Design advantages
The melting unit’s housing is made of thick aluminum sheet; the furnace tilts via an electric motor and gearbox, and the thyristor frequency converter uses an adjustable rectifier followed by inversion. The manufacturer states this gives one of the best price-to-quality ratios among induction furnaces, with a fast payback thanks to high output and low running costs; the design is compact and takes up little shop floor space.
The closed-loop LSN-40B cooling system
A closed-loop cooling tower with a water-based, sealed circuit protects the pipework from clogging, while circulating distilled water in the closed loop protects the power supply, thyristors, capacitors and induction coil from overheating. No large water reservoir is required — the system takes up little space and is easy to install and relocate; the circulation pump is 4 kW, the spray pump 1.5 kW, the fan 0.75 x 2 kW, the tower measures 3,365 x 1,250 x 2,480 mm, and it weighs 1,000 kg.
Configuration and price
The scope of supply covers the melting furnace and the cooling system; the final price depends on capacity and whether the closed cooling system is included — from $25,000 for the most compact set with no cooling tower, up to $55,000 for the 2 t set with the closed-loop LSN-40B system. Prices exclude logistics.
Frequently asked questions
Which metals can the KGPS-400 melt?
Steel, iron, aluminum, bronze and other alloys; the furnace is mainly used for melting copper, aluminum and other non-ferrous metals, where capacity can reach 0.05-3 t.
What does the closed-loop LSN-40B cooling system include?
Galvanized steel sheet, a 304 stainless-steel heat exchanger, an exhaust system, a sprinkler system, and a water collection and make-up system; rated cooling capacity is 240,000 kcal/h, flow rate 32 m3/h.
How much does the furnace cost without the closed cooling system?
The 2 t set without the cooling tower is $37,500; the 1.5 t set is $25,000 without it or $37,500 with it. Prices exclude logistics.
