Refiny EMF-i Drive
EMF-i drive heating equipment is a unit that converts electrical energy into heat using electromagnetic EMF. The AC input power (220V/380V/415V/660V, 50/60Hz) is converted into the direct current through the rectifier circuit, and then the direct current is changed to high-frequency alternating current, The frequency ranges between 5-30kHZ. The alternating magnetic field is created when a high-frequency alternating current is delivered to the EMF coil, it penetrates the objects (iron, cobalt, nickel, and other metals having magnetic permeability) to allow generating eddy currents. Heat is produced where these eddy currents flow, that is, inside the object. Through the inducting heating process, metals can be heated rapidly and efficiently.
Power supplies are one of the important components of an EMF heating system. REFINY designs and manufactures EMF heating power supplies with 0.5KW-320KW of output power and a 5-30kHz frequency range, suitable for several EMF heating applications, such as rubber & plastic processing machinery, industrial furnaces, biochemical equipment, food machinery, medical equipment, hot air-drying equipment, hot water equipment, thermal oil equipment, paper making machine, electroplating machine, etc.
Features of EMF Heating
Energy Saving
Using electromagnetic EMF heating, a heating efficiency of over 98% can be achieved, providing energy savings of 30% or more in comparison with conventional electric heating units.
Safe & Comfortable
The surface temperature of the EMF heating coil is approximately 60°C only, which efficiently prevents humans from burn injuries and avoids the risk of high workshop temperatures caused by large amounts of heat that is usually generated from traditional heating resistance surfaces.
Long Service Life
In EMF heaters, the coils are wound up by high-temperature resistant wires that feature a good insulation performance. The coil does not contact the workpieces and can provide a long service life of more than 10 years while reducing maintenance costs.
Even Heating & Accurate Temperature Control
With extremely low thermal inertia, EMF heating can achieve accurate control of temperature and even heating. Therefore, the product quality and productivity can be significantly improved.
Intelligent Control & Low Labor Intensity
The EMF heating unit has functions of automatic control of heating temperature, automatic start / shut down, automatic circulation heating, and pre-setting of temperature and time, attended monitoring is not required.
EMF-i Barrel Heating Solution
EMF-i drive Heating for Plastic Processing Machinery
This solution aims to use EMF heating to replace resistance heating for plastic processing machinery. As a result, the energy efficiency, processing performance, productivity, control precision, and operation stability of plastic machines are all improved.
Features of EMF-i Induction Heating
Energy efficiency 30%-85%
Currently, plastic processing machinery mainly uses resistance heating elements which can produce a large amount of heat radiated to the surroundings. Induction heating is an ideal alternative to solve this issue. The surface temperature of the heating coil ranges between 50ºC and 90ºC, the heat losses are significantly minimized, providing energy savings of 30%-85%. The energy-saving effect is, therefore, more obvious when the EMF heating system is used in high-power heating equipment.
Safe & Comfortable
EMF-i drive heating system enables the surface of the machine to be safe for touching, and that means it can avoid burn injuries which often occur in plastic machines that use resistance heating elements, providing a safe workplace for operators.
Fast heating, high heating efficiency
Compared to resistance heating whose energy conversion efficiency is approximately at 60%, EMF heating is over 98% efficient at converting electricity to heat.
Lower workplace temperature, higher operation comfort
After using the EMF heating system, the temperature of the entire production workshop is lowered by more than 5 degrees.
Long service life
In contrast to resistance heating elements that have long-lasting work at high temperatures, EMF heating works at near-ambient temperatures, therefore efficiently prolonging the service life.
Accurate temperature control, high product qualification rates
The EMF heating provides low or no thermal inertia so that it will not cause the temperature overshoot. And the temperature can remain at a set value of 0.5-degree difference.
EMF-i drive steam generation system
steam is produced within 5 seconds without pre-heating
Compared to traditional resistance heating which takes 5 minutes to produce steam and traditional coal-fired boiler which takes 50 minutes to produce steam, EMF heating offers higher heating efficiency with only 5 seconds, greatly saving energy, time, and cost.
Intelligent control, easy to operate
An intelligent control system, real-time display of steam temperature and pressure, 24-hour segment timer start/shut down, and one-key start are significant features making operators use. Besides, attended monitoring is not required, so that the labor cost is efficiently reduced. The system is certified by Indian standards and Special Furnace Body, and the service life can reach 10-12 years.
Safety and reliability
The steam generator that adopts inducting heating technology has an insulator between the electric wire and the heating unit, so it will not cause electricity leakage. Fault detection and alarm systems provide comprehensive protection in all aspects of water leakage, electricity leakage, high pressure, high temperature, water shortage, etc.
Modular installation
EMF heating steam generators can be installed individually, or multiple units in parallel to be used per actual application needs, thus providing easy installation and space saving while reducing installation expenses and piping costs.
No need for annual boiler inspection, and the highest steam temperature of 500ºC
The volume of the heating unit is less than 20L, eliminating the need for annual boiler inspection. The pressure and temperature of the steam generator can be easily adjusted, allowing 500ºC high-temperature steam to be produced under shallow pressure.
Energy efficiency 30%-60%
EMF heating is over 98% efficient at converting electricity to heat, it saves more than 30% energy in comparison with traditional resistance heating methods. The EMF heating steam generator is 10-50 times faster than traditional boilers in steam production, it currently is an energy-efficient steam generator in the market.
Eco-friendly, clean workplace
With no need for an open flame, EMF heating does not produce dust, odor, noise, or hazardous gases, complies with the National Energy Conservation Policy requirements, and provides a safer and cleaner workplace for operators.
Combining techniques of water cooling and waste heat recovery
With exclusive patent technology, the system features high waste heat utilization and efficient energy saving.
