Otlan Lee Weser: Healthy Development
[Li Weize]: This year we launched five new water heater products DSF588, DSF526, DSF522, DSF423, ZDSF860. The characteristics of these new products are that they are all intelligent variable frequency thermoelectric water heaters, of which DSF588 is a higher-end intelligent frequency conversion full-temperature electric water heater. Since September 2011, Autelang has abandoned the production and research and development of instant-type electric water heaters with gear adjustment.

Kids & Youths Helmets
Kids and youths Cycle Helmets are designed
to be light, comfortable and allow for growth, they are specifically designed
with this in mind to ensure your child is comfortable whilst wearing it and
enjoys the ride. When measuring your child's head you need to measure around
the circumference, in-line with the temples and above the ears, head shapes
will vary so most will come with foam padding which can often be moved around
to ensure a good fit.
In order to cycle on the road or compete in
a race it may be a legal requirement in your country to wear a helmet certified
to a specific standard or an international equivalent. All helmets sold are
certified and labelled with a European CE EN1078 standard. Please check your country`s
requirements to see if this is sufficient and if necessary contact the
manufacturer to see if this helmet has been additionally certified for your
country.

The development of instant electric water heaters has gone through four stages:
The first generation is the gear adjustment control technology. The power is adjusted by the gear position to adjust the temperature. The simple product has only three adjustments, and the slightly better one is set to seven to nine adjustments. The temperature control is not accurate. When the voltage, water pressure, and inlet water temperature fluctuate, it will be hot and cold, and the comfort will be poor. 
The second generation is the stepless temperature control technology. The microcomputer is used to subdivide the output power of the water heater into countless tiny gears through the thyristor inverter controller. It is generally divided into 20~30 gears, and each gear is adjusted by about one degree, which can accurately control the water temperature. However, when the voltage, water pressure, and inlet water temperature fluctuate, it will still be hot and cold, and the comfort is limited.
The third generation is intelligent frequency conversion thermostat technology. According to the temperature sensor and the flow sensor, the microcomputer sets the dynamic data of the temperature, and adjusts the power at any time through the thyristor to achieve a constant water temperature when the voltage, water pressure and inlet water temperature fluctuate. More precise temperature adjustment and good bathing comfort.
The fourth generation is intelligent frequency conversion full temperature technology. According to the temperature sensor and flow sensor, the microcomputer sets the dynamic data of the temperature, adjusts the power at any time through the thyristor, and the variable frequency motor adjusts the water volume to achieve the constant temperature of the water at any time. The temperature adjustment is more precise, and the water temperature is constant at any time, and the bathing comfort is better.
The constant temperature technology completely solves the problem of water temperature, water pressure, voltage change and water temperature change in the installation of the compartment, and improves the quality of bathing life. It is the instant electric water heater with the highest bathing comfort. Aotelang intelligent frequency conversion full temperature technology also won the "Innovation Technology Award" at the exhibition.
In order to allow customers to enjoy the better bathing enjoyment brought by scientific and technological progress and promote the industry's normative and healthy development, Otlan launched the "constant temperature storm" in September 2011, which opened the prelude to the industry reshuffle. Specific measures include the complete elimination of gear adjustment models, the addition of a number of thermostat models, and the significant reduction in the price of thermostats and stepless adjustment models.
In addition, Autelang showcased a full range of dual-mode electric water heaters. After more than 20 years of development, the storage type electric water heater has experienced single-biliary single-core heat storage, single-biliary dual-core fast heat, single-biliary dual-core fast heat (layer heating or energy heating), and double-biliary quad-core dual-mode four. Stages. The dual-mode electric water heater adopts the instant mode in spring, summer and autumn, that is, it is hot immediately; in winter, it adopts the pre-heating relay mode, only need to preheat for about ten minutes. The Otlan dual-mode electric water heater is small in size, fast in heating, large in hot water, can achieve six times capacity increase, beautiful appearance, energy saving and low installation conditions. It is an electric water heater that is more suitable for the Chinese market.
