Electrofusion welding is the name given to resistive implant welding of thermoplastic pipes. It is one of two main techniques used for the joining of polyethylene gas and water pipes. Electrofusion welding employs fittings that are placed around the joint to be welded. Metal coils are implanted into the fittings, and electric current is run through the coils to generate heat and melt part of the pipes, forming a joint upon solidification. There are two possible fittings used in electro fusion welding: couplers and tapping tees (electrofusion saddles). Electrofusion Machines/Electrofusion Welders are used for electrofusion fittings welding. Electrofusion Fittings are a heat treatment method compared to butt fusion methods and are used to generate heat. Electrofusion welding is a type of pipe welding and polyethylene fittings, in which there are special connections that have electrical resistance wire to create welding melting temperatures. The electric current is transmitted through the electrofusion welding eequipment and through the control box to the two ends of the connection.

EFC-1.0HE EFC-2.0HE
Dual filter (Pre filter + HEPA filter), Pre filter that effectively prevent large amounts of dust, hair and other
large pollutants, while protecting the HEPA filters are from being clogged by bigger pollutants. The
efficiency of the HEPA filter is up to 99%, and the outdoor air is cleaned and continuously distributed
into the room.
The design of EFC 1.0/2.0 ensures adequate oxygen content in the room. Backward inclined impeller fan
and maximum external static pressure can reach 300Pa to meet high air volume and low noise.
