Automated Vent Systems

 

Strong, durable and long-lasting, Wadsworth Integrated Vent Systems provide you with a precise greenhouse environment whether you have a retail or growing operation. Efficiently control the air temperature for more profitable plant growing and/or a more comfortable shopping experience for your customers.

Wadsworth Vent Systems can be controlled from a thermostat or a state-of-the-art computer system like the STEP Series controls.

 
 
Four steps to selecting the right vent automation system:

1. What size gear motor?

2. What shaft size?

3. What type of vent control?

4. What length of rack?

1. What size gear motor?
VC-100A Motor
  • 1/20 horsepower - T.E.N.V.
  • 115 volt / 60Hz. / .68 amp
  • Ball bearing motor
  • Copper windings – insulation call B
  • Thermal overload protection – automatic reset
  • Quick reversing
  • 1600 R.P.M.
  • Continuous duty
  • Lifts up to 75' of 48" polycarbonate roof ridge vent
  VC-2000 Motor
  • 1/5 horsepower - T.E.N.V.
  • 115 volt / 60Hz. / 2.5 amp
  • Ball bearing motor
  • Thermal overload protection – automatic reset
  • Quick reversing
  • 1600 R.P.M.
  • Continuous duty
  • Lifts up to 325' of 54" polycarbonate roof ridge vent
2. What shaft size

Determine the size of your drive shaft. Measure the outside diameter of the shaft.

 

3. What type of vent control?

Incremental (I)
  • Opens in increments: 1/4, 1/2, and full open
  • This is a master control. If placed in the center it can have up to six 2R Slave Units (three on each side).
  • Primarily used with STEP50, STEP500, M-1608 or thermostats.
  • It can be used with a computer control, like the EnviroSTEP and it will open in proportions. The computer overrides the incremental control command.
  • Growers who are upgrading to a computer control can use existing incremental vent controls, but if ordering a new vent automation system, order the LST control with computers.
  • External limit switches.

Limit Switch with Transformer (LST)
  • Opens proportionally with a computerized control.
  • This is a master control. If placed in the center it can have up to six 2R Slave Units (three on each side).
  • Primarily used with EnviroSTEP, VersiSTEP and microSTEP/SA computer controls. It can be used with any computer control for proportional vent movement.
  • It is used with the MiniSTEP to move vents from full open to full closed.
  • If used with STEP 50, STEP 500, 4-stage control or thermostat it does not open in increments, only full open to full closed.
  • External limit switches.

Slave Unit (2R)
  • Used with a master control—movement follows the master unit.
  • Used with Incremental control it opens in increments: closed, 1/4, 1/2, and full open.
  • Used with LST control it opens proportionally, following the master unit.
  • If the master control is placed in the center it can have six 2R slave units (three on each side).
  • External limit switches.
