Where every radiator is born
Our own 6,000 m² facility, robotic welding and multi-stage quality control all under one roof in Svilajnac.

Radiators
Since 1992 we have manufactured NK Lux, NK Standard and NK Term tubular radiators. The radiators are made from welded steel tubes (Č0146) in DC01 material to the EN 10305-3 and EN 10305-5 standards, with output from 300 to 2000 W and 10 bar working pressure.
We offer radiators from 400 to 700 mm wide and 750 to 1860 mm high, tailored to different spaces and requirements.
Certified products
Our radiators carry all relevant European certificates. The quality management system under ISO 9001:2015 guarantees that every piece leaves the facility in full compliance with prescribed standards.
Certified quality
Quality proven by certificates since 1992.
Premium materials
First-grade steel and EU-certified coatings.
Serial tracking
Every radiator receives a unique serial code.
A look inside production
A moment from our facility - from raw material to finished radiator.
From raw material to radiator
Every step under full control - no compromises.
Raw material selection
We source steel tubes and sheets exclusively from reputable European suppliers, each with full quality documentation.
Cutting & bending
Specialised machines precisely cut the tubes to the dimensions of each model, with a tolerance of less than 0.5 mm.
Robotic welding
Tunnel and robotic welders deliver a homogeneous, repeatable weld without human error on every single piece.
Painting & finishing
Electrostatic painting across the full RAL palette. Coating thickness is measured before and after curing.
Pressure testing
Every radiator undergoes a hydro-test at 10 bar before packaging - zero compromise, zero returns.
Packaging & dispatch
Protective packaging and strict logistics ensure the radiator arrives undamaged - on time, to the right address.
