 MARPAK Difference

SPX Cooling Technologies is a world leader in the design, 
manufacturing and construction of cooling products.

The design and production of modular corrugated PVC media 
used in Marley cooling products is the same technology and 
expertise utilized in the development of the MARPAK product 
line of modular PVC media for biological wastewater treatment.

Since the origin of Marley in 1922, we have maintained a 
commitment to total quality in engineering, in customer service 
and in the close teamwork of our employees and representatives 
around the world. This long term dedication is what makes the
