Every day, the Lemax 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.
Lemax currently ranks 1st in the production of floor-standing gas boilers and 2nd among heating equipment manufacturers in Russia (based on a study by Litvinchuk Marketing, June 2022).
Lemax offers its customers and partners a wide selection of high-quality heating devices. Every year, energy-efficient individual heating is becoming increasingly popular, displacing centralized heating, and domestic gas heating boilers and water heaters are increasingly being installed in cottages, private houses, country buildings, and city apartments.
The model matrix of Lemax heating equipment is constantly expanding and improving. Our in-house engineering center is constantly dedicated to developing new models of heating and water heating gas equipment, enhancing the technical and operational products characteristics every year. A wide range of products covers the entire variety of modern heating devices. Lemax produces heat-only and combi floor-standing gas boilers, wall-hung boilers, electric boilers, instantaneous gas water heaters, and steel panel radiators.
The flagship sales of Lemax heating equipment are floor-standing boilers. The Prestige, Uno, and Omega series boilers have a new-generation heat exchanger design.
The Prestige, Uno, and Omega series gas boilers are floor-standing, non-volatile boilers with a steel heat exchanger, operating in open and closed heating systems with both natural and forced circulation. The Prestige and Uno boilers are available in a power range from 7.5 to 50 kW, and Omega – from 12.5 to 50 kW. The entire model range comes fitted with a reliable 820 NOVA automatic safety device. This automatic safety device provides a number of additional advantages:
- the availability of a temperature controller with temperature gradation on the boiler front panel, enabling the user to select the optimal thermal mode;
- room thermostat connectivity to regulate the indoor temperature with high accuracy;
- work with the LEMAX ZONT monitoring and control device for remote monitoring and control of the performance of a gas boiler and heating system when connected via a potential-free (relay) contact type;
- boiler operation with an indirect heating tank using the Lemax indirect heating tank control device;
- working with the Lemax turbo nozzle for combustion product forced removal in the absence of a built-in flue or in case of its malfunctions;
- soft start system providing acoustic comfort at the moment of ignition.
The Prestige, Uno, and Omega series boilers pack an improved heat exchanger design, allowing for a large heat removal area, which results in maximum energy efficiency of the equipment.
The new technological solution for Prestige, Uno, and Omega series boilers enables:
- 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.
- reducing gas consumption by up to 10%. Any room thermostat with dry contacts and a LEMAX ZONT remote monitoring and control device can be connected to the boilers. In this case, the room temperature will be maintained at a predetermined level with high accuracy, excluding clocking cycles.
The new generation equipment features an open combustion chamber, meaning the temperature of the flue gases does not exceed 115 °C. The boilers can operate on both natural and liquefied gas. All equipment is protected against heat exchanger overheating, blowing out, and draft interruption. Another advantage of boilers is the option to connect the boiler to both vertical and horizontal sections of the flue. For ease of boiler maintenance, removable covers of the draft stabilizer and lining are provided, providing access to the main components without disconnecting the boilers from the smoke removal system.
In 2023, the Lemax company introduced a new product - a gas boiler of the Omega E series. The new boiler series is the first model among energy-dependent floor-standing boilers packing an innovative heat exchanger design. The Omega E series is available with power from 12.5 to 50 kW. The boilers feature an open combustion chamber, a steel heat exchanger with an operating pressure of up to 3 atm. The entire Omega E series of boilers is equipped with a Russian control board and an original 845 SIGMA safety automatic device. The boilers are protected against heat exchanger overheating, draft interruption, soot formation, and boiler freezing. Omega E boilers can operate in heating systems with forced and natural heat transfer medium circulation.
Thanks to the new technological solution being employed in OMEGA E boilers, we managed to reduce heating costs by up to 20% due to an increased heat exchange area by 20% compared to common-design models and a 2.5-fold increase in the number of flue exhaust channels. Additional gas consumption savings of up to 10% can be obtained by connecting a room thermostat with dry contacts or a LEMAX ZONT remote monitoring and control device. Optimization of the main burner operating modes, implemented by the flame modulation function in combination with the innovative design of the heat exchanger, ensures efficient combustion of the gas-air mixture in full volume supplied to the burner, eliminating excess gas consumption typical of boilers in clocking modes. Efficient boiler operation is further achieved due to the minimum ratio of the volume of water in the boiler to the weight and area of the heat exchanger.
Mega E series boilers can also be connected with an indirect heating tank, an outdoor temperature sensor, a Lemax turbo nozzle of the Comfort series for forced removal of exhaust gases, pumps of heating and hot water supply systems. The boilers are resistant to changes of voltage (180 - 245 V) and gas pressure (6 - 25 mbar). The new ignition system installed on the boilers ensures stable ignition of the gas-air mixture. An informative color display with a text parameter description in Russian reflects the user and service settings of the boiler. In Omega E series boilers, the amount of thermal insulation material used has been increased. The unified dimensions and location of the connecting pipes provide for installing new boilers to replace the popular series of boilers: energy-dependent CLEVER and energy-independent "Premium".
In October 2023, Lemax will launch production of a new series of energy-dependent boilers with a cast iron heat exchanger – OMEGA CI E.
Boilers are produced with power from 16 to 50 kW. The entire range of boilers is equipped with a 820 Nova automatic safety device, that enables connecting a room thermostat to regulate the temperature inside the room with high accuracy, as well as control and manage LEMAX ZONT for remote monitoring and management of heating system performance via a mobile app.
The boilers feature an open combustion chamber and can be 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 boilers have a needle-type heat exchanger made up of cast iron with a minimum wall thickness of 4 mm. 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.
OMEGA CI E series boilers can be connected with an indirect heating tank, an outdoor temperature sensor, heating and hot water pumps. The new series of equipment is fitted with a Russian control board and an informative color display with a text description of the parameters in Russian, reflecting the user and service settings of the boiler.
Other advantages of OMEGA CI E series boilers include:
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.
All components of Lemax boilers are manufactured on high-tech automated equipment under the strict control of quality department employees at all stages of production.
All boiler heat exchangers produced at Lemax undergo 100% quality control in two stages:
- following welding work completion;
- 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. The production also performs an independent audit of ready-made equipment.
