In 1924, he invented the heating wire for household appliances, and in the same year, he founded the company in Berlin, Germany, and became one of the founders of the global electric heating industry. After more than 90 years of development, Spoaltron is now a professional manufacturer of large-scale electric heating and electric hot water systems in Europe, and its regenerative electric heating equipment has a market share of more than 60% in Germany, France, Belgium, Switzerland and Japan, accounting for 40% of the global market share. Its products have won 36 IF Industrial Design Awards, 9 Red Dot Design Awards, 5 German Good Design Awards, and have been selected as "Super Brands" by The Superbrands Organization, the world's largest authoritative brand review organization, three times.
 
The body of the convection heater CNS-W series uses imported outdoor paint, which is not only beautiful and generous, but also corrosion-resistant and high-temperature resistant, and the heating part adopts a nickel alloy heating core, all-aluminum rib type heat dissipation, high heating efficiency, and the series also has an anti-frost function, in the case of connecting the power supply, the indoor temperature will be automatically turned on when the indoor temperature is lower than 5 °C, so as to avoid indoor electrical equipment being frozen at low temperature, which is very intimate. The IP24 protection protects against the ingress of medium-sized solids and the impact of liquids spilling onto the housing from multiple directions. It is worth noting that this series has CNS150W, 175W, 200W, 250W and 300W models, the biggest difference between these models is the different power ratings, the lowest CNS150W rated power is 1372W, the highest CNS300W is 2800W, the greater the power, the more power consumption, and the heating effect is also better. 250W and 300W both products are rated more than 2200W, must be connected to a 16A socket when in use, users need to confirm whether they have a 16A socket when purchasing, which is best to find an electrician to verify. Although there are also 10A to 16A three-pin adapter plugs on the market, it is not recommended to use them for a long time, and there is a risk that the power cord of the machine may burn out if used for a long time. At present, 150W and 175W are sold less on the market and are more difficult to buy, and 200W, 250W and 300W are priced at 1799, 1999 and 2499 yuan respectively.
