Biasi Oil Fired 3Pass Boiler A 3-pass boiler design is the most efficient way to get the maximum amount of heat from the fuel, since it contains three times as much interior surface area (compared to a single-pass boiler) to extract heat from.	Technical Advantages Gas or oil burner compatible Easy access swing door May be direct vented with no flue required; can be direct vented outdoors with optional direct vent kit. Low water content boiler heats up faster with less fuel Efficient 3-pass heat exchanger boiler design GG20 cast-iron construction for superior heat retention and durability ASME, UL, and IBR listed 58 psi cast-iron construction
The B-10 boiler systems have been heating residential and commercial buildings throughout the world for years. It has proven its fuel efficiency and durability in countries where fuel can cost up to four times as much as in the U.S. The same fuel saving technology is now available here in North America. With the three pass boiler design and low water content, heat is quickly supplied for your heating zones and hot water needs. Combined with an outdoor reset control, you can achieve a fuel savings of up to 40% over conventional single pass boilers. You will also have peace of mind since the B-10 boiler package complies with ASME and UL standards and is IBR rated. The B-10 boiler system is the cost-competitive heat and hot water system of choice.

The new Zero ODP Drop-in Replacement compatible with all lubricants

HCFC 22 is a controlled substance under the Montreal Protocol and European Regulation and will be phased out on a global basis with all other HCFCs. HCFC 22 is already banned in Europe in most new equipment and is subject to a rapidly tightening cutback schedule. It is, therefore, now time to consider the options for replacing HCFC 22 which will become restricted in availability as these cutbacks come into effect.

RS-44 provides a low cost and easy solution to replacing HCFC 22 by avoiding a costly and technically unsatisfactory retrofit situation. By definition, any replacement for HCFC 22 must have no ozone depleting ability so that, in contrast to replacing CFCs (e.g. R12, R502) where there were 'interim' blends available (largely containing HCFC 22) enabling the existing lubricant in the system to be used, this is not an option when seeking to replace HCFC 22. R424A has a zero Ozone Depletion Potential, a similar performance to HCFC 22 and can be used with all types of lubricants.

Comparison with HCFC 22

Higher Coefficient of Performance Lower discharge temperature Zero Ozone Depletion Potential Non-flammable

Lower discharge pressure Similar capacity Compatible with existing oils No hardware changes needed
