Greenhouse loovers, what do you do?

[Shadow_storm56]

Not sure if theres any other greenhouse growers on here but one thing we always had issues with is the little motors that open the vents/loovers. They are an ac motor that has tons of little gears and they push open the vents but when powers cut a spring makes the motor retract. They hum and grind all the time, die after a year or 2 and if theres the slightest bit of ice they won't close as theres no pull.

So I got really tired of this and I'm testing out using high end linear actuators. They are quiet, fast, pull 2 ways and should hopefully last. Anyone else do anything like this?

Check in to green house suppliers there are gas tube like gas shocks the work with the temp and will open and close with no power. I dont remeber who made the ones we use,

That would work yea anything but thoes aweful gear motors.

BTDT for 8-9 years, use 12 volt linacts, run off battery backup when power fails,run by $1 PIC that controls the greenhouse environment...

Sounds good!

It's what I use on my snowblower discharge deflector shute. I works good a bit slow but gets the job done from in the cab.

you can put a 'voltage booster' on them... I ran my SB def linact at 24 volts to make it run faster. Just be sure booster has enough amps for the linact you use.

These ones at 12v open and close in like 1 second

Progressive automations has some great stuff, if you want to keep it going a long time then every few years open it up and clean it, regreese it.
