WhatmakesENVIRO-TEC®fanassembliesefficientistheuseofthreespeed,threewinding,permanentsplitcapacitor fan motors . The three speed motors are capableofdelivering threeseparatehorsepowerout-puts.Forexample,anominal1/2HPmotoratmediumandlowspeedswilldeliver1/3HPand1/4HPrespec-tively. This is the most efficient means of handlingreduced fan capacities .

Aquickselect terminalstrip isprovided forswitchingbetween motor speeds. An optional three positionrotaryswitchisalsoavailableforsimplifiedmotorspeedselection. Additional air balance of the fan can beachieved through field adjustment of an electronic(SCR)fanspeedcontroller.Theelectronic(SCR)fan

speedcontroller isofferedbyENVIRO-TECandhasbeenspecificallydesignedforcompatibilitywiththefanmotors.EachSCRalsoincludesaminimumvoltagelimiter for stall protection .

Thecombinationofathreespeedfanmotor,andelec-tronic SCR provides the most flexible and energy efficientmeansofbalancingfancapacitieswithvaryingfield conditions. This combination is preferred oversinglespeedmotorandSCRcombinationswhichcauseexcessivepowerconsumptionandhighmotorwindingtemperatures .

Each fan housing is specifically designed for com- patibility with the fan motors and internal pressure losses of the CDV cabinets. This design providesproper motor loading and maximizes fan performance .
