Glenwood Biomass Attachment (Optional)

The AT-800/AT-900 Glenwood biomass attachments are available in one size, but two styles.  The AT-800 has a rotary airlock and works best for burning hogged material, shavings, and sawdust, this style is featured in the Glenwood Industrial brochure.  The AT-900 has a sliding airlock operated by a compressed air cylinder,  this style is best for rough stuff such as construction and demolition (C & D) waste, chips from tree trimming companies, etc. Both biomass attachments are made durable components, as well as low speed operation are designed to provide many years of trouble-free service. Adding the Biomass Attachment to your Glenwood Boiler will allow you the versatility that no other boiler offers. Burn just about anything that will fit through the feeder and is dry enough to burn (25% moisture content or less); from Wood scraps to pallets, cardboard to other waste products that would otherwise cost you a trip to the dump!

The Glenwood Boilers offers the best boilers with the best warranty in the industry, hands down. Some manufactures offer a "Limited Lifetime Warranty" but when you read it you will find they are really "Pro Rated Warranty" some are barely worth the paper they are written on. Only Glenwood offers a NON PRO RATED 20 YEAR WARRANTY!  The closest you will find is a "5 year Bumper to Bumper with a 25 year Pro Rated Warranty" from Econoburn. Here is the Glenwood warranty for you to see for yourself, one simple page against rust through or failed welds.

* Use a Glenwood Biomass Dump Station to store large quantities of your biomass fuel and to continuously feed your Biomass Attachment.

**Biomass Attachment is only available for the models with a "P" after the model number.
