About us:
j&w Cleaning Systems was founded in may 1998 as a spin-off from the company jaresch&wegener (founded in 1932).
Due to decades of professional experience in the field of engineering and manufacturing steel structures and fan rings for any type of heat exchanger plant, a new idea arose in the 90's - the idea to design cleaning systems for enourmous fouled heat exchangers.
Meanwhile j&w has become the technological market leader on this sector.
In addition to the designing and manufacturing of permanent installed cleaning systems, j&w also offers a cleaning service with its own staff in Europe and in South Africa.
Worldwide we cooperate with distribution partners who offer the
patent-pended j&w cleaning systems and service .

Shanghai Shenglin is a professional supplier in China specializes in refrigeration units and parts. Now we have two factories. One is mainly manufacturing condensers and evaporators, the other one is mainly manufacturing central air conditioners like roof-top air conditioners, precision air conditioners and air handing units. Both of our factories are ISO certificated.

Our condensers and evaporators can be widely used in air conditioners, heat pumps, fan coils, air handing units, drinking machines, ice makers, dehumidifiers, laser machines, welding machines and other area. We can not only manufacture copper pipe condensers and evaporators, but alsomanufacture stainless steel pipe and aluminum pipe condensers and evaporators.

Our rooftop air conditioners are easy to be installed and maintained. As they are installed on the top roof, so they will not spare the room space. They are weather proof and have high efficiency.

Our precision air conditioner can control temperature in ±1℃ and humidity in ±5%. It can be used in data center and telecom base station. Most parts are world famous brand.
