Home Forums General Discussion Technical Questions Stack effect or Wind effect

Anyone have issue's in taller buildings, with stack effect, causing the hall doors not to make? During our colder months, some of my lobby hoistway doors have a hard time closing. I've added a extra spirator in some instances. But this is more of a building problem, then a elevator problem. What are some suggestions or advice I could pass onto the customers

Definitely used to get wind resistance issues on the ground floor do to excessive air/ air conditioning pressure. I know the emergency egress doors in motor rooms can cause this as well. I also used to add extra turns on spirators and extra weight on door closers. I don't think there is any easy way to fix this, but check your rollers and guides on landing and car doors as well.

I have not used these yet but the SmarTork closers might be a good option: http://smartorkinc.com/
