EDH heaters
- For the pre-heating hydraulic oil, heating oil or other hard-inflammatory agents.
- The fluid to be heated is lead through a heating element bundle with the aid of deflection segments.
- With a pre-predetermined minimum flow rate a sufficient flow velocity is reached thus avoiding the carbonisation temperature of the fluid.
Product Features
- Mounting position can be either vertically or horizontally. Vertically: Provide electrical connection on the top.
- Heating capacity 0 - 90kW
- Thermostat: 0 - 90ºC (Not EDH-500)
- Temperature limiter at 100ºC (Not EDH-500)
- Surface loading: 2 W/cm2
- Supply voltage: 3 x 400V
- Housing: St37
- Heating elements: Stainless Steel 1.4541 (AISI 321)
Option
- Surface charge: 1 W/cm2 (recommended for viscosity >1000 cSt)
- Water and water mixtures
- Temperature regulation (Not EDH-500)
Maximum operating pressure = 16 bar - Higher operating pressures available on request
Operating temperature = 0 - 95ºC
Recommendations
- Installation of flow control
- Avoid after-heating effect / Make sure that deflection segments are cooled down (let the medium flow further, approximately 15min after device is turned off)
Caution: Incorrect installation can lead to damage of the oil pre-heater.
