Viessmann Climate Solutions UK has launched a new range of high-efficiency, low-emission, commercial gas condensing boilers with the introduction of the new Vitocrossal 200 CI3.
With eight output sizes from 80-640 kW and integrated-control cascade operation up to 5120 kW (eight units), the Vitocrossal 200 CI3 is described by the company as, “ideal for modernisation projects or buildings where space is limited.” Each unit is 750mm wide, occupying 1.07m2 of floor space – a reduction of 55% compared to previous Vitocrossal 200 models.
Thanks to its single or dual modulating MatriX cylinder burner with stainless steel heat exchanger, as well as an automatic combustion controller that contributes to ease of commissioning and increased operational safety, the Vitocrossal 200 CI3 has been designed to provide consistently efficient and high quality combustion throughout its service life.
The boiler has a standard seasonal efficiency of up to 94.8% and NOx emission levels below 27mg per kWh. A self-calibrating O₂ sensor automatically adjusts the MatriX burner to match different types of gas so natural gas and LPG can both be used. Additionally, the product is prepared for future changes in gas fuels.
The boiler has a large modulation range of 1:10, which offers greater efficiency at partial load. It also has two return connections as standard, so that there can be low- and high-temperature circuits if desired, with a lower temperature return for better condensation. The maximum flow temperature of the high-temperature circuit is 95 degrees Centigrade.
Installation and management
The units are supplied with integrated wheels and a practical transport pallet for enhanced manoeuvrability as well as a simplified electrical-connections terminal easily accessible at the back. Complete accessory packs are available for room-sealed installations and twin solutions and all components have been designed to be easily reached from both the front and the rear.
“This is a very user- and installer-friendly product that fills a market need for a really modern and efficient condensing boiler range that can cover heat demand up to 5.12 MW,” said Viessmann Technical Director, Christian Engelke. “We have customers that love the Vitocrossal 100 CIB so much they were previously installing 10-12 units to achieve their required output. Now they can meet their requirements with just two to four of these new models, which is much better as it reduces control complexity, spares requirements and is easier for the client. We’ve designed the Vitocrossal ranges to precisely meet the current and future needs of our customer base.”
