The company has been actively developing since 1992 and now hosts two powerful production centers: a plant for household gas equipment production and a plant for steel panel radiator production.
All the company's products are manufactured in line with international quality standards. The plants employ the top-end technological solutions that make the products convenient and safe to use, easy to maintain, and effective in application.
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).
The flagship sales of Lemax heating equipment are floor-standing boilers.
Following the model range of boilers with microprocessor control of the CLEVER series, Lemax arranged the production of hot water boilers of the CLEVER L series with a power from 100 kW to 200 kW. Currently, boilers with a nominal heating output of 40, 50, 80 and 90 kW are also produced. CLEVER L boilers are designed for use in heating systems operating with forced heat transfer medium circulation, demonstrating high efficiency with a minimum ratio of heat transfer medium volume to heat exchanger area and weight.
Design features
The heat exchanger is of the high-speed water-tube type (meaning water circulates inside the pipe). The wall thickness is 3.2 mm, and the maximum operating pressure of the heat transfer medium in the heating system is 6 atmospheres.
This design provides strength margin, ease of maintenance, and the ability to be used at sites with a maximum equipment weight limit. The boiler dimensions allow moving it into the room through a standard 900 mm opening, and, if necessary, dismantling the heat exchanger without violating its tightness.
Connection to the heating system is performed via a flange connection with overhead outlets (the boiler is equipped with gaskets and mating flanges as standard). This solution greatly simplifies the installation and maintenance of the system and allows for more efficient use of the boiler room space.
The heat exchanger is coated with anti-corrosion Certa enamel, which can withstand temperatures up to +950 °C, and is also treated from the inside with a specialized inhibitory compound that provides protection against corrosive effects (oils, salt solutions, etc.). In aggregate, this helps increase the durability and reliability of Lemax equipment.
Main advantages of CLEVER L boilers
- The use of an operating algorithm that provides smooth power modulation in a ratio of 1:3, which significantly expands the scope of device application and ensures minimal load on the heating system components.
- High automation of the boiler operation, including ignition, maintaining a temperature specified by the user or calculated by a microprocessor, based on data received from sensors, telemetry, and remote control using the industrial ModBUS protocol.
- High reliability. The boilers have built-in modern protection against freezing, overheating, interruption of air flow, and demonstrate resistance to gas pressure surges in the range from 6 to 25 Mbar and network voltage in the range of 180–245 V.
- Advanced connectivity options. CLEVER L boilers can be connected to an indirect heating tank, an outdoor temperature sensor, circulation pumps, thermostats to regulate the temperature of the heat transfer medium depending on room conditions, remote monitoring and control systems.
- Implemented thyristor control of the boiler with increased resource potential.
- The equipment warranty period is 24 months.
- Option to install boilers in a cascade.
- Use in outdoor and rooftop boiler rooms.
In 2024, mass production of a new boiler model with an OMEGA CI E cast iron heat exchanger will be launched.
OMEGA CI E boilers will be available in 16, 25, 35, 40, and 50 kW models.
The boilers feature an open combustion chamber, a 4 mm thick cast iron heat exchanger, and a working pressure of up to 4 atm.
The entire OMEGA CI E series boilers is equipped with a Russian control board and the original 845 SIGMA safety automatic system.
The boilers are protected against heat exchanger overheating, draft interruption, soot formation, and boiler freezing.
OMEGA CI E boilers can operate in heating systems with forced heat transfer medium circulation.
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.
The OMEGA CI E series boilers can be connected to any room thermostat with relay type contacts, a LEMAX ZONT remote monitoring and control device, an indirect heating tank, an outdoor temperature sensor, heating and HWS pumps.
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.
The amount of thermal insulation material used on OMEGA CI E series boilers has been increased.
Low noise level.
Easy boiler maintenance due to the quick-detachable top panel.
