A WORK IN PROGRESS

MORE COMING This Week!

This gives you a better idea of scale. Not as big as it looks above:

Look at Our Newly Designed Fireboxes

When we decided to reinvent the wheel we knew that we had to start at the beginning and to us that meant the firebox. That is why at the heart of every HyProTherm furnace is a firebox unlike any other in the industry. Based on the knowledge that fire naturally rises and as it does it creates currents of air, we designed our HyProTherm fireboxes to maximize this potential. By utilizing the upwards drafting, funnel shape of a tornado, we have created a furnace that will burn coal or wood with almost no assistance from a combustion blower. Not only that, but our design will burn green sawdust, shavings, pellets, corn, or virtually any biomass that you choose, and due to its shape it will burn more evenly, completely, and with less stirring of coals. It is also the only firebox that allows for the use of the entire firebox. Because there is no flue pipe in the way and by utilizing our top loading feed door our fireboxes hold more than a comparably sized horizontal firebox (as shown below).

To Hyprotherm Manufacturing: Points of interest 1-4
 

1. In reviewing your request on your Forced Air Models and your commercial Hydronic models.

We know you feel a need for a desired product.

There are a number of materials that would work for your commercial hydronic and forced air stove. The high temperature fiberglass you cite below is one; there are also fiberglass and rock wool (which has a higher melting temperature) and the ceramic fiber materials (very high temp).

2. In our opinion you will need.

For the project you’re looking at I think max operating temperature and corrosion resistance would be important as well as workability. Blanket materials are more flexible than boards and blocks.

3. There are products you should not use for a thermal cycling unit.

Do not use a standard fiberglass insulation meaning the standard fiberglass your using is just metal building insulation with an R factor on it tested at 75 degrees, exceeding that perimeter heat factor the R factor drops dramatically

4. Results to following proper recommendations.

Based on our knowledge and the understanding of your needs, by using our recommendations and HVAC normal codes per efficiency, you should get the results you desire.

Thank you for your eagerness to do all you can to manufacture the best product available.

New HYPROTHERM

Improved Style Insulation

HyProTherm Standard Insulation Package

Based on the NAIMA formula thickness / k value = R value

Three inches of Knauf ET Blanket = R 10.71

+     One quarter inch Solar Guard = R 11.6____

HyProTherm side wall standard insulation = R 22.31

note: operating parameters, temp -10 deg, 5 mph wind, 150 deg operating temp = -1.6 deg

8.4 deg differences (wow) see chart below

Two inches of Morgan Super Wool Blanket

HyProTherm top standard insulation

note: operating parameters, temp -10 deg, 5 mph wind, 700 deg interface temp = 22 deg cold face temp

Features and Benefits

Excellent Thermal Properties

• Low thermal conductivity.

• Increase system efficiency and decrease fuel usage.

Low-Cost Installation

• Lightweight and easy to handle and fabricate.

• Flexibility makes them ideal for flat or irregular surfaces.

• Damage Resistant

• More resistant to abuse than standard ET Blanket.

• Tough and resilient.

• Resist damage in shipment, and during and after installation.
