Perfection, precision, innovation:The Kränzle therm hot water high-pressure cleaners combine a number of technical innovations from Kränzle that contribute towards reliable operation, the safety of the equipment and not least towards operating and servicing.
The Kränzle therm cleaners are extremely safe to operate, kind to the environment, clean and quiet.
The Kränzle therm HP cleaners represent the state-of-the-art in equipment and safety. | The therm combustion unit:
The combustion chamber, a completely new design by Kränzle, is designed for professional continuous use, and the excellent thermic efficiency rating guarantees low heating-oil consumption and low emissions.
The new optical flame monitoring device:
The models of the therm 870, 895-1 and 1165-1 as well as the new therm C series are equipped with an optical flamemonitoring device. A photocell is located right above the combustion chamber and connected to the central control electronics. When the photocell detects extinction of the burner flame despite uninterrupted fuel supply, fuel feed is cut off as fast as can be done while an error message appears in the thermostat display. |
The thermostat with adjustable burner performance:The models 895-1 and 1165-1 are equipped with a digital thermostat which now allows for 2 modes of operation:
Operation mode 1: Thermostat control Press buttons to pre-select °C target temperature.
Operation mode 2 : Burner performance Press buttons to pre-select burner performance in %. The burner will be switched on or off at a given frequency and in accordance with the defined target values.
Once the parameters are determined, operation mode 12 has an advantage over operation mode 1 in as much as temperatures can be kept steady at +/- 2 °C. This can even be achieved with marginal water quantities and at low temperatures as are, for example, required for animal washing. All of the last selected values are saved in the thermostat's memory.
The high-pressure cleaners of the 870-1 as well as the therm C/CA series are equipped with an analogue rotary thermostat (control range 30 °C - 150 °C).
The new safety fitting:The new safety fitting developed by Kränzle includes the pressure control valve for fully adjustable setting of the quantity and pressure of the water, and which also allows pressureless bypass operation. The safety valve continues to protect the equipment from excess pressure. The integrated flow indicator switches the oil burner off if the supply of water is too low, thus preventing the heating chamber from overheating. Two pressure switches control the burner and allow the system to be switched off automatically if the gun is closed for longer than 20 seconds. The pressure switches also restart the system when the gun is open. All components are tried-and-true, having been used successfully by the million in other systems, and are combined here for the first time in one service-friendly block.
