Tips:When temperature and pressure of cooling water are abnormal.
No. Malfaunction and causes Remedy 1 There is air in the water pipe, which results no or little water from the outlet water pipe when the engine is working and causes high temperature of water. Loosen the joint of termometer on the outlet pipe, exhaust the air until the water canflow fluently, then tighten all the joints of the water pipelines. 2 Low pressure of cooling water:
(1)Low water level
(2)Block of cylinder water heat exchanger or radiator
(3)The air enters the system from cylinder water pump suction point
(4)The pressure cap is damaged or incorrect
(5)The pressure meter isn’t accurate.
(6)The line of pressure meter is blocked or the valve is closed
(7)The leak of water pump seal
(8)The water-cooled exhaust manifold gasket is burned
(9)The water-cooled exhaust manifold gasket is broken(1)Add coolant
(2)Clean or replace
(3)Repair the leakage, remove the air from the system
(4)Adjust or replace
(5)Compare with the main meter, change the meter
(6)Change the line, open the valve
(7)Repair the water pump
(8)Replace the gas
(9)Replace the manifold gasket.3 Low temperature of cylinder water:
(1) The pressure meter isn’t accurate
(2) Fault with thermostat(1)Compare with the main meter, change the meter
(2)Replace the thermostat4 High temperature of cylinder water:
(1) The pressure meter isn’t accurate.
(2) Fault with thermostat
(3) There is leakage in the cooling system
(4) Bad coolant cycle
(5) Aging of cylinder water pump or the bad effect of sealing
(6) Solidification of coolant
(7) Combustion of flammable tube
(8) Late ignition time
(9) Cracked cylinder head
(10)The cylinder is broken(1)Lower down the temperature of engine slowly,compare to the main meter and then adjust
(2)Replace
(3)Remove air from the cooling system
(4)Find the reason for overload then correct check the whole cooling system
(5)Replace or repair the water pump
(6)Unfreeze the whole cooling system before starting the machine
(7)Change the flammable head
(8)Retiming the ignition
(9)Change the cylinder head
(10)Change the cylinder

27 KVA Standby Diesel Generator with CE and ISO verified
When I work with customers on backup power planning, I always start from a simple reality: electricity failure never gives warning. It just happens. That’s why a small but stable system like the 27 KVA standby diesel generator with CE and ISO verified is often the most practical solution for many businesses.
At Camda New Energy Equipment Co. Ltd., we don’t treat generators as simple machines. I see them more like a safety layer for business operations—quiet when everything is fine, but absolutely critical when things go wrong.
This 27 KVA diesel generator is designed for standby use. It stays idle during normal grid power and automatically starts when electricity fails. The CE and ISO verification ensures that the system follows international safety and manufacturing standards.
I usually explain it in simple terms: it’s like a backup worker who never sleeps, always ready to step in when needed.
| Specification | Value | Source |
|---|---|---|
| Rated Power | 27 KVA / approx. 22 kW | ISO 8528 Generator Standard |
| Certification | CE / ISO Verified | SGS Certification Report |
| Start Time | 5–10 seconds (ATS system) | Schneider ATS Technical Guide |
Inside the generator system, there are three main parts: diesel engine, alternator, and controller. I always explain it in a way that even non-technical users can understand.
Engine = produces mechanical energy
Alternator = converts energy into electricity
Controller = manages start, stop, and protection

When power outage happens, the automatic transfer switch (ATS) detects it immediately and starts the generator within seconds. The load is transferred smoothly without manual operation.
| Component | Function | Reference |
|---|---|---|
| Cummins Diesel Engine | Mechanical power generation | Cummins Technical Manual |
| Brushless Alternator | Stable electricity output | IEC 60034 Standard |
| Smart Controller | Monitoring & protection system | Deep Sea Electronics Guide |
From real-world installations, I notice customers care most about reliability, fuel efficiency, fast response, and low maintenance. This generator is designed exactly around those needs.
Automatic start with ATS system
Stable voltage output under load changes
Fuel-efficient Cummins-powered engine system
Compact structure for easy installation
Optional silent enclosure for low noise operation
| Feature | Benefit | Industry Standard |
|---|---|---|
| Automatic Start | Fast recovery during outages | IEC 60947 ATS Standard |
| Fuel Efficiency | Reduced operational cost | Cummins Performance Report |
| Noise Reduction Option | Suitable for urban areas | ISO 3744 Acoustic Standard |
At Camda, every generator is built as a complete system, not just assembled parts. We use globally recognized components to ensure stable long-term operation.
The Cummins Powered Diesel Generator platform is widely known for durability, fuel efficiency, and stable power output under continuous load conditions.
Before shipment, every unit undergoes load testing from 0% to 100% to ensure performance under real working conditions.
| Technical Element | Advantage | Source |
|---|---|---|
| Cummins Engine Technology | Long service life & stability | Cummins Global Datasheet |
| Brushless Alternator | Low maintenance operation | IEC 60034 Standard |
| Load Testing System | Verified real-world performance | ISO 8528 Testing Protocol |
The 27 KVA standby diesel generator is widely used in small to medium power demand environments where reliability matters more than size.
Small factories and workshops
Telecom base stations
Hospitals and clinics
Commercial buildings
Construction sites and temporary power supply
In many cases, even a few seconds of power loss can cause system failure or financial loss, so standby power is not optional—it is necessary.

From steel frame production to final testing, every step is controlled. I always believe quality is not something checked at the end—it is built into the process.
| Stage | Process | Standard |
|---|---|---|
| Frame Fabrication | Steel cutting and welding | ISO 9001 System |
| Assembly | Engine and alternator integration | Factory Inspection Process |
| Final Testing | Full load performance test | ISO 8528 Standard |
We also follow ISO14001 environmental management standards and OHSAS safety systems to ensure responsible and safe manufacturing practices.
From my experience, customers don’t just buy a generator—they buy confidence during unexpected power failure.
Camda has been manufacturing generator sets since 1998 and cooperates with global brands like Cummins, Perkins, Yuchai, Stamford, Leroy Somer, ABB, and Schneider. This gives us strong system integration capability and global reliability standards.
We also provide complete support including design, production, testing, packaging, shipping, and after-sales service.
Q1: How fast does the generator start?
Typically within 5–10 seconds after power failure using ATS system.
Q2: Is it suitable for continuous operation?
It is mainly designed for standby use, but can run extended hours with proper maintenance.
Q3: Does it include CE and ISO certification?
Yes, the product is CE certified and ISO verified by SGS inspection standards.
Q4: Is noise control available?
Yes, optional silent enclosure reduces noise significantly for urban environments.
Q5: What is the delivery time?
Normally 15–35 days depending on specifications and order quantity.

A standby generator is not something people notice every day, but when power fails, it becomes the most important system in operation.
The 27 KVA Standby Diesel Generator with CE and ISO verified is designed for that exact moment—fast response, stable output, and long-term reliability that businesses can depend on.
