A compact flexible boiler packed with innovation High efficiency, low emission High pressure steam, low pressure steam Hot water & Thermal fluid w/ large temperature difference Small footprint, easy installation and start-up Engineered for optimal heat transfer and no thermal stress
Novatherm PowerFlex series
DeltaFlex
THE DELTAFLEX boiler is designed for a smaller capacity and footprint but is packed with innovations.
THE DELTAFLEX comes as a complete, shop-assembled package requiring minimum work to install and start-up. Its main downcomers are internal, meaning they require no “on site” insulation.
THE FURNACE, THE BOILER TUBE SECTION, AND THE BURNER HEAD are easily accessible from one side through insulated inner panels, resulting in much easier inspection and maintenance and shorter downtime.
FOR EASY MAINTENANCE, we use ferrules to connect tubes to drums and ceramic fiber insulation for easier handling and longer service life.
COMPACT, EASY TO INSTALL, EASY TO MAINTAIN
Large steam drum with steam
separator producing exceptional steam quality of 99.5%.
Two large cold down comers provide better natural
circulation preventing overheating and
increasing boiler life expectancy.
Tangent tubes form baffle free gas
passes improving ease of service and
inspection.
Staggered tube profiles allowing for a more efficient heat
transfer and minimum thermal stress.

HIGH EFFICIENCY, LOW EMISSIONS - Combustion efficiency guaranteed from 80 to 82% firing gas. Fitted with up-to-date low-NOx burner technology, the DeltaFlex will comply with your local emissions regulations.
FLEXIBLE BOILER - The DeltaFlex is versatile and perfectly suited for many applications. It can be configured to generate hot water or steam at very high pressure, or to heat thermal fluid with a large temperature differential.
BAFFLE FREE GAS PASS for ease of inspection and maintenance.
SUPERIOR HEAT TRANSFER AND WATER CIRCULATION - The DeltaFlex tubes are arranged in a staggered pattern, providing a more efficient heat transfer and overall boiler efficiency. Each pass slopes upward to ensure, together with the two insulated internal downcomers, a quick and efficient internal water circulation, promoting better heat transfer and, most importantly, an homogeneous temperature gradient throughout the boiler which eliminates damage caused by thermal stress.
HIGH-QUALITY STEAM - The DeltaFlex steam drum is sized and fitted with innovative internals to provide a large steam release area and water volume, resulting in a stable water level and production of very dry steam at all load.
