Shanghai Thermostat Factory Co., Ltd. is a professional manufacturer of refrigeration and air condition auto-control unit. We have more than 60 years history in this industry.
In 1985, STF cooperated with ALCO to produce T series expansion valves. We were the only Chinese company having the mixed infusing technology in expansion valve production. In 1993, Shanghai Johnson Controller Co., Ltd. Was established by us and Johnson to produce YK series controllers. In 1996, FDF-M diaphragm solenoid valve was certificated as National Grade New Product. As a high-tech enterprise, we get innovation fund from the government.
Our main products include solenoid valves, thermostatic expansion valves, sight glasses, filter dryers, pressure controls, pressure difference controls, temperature controls. We have gained approval for our quality control system in relation to international standard ISO9001: 2008. UL/cUL\CE & CQC approval can be supplied to order.
Products are widely used by Carrier, YORK, Trane, Dunhambush, McQuay, Mammoth, HANBELL, RefComp, Midea, Gree etc. And exported to America, Europe, Australia, Africa, Korea, Hong Kong, Philippine and Taiwan.
We stick to the development of specialization, give the best solution of localization and keep advanced in technology by continual innovation. We are always pursuing to be a leading enterprise in our area.
