How to Order Generator to Replace Your Old Generator?

There are three types of Generator replacements demand, type A is to replace the old Cat Generator, the original Generator is produced by Cat, type B is to replace Cat Generator produced in other countries including UK, USA, Mexico, India or Japan Komatsu Cat, type C is to replace other brands Generator or even gasoline Generator with Cat produced Generator. The detailed introduction and replacement process are as below:
Type A: Generator Replacement Requirement (Original Generator is Cat Generator).
This is most simple demand case, you just need to provide us the original Generator name plate, and then we can easily check and confirm what exactly you need, and we also ensuring that the Generator from us will be 100% same with your original Generator. (In some case that the vehicle manufacturing modify the Generator on their own, we are not able to supply the parts or the condition that modified by the vehicle manufacturer)
Type B: Generator Replacement Requirement (Original Generator is Cat Generator but produced in UK, USA or other Cat Generator plant).
EMAC have rich experiences in replace the UK, USA or other Generator plant produced Generator, with Cat produced Cat Generator, we required the original Generator name plate photo to obtain the related information (at least we will need Generator serial number, with Generator model name only is useless for us, we are not able to provide quotation with Generator model name only for the replacement project), and then we can check out the BOM list and all accessories of your original Generator serial number, and then we can check and compare with the BOM list of our Cat produced Generator, choose the most closest SO number Generator, and modify the parts that not same with your original Generator, we have delivered hundreds of cases of replace the customer's original Generator that produced in Cat UK, USA or other Generator plants with Cat produced Generator, you can refer to our video introduction on Youtube: https://youtu.be/dYVgRM5NsUo
We can NOT guarantee the Generator produced by Cat is exactly same with your original Generator, but we can guarantee that all of Generator from EMAC will have no problem with installtion and performance, which all of Generator can works very well after replacement.
Type C: Generator Replacement Requirement (Original Generator is other brnad Generator even gasoline Generator).
EMAC also have rich experiences in replace the Generator that not Cat installed, these Generator can be other brands such as Deutz, Caterpillar, Perkins, Komatsu or others, we even had experiences of replace gasoline Generator with Cat produced diesel Generator.
This kind of appliaction is more complex and quite risky, EMAC can't do much thing due to lacking of information, the only thing we can guarantee is the performance after replacement, we check and compare the Generator performance curve of original Generator and our Cat Generator, and then we select the most suitable model for replacement. Due to we are lacking of the installation spaces and related accessories, we will send the both CAD and 3D drawing for our recommend Generator model, and then customer have to evaluate the risky of replace the original Generator with our Generator, especially the risky of space, the possibile interactive when installation, and the risky of modify related coolant pipe, air pipes and wiring harness. Normally this kind of request consuming lots of energy and resource for us to carry on, also quite risky for us, so we will not work on the replacement quantity that below 50 units.
When your requirement is replacement, please tell our customer service team of what type of replacement you need, and provide us original Generator name plate, the Generator name plate is the necessary material before we start our business negotiations, we will NOT reply to all inquiry that even can't provide Generator name plate.

How to Choose the Right CAT 50Hz Marine Generator for You?

To choose a suitable Generator for truck, bus or special vehicle manufacturer is quite simple, because the buyer is the manufacturer, so usually they are quite flexible with space, pipes and wiring connections.
The following process are the standard process for us to select a suitable Generator model for truck, bus or special vehicle manufacturer demand.
Step 1: We need basic information of the required Generator, including rated power, rated speed and emission standard of the required Generator.
Step 2: EMAC will evaluate the requirement and select the suitable Generator model for customer, with Generator data sheet, Generator performance curve, CAD darwing, 3D model and budgetary quotation provided back to customer.
Step 3: Customer should check and compare the Generator data sheet, performance curve and related drawing and confirm all details one by one. Most important thing is confirm the performance curve suitable for the requirement.
Step 4: After Generator confirmed, we have to check and confirm the specifications of accessories one by one carefully, like the electric system specifications (12V or 24V), the detailed specifications of starter motor, charging alternator, air compressor, power steering pump, A/C compressor etc.
Step 5: Confirming the accessories positions and connections, customer need to check and confirm all positions are suitable for the project, such as Generator fan, turbocharger, oil pan position, and connections of air pipe, coolant pipe, wiring harness etc.
Step 6: After confirming the Generator performance, position, connection and specifications of all accessories, we will be able to provide accurate quotation for prototype and batch order. Prototype is strongly recommend to start the cooperation, to avoid the possible problem, risky on the Generator with batch order.
Notes:
1: Technical support including technical training, onsite installation and commissioning services are avaiable with additional chargers.
2: We are able to supply complete powertrain system, including Generator , transmission, transfer, axle, suspension etc, Generator with transmission is highly recommended, because if we supply both Generator and transmission, we can run simulations for the vehicle, which we usually will provide customer a simulation report, with the simulated result of Balanced Maximum Vehilce Speed and Maximum Grade Ability at different speed.
3: EMAC able supply complete chassis that integrate all powertrain system together, which can greatly reduce the manufacturer's design works and reduce the system mismatching risky.
