Product Introduction

Piping compressed air heater is a specialized heating device designed for pipeline-installed compressed air systems. It is used to heat compressed air to a specified temperature to meet the process requirements of downstream equipment, prevent condensation water generation in low-temperature environments, and improve the quality of compressed air. It is widely used in industrial manufacturing, food processing, pharmaceutical production, automotive painting, and other industries that require high-quality heated compressed air.

Working principle

Pipeline electric heater is a device that consumes electrical energy to convert it into thermal energy for heating materials that need to be. During operation, the low-temperature fluid medium enters its inlet under pressure, flows through the specific heat exchange channels inside the electric heating vessel, and follows path designed based on fluid thermodynamics principles, carrying away the high-temperature heat energy generated by the electric heating elements, thus increasing the temperature of the heated medium The outlet of the electric heater obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically regulates the output power of the heater according to the temperature sensor signal at the outlet, maintaining a uniform temperature of the medium at the outlet; when the heating element overheats, the independent over protection device of the heating element immediately cuts off the heating power supply, preventing the heating material from overheating, causing coke, deterioration, and carbonization, and severe cases, causing the heating element to burn out, effectively extending the service life of the electric heater.

Installation Instructions

Step 1: Confirm that the pipeline pressure, air flow, power supply voltage and other parameters match the product nameplate parameters before installation.

Step 2: Cut off the air supply and power supply of the pipeline system, and empty the residual compressed air in the pipeline.

Step 3: Install the heater in the correct direction (the inlet and outlet are marked on the shell, and the flow direction of compressed air shall be consistent with the mark).

Step 4: Connect the inlet and outlet pipes tightly, conduct a pressure test to confirm no leakage, and then connect the power supply and temperature control system according to the wiring diagram.

Step 5: After the installation is completed, conduct a trial run, check whether the temperature rise is normal, and put it into formal use after confirming that there is no abnormality.
