Device

Lemax boilers are assembled at the company’s own production facilities in Taganrog, but the main elements from other manufacturers, both foreign and domestic, are used. Preference is given to Russian-made housing elements and heat exchangers, and automation, burners and gas, water and temperature control control units from foreign partners, mainly European companies.

Main components and manufacturers:

• Gas burners – POLIDORO. Italian manufacturer specializing in the development and assembly of burners, including for open and closed combustion chambers of gas boilers.
• Gas valve – Sit. Initially, automation for gas equipment with exhaust gas temperature control produced by Italian companies. Now Sit refers more to the design of the gas valve control unit itself; it can be produced anywhere, including in China.

About company

The Lemax company, or rather a group of companies, was founded in 1992. Initially, it was a trading company engaged in the wholesale supply of heating equipment and metal. Later, in the mid-90s, it was decided to create a separate division for the assembly of gas boilers under its own brand. This is also a distinctive feature of Lemax. The main emphasis is on the development and design of gas boilers using imported parts. On the one hand, this eliminates the need to organize your own technological production, but on the other hand, it makes the entire model range quite heterogeneous, without established features and characteristics. Lemax has been the leader in sales on the Russian market many times. The main advantages of the products are attractive prices, an expanded network of stores and service centers, as well as the fundamental use of foreign parts, at least in recent years.
