Compact powerhouse for utility and industry
The Senator+ is the ultimate standing central heating system for utility and industry. With its large capacity and the standard option to cascade a wide range of high capacities can be realised within limited space.
Small flue-gas diameter
The Senator+ flue-gas outlet has a diameter of only 180mm*. This is possible because the boiler is equipped with two robust ventilators. This small flue-gas diameter ensures that the boiler is very suited for renovation projects.
*Standard Ø200 mm flue-gas material is offered in quotations, including a 180/200 reducer.
Reliable
Due to the design of the boiler and the use of high-quality components the Senator+ is very reliable. The double lined combustion chamber, the gas block and the automatic burner ensure for a reliability; as if two devices have been installed.
High efficiency
The Senator+ has the certificate GASKEUR HR 107 Heating and clean combustion. Plus, the Senator+ is equipped with a modulating range of 1:8. This option to modulate, in combination with the correct control equipment makes the boiler very efficient. This range ensures that demand and supply can be very well aligned.
Easy installation
The Senator+ is designed so it can be installed easily. A Senator+ fits through the most common doorways without any problems. Furthermore, the boiler is equipped with two wheels, so positioning the boiler in respect to the installation is very simple. Due to the small dimensions of the device it is possible to install a large capacity on only a few square metres.
Incorporated cascade regulator
The Senator+ has an incorporated option to switch as many as six boilers in cascade. This function is a standard part of the boiler software.
Building management system
The Senator+ boiler, based on 0-10 volt control, is suitable for all common building management systems.
Weather-dependable regulator
Due to the incorporated weather-dependable regulator the Senator+ can also be controlled on outdoor temperature with the use of an outdoor sensor. This provides a constant temperature for the whole building, both in summer as in winter.
