- More details
Reliable domestic hot water – all day long!
Vitotrans 300 is a packaged high-performance, high-output DHW heating station, designed for commercial applications requiring high volumes of domestic hot water. DHW flow rate: 5 to 180 GPM.
DHW heating unit designed for applications requiring large volumes of hot water, such as hospitals, resorts, hotels, etc.
One Vitotrans 300, S3HA-60 could replace the need for fourteen 119 USG DHW tanks.
BACnet (IP) communication for easy integration into building management systems.
And packaged solution for minimum footprint and hassle-free installation.
Peace of mind
Double wall heat exchanger(s) with leak protection option available (D3HA Series).
Can be installed into new or existing hot water heating systems.
Endless domestic hot water for commercial applications
Vitotrans 300 is a compact, preassembled and self-contained domestic hot water (DHW) heating station, designed to provide large volumes of instantaneous hot water to commercial applications, such as hotels, resorts and recreation complexes, hospitals and industrial facilities. Vitotrans 300 works seamlessly with any new or existing hydronic heat source to provide a reliable and consistent supply of endless hot water at flow rates of up to 180 GPM.
Vitotrans 300 eliminates the need for dedicated DHW heating boilers, batteries of direct or indirect-fired DHW tanks, or cascades of tankless water heaters for maximum cost savings.
The unit's compact footprint (approx. 14 ft.²) makes the Vitotrans 300 an ideal choice for limited-space installations, preserving valuable real estate for other purposes.
In multi-heat exchanger models, each heat exchanger can be individually isolated and serviced without interrupting system operation.
The Vitotrans 300 is capable of producing DHW at over 96% efficiency. Furthermore, Vitotrans eliminates the need for a separate system dedicated to DHW production, thus lowering total energy requirements of the facility, resulting in a long-term increase in overall system efficiency.
Maximum life expectancy
The burner-less design of the Vitotrans 300, combined with a descaling pump result in low thermal stress and sediment build-up within the heat exchanger(s), ensuring minimal maintenance and prolonged service life.
Easy installation and service
The Vitotrans 300 is designed to accommodate a large ΔT, allowing quick and easy installation into any new or existing hot water heating system, requiring minimal piping or wall penetrations. All enclosure panels can be easily removed for service giving access to the entire unit for fast, efficient service. In multi-heat exchanger models, each heat exchanger can be individually isolated and serviced without interrupting system operation.
