To the type of the cargo that is to be transported in the vehicle (Frozen or fresh food),

To the conditions of geographical area where the vehicle will generally run,

To the type of distribution (Inner-city/outside city),

To the number of opening and closing car doors during a day,

To the type and quality of vehicle isolation,

To whether the vehicle has air curtain,

Refrigerating devices are designed only to save the temperature of cold products. It is not possible to refrigerate or freeze the products in exterior temperature by using these devices.

Unit should not be run while loading as running unit makes the entrance of exterior temperature (temperature and humidity) easier to inside the case.

ATP Certificate is obligatory for international refrigerating cargo in Europe. (It will be also obligatory in our country in the near future.)

ATP Certificate is your guarantee when you are carrying a refrigerating cargo. 

ATP Certificate increases value of your refrigerating vehicle. 

ATP Certificate increases quality standards of your business. 

It is not possible to carry cargo of foods, etc. in ATP member countries. 

Vehicle that does not have ATP Certificate is disqualified from driving in ATP member countries. 

Cargo is transferred to the vehicle having ATP Certificate and high penalty is paid to the vehicle that does not have ATP Certificate. 

This Certificate is for 6 years. Temperature ranges for transportation in accordance with FRC Certificate are determined. It is necessary to make control and revise the standard.

Operating voltage

Operating voltage of air conditioning for rail systems is 380 VAC / 3 FAZ / 50 Hz. However, the existing voltages in the vehicles are 750 VDC, 1000 VDC and 1500 VDC, which are received from third rail or catenary. Therefore, it is necessary to generate stabile supply voltage by providing required voltage alternation with the inverter + chopper system that are used. 

Air conditioning units for rail systems are implemented to the wagons of light rail underground railways, street trolley cars, EMU, DMU, suburban line trains (sleeping and dining cars), underground railways and high-speed trains.

Air conditioning units for rail systems can provide for all ranges depending on the increase of ∆T temperature difference capacity. However, in case that there is no extra demands, by taking EN 14750 – 1 ve EN 14813 – 1  standard which is determined for both passenger air conditioning unit and driver cabin air conditioning unit as a basis, and on condition that it is complied with temperature regulation curve, and that no damage is given to human health, the design is developed to reach 6-8 °C temperature difference. 

International railway industry standard IRIS becomes a compulsory document for railway biddings in Turkey just as it is in abroad; it was published in the the 6c clause of 27628 numbered official gazette and entered into force on July 1, 2010. In accordance with this Regulation, as it is specified in the article 6c with regard to “TECHNICAL ACCEPTANCE OF FREIGHT CAR AND WAGON MAJOR COMPONENTS”, “the copy of original document or institution-approved document of ISO 9001 or IRIS quality management system certificate” is demanded by the General Directorate of Turkish State Railways as an official document required for bidding.

In the European Union accession process, international companies and operational institutions demand IRIS Quality Management Certificate from sub-suppliers and producers as a compulsory client requirement for their biddings. Through the development process, companies that do not have this Certificate cannot sell their products to the main railway producers and participate to the biddings in the very near future.

Our devices are appropriate for military vehicles such as shelter, tank, howitzer, ammunition carrier, armored vehicles, etc.

Military vehicles are produced in accordance with the testing procedures specified in MIL-STD-810G.

It is the standard that is prepared by USA Defense Ministry; environmental testing method constitutes its content.

Our products in military standards are tested according to the designated procedures of environment condition tests below:

High temperature tests

Low temperature tests

Solar radiation test

Sprinkler test

Humidity test

Salt test

Sand-dust test

Vibration test

Shock test

EMI/RFI test

Some tests are performed by the companies such as Aselsan, MKE, Concept, etc. operating in Turkey while some tests can be only made in the accredited laboratories in abroad. 

It is the product that is approved by TSK (Turkish Armed Forces) and has a NATO account code. Our ES 256 / AS and ES 356 / AS devices are displayed in the website of TSK.

Region where the vehicle will run,

Number of passengers transported by the vehicle,

Vehicle type (coach or municipality car),

Ceiling type of the vehicle,

Channel structure,

Engine specifications of the vehicle,

Crankshaft pulley caliber 

FRP for cabin, ASA + ABS for outer covers, aluminum for plate materials, copper tube for junctures placed within the vehicle are preferred. 

Air conditioning part for drivers can be optionally provided by placing cooling fin within the vehicle radiator box and by using the condenser of ceiling type in common. 

Heating option is provided through the circulation of vehicle engine water in the system. 

Except special designs (actuating current from diesel engine or electrical air conditioners), all air conditioners run through actuating current of the compressor in the vehicle engine part from vehicle engine. 

R134a cooling medium for air conditioners of bus, midibus, minibus, R407C cooling medium for our rail system air conditioner implementations, R134a or R407C cooling medium for the project with military purpose, R404A cooling medium for refrigerating devices are generally used.
