External manifolds allow you to specify the amount of inlets and
outlets externally, meaning that this modification is visible from the
outside of your chiller.
Options are available ranging from 2-way to 10-way external manifolds.
External manifolds are useful in cases of multiple systems, or where there are multiple parts to one system. Needle
valves allow you to adjust and balance the pressure depending on the length
of hoses in the system.
