■ Inlet Water Bypass—provision for total water bypass directly into the tower collection basin during cold
weather operation.
■ Hoistable Steel Grillage—allows assembling tower at grade on temporary supports and hoisting
into final location.
■ Fire Retardant FRP—flame spread rating of 25 or less per ASTM E-84.
■ Control Systems—ranging in sophistication from standard fan starters and disconnects to
Programmable Logic Controllers that work in conjunction with your building or process system.
■ Variable Speed Drive—the ultimate in temperature control, energy management, and
mechanical equipment longevity
■ Electric Basin Heater Package—maintains collection basin water temperatures between 4°C
and 7°C during tower shutdown.
■ Vibration Limit Switch—shuts down the fan motor if excessive vibration occurs.
■ Solid State Water Level Control Package—monitor basin water level with solenoid-valve water
makeup. Configurations include makeup along with high and low water level alarm and cutoff
and electric basin heater cutoff.
