Exhaust ducts belong to a circulatory system and are generally used for indoor or industrial ventilation, such as kitchens, bathrooms, gas, garages, mechanical ventilation, exhaust gas emissions, and ventilation rooms, etc. All these equipment need to use exhaust ducts for circulating discharge. Since the exhaust pipe has liquid in some equipment during operation, it is easy to condense when encountering cold air during the exhaust process. After condensation, the exhaust effect will be affected. Therefore, the exhaust pipe needs to be heated and insulated.
Depending on the temperature to be maintained in the exhaust duct, the model of the electric heating cable used is different. If the temperature requirement is not high, you can choose the self-limiting temperature electric heating cable. The self-limiting temperature electric heating cable can be divided into basic type and explosion-proof. Type, reinforced, anti-corrosion type, can maintain up to 105℃, temperature is automatically controlled, can be cut at will, installation is very convenient.
If the self-limiting temperature electric heating cable cannot reach the required temperature, you can use the constant power electric heating cable. The constant power electric heating cable has a constant power and will not change with changes in the environment or the temperature of the medium. It needs to be used with temperature control. Constant power electric heating cable can be divided into parallel and series. Parallel constant power electric heating cable is generally used for large pipelines and tanks. The serial constant power electric heating cable is used for heating long-distance pipelines. It needs to be selected according to the actual situation.
For the different environmental temperature requirements of different equipment, the electric heating cable has the corresponding model selection. If you don’t know how to choose the type, you only need to tell the relevant parameters of the equipment to the electric heating manufacturer. The manufacturer or a professional technician will do it for you. Recommend suitable electric heating model.
