ENEA plus is the most used heat exchanger in the ceramic industry for the cooling of oil in the presses. Thirty years of experience for a totally renewed project with record-breaking performances. Studied for every press model and to work in the harsh environments typical of the ceramic industry. Easy to be installed, totally maintenance free, sharp looking to energy saving and respectful of environment sound level. VERSATILE Worldwide, from the smallest to the largest gear press: the choice is always ENEAplus UNIVERSAL From warm areas to cold ones all over the planet: ENEAplus speaks all languages in the world. ECOLOGICAL Water is a limited necessity: ENEAplus does not use it! SILENT Noise pollution is a health hazard: ENEAplus works on tiptoe, guaranteeing a sound pressure level lower than 72 Db (a) ECONOMIC Electricity is an important part of the budget: ENEAplus saves a lot of it! SIMPLE The off-line circuit receives hot oil and return it to the machine cleaned at the desired temperature. CLEAN It can be equipped with an optional element which is able to reverse the air flow of electric fans for a total cleaning of the radiators.

High efficiency, anti-oxidation aluminum alloy radiators, totally designed and manufactured in Italy to enhance ENEAplus performances.

Silent, automatic start, energy saving and high hydraulic head aspirating electric fans.

Automatic shut-off valve for low temperature, completely automatic and controlled by electronic panel, thermocouple detecting oil temperature.

ENEAplus is simple and fully automatic

Screw pump with three special steel rotors and Viton seals. Two speed motor for a great energy saving.

1. At the start the pump is positioned at a low speed. The oil is automatically bypassed and it is not lead into radiators until it reaches 37C°. 2. At this threshold, the oil is circulates inside the radiators. The pump is at a low speed and electric fans are off.

Electric control panel, directly installed on the machine border.

3. When the oil fixes a temperature of 39C°, the first electrofan turns automatically on. (or the first couple of electrofans in double Eneasplus) 4. When the oil fixes a temperature of 41C°, the second electrofan turns automatically on. (or the second couple of electrofans in double Eneasplus)

Mechanical safety check valve and safety pressure switch

5. When the oil fixes a temperature of 43C°, the third electrofan turns automatically on. (or the thirdc coupe of electrofans in double Eneasplus) 6. When fixing 44C° the first pump turns at high speed (speed 2). In case of double pump, the second one turns at high speed at 46C°, in order to give the highest performance and to guarantee a perfect cooling even with bad environment conditions as well. PLC for oil temperature setting and data monitoring.

Particular manifold HPPC In the versions with double radiator, connection manifolds with elastic joints.

IMPORTANT: The pipe diameter depends on the total length (supply and return). Maximum difference in height between the press tank and ENEAplus must be 20 meters. The pressurization of the tank must not be less than 1.8 bar. Use only WIDE RANGE curves and calculate 10 meters for each curve. The machine must be connected to the supply and return rigid oil pipes, connecting two flexible rubber pipes of at least 1000 mm in length, to prevent the transmission of vibrations.
