What Kind of Antifreeze is Better

Dec. 31, 2021

When the diesel engine runs under the necessary environment conditions of less than 0℃, beware of cooling water freezing to prevent parts from breaking.  Therefore, when the diesel engine stops running, the cooling water is discharged.  The type of generator set with closed cycle reciprocating refrigeration system can be adjusted according to the minimum working temperature of each place to the appropriate freezing point of the anti-cold refrigerant, the general refrigerant has glycol plus water and alcohol, glycerin plus water two categories, for your reference.

Antifreeze is a kind of coolant, the main success is: calcium chloride, formaldehyde, ethanol, ethylene glycol, glycerin, which contains a special additive, with winter antifreeze, summer anti-boiling, year-round anti-scale effect.  Antifreeze is widely used in liquid-cooled engine cooling system.  

 

It is recommended to use ethanol type low-silicate antifreeze that meets the REQUIREMENTS of American GM6038-M standard (the content of silicate, oxide and acetic acid in antifreeze is not higher than 1000PPM, 5PPM and 100PPM respectively) as antifreeze of diesel engines.  

 

When selecting antifreeze, antifreeze should be selected at a freezing point about 10 deG C lower than the lowest temperature in the area.  

 

Note recommendation:  

 

1. The storage time of antifreeze before use shall not exceed two years;  

2, do not allow the use of anti-freeze agent agent, so as not to affect the normal operation of the diesel engine with water filter;  

3. When antifreeze is used in the cooling system of diesel engine, the concentration of DCA4 or DCA4+ additive in the coolant shall not exceed 2 units of additive per gallon of engine coolant (1 gallon =3.785 liters);  

4, when the antifreeze contains DCA4 chemical additives approved by Volvo Engine Company, antifreeze replacement cycle.  Antifreeze containing additives such as anti-corrosion and cavitation additives that are not approved by Volvo Engine Company is not recommended;  

5, DCA4 and DCA4+ additive content is slightly different, but can be used interchangeably.  

 

The configuration of Volvo generator set will include the "four protection" system. When the temperature is too high, the shutdown alarm will occur, and users can pay attention to the problem and the root cause of the problem in time to deal with it.  VOLVO series environmental protection units, emissions meet the EU 2 or 3 and EPA environmental standards, the group's VOLVOPENTA focus on power generation, special diesel generator sets and Marine diesel engine production, it in six cylinder engines and electronic injection and other aspects of the technology ahead of the rest.
