DKK High Pressure Reciprocating Series

DKK High Pressure Reciprocating Series Air Compressors

DKK 40 / DKKB 40 / DKKB 40A

 

DALGAKIRAN, manufactured its first reciprocating air compressor in 1965, promises suitable, trouble-free and high performance for every kind of application with its DKK series high pressure reciprocating air compressors. Manufacturing and assembly of every single part of these compressors, in which latest engineering softwares are used during design and analysis phases, are realized considering international quality standards.

 

DALGAKIRAN proudly presents its DKK series high pressure reciprocating air compressors developed for all applications where high pressure is a must, especially for the maritime sector where DALGAKIRAN has been interested in and has served meticulously since its establishment.

 

LONG LIFECYCLE

Cast-iron crankcase and cylinders, pistons operated at low-speed, corrosion and heat-resistant stainless steel valves, cylinders and bare pumps with cooling fins make DALGAKIRAN DKK series high pressure reciprocating air compressors durable along their lifecycles.

 

EASE OF USE

DKK series high pressure reciprocating air compressors are manufactured to be employed different areas of application without any performance loss. The parts with high performance and quality grades, that are used in manufacturing and assembly of the products designed to make users in every level of experience easily adapt and learn the control, provide long maintenance periods and thus, low operating costs as a result.

WIDESPREAD AFTER-SALES SUPPORT SERVICE

As having operations in more than 100 countries around the globe and possessing more than 150 authorized dealers in Turkey, DALGAKIRAN offers reliable use of the products to its customers with its after-sales support network.

 

COMPRESSOR BLOCK

• Heavy-duty type cast-iron crankcases contain oil level indicators properly placed on crankcase, blowdown valve and oil filling/draining plugs.
• Cast-iron cylinders and bare pumps with cooling fins help the system preventing overheat.
• Dynamically balanced and precisely manufactured cast-steel crankshafts and counter weights prolong the lifecycle of the compressor.
• Lightweight pistons casted from special aluminum alloy and cast-steel connecting rods, which are suitable for Lloyd certification, not only apply less pressure to crankshaft but also help the compressor run even in most challenging environments along with high heat transfer capability.
• While specially designed finger-type high capacity stainless steel inlet-outlet valves at the first stage provide the high capacity air flow, the inlet-outlet valves at second stage, specially designed for high pressure conditions, guarantees to keep the bare pumps at optimum operating temperature by maximizing the airflow rate.
• Compression and oil retaining rings are used for holding the airflow maximized and preventing oil leakages.

 

MAIN MOTOR AND DRIVE SYSTEM

• High efficiency IE2 class IP55 motors are used as a standard in DKK series.
• Driving the rotor shaft is realized by a belt-pulley mechanism placed between rotary screw block and main motor and selected considering a suitable transmission ratio.
• Belts are chosen by considering the working life of minimum 25,000 hours.
• The pulley with bushing eases assembly-disassembly processes.
• With easy adjustment of belt tension, continuously efficient operation of the compressor is secured.
• Special loadless operation system lengthens the lifecycle of the main motor and the compressor block.
