On July 23, the Lemax enterprise celebrated its 30th anniversary. In such a short period, we managed to create a team of 700 employees, organize the production of boilers and steel panel radiators on an area of 33,000 m2, and invest 2.5 billion rubles in the enterprise in 2021. The main success that has been achieved is the recognition of Lemax products by customers. Currently, Lemax is one of the largest manufacturers of domestic gas boilers and steel panel radiators in Russia. According to the Litvinchuk Marketing study (June, 2022), Lemax became the sole leader in the floor-standing boiler market with a more than two-fold lead over its closest competitor with a market share of 22% at the end of 2021.
Every day, the enterprise searches for effective sales points, supplies products through regional representatives and directly through the lemax-kotel.ru website, maintains points of contact with partners and consumers around the clock, takes an active involvement in specialized trade shows and introduces innovative technologies and approaches in heating equipment production, conducts training technical seminars and webinars for partners, provides all the necessary technical documentation and promotional products.
The flagship sales of Lemax heating equipment are non-volatile floor-standing boilers.
In 2022, mass production of a new generation of floor-standing boilers was launched - boilers of the UNO series.
UNO series floor-standing boilers are designed for heating domestic and administrative buildings, private houses, apartments and cottages. This series operates under conditions of natural or forced heat transfer medium circulation.
UNO series floor-standing boilers are steel gas boilers with an improved heat exchanger design, which allows increasing the heat removal area and achieving maximum equipment efficiency. A series of boilers are produced in a power range from 7.5 to 50 kW. The new-generation equipment features an open combustion chamber and a temperature of exhaust gases not exceeding 115°C. The boilers are completely energy-independent, have a reliable 820 NOVA SIT automatic safety device, which allows connecting a Lemax turbo nozzle of the Comfort SE series, room thermostats, as well as a monitoring and control device for IOS and Android via relay type contacts to the equipment. The soft start system of UNO series boilers creates acoustic comfort at the moment of ignition. The engineering center of the Lemax enterprise has further improved the systems of protection against heat exchanger overheating, blowing, and draft interruption. Another advantage of UNO series boilers is the ability to connect the boiler to both vertical and horizontal flues. For ease of boiler maintenance, removable covers of the draft stabilizer and lining are provided.
Access to the main components is provided without disconnecting the boiler from the flue.
The new technological solution of the UNO boiler series provides for:
1. Reducing heating costs by up to 20%. The heat exchange area is increased by 20% compared to models of traditional design, and the number of smoke channels is 2.5 times greater, which provides for achieving maximum efficiency in all operating modes.
2. Reducing gas consumption by up to 10%. Any room thermostat with dry contacts and a remote monitoring and control device can be connected to gas boilers of the UNO series. In this case, the room temperature will be maintained at a given level with high accuracy without clock cycles and in automatic mode.
Boilers can operate on both natural gas and liquefied gas.
In 2022, the company introduced a new series of floor-standing boilers with a cast iron heat exchanger. OMEGA CI boilers are available with power from 16 to 50 kW.
The entire boiler range is equipped with a 820 Nova Sit automatic safety device, that enables connecting a room thermostat to regulate the temperature inside the room with high accuracy, as well as monitoring and control devices for remote monitoring and control of the performance of gas boilers and heating systems via a mobile app.
The two-stage opening of the automatic safety device coil allows for smooth boiler ignition.
OMEGA CI series boilers feature an open combustion chamber and are used in heating systems with forced circulation and operating pressure up to 4 atm. The combustion chamber contains an injection micro-flare burner, operating on the principle of complete pre-mixing of the gas-air mixture. This ensures efficient use of energy resources.
The needle-type heat exchanger is made of cast iron with a minimum wall thickness of 4 mm; stainless steel turbulators are used in the design of the heat exchanger as well. The boilers are fitted with a protection system against draft interruption, soot formation, and blowing out of the boiler, so they can operate stably even with an insufficiently insulated flue.
Other advantages of OMEGA CI series boilers:
Use of original parts.
The boiler requires no mains connection.
For ease of use, the temperature regulator and thermometer are located on the boiler front panel.
Easy boiler maintenance without disconnecting from the flue due to the use of an easily removable lining cover and draft stabilizer.
3-year warranty.
Another new product for 2022 is a series of cast iron boilers - Lider Pro. The boilers are designed to operate in heating systems of private domestics, administrative and industrial premises with both forced and natural heat transfer medium circulation. The series is produced with heating capacity of 16, 25, 35, 40 and 50 kW. The names of the models are marked by the number of heat exchanger sections. For example, the Lider Pro-300 boiler has 3 sections of cast iron heat exchanger and a power of 16 kW.
The new boiler appearance combines the continuity of the well-known Lider series of boilers and the modern direction in the design of boiler linings.
Advantages of Lider Pro series boilers:
Equipped with 820 Nova Sit automatic safety devices.
The boiler requires no mains connection.
Cast iron heat exchanger 4 mm thick, needle type, using turbulators made of stainless steel.
Operating pressure in the heating system is up to 4 atm.
Operation in heating systems with both forced and natural circulation of heat transfer medium in closed and open systems.
Improved system of protection against heat exchanger overheating, draft interruption, boiler blowing out, and soot formation.
For convenience, the temperature regulator and thermomanometer are located on the boiler front panel.
It is possible to connect a room thermostat to regulate the indoor temperature with high precision.
Work in conjunction with a monitoring and control device for remote monitoring and control of gas boiler and heating system performance via a mobile app.
Smooth-start system provides acoustic comfort when the boiler starts.
Easy boiler maintenance without disconnecting from the flue due to the use of removable lining covers and a draft stabilizer.
Warranty – 3 years
All boiler heat exchangers produced at the Lemax enterprise undergo 100% quality control in two stages:
- at the stage of incoming control;
- during acceptance tests.
Hydraulic tests of heat exchangers are performed with an inhibitory composition, which forms a protective film on the walls of the heat exchanger and prevents corrosion
during equipment storage and transportation.
For cast iron heat exchangers, a 50 mm thick heat-insulating material with a foil layer is used, which has the properties of biostability, safety for humans and the environment.
The production also performs an independent audit of ready-made equipment.
Boiler components are manufactured on high-tech automated equipment under the strict supervision of quality department employees at all production stages.
