Sino-foreign joint venture - Ningbo Hongzhan Air Conditioner Equipment Co., Ltd. is a member of China Refrigeration and Air-Conditioning Industry Association, and has got ISO9001:2000 International Quality System Certification and has been assessed a UNIT of "Honoring Contract and Keeping Credit" of Zhejiang Province for consecutive years among industrial and commercial enterprises. We are one of the "Top ten integrity Enterprises of Assured Product Quality and Customer-satisfaction Industry of China". Our firm also drafted the Nation GB/T Standard of the People's Republic of China and Design and Installation requirements on refrigeration systems and heat pumps-hose parts and expansion joints for the vibration isolators. "Hongzhan" has a history of sixteen years of business, and has always been committed to producing decontaminating tank equipment of central air-conditioning, gaining the favor of a large number of domestic and foreign clients for inherent reliable quality and unique innovation. Our export business is expanding unceasingly. "Hongzhan" has applied for a utility model patent of non cool-bridge frameworks of air-conditioning units with patent Number of [ZL520102817.6].
For both Inside and outside surface layers, our firm uses aluminum alloy material with characteristics of non-condensate fog, no leakage, no smell, and distortion temperature of heat insulating strip >250.5 conforming to national standard of GB/1633-79; elongation at break of 3%, conforming to national standards of GB/T1040-92, which has completely solved the serious quality problem of aluminum-plastic frameworks of cold-proof bridges. Because inner layers of aluminum-plastic frameworks are combined with PVCs, the heat distortion temperature is only <60, when the surface air coolers of air conditioning heats and air outlet systems often produce smell, and the PVC of surface air coolers is easy to crack and deform to produce leakage when refrigeration. "Hongzhan" has been rewarded the title of "Patent Model enterprise" and we are the member of Ningbo Association for The Protection of Intellectual Property. The MGO non cool-bridge closed observation windows have transparent cavity. The cold-bridge-free access doors have sealed, pressure bearing, oil proof, and condensate-fog-free structures. KQ series door locks have key series and opening inward-outward series, with characteristics of large handle shape, flexible rotating, large compression force and good sealing performance, which have been awarded three patents and gained trust and praises from domestic and foreign clients.
"Seek development depending on new products" and "survive depending on quality" are our consistent tenets. With unceasing efforts of Hongzhan employees, the scale of production is expanding continuously. The new mold machining center and standard assembly plant have been built and air conditioning and purifying equipment assembly lines have been put into use.
Adhering to the business philosophy of "integrity, Innovation, specialty and excellent", all people of Hongzhan will continue to launch new products, and research and develop further non cool-bridge air-conditioning and purifying equipment, to realize our commitment of "exceeding customers' expectations" with "excellent quality and sincere service", gaining markets, development and performance in the future. Hongzhan people are further willing to work together to develop, seek common development and create brilliance with foreign and domestic clients!
