In 2006 Start production of refrigeration and heating system equipments.

In 2007 Developed the first generation of refrigeration and heating thermostat and establish the LNEYA CO., LTD.

In 2008 Developed the first generation of refrigeration and dynamic temperature control system.

In 2009 Developed the second generation of refrigeration and heating thermostat.

In 2010 Established WUXI GUANYA REFRIGERATION TECHNOLOGY CO., LTD.

Developed the second generation of refrigeration and heating dynamic temperature control system.

Developed the refrigeration and heating dynamic temperature control system & low temperature freezer for industry use. 

In 2011 Developed new technology with single compressor having multiple circulation systems (can reach to -80 degree with single compressor) 

Upgraded the second generation of refrigeration and heating dynamic temperature control system.

In 2012 Single compressor having multiple circulation systems is applied in production of SUNDI-4, SUNDI-5, SUNDI-6, and SUNDI-7, SUNDI-8 and LT series.

Upgraded the second generation of refrigeration and heating dynamic temperature control system for the second time and developing the third generation of refrigeration and heating dynamic temperature control system.

In 2013 Developed new product one operating multi refrigeration and heating temperature control system(the third generation of refrigeration and heating dynamic temperature control system).At the same time  testing the large capacity of ultra-low temperature freezer.

In 2014 Developed with large capacity of ultra-low temperature freezer which used for industrial production,new goods will be research.And it will be launched in the market soon........
