For steam to hot water for process or domestic hot water, Maxi-Therm offers different type of steam water heater upon your design and conditions of operation. A semi-instantaneous (MCU series) or a full instantaneous (VFFF series) steam water heater. Very compact with very low maintenance, only one main moving part; the control valve.
Energy conservation is unparalleled. There is no unit on the market more energy efficient than a Maxi-Therm for steam water heater application. It squeezes every practical BTU out of the steam and condensate by using not only latent heat out of each pound of steam but also sensible heat by cooling down the condensate under 200F. By doing so, we use directly to the heat exchanger up to 150 psig steam pressure inlet with our MCU series and up to 40 psig with our VFFF-D series.
Instantaneous packages can be wheeled through a doorway. Very easy install with only 5 main connexions: Steam inlet, condensate outlet, water in and out and electric power, in a very small footprint. All our system comes with an ASME stamp for high-pressure steam to avoid steam safety relief valve. Also, since there is no modulation on the steam side, the steam water heater doesn’t need a condensate pump station, no vent to the roof, reducing maintenance costs.
Different types of controls are offered, from self-contained mechanical blending valve to a complete control set-up including BacNet, Modbus communication.
We use an industrial heavy-duty piece of equipment including a robust shell & tubes heat exchanger, made in the USA, easy to clean for scale build-up and only one (1) gasket to be replaced if need to. We offer single wall or double-wall design and different type of material of construction: copper, Cu/Ni, stainless steel 304, 316 and even Food Grade configuration.
