Cost - It is typically less expensive to use two
regulators that were part of a larger bulk shipment and therefore purchased at a savings.
Convenience - There is a good chance that the regulators used
in the manifold are already in stock at the retail location. Larger capacity regulators
are almost never in stock at either the retail or distributor warehouses.
Comfort - Some uncertainty can arise when service personnel
are asked to install complicated control lines or work with bulky, heavy regulators. There
should be no additional training required to install or service equipment that is
already handled everyday.
Capacity- By installing two regulators in a manifold, the
new system capacity is usually more than that of a single, large regulator. This can allow
the customers to add future gas load without the need to add any more equipment.
Constant
- The flow of gas may never have to be
interrupted as a result of regulator service requirements. In a properly installed
manifold, the regulators can be isolated and serviced without turning off gas
supply.
