We're a construction business in the UK focused on building energy efficient residential buildings which always require very well designed and installed mechnical ventilation systems. We've used a number of suppliers in the past and Sichuan Guigu Renju Technology was one of the best. They have a very capable and professional design team that can customize systems to our requirements and accurately estimate the components needed to achieve designer system performance. The quality of the goods supplied was top class, I was particularly impressed by the anti-bacterial pipe and fittings that are very easy to install and create a professional high quality finished product. The MVHR units are also great, available in high performance and effciency models with simple controls and easy installation. Similarly impressive was service by Irene - exceptionally professional, very quick and accurate advice and willingness to help regardness the complexity of the project. Thank you very much!

A very well made product. good spec, thought through solutions. They shipped it and prepared it very well for me. All the best from Norway.
