Values are taken from the BEAR product catalogue for DH2800, DH3800, DH6500, DH8500, DH9500, DH10500.
Sound figures are values listed in the model source. Compare the same load, measurement method, distance and environment; request the complete test conditions when they are not stated here. Fuel-consumption and runtime figures are values listed in the model source. Request the load point, fuel or tank basis and test conditions for a like-for-like comparison; actual consumption and operating time depend on the operating conditions.

Questions about DH2800 – DH10500 Open-Frame Diesel Generators
Short answers for comparing this configuration before quotation.
Send your requirementsHow do I turn the range comparison into an order?
Name one DH model from the comparison and record its rated output, voltage, frequency and required outlets. Send that selection with the load list and destination country.
Can I compare the range using the largest output number?
Use the rated-output row for the selected model and keep maximum output separate. The 1.8–8 kW range describes several models, so the final quotation needs a specific model column.
