Definition: Isolated explosion-proof mold temperature machine is a kind of mold temperature machine with explosion-proof function, its main feature is the use of isolation transformer inside the electrical equipment to isolate the power supply from the equipment, so as to reduce the risk of flammability and explosion of the equipment.
Features: Isolation transformer is used to realize the isolation of power supply and equipment
It has high safety performance and reduces the risk of flammability and explosion of the equipment
It is suitable for flammable and explosive environments, such as petroleum, chemical, pharmaceutical and other industries.
Application scenario: Isolated explosion-proof mold temperature machine is mainly used in occasions with high safety performance requirements, such as petroleum, chemical, pharmaceutical and other industries.
Definition: Positive pressure explosion-proof mold temperature machine is a kind of mold temperature machine with explosion-proof function, its main feature is the use of positive pressure protection device inside the equipment, by keeping the pressure in the equipment higher than the external pressure, to prevent flammable and explosive gases from entering the equipment, so as to reduce the risk of flammability and explosion of the equipment.
Features: Positive pressure protection device is used to keep the pressure inside the equipment higher than the external pressure;
It has high safety performance and reduces the risk of flammability and explosion of the equipment
It is suitable for flammable and explosive environments, such as petroleum, chemical, pharmaceutical and other industries.
Application scenario: Positive pressure explosion-proof mold temperature machine is mainly used in occasions with high safety performance requirements, such as petroleum, chemical, pharmaceutical and other industries.
In terms of safety: both have high safety performance, but the isolation explosion-proof mold temperature machine mainly realizes the isolation of the power supply and the equipment through the isolation transformer, while the positive pressure explosion-proof mold temperature machine keeps the pressure in the equipment higher than the external pressure through the positive pressure protection device. From the perspective of safety, the positive pressure explosion-proof mold temperature machine has higher safety performance than the isolated explosion-proof mold temperature machine.
Scope of application: Both are suitable for flammable and explosive environments, but in some specific occasions, the positive pressure explosion-proof mold temperature machine may be more advantageous. For example, in some occasions where constant pressure needs to be maintained, the positive pressure explosion-proof mold temperature machine can be achieved by adjusting the pressure of the positive pressure protection device, while the isolated explosion-proof mold temperature machine cannot meet this need.
Cost: There is little difference between the two in terms of cost, but due to the high technical requirements of the positive pressure explosion-proof mold temperature machine, it may lead to its relatively high level.
Maintenance: There is not much difference between the two in terms of maintenance, and both need to be regularly inspected and maintained. However, due to the high technical requirements of the positive pressure explosion-proof mold temperature machine, more professional maintenance personnel may be required to operate.
