The chart below lays out the available lengths for the 460V, unheated electric STD2 Series of air curtains. The highlighted row is specific to this item. Simply choose your length based on your installation needs. It is recommended that a door switch be used with the air curtain. Door limit switches automatically activate and de-activate (start and stop) the air curtain when the door(s) open and close. A controller that offers time delayed control reduces the cycling of the air curtain motors in high traffic areas (10+ times/hour). This type of controller will delay the unit from turning off when the door closes. They can usually be set from 6 seconds to up to 20 minutes. Available door switches and controllers for the STD2, 460V unit include:
- Door Limit Switch 99-014 - Combination mechanical switch, no time delay, 250v, 1HP Max
- Door Limit Switch 99-124 - Commercial, floor mounted reed switch, no time delay. For motors up to 1HP. MCPA-3UG control panel is required
- Door Limit Switch 99-125 - Commercial, surface mounted reed switch, no time delay. For motors up to 1HP. MCPA-3UG control panel is required
- Controller J0022 - Commercial low voltage controller, 208-277V, 1Ø, adjustable time delay, with commercial plastic surface mounted door limit switch (field installed)
When you add a door switch, your unit will automatically turn on when the door opens and off when it closes. Plus, it will continue running for a configurable period of time.
Additionally, a motor control panel and a separate relay or relay with time delay is required to operate the STD2 air curtain. The motor control panel is a separate, externally mounted control panel and is available for each size Air Curtain.
