The fans are also available in different speeds depending on the capacity and the acoustic requirements. Casing The standard casing of the heat exchanger is made of painted galvanized steel, RAL 900. If desired the unit can be painted in other colors for aesthetic reasons or specialty coated for corrosion protection.
