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

Het vervangen van losse stenen verlengt de levensduur van je ketel en voorkomt onnodige reparatiekosten.

My new favorite summer sandal!
Size: 8.5, Color: Bay Fog
I am loving these shoes so far this summer! The color is so cute, perfect for a light summer palette. It's the perfect light purple that doesn't make me look pale or washed out. For reference, I have fair to light neutral skin tone. They are SO comfortable - a little too comfortable for a shoe, it's more comfortable than my ugg slippers! They do take a second to put on as you have to either force your ankle in without unstrapping the back - don't judge me - or undo them. Thankfully they have a strap to help get them on easily. I love these shoes. I am a medium width, but I think these have some wiggle room since both the straps are velcro and adjustable somewhat. They are easy to walk in, hold onto the foot, have been more balanced than some others I have had in this platform style, and are very cushioned to walk in. Slight arch support to me but I have somewhat high arches so if you are more flat footed or standard arch these will give you even better support. Really impressed with these. They are more casual but work with many different outfits from sundresses to jeans. For me, these were a great buy and I will be wearing them all summer.

Style, Comfort
Size: 9, Color: Sand
If I could give a Ten Star review, I would. Hands down the most comfortable pair of sandals I have ever owned. I wore them 16 days straight while touring Italy. Comfortable and goes with all of your outfits. They pack well in a suitcase too. Light weight.

Wonderful
Super comfy and easy on and off, yet stylish imo! I could walk miles in these as a 56 yo and have worn them for three years! I hope they never stop making them. The only tweek I would suggest is to cover the footbed with leather or suede not cloth so they would last longer!
