Overview: The document provides detailed information about electrical oil
preheaters manufactured by FUNKE Wärmeaustauscher Apparatebau GmbH. These preheaters are designed to optimize machine-tool efficiency by maintaining oil at a selected temperature, thus minimizing energy consumption and wear.
Specifications: FUNKE offers a range of 11 sizes of
oil preheaters with heating power from 3 to 100 kW. The preheaters are suitable for heating oil, flame-resistant liquids, and emulsions, particularly in outdoor areas and test stands. The operating mode involves media flowing around u-shaped heating rods, ensuring adequate flow velocity and heat transfer.
Quality and Standards: Each unit undergoes quality checks and pressure tests. Additional tests can be conducted according to various international standards, including the Pressure Equipment Directive 97/23 EC, ASME, TEMA, API, GOST, and others. FUNKE is ISO 9001:2000 certified and authorized for ASME U-Stamp and HP0/DIN EN 729-2.
Applications and Advantages: The preheaters are crucial for systems where oil viscosity increases at low temperatures, potentially causing high pressure losses. Preheating ensures easier system start-up and integration into hydraulic systems with bypass flow cooling and filtering. The design includes a temperature limiter and electro-junction box for safety and efficiency.
Technical Data: The document includes a table detailing the type series, heating power, minimum oil flow, operating pressure, and temperature, along with dimensions for each model. The high-temperature unit can reach up to 200 °C, with special designs available for specific requirements.
Global Presence: FUNKE operates globally with facilities in Germany, China, Russia, and India, supported by over 30 sales and service partners worldwide.
