EDH Heaters

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.
