When purchasing 135 flange heating elements, parameters such as design power, operating voltage, and protection rating need to be compared one by one with the on-site working conditions. The following key parameters are summarized from the perspective of selection confirmation for purchasers' reference.
I. Confirmation of Power and Voltage Matching
The design power range of 135 flange heating elements is 1KW to 2000KW, and the operating voltage can be 220V or 380V. During selection, the required power should be calculated based on the heating medium, heating time, and heat dissipation conditions, and it should be confirmed that the power supply voltage is consistent with the on-site power grid. The allowable deviation of the operating voltage shall not exceed 1.1 times its rated value; exceeding this range may affect the service life of the heating element. Purchasers need to obtain the heat load calculation results from technical personnel to avoid selecting power that is too large or too small.
II. Correspondence Between Protection Rating and Installation Environment
The protection rating can be determined between IP45 and IP68 according to actual needs. For occasions such as oil tanks and water tanks where splashing or moisture may exist, a higher protection rating is recommended; for dry indoor environments, IP45 can meet basic protection requirements. When purchasing, the environmental conditions of the installation location need to be clarified, and installation dimensions such as flange specifications and immersion length should be confirmed with the supplier.
The operating temperature range of 135 flange heating elements is 20 to 1050°C, the operating pressure is 0.6 to 20Mpa, and the temperature control accuracy can reach ±1°C. Different media and processes have greatly differing requirements for temperature and pressure. Purchasers should specify the actual working condition parameters in the order so that the supplier can configure according to needs.
