The MTF-E series has been designed for use in industrial processes in environments with a potentially explosive atmosphere, caused by gas and dusts, in compliance with ATEX Directive (94/9/EC). In particular, the MTF-E series can be used in areas 1 and 2 (gas) and areas 21 and 22 (dusts) according to the layout and following features:
Three-phase voltage from 220V to 690V, 50Hz or 60Hz; suitable for use with a PWM inverter from 20Hz to the base frequency with constant torque load profile.
2 and 4 poles.
Low Voltage 2006/95/EC, ATEX 94/9/EC.
IEC/EN 60079-0, IEC/EN 60079-7, IEC/EN 61241-0, IEC/EN 61241-1, EN 60034-1.
The components that affect protection are 100% accurately controlled and recorded.
Continual service (S1) at maximum declared centrifugal force and electric power.
Range extended up to 2615 Kgf. (25.7 KN), with centrifugal force adjustable from 0 to 100%.
IP 66 according to IEC 529, EN 60529; mechanical protection is ensured in the mounting phase of the vibrator onto the vibrating machine, by introducing the special seal into the seat on the coupling flange.
IK 08 according to IEC 68, EN 50102.
Class F (155°C).
Standard on all vibrators, with vacuum encapsulation up to size 30, with “drop by drop” trickle system for larger sizes.
From -10°C to +40°C, on request it is possible to have vibrators for max. ambient temperatures of +55°C. On request special greases for temperatures less than –10°C.
On demand with PTC rated thermistor heat detectors 130°C (DIN 44081-44082). Also on request thermistors with different temperatures and anti-condensation heaters.
In all positions and therefore without restriction.
All vibrators are lubricated in the factory and do not require further lubrication if used in normal operating conditions. In heavy duty operating conditions periodical re-lubrication may be applied to frame sizes 40-50-70.
The size guarantees passage of tools used for fixing the vibrator to the vibrating machine. The electrical connection must be carried out using the relative connectors inserted inside the connection box. Special shaped terminals allow to fix the power supply cable, protecting it from loosening.
Three-phase asynchronous type. Designed for maximum starting torques and torque curves adapt for the specific requirements of vibrating machines. Insulated windings using vacuum encapsulating up to size 30; using the “drop by drop” trickle system with class H resin for sizes 40-50-70. The rotor is die cast aluminium.
In high-tensile aluminium alloy up to size 50, in spheroidal cast iron for size 70. An external earthing screw is located on the casing as prescribed by Regulation IEC/EN 60079-0
Constructed in cast iron (ductile or grey) or in aluminium with steel bearing seat. The geometry of the flange transmits the load to the casing uniformly.
The lower and upper bearings have been studied to support the relative load and therefore they have a particular geometry, especially designed and made for this vibrator.
In treated steel alloy (Isothermic hardening) resistant to stress.
Allow greater adjustment of the centrifugal force, with phase shift of the lower weight assembly with respect to the upper group. This adjustment is eased by a graduated scale, which expresses the centrifugal force as a percentage of the maximum centrifugal force.
In aluminium alloy, mounted only on the lower side. The flange side does not have weight cover. Size 40 is supplied without weights covers on both sides.
Electrostatic surface treatment based on polymerised epoxy polyester powder in oven at 200°C. Tested in salt spray for 500 hours.
On request, corrosion high grade protection (stainless steel micro suspensions in a polyurethanic paint) is available.
