HK-Serie

Product catalog summary

Overview:
The document provides technical specifications and operational details for the HK range of horizontal preheaters, which are indirectly heated using heat transfer oil by gas or oil burners. These preheaters are designed to increase melting capacity and ensure efficient operation.

Key Features:

Indirect Heating: Utilizes heat transfer oil to prevent local overheating, suitable for sensitive materials.
Two-Chamber System: Prevents cooling of preheated material when fresh material is added, ensuring a constant supply of melted material.
Reliable Sealing: The agitator shaft bearing is sealed against heat influences.
Heating of Agitator Shaft: Ensures efficient operation.

Models and Specifications:

HK800-1: Diesel oil burner, 10 kW power station, dimensions 2550 x 2700 x 1710 mm, weight 1310 kg (including thermal oil).
HK1000-1: Available with propane gas or oil burner, 3 kW or 10 kW power stations, dimensions 2950 x 3100 x 2110 mm, weight 1485 kg (including thermal oil).

Heating Methods:

Direct Heating: Offers high melting capacity but requires careful monitoring to avoid local overheating.
Indirect Heating: Provides uniform heat transmission, ideal for sensitive materials and relies on temperature control systems.

Technical Data:

Container Volume: HK800-1 has a gross volume of 880 liters, HK1000-1 has 1100 liters.
Power Station Engines: Options include a 1-cylinder gas engine and a 3-cylinder diesel engine, with varying capacities and dimensions.

Additional Information:
Custom sizes are available upon request, and the document is subject to technical changes and errors.
