Viessmann’s most advanced gas-fired boiler for commercial and industrial applications

New Vitocrossal 300, CA3 - Viessmann’s most advanced gas-fired boiler for commercial and industrial applications

Viessmann Manufacturing Company (U.S.) Inc. is proud to introduce the new Vitocrossal 300, CA3 gas-fired boiler, the latest addition to their commercial product portfolio of energy efficient heating solutions. The Vitocrossal 300, CA3 is the ideal solution for commercial and industrial applications. With multiple venting options and seamless integration in building management systems, the CA3 comes fully assembled and is easy to install.

The Vitocrossal 300, CA3 combines unparalleled flexibility with maximum efficiency, making it a smart investment choice for a new installation or an economical retrofit in multi-family, commercial or light industrial applications.  From buildings with narrow entrances and small mechanical rooms, to high altitude applications up to 10,000 feet, the flexibility of installation built into the new Vitocrossal 300, CA3 makes it the best choice on the market today.

The CA3 is equipped with the titanium infused stainless steel Inox-Lamellar heat exchanger surface which provides maximum heat extraction while maintaining a compact size; it features a maximum working pressure of 160 psi.  The smooth, corrosion-resistant surfaces on the heat exchanger allow condensate to simply run off; this is a “self-cleaning” process that ensures continuous condensing efficiency, reduced maintenance costs and longevity.  The large water content on the CA3 reduces wasteful burner cycling which increases system efficiency and overall durability.

The Vitocrossal 300, CA3 is currently available in four (4) sizes, from 3.5 Million to 6 Million BTU with inputs from 250 – 6,000 MBH and thermal efficiency of 96% on all models. In April 2017, 2 new sizes will be added: 2.5 Million BTU and 3.0 Million BTU.

The Viessmann-made Vitotronic 300, GW6C control manages the entire heating system and ensures economic performance and maximum comfort at all times. For larger systems, Viessmann offers custom boiler controls for virtually unlimited capacities plus additional options such as real time system loading, VFD pump outputs, BTU metering and efficiency trending.  Viessmann’s Matrix Cylinder Burner features a turndown ratio of  up to 15:1 and precisely matches the load per boiler, providing a quiet and environmentally friendly operation.

The Vitocrossal 300, CU3A is now available through Viessmann Wholesale Partners across the US. For more information, visit for more information.
