Productbeschrijving

De Defro chamottesteen is een hoogwaardige, hittebestendige keramische steen voor de verbrandingskamer van klassieke vastebrandstof- en houtvergassingsketels van de types DS 20 kW en DS II 25 kW van DEFRO. Hij zorgt voor een gelijkmatige vlamgeleiding en hoge thermische veiligheid in de ketelwerking.

Wat dit product bijzonder flexibel maakt:
✔ Je kunt alleen de Primaire steen bestellen – bijvoorbeeld als de vlamgeleider versleten is.
✔ Je kunt alleen de Secundaire steen bestellen – ideaal bij schade in het gebied van de secundaire luchtopeningen.
✔ Of je kiest voor het complete set met beide stenen – perfect voor een volledige vernieuwing in één keer.

💡 Primaire steen: Chamottesteen vlamgeleider – verantwoordelijk voor de primaire verbrandingsluchtgeleiding in de ketel.
💡 Secundaire steen: Tweedelige chamottesteen met openingen voor secundaire luchttoevoer – ondersteunt de naverbranding.


Varianten & Keuze

  • Primaire steen – los

  • Secundaire steen – los (bestaande uit twee halve schalen)

  • Set – Primaire & Secundaire steen – compleet chamottestenen-pakket

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.

Treats and plenty of ball throwing with these doggie toy
Size: Medium (2.5"), Style: Fetch Pack 1
I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!

My Female GSD loves
Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
Shasta is my smallest. Six in December (2025) along with her brother. She’s 100 lbs and outside, completely ball driven see last picture. Don’t let the size (2.5”) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect! Shazzy was born with several ortho issues. I don’t throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, she’ll catch the ball mid air. The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them! Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because she’d look day and night if we actually ran out!! 🙏✝️👍🏼👍🏼

Holds up pretty well.
Color: Green Helix, Size: Medium
Holds up against my velociraptor! Much better than some of the other holey balls that get torn apart quickly. I think this is a great idea to reuse old shoe soles into toys for the heavy chewers like heelers. I would like to see a large ball like 10-12 inch diameter, so they can push and throw it around.
