Compressed air heater is an industrial equipment designed specifically for heating compressed air. It uses electricity or other energy sources to raise the initial temperature of compressed air to the required temperature for the process, preventing condensation caused by air expansion. It is widely used in industries such as painting, food processing, and pharmaceuticals.
Core functions and values：
Prevent condensation caused by expansion and cooling of compressed air during use, and protect equipment and product quality
Provide stable and controllable hot air to meet special process temperature requirements
Improve the efficiency of pneumatic equipment and reduce energy consumption
working principleConvert electrical energy into thermal energy through electric heating elements (such as stainless steel electric heating tubes), and transfer it to compressed air through a heat exchanger
core parameters：
Power range: 3kW~300kW, single flow rate can reach 2000Nm ³/h
Temperature control accuracy: ± 1~± 2 ℃, fast response time (≤ 10 seconds)
Temperature: Standard type 120 ℃, high temperature type up to 800 ℃
Applicable pressure: 1.6MPa, protection level IP54/IP65
Clean and emission free, especially suitable for the food and pharmaceutical industries
Accurate control, simple operation, and can achieve automation
Compact structure, small footprint, easy installation
Core workflow：
Compressed air enters the heater through the inlet
Contact with heating element through built-in heat exchanger
Heat energy is evenly transferred to the air, causing an increase in temperature
The temperature control system monitors and adjusts the output temperature to ensure stability
The heated air is sent from the outlet to the process equipment
key component：
heating elementThe electric heating type uses stainless steel electric heating tubes; Steam type finned heat exchanger
Temperature Control SystemHigh precision sensor+PID controller, control accuracy ± 1~± 2 ℃
safety protectionMultiple protections including over temperature cut-off, dry burning protection, pressure monitoring, grounding protection, etc
insulation layerEfficient insulation materials such as aluminum silicate fibers reduce heat loss and have a surface temperature of<50 ℃
