Except standard Hailin thermostats,we also offer ODM service for customers.

Our advantage of ODM:

R&D capacity:

1) R&D personnel account for 15% of the total number of employees; this proportion ranks first in China's thermostat industry.

2) After the confirmation of the technical requirements of the new product project, the first version of the functional prototype will be released within an average of 12 weeks.

3) There are functional tests and reliability tests before mass production of new products.  If the customer has no special requirements for the two tests, we will be tested according to Hailin Enterprise Standard (Hailin Enterprise Standard is established based on CE standards, and the four standards of static electricity, lightning surge, pulse group, and withstand voltage insulation are higher than CE). And Hailin Laboratory is a TUV witness certification laboratory, which is the only one in China's thermostat industry.

4) The drafting and compiling unit of the Chinese national standard "General Technical Conditions for Indoor Temperature Controllers".

5) Annual R&D investment accounts for more than 6% of the total cost.

Production capacity: The first manufacturer in China's thermostat industry to establish an automated assembly and packaging line. The annual output of thermostats and controllers is 5 million. 

Quality: ODM cooperation has been carried out with more than 20 HVAC equipment manufacturers at home and abroad, and the PPM value of some customer products can reach 100PPM or 20PPM. (Numbers are the most convincing)

Beijing Hailin Control Technology Inc. is a kind of R&D manufacture of thermostat, DDC, sensor, automatic control valve and building automation system, energy management system and smart home system etc hvac control product.

Hailin uses automatic control technology to monitor, control, analyze and manage the air conditioning, heating, fresh air, hot water, lighting, curtains and temperature, humidity, air quality and energy consumption in the building to achieve a comfortable and healthy indoor environment in the building and energy saving.
