Zur optimalen Klimatisierung und Belüftung des Gewächshauses ist ein automatischer Fensteröffner/-heber zwingend erforderlich. Dieser Fensterheber öffnet und schließt das Fenster bei Veränderung der Temperaturen im Gewächshaus.

Die Funktion ist über einen Druckzylinder gegeben, in dem ein Spezialgemisch sein Volumen bei Erwärmung sehr stark vergrößert und sich bei Abkühlung wieder entsprechend verkleinert - es arbeitet also im Ausdehnungsprinzip.

Produktinformation

HOKLARTHERM hat diese Öffner seit über 40 Jahren im Einsatz und handelsübliche Konstruktionen modifiziert. Dadurch haben wir einen hohen Sicherheitsstandard erreicht.Dieser Vorgang ist rein physikalisch und benötigt daher keinerlei elektrischen Strom. Durch Verstellen des Zylinders mittel Stellschraube, lässt sich die gewünschte Öffnungstemperatur regeln.

Diese Öffner haben sich seit über 50 Jahren bestens bewährt. Ein äußerst wichtiges Kriterium ist die Stabilität der Hebelkonstruktion und die Rückzugsfederkraft. Der Öffner wird oftmals auch starkem Wind ausgesetzt, wobei es bei zu „sparsam" ausgeführten Konstruktionen zu Beschädigungen kommen kann bzw. der Hubzylinder Schaden nimmt.

Bei der Montage dieser Öffner ist darauf zu achten, dass der kleinere Hebelarm möglichst parallel zum geschlossenem Dachfenster montiert wird, damit der vom Zylinder ausgeübte Druck die Schere auch öffnen kann. Ansonsten geht der Druck gegen "unendlich" und zerstört die Hebelkonstruktion, der Druckzylinder platzt oder die Kolbenstange verbiegt sich. Dies sind deutliche Anzeichen einer falschen Montage!

Wir bieten eine hochwertige Qualität zum fairen Preis. Für große und schwere Fenster (z.B mit ISO-Sicherheitsglas) wird eine große Kraft benötigt. Die Hublast eines Fensters entspricht ca. der Hälfte des Fensterflügelgewichts. 
Bitte vor Bestellung überprüfen, damit die richtige Auswahl getroffen werden kann.

 

Lieferumfang:

1 x Ersatzzylinder (schwarzer Kolben) für den automatischen Fensteröffner "Unitherm" (Lieferung ohne Gestell)

KEEPS MY ENERGETIC 1 YR OLD LAB BUSY
Size: Large
Anyone that has a field Lab knows you have to keep them busy which is difficult with the snow that won’t melt and the unusual -15 degree windchills we are having in NYC. Like others I’ve wasted so much money on various toys and puzzles trying to keep her busy and mentally stimulated. She either destroys them in minutes or won’t touch them. However, these with treats inside are fantastic. She loves the chicken flavor treats that go inside the ball. The treats for the holder are pricey but worth it so it keeps her busy for a while and she doesn’t get super hyper with cabin fever. Once I can get her back outside for longer periods to play and run off her excess energy I probably won’t be buying them on a regular basis given the price and that they only last a couple of hours given her strong jaws….Probably only for a special treat. However, for now they are worth every penny. The only con is they are difficult to get into the holder which is good so she can’t remove it.

We love em!
Size: Medium, Size: Medium
My dog loves these! I get a size smaller so it’s harder for him to eat. He’s 70lbs I get him the medium and it will last him 4 ish days. I also fuill the back with dog safe peanut butter, broken treats, and his food. This keeps him happy while I’m at work :) for reference he’s a gsd, and Australian shepherd mix. He never lets it get too far away, and proudly carries it along even when empty. He had one for over a year that just now started to break. They are very strong, great for chewers, and worth their weight in gold! When empty they also make them have the funniest faces🤣 again my dog had the first one for over a year before it started to rip. They are hardy.

Wrong item sent
Size: Small, Size: Small
The bento ball itself is great but the extra 16 treats that were sent as part of the purchase were the wrong kind. The picture used in the Amazon ad is the one shown in the left part of the picture I posted (dome shaped treats with a dog named Lacey in the picture), and what I received is shown in the right part of the picture (ridged treats with a dog named Bella in the picture). The problem with the Bella treats is that they are a bit smaller than the Lacey treats which means that they dont fit sugly into the bento ball. This in turn means that my little maltipoo gets them out of the bento ball in a few minutes. This defeats the whol purpose of the treat, and even worse this is a choking hazard for small dogs which makes the product unusable for me. FYI - I have never had this problem with the Lacey treats - they work great which is why I bought this product since this is what was shown in the picture. I sent a message to the vendor about this but have not heard anything back. Amazon offered to refund me half of the total purchase price if I sent back both the ball and the 7 of the 8 treat packages (I opened one only to discover this problem), which is also not great.

Fun, but short lived. Not tough enough for hard chewers
Size: Medium
Great idea. Wish it was tougher. My dog gets the branded treats out in ten minutes, and then destroys the ball in 30 minutes.

Best for my dogs
I’ve tried several coffee wood sticks for my dogs and these are by far the only ones they’ve liked and actually kept going back to! I have a terrier mix and a Pomeranian and both of them share it frequently!
