Defro Tegenstroom-warmtewisselaar ERV 500 (recuperatief)De ERV 500 recuperatieve tegenstroom warmtewisselaar is ontworpen voor efficinte warmteterugwinning in mechanische ventilatie en warmteterugwinningssystemen. Dankzij de tegenstroomtechnologie wordt warmte uiterst effectief overgedragen tussen de afvoer en toevoerluchtstromen, wat resulteert in een hoog rendement en een laag energieverbruik. Als enthalpie warmtewisselaar (ERV) draagt de ERV 500 niet alleen warmte, maar ook een deel van het vocht over

De ERV 500 recuperatieve tegenstroom-warmtewisselaar is ontworpen voor efficiënte warmteterugwinning in mechanische ventilatie- en warmteterugwinningssystemen. Dankzij de tegenstroomtechnologie wordt warmte uiterst effectief overgedragen tussen de afvoer- en toevoerluchtstromen, wat resulteert in een hoog rendement en een laag energieverbruik.

Als enthalpie-warmtewisselaar (ERV) draagt de ERV 500 niet alleen warmte, maar ook een deel van het vocht over van de afgevoerde lucht naar de verse toevoerlucht. Dit helpt om een comfortabele luchtvochtigheid in de woning te behouden, vooral tijdens de wintermaanden wanneer de binnenlucht vaak te droog wordt. De speciale membraantechnologie voorkomt condensvorming en beperkt warmteverlies door waterdamp.

De warmtewisselaar is vorstbestendig, onderhoudsvriendelijk en gemaakt voor langdurig gebruik zonder overdracht van verontreinigingen tussen luchtstromen. Hierdoor is de ERV 500 een ideale oplossing voor energiezuinige en comfortabele ventilatie in residentiële toepassingen.

Belangrijkste voordelen

  • Zeer hoog warmteterugwinrendement

  • Overdracht van warmte én vocht voor optimaal binnenklimaat

  • Geen of minimale condensvorming

Great product! Durable, chewable, awesomeness!
Color: Grilled color, Color: Grilled color
Very well made and durable. My dog hasn't left them alone since i opened them. Hes been at it for about 45 minutes straight now! Lol. He's an avid chewer. He will chew thru and fabric or cloth toys in less then a day. But these are what he really likes because they take time to chew apart. The shapes, are great, because one he props up with his paws and chews and it seems like it's easy to grip for him. Thru are hard so if you have hard floors it can get a bit noisy when he drops them. Over all this is a great product. Safe, chewable, long lasting, fun shape looks real to him (i think lol), Me and my dog Lucky are both happy with his new toys!

Amazingly great product!
Color: Grilled color
I’m not just saying this, ok, this is not hyperbole: this is THE best nylon bone for chewing that I have ever purchased. And you get TWO of them for relatively less expensive than most chew toys give you one! I have 2 golden retrievers, and if you know goldens, you know that they are some of the most relentless and powerful chewers around. So I can’t give them almost any toy other than rubber stuff or it will be destroyed in a period of time that doesn’t make it worth it. One of them even figured out how to destroy a supposedly indestructible toy made out of kevlar! She was able to get into it through the seam, which is not kevlar ha ha. Anyway, I digress; I never even considered nylon chews because they suck! Usually. Usually my dogs in the past have lost interest with them in less than a day. I took a chance on these mainly because of the novel shapes, the fact that they give you two, and the low price. Both my goldens LOVE these! Not just for one day, but going on weeks now! I don’t know if it’s the flavor or what, but I will see them gnawing on one of them at some point every day. And they CAN’T destroy them (I knew nylon was good for that, but it was the “who cares” attitude of my previous dogs toward nylon that kept me away). Both the “ribs” and “steak” (quite clever) are a bit worn on the edges now, but they look like they will be around for years. You can’t go wrong with this product (unless for some reason your dog does not like the flavor, but the flavor seems to be what draws my dogs to them). I highly recommend this (these) as the most cost-effective chew toy I’ve ever purchased.

Great for larger dogs
Color: Grilled color
I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!
