4MD Pre-Order

The 4MD... the Doctor is in the house!  Inspired by the CHAMPS Driftwood piece, but in a compact size.  This is one of the last batches of thermal liberators to be produced by Herbaltherm.  With this known, each unit will come with a DIY repair kit and videos will be provided to aide in repair. A community at herbaltherm.freeforums.net has also been created so that the 400 folks that purchase a 4MD, 2ZM and 4MI will have a place to congregate in years to come.  To learn more see the Lean Start-Up blog post.  Thanks to all that help me write this last chapter with these 3 projects allowing me to make a few fine things for some real fine friends :)

One of the big challenges with full convection systems is that laminar flow and cold load chamber walls make for uneven temperature distribution.  This is evident by a "hot spot" in the center of the load.  After ten years of R&D we have fixed both of those problems with the 4MD.  The heater glass is heated (don't sick yur finger in the hole!) so it imparts passive conduction to the load chamber.  Like the 5DT, the 4MD will feature a flow disruption pall array to both add turbulence to the air, as well as optimize the flow path.  These two innovations combined with a massive 12 V  heater inspired by the 2ZM have made this a best of a thermal liberator!

The Herbaltherm desktop series will standardize on a variable voltage power supply or 2 such that the power supply does not need to be purchased with future units to save a few bucks.  There are a number of improvements like replaceable glass, mica wire pass-through, thicker wood and bigger air gap for added insulation, mica heat deflector plate... and did we mention the glass balls

The 4Mi wood selections are: Cherry, Cherry select, Cherry two-tone, Maple, Maple select, Lacewood faced cherry, Purple Heart faced cherry: Leopard, purple heart, canary striped front: Maple, purple heart, leopard, sepele striped: leopard, purple heart, paduk, zebra, maple striped, Walnut, Maple Walnut, Walnut, cherry, walnut, and walnut maple. Exotic wood bottom caps will be purple heart, paduk, zebra and leopard with cherry and maple as the domestic options.  Bottom caps will be selected to best match the design. Note that the pictures are raw wood and will become more vibrant with deeper grain. (see cherry picture of raw cherry wood next to finished unit for an example.

The prototype has made it way through the beta testing with rave reviews and the production unit will be out to the testers this week.  Get all the technical details and watch the design and manufacturing process on herbaltherm.freeforums.net
