HYDRAULIC UNIT
ECOMELT Control and Data System
Some features and messages that exist on ECOMELT Induction Furnaces are given below
Manual Tilting on Emergency Cases:
During energy cut-off situation, molten can be safely taken outfrom the furnace by hand operated lever hich takes place on thehydrulic unit.
COOLING SYSTEMClosed circuit converter cooling.
The converter unit is cooled with closed circuit de-ionizer the conductivityof water is kept at desires level, so that, corrosion of that causing
The converter unit is also cooled with plate type water/water heat exchanger.
Closed or open circuit Cooling Systems for Furnaces:As per customer’s request the furnaces are cooled by one of the followings; * ” Open Circuit “ with Evaporative type Cooling Unit * “ Closed Cicuit” with water/water heat exchanger
* Energy counter (input votage, input current, redressor current, power factor, active/reactive energy etc )* Automatic sinterring mode which do not requýre thermocouple unit.* Over 30 messages for warning-failure and information data.* Automatic pumps turn-off mode* Audio visual warning units

GENERAL
R&D Department of EGES Company hasrecently developed ECOMELT series inductionfurnace system which is the output of 30 years of experience gained on Ultramelt system.
EGES has produced this economic inductionfurnaces mainly for the foundries wishing to set aninduction furnace at their premises.
ECOMELT series furnaces are almost containthe same features of ULTRAMELT series furnaces.All controls are done by a”microprocessor unit”thet has been developed by EGES engineersDatailed informationabout printed circuits andalarms are given above

ECOMELT SERIES INDUCTION FURNACES
EGES R&D engineers continuosly follow up to date technologyand electronic components coming up to the market.All newInnovations are examined,tried and if it contributes to EGES qualitywhich is already represents the excellency, are used in EGES products.
Steel Connstruction ECOMELT Furnaces :These type of furnaces give better results under heavy workingcondititions and their sound level are very low.
Special Coil design with Early Warning Detection
Special sensor pins are welded regularly on inner coil side toreduce the hazard of metal penetration which increase the liability of the system
Power unit (converter) produced with high standards electronic components
On ECOMELT series furnaces, all negative and weakpoints of aluminium body furnaces are eliminated.A new So, durable,trouble and free no after sale service requrýed a new furnace is manufactured.
Thanks to ECOMELT series furnace system;With a small investment budget, all foundrymen can able to set an effcient furnace, at theirbest satisfaction.

Converter Unit
Converter Unit With Parallel Resonance SystemIt is obvious that high current in electrical circuits meanshigh percentage of defaults. Current which goes through thyristors at parallel resonance converter are very low incomparison to serial resonance circuits.For the same power,serial resonance current is almost 5 times higher than parallel reonance circuit.
Decreasing Melting Cost by ContinuousFixed Power:Beginning from the first charge EGES ECOMELT furnaces use continuous and fixed power energywhich helps to reduce melting time, causing lessenergy consumption. “Full power “ is adjusted automatically by the unit itself without any interference by the Operator.
Full Power operration under Low Main VoltageMainly in less developed countries where electric distributionconditions are rather poor, EGES ECOMELT Induction furnaces can be operated at full power even -20%, +15% voltage fluctiotions.
High electric Efficiency:ECOMELT furnaces is designed to minimize energy losses. Power factor is better than 95 %
Electronic Earth LeakageIndicator with adjustable sensitivity
EGES ECOMELT furnaces are equipped with adjustable sensitivityEarth Leakage Indicator to control continuosly the leakage level in the system. The leakage indicator at same time, gives the opartoran idea about the thickness and/or the quality of furnace lining Ledbar type earth leakage display indicates to the operator the refractory lining quality as GOOD-FAIR-BAD with GREEN-YELLOW-RED colours.If metal penetrates through the furnace at RED warning colour thefurnace stops automatically toin order avoid further damages.
