The AVT modulating valve: Advantage Engineering pioneered the modulating valve technology as a standard, and after more than 30 years, Advantage Engineering is still the only company offering this at no extra cost, when comparing prices with competitive units. Competitive units, at similar prices, offer a solenoid valve as standard, and offer the modulating valve for at least a $500.00 adder. Why is this significant? The modulating valve offers the following advantages: Continuous cooling vs slam cooling: the solenoid valve shocks the system with “water hammer inducing” spool shifts, while the modulating valve is a ball valve that gently finds an equilibrium and gently bleeds cooling water through the system at a steady, consistent rate. Much higher cooling water gpm: The cooling water injection capacity of a 1/2″ modulating valve is far greater than for a similarly sized solenoid valve. The 1/2″ modulating valve has a flow roughly equal to a 1″ solenoid valve. This produces more cooling capacity with an Advantage Engineering LE or HE unit, than with a similarly sized competitive unit equipped with a solenoid valve. Energy savings: This is not widely discussed because it takes a large number of units to see significant savings. However, the savings are real, and significant as a percentage. See my post about the energy savings here.
Custom designed pump impellers:
The custom designed casing and impeller generates 20% more flow with the same horsepower as compared to many competitive machines.
Achieving about 20% more flow using custom impellers, combined with the greater cooling capacity of the modulating ball valve over a solenoid valve, allows you to use a smaller horsepower unit than competitive units for the same cooling capacity.
