Instructions for using duct heaters:

In terms of control, it is necessary to add a linkage device between the fan and the heater to ensure that the heater starts. It needs to be started after the fan starts working

Okay. After the heater stops working, the air

The machine must be delayed for more than 3 minutes to prevent damage to the heater due to overheating. In terms of single circuit wiring, it must comply with NEC standards, with each

The circuit current should not exceed 48A. passageway

The gas pressure heated by the heater generally does not exceed 0.3kg/cm2. If you want to exceed the above pressure specifications, please choose a circulating heater. low temperature

The highest temperature for gas heating with a type of heater

Degree not exceeding 160 ℃; Medium temperature type shall not exceed 260 ℃, and high temperature type shall not exceed 500 ℃.

1、 The main uses of ultrasonic cast aluminum heating plates are:

Widely used in plastic machinery, molds, cable machinery, alloy die-casting machines, pipelines, chemicals, rubber, petroleum and other equipment.

2、 Technical characteristics of ultrasonic cast aluminum heating plate:

Using tubular electric heating elements as the heating element and bent into shape, the mold is made of high-quality metal alloy material as the outer shell and centrifugally cast into various shapes, including circular, flat, right angle, air-cooled, water-cooled, and other special shapes. After precise processing, it can tightly fit the heated body

The surface load of cast aluminum can reach 2.5-4.5w/cm2, and the maximum working temperature is between 300-450 ℃;

The surface load of cast copper can reach 3.5-5.0w/cm2, and the maximum working temperature is between 500-600 ℃;

The surface load of cast iron can reach 4.5-6.0w/cm2, and the maximum working temperature is between 550-700 ℃.

Metal casting heater is an efficient and uniform heat distribution heater made of metal alloy with excellent thermal conductivity, ensuring uniform hot surface temperature and eliminating hot and cold spots in the equipment. It has advantages such as long service life, good insulation performance, strong mechanical performance, corrosion resistance, and magnetic field resistance. Increase the external heat dissipation surface
