01 Description
Electrofusion coupler is a fitting with an embedded heating coil, the terminals of which are brought to the surface through dedicated electrical connectors.
Pipes are welded using electrofusion couplers through heating the embedded coil when electric current flows through it. This creates a simultaneous melting of the inner surface of the coupler and the outer surface of the pipe, resulting in their fusion into a monolithic joint.

Key advantages
- Speed and accuracy of welding: automatic welding mode available
- Ease of installation: internal stop for centering and fixing pipes inside the coupler
- Tightness: IP68 reliable protection according to GOST 14254-2015
- Open heating coil for direct heat transfer into the pipe
- Electrical contacts with touch protection
- An indicator for visual control of welding
02 Application area
Welding polymer smooth-walled pipes to each other
Intended for welding polymer smooth-walled pipes to each other, watertight connection of smooth-walled pipes with manhole cable sleeves, as well as for attaching expansion funnels and plugs to the ends of smooth-walled pipes under constrained conditions.

Installation specifics
- Permissible installation temperature is between -10 to 45°С
- Can be welded with any type of electrofusion welding device. Welding parameters are automatically read from the coupler’s barcode. Welding requires a device with a constant output voltage of 39,4 V, the welding time is set manually. The welding time is specified on the label with the barcode.
