What FRIZLEN GmbH u. Co KG. does

FRIZLEN GmbH u. Co KG. is a German manufacturer of industrial power resistors (Leistungswiderstände), founded in 1914 and headquartered in Murr, Baden-Württemberg. The company designs and produces custom power resistors ranging from 10W to several hundred kW, organized across six product families: T100 tubular fixed resistors, T300 flat resistors, T400 load/test resistors, T600 steel-grid resistors, plus lamina and wirewound rotary types. These components serve controlled energy dissipation in braking, load testing, filtering, damping, and crowbar/FRT applications within drive technology, cranes and logistics, mobile machinery, energy technology (wind, PV, grid), power electronics, marine, and testing/laboratory sectors. End customers include OEMs and system integrators across these segments, with publicly referenced wins including a 39-resistor order from a German state civil protection authority and a 156-resistor, 1.05 MW data center deployment for SPIE Lück GmbH.

The company operates from a single 2,700+ m² manufacturing facility with in-house sheet metal processing supported by Trumpf punching lasers (including a Trumatic 1000) and TruBend bending machines. Manufacturing is vertically integrated in-house, enabling custom-engineered configurations rather than catalog distribution. The business is family-owned, now in its third and fourth generation of leadership (Ernst Gehrung, Julia Horn, Alexander Horn), employing more than 150 people.

FRIZLEN sells direct to industrial customers and through exclusive distributors in Finland/Baltic states and Italy, complemented by preferred trading partners across Europe, Israel, Turkey, China, Korea, and North America, with active presence in over 60 countries. Pricing is project-based and inquiry-driven, reflecting the custom-engineered nature of the offering rather than standardized catalog sales.

Core offering

FRIZLEN designs, manufactures, and sells power resistors for electrical energy dissipation from 10 W to several hundred kW, covering tubular (T100), flat (T300), load and test (T400), and steel-grid (T600) resistor families, as well as lamina-type resistors. Products serve as braking, load, starting, discharge, filter, and testing resistors for industrial applications including drive technology, renewable energy, cranes, mobile machinery, power electronics, marine, and laboratory/testing environments. The entire range is manufactured in-house at the Murr facility and sold directly to industrial customers worldwide, complemented by a network of regional channel partners.

Product overview

FRIZLEN is a leading manufacturer of power resistors with a comprehensive product portfolio spanning six main product groups: T100 tubular resistors (12W-1kW), T300 flat resistors (compact designs with IP54/IP67 protection), T400 load and test resistors (up to 500kW), and T600 steel-grid resistors (up to 500kW). The company offers resistors for power dissipation from 10W to several hundred kW, with resistance values from 1mΩ to 200kΩ. Product applications include braking resistors, load resistors, starting resistors, discharge resistors, filter resistors, and testing resistors. FRIZLEN's unique selling point is integrated project handling from technical consulting through customer-specific design to order-related manufacturing.
