KVEc 1/3
product data sheet KVEc
The ultracompact KVEc heaters offer highly effective heating power for processes with water or similar media. Important development targets were minimised footprint and perfect cost control without compro-mise on quality and reliability and serviceability.
DesignThe KVEc series is based on our renowned KVE series. We use high-quality centrifugal pumps (wet runners and dry runners). All components can be exchanged with standard tools.
ElectricsDue to the fl exible design, the units can be adapted to any operating voltage between 230 VAC and 690 VAC. The compact dimensions require external installation of the main fuses.
Operating pressure 10 bar in standard design/16 bar in HP design
Operating temperatureMax. 95/100 °C
Heat transferDue to the perfect hydraulic fl ow around the heating elements, the medium is gently heated to the specifi ed temperature. The surface load (W/cm2) is approximately 8 W/cm2.
MaterialAll components in contact with the medium can be made of material suited to the application. By standard and with short delivery times: P265GH (mild steel) and 1.4571 (stainless steel). Other materials are available on request.
Controls (ELWA)The compact control box contains contactor for the heater, transformer and fuses for the pump and the temperature controller and temperature safety limiter. The basic version is designed for remote operation without local switches and indicators.
Options> electronic temperature controller (with display)> safety valve> non-return valve> local operation with switch and indicator lamp> coupled dry runner pump> thermal insulation (softshell)
Typical applicationsThe series KVEc heaters are the perfect choice for preheating the cooling water circuits of small and mid-sized diesel engines. Further possible areas of application: Heat source for industrial processes/building heating (booster/legionella cycle).
