The BNZ Series of water - oil coolers provide an efficient way to cool hydraulic fluid utilizing shell and tube technology. The design consists of an outer housing
shell and a tube / fin bundle known as a “stack”, which fits inside the shell. Hydraulic fluid to be cooled is circulated through the housing shell and passes across
the cooling fins which transfers the heat to the cooling tubes in the stack. Cooling fluid, being typically water or water-glycol, flows through the cooling tubes
running through the stack to carry the absorbed heat away. This rugged design offers high heat removal in a compact package. A large variety of cooling capacity
sizes, port options and material choices are available to tailor the optimum cooler to meet specific application needs. For more application information, refer to
the “Application Guidelines” section.
