This winter has been one of the coldest in a century. It is said that the extreme cold weather of Mohe in Heilongjiang province has been -50 degrees Celsius, and some parts of Jilin Province have been close to -40 degrees Celsius, and the ski resort city of Jilin has also seen extreme cold weather of -35 degrees this year. The appearance of extremely cold weather is a test for air source heat pumps, and some brands with insufficient configuration and poor performance are facing huge challenges in the Northeast this year. However, there are also some brands that win by quality, and their products have excellent performance in the Northeast, such as Clariant.

Colant heat pump began to enter the Northeast market in 2017, is one of the first brands in the domestic heat pump industry to enter the Northeast market, and has been running stably for more than 6 years. There are many cases in extreme cold areas such as Jilin, Heilongjiang and Liaoning. The main products of Corant in Northeast China include household split ultra-low temperature variable frequency air source heat pump (internal unit integrated with water pump, expansion tank, etc.), commercial fixed frequency split heat pump unit (compressor, heat exchanger and other waterways are integrated), ultra-low temperature fixed frequency integrated machine. It is worth praising that this year, the Colant ultra-low temperature fixed frequency heat pump unit can also have excellent performance in the environment of -35 degrees. We came to Jilin City Wujiashan ski resort, this ski resort is a more famous ski resort in the urban area of Jilin City, installed two Colant ultra-low temperature fixed frequency heat pump units. Because the ski resort is a mountain area with low temperature and high humidity after snow, it is a very big challenge for the crew. The lowest temperature this year has been -35 degrees, but the Clariant heat pump can guarantee indoor temperatures of more than 22 degrees throughout the winter.

The reason why Colant's ultra-low temperature heat pump unit can be applied so well in extremely cold weather is mainly in three aspects: the first is the increase in product configuration. According to the actual situation of the extremely cold environment, Colant products in the evaporator and heat exchanger are selected to match. For example, 30P units often need to increase the heat exchanger by 10%, so as to ensure that enough heat can be absorbed in winter. In the case of such fierce competition in the market, many brands are reduced, and Colant also added, which is very rare. The second is the control system, the control system of ultra-low temperature products is very critical, the operation logic of the system, the defrosting logic is very important, in the extremely cold area, especially the defrosting is not solved well, the unit once defrosting is not clean, repeated defrosting will affect the heating time of the unit, so that the indoor temperature is not reached, the unit will run for a long time. Running costs will also increase significantly. In the defrosting, Clant has its own patented technology, which can achieve precise frost. The third is the Internet of Things control system. In 2017, Corant standardized the Internet of Things module on the product to achieve remote control, remote debugging, and remote operation and maintenance, saving customers a lot of energy. When it comes to Colant's heat pump, the owner of the ski resort is not stingy with the thumbs up, especially this year, there are a lot of tourist skiing people, and if the indoor temperature is not up to standard, the business will be affected. In addition to the five mountain ski resorts, the case of the installation of Corant in Jilin City is also very many, such as the love Lvliang Villa, Qingshan box resident hotel, Taiyuan Resort Hotel, Jinqiu leisure Hotel, etc., these business places often pay great attention to the stability of the product when choosing the product, and often need to do a multi-party comparison when choosing the heat pump, and even go to the case site investigation. The final choice of Colant is also because of the excellent products, good reputation in the local.

Colant was founded in 2006, the current product line is divided into four categories (cold and warm, cold chain, drying, hot water), is currently the domestic heat pump industry product line is one of the most abundant enterprises. It has been exporting for 17 years since its establishment, covering 45 countries and regions. In 2022, Colant began to vigorously expand the domestic market, establish a production base in Liaocheng, Shandong, and eventually form two major production bases in the north and south, of which the Guangdong production base reached 20,000 square meters, and the Shandong base reached 30,000 square meters, which well met the domestic market demand. In 2023, Corant will continue to uphold the principle of quality first, force the domestic market, and become a heat pump enterprise with leading technology, excellent quality and comprehensive strength.
