30 years of expertise

During the past decades we have gained all the knowledge and dexterity we can proudly offer to our clients around the globe. Cutting edge pre-production technologies as well as 3 types of foundries and variety of advanced finishing works are the reasons we will very likely meet your demanding requirements.

Future belongs to aluminium

We believe that aluminum is a metal that now has, and in the future will have, an even greater share of components without which industrial production and technology can not sustain.

That is why we use the latest production technologies that are environmentally friendly and we invest in the development of the company so that we can provide our customers with all the services (from the design of the shapes to any surface treatment or inspection) that are necessary for the proper functionality of the product.

History we are proud of




Company UNITHERM, s.r.o. is registered in the Commercial Registry of the Regional Court in Ústí nad Labem, Section C, Insert No. 245.


Award of Prince Henrik of Denmark

Commercial, designing and implementation works for the heating plant industry including heat production operations by means of co-ownership of a heating plant company. UNITHERM becomes an exclusive sales representative of the Kamstrup company and launches their metering devices onto the Czech and Slovak market. Award of the Association of Danish Enterprises in form of a diploma and a medal of His Majesty Prince Henrik of Denmark for strengthening of business activities between both countries.


Aluminium age

The company expanded its business activities by starting a foundry specialised in sand casting of aluminium products.


ISO certification

The foundry expanded its activities by casting aluminium products into metal moulds and also by providing other technologies, such as impregnation, heat processing of castings and sub-assemblies. Certification for ISO 9001 and 14001. The Energo Division continues building boiler rooms and other units in the area of heating plant industry.


Foundry expansion

Construction of new sand casting foundry for production of heavy and large castings. The Energo division concentrates on the sales of Nivolair heating units, Oilon burners and Kamstrup energy meters. As far as the construction business is concerned, the company specialises in the designing and construction of power centres.


SVTI Certification

Reliability and consistent manufacturing process make us an authorized holder of this certification. This one is mostly searched for by customers in the energy industry.
