Automotive Spare Parts & Cars Maintenance Services

Years of experience and perspective

KALE Oto Radyatör A.Ş. was established in Istanbul in 1966. The small-scale production which started with engine cooling and heating radiators for automobiles increased after 1980s rapidly. The company has become the leader producer in Turkey in its area of specialization.

KALE, has been offering its services to variety of OEM customers with its wide range of products. The company has been supplying products to the personal car producers, agricultural machine and equipment producers, industrial machine and equipotent producers within the stated group.

KALE’s growth in production was significant in 1980s in parallel with both the growth in Turkish Automotive Industry and developments in export and spare parts markets.  In 1985, KALE established a new and modern production facility with a total indoor area of 20,000 m2 and 60,000 m2 industry area in Çayırova-GEBZE region which is at the 55 km Southeast of Istanbul to respond to the increasing business volume and request increase.

In 1994, KALE added 5000 m2 indoor area to its production facility in Çayırova to activate the new manufacturing technology called as “Aluminum Brazing (CAB)”.

Today KALE has been rendering its services to Turkish Automotive Industry, spare parts and export markets with its factory based in Çayırova with total 600 employees including experienced engineers and the production team. The company has been offering wide range of products covering engine cooling radiators, heating radiators, condenser, intercooler (Air conditioning radiators), oil coolers, complete engine cooling modules, HVAC ( Heating-Ventilation and Air Conditioning) systems, complete air conditioning systems to the mentioned customer groups.

KALE Products


The system which includes assembly of many components used as complete system cooler and sub products in a car is called Cooling Module.

Cooling modules consist by assembling radiator, intercooler, oil cooler, condenser, expansion tank and fan&air-condition group.

Cooling modules are especially adopted by automotive main industry companies because they add value to the flows of the vehicle montage lines thanks to fast connection and direct integration.


Radiator which is placed in the engine cooling system in the vehicles is the most functional element used in dissemination of extra heat to the atmosphere. It is necessary to maintain extra heat generated during the operation and ensure optimum structure heat in conventional engines and new generation electric engine/battery systems. 

During the flow of cooling liquid through the tubes in the radiator, pressure air is passed over the radiator fins by a fan, and thus heat transfer is ensured. Therefore, cooling liquid which reaches to the radiator in high heat from the engine block returns to the engine block by cooling in the radiator. In the end, engine block heat value is maintained in the proper operation range. 


It is one of the most important parts of intercooler system to increase vehicle performance and generate more power. High temperature air disseminated from turbo in turboengine vehicles is cooled till a specific temperature and it is transferred to the absorbing manifold. This way increase of volumetric efficiency is ensured, and oxygen increases in the air in unit volume.

 Cooling in intercooler is secured by the tubes cycling maximum level of warm air thanks to their special form turbulence structure and heat transfer of outdoor air through fins by the support of fan. Intercooler assuring the increase of traction and compliance of exhaust resulting from full combustion to the environmental values is a heat exchanger which accomplishes an important mission in the system. 


Condenser which is a part of the vehicle air conditioning system is a heat exchanger which converts cooler liquid from gas form to liquid form. It is located in the front part of the vehicle in the full cooling module with the other coolers. It is necessary that condenser be cooled with fan air because of required condensation resulting from dissemination of heat from the cooling liquid in A/C system. Cooling liquid with increased pressure and heat upon being compressed by the compressor in the system is transmitted to the condenser. Cooling gas condensates by transmitting its heat to outside in the radiator which consists of extrude tubes and fins in the condenser and it exits the condenser in liquid phase.

KALE Condenser design is being optimized to meet OEM standards as part of the A / C system and taking into account the technical requirements of other refrigerants in the system. Thermal performance, air and liquid side pressure loss tests are conducted in integrated calorimeter unit and high corrosion resistance and high pressure operating performance are measured in our test laboratory. Then product approvals are given. All of the produced condensers are subject to 100% Helium test and shipped after being checked.

Heater Core

The heater generally located in HVAC unit is a radiator which has a function in generating hot air to be transmitted to the vehicle cabin. 

The hot fluid received from the thermal system enters into the radiator and heat transmission occurs while it passes through radiator. The air received from the blower unit in HVAC cabin warms upon the contact with radiator synchronic and hot air is steered into the vehicle.


Fan & Motor & Shroud

The air-conditioning group which consist of air-conditioner, electric motor and fan placed in the front part of the vehicle ensures transmission of outdoor air to the engine water cooling radiator, intercooler and A/C condenser by the fan wings. 

The fan triggered by the electric motor pass the air over the radiator consisting of tubes and fins affects the heat transfer between air and cooling liquids and functioning of the coolers.




Compressor, one of the main parts of the A/C system, generally is triggered by belt, pulley mechanism of the engine shaft in vehicles. When the A/C system operates, the compressor liquefies the fluid gas transmitting it to the condenser at high pressure and temperature. The compressor is necessary to absorb the cooling gas disseminated from the evaporator in gas form with low pressure, liquefy it with pistons and transfer it to the condenser with increased heat and pressure. The input to the compressor occurs in the gas phase, the heat of the gas entering at low temperature with low-pressure increases with the increase in cooling liquid pressure and it disseminates the compressor in gas form again. If the A/C system cooler pressure is not increased by its compression in compressor, conversion from gas form to liquid is not possible in the condenser and cooling process cannot occur due to lack of heat absorption in evaporator.
