SOLO Swiss manufactures advanced industrial furnaces for the heat treatment of metals since 1924. SOLO Swiss offers atmosphere furnaces, batch furnaces, bell-type furnaces, continuous furnaces, mesh belt furnaces used in variety of heat treatment processes: carburizing, hardening, tempering, annealing, austempering, nitriding, brazing, carbonitriding, sintering, nitrocarburizing, oxinitriding, quenching.

All SOLO furnaces are equipped with alloy muffles to provide precision heat treatment and feature quick quenching. SOLO furnaces are well suited for the treatment of the small complex metallic parts requiring an enhanced heat treatment and reduced distortion. Parts include: springs, clips, fasteners, coins, needles, hooks, ball bearings, parts for the aeronautics, cutlery, watch-making industry, micromechanic, as well as, long parts for which the bell furnace is most suitable. In all these fields, SOLO Swiss Group’s customers have been amongst the most famous names in these industries for more than 40 years.


Profitherm type batch furnaces

This unique, multifunctional arrangement of bell-type furnace and multiple quench tanks, allows a direct & rapid transfer of the load from the furnace(s) to the quench tank(s). The modular design enables easy expansions and allows all types of atmospheres and quench media.


SOLO Swiss Continuous Furnace

SOLO Continuous furnaces line which combines process quality and easy maintenance. A muffle in refractory steel permit rapid conditioning of the atmospheres for various heat treatments.


SOLO continuous furnaces with online quenching

Mesh Belt Furnaces. Highly-focused heat treatment for guaranteed quality thanks to processes performed under confined atmospheres within a metal gas-tight channel and an efficient convection of the gas.
Numerous combinations of elements upstream and downstream of the furnace allow continuous or discontinuous flow depending on your work pieces. A refractory steel channel allows rapid changeover and conditioning of atmospheres for the following treatments: Austenitisation – Carburising – Carbonitriding
