Three-phase and neutral line filters are a compact solution for the interference suppression on the mains input of cabinets and control units of equipment, ranging from industrial applications like machine tools to sensitive medical installations. These typically involve separate and often
insufficiently filtered frequency inverters and SMPS, causing current imbalance and significant interference problems. As individual elements they may be interference-suppressed already. The conjunction of several switching components in the same cabinet and a non-EMC conscious cabling will rise the demand for an additional EMC filter on the mains input of the whole installation. Many times this is the only way to get the CE mark for the cabinet in accordance with the EMC directive.

The conventional output-choke has a very good storage capacity. It functions like a typical series inductance and smoothes the symmetrical, effective current and the asymmetrical, parasitic current. The voltage rise is limited to less than 500 V/µs. The line to line voltage peaks at the motor terminals are lower than 1000 V. This solution attenuates the cable-conducted disturbance really well, even in the lower frequency range. The electromagnetic radiation from cables is attenuated considerably. Losses and typical motor noise, caused by harmonics, are reduced.

ENCAPSULATED COILS
These coils have a natural application in the field of solenoid valves for the most varied sectors.
The range is composed of numerous types, with different dimensions, powers, materials and electrical connections. The standard versions and the availability of developing new ones, allow optimum solutions for even the most complicated demands.
LINEAR SOLENOIDS
These solenoids are used in the most varied industrial applications where there are demands for linear actuations.
They are available with galvanised steel body or with encapsulated coils, allow an high number of hourly operations and guarantee an extremely long life cycle.
HOLDING SOLENOIDS
The holding solenoids, designed to operate in DC, are characterised by a rugged body in galvanised steel.
The range allows for external diameters from 19mm to 70mm. Holding force goes up to 1.300N. This feature is even more relevant considering the possibility of continually operating at ED100%.
LOCKING SOLENOIDS
DELTA production is aimed at constructive choices for both simplicity and robustness, guaranteeing maximum reliability and efficiency. They are available in three different sizes, all have a built-in return spring and are produced with encapsulated coils or with stainless steel body.

hotset presents a wide product spectrum of hotspring® coil heaters:
- Starting with WRP / Micro up to WRP / Maxi with different lenghts and diameters.
- Brass-coil heaters or coil heaters with clamping mechanism as heating elements for different applications.
- Heating systems such as the hotcast® sealed heater (GMH) or the hotcone® heated nozzle (BMD).
- Special products such as hotslot® and hotslight®.
- As well as a wide spectrum of applications.
hotset was already in 1980 one idea ahead as they presented the first round coil heater (type WRP Ø 3.3). Since then further innovations have been made: WRP / Mini, flat and square coil heater (WRP / F resp. WRP / Q), WRP / Maxi as well as WRP / Micro.
This innovation as well as the humidity-resistant coil heaters according to I.P. 65 (WRP Ø 3.3 - WRP / F 2.2 x 4.2 – WRP / Q 3.0 x 3.0) emphasize the consequente alignment to new challenges.

LONGITUDINAL ELECTRO LIFTING MAGNETS
These magnets are used to lift bundles of material with an irregular surface, which complicates lifting operations. Longitudinal magnets, however, have a particularly deep penetration field that makes them unsusceptible to such irregularities. This enable safe and effortless transport of bundles of material. Moreover, two or more of these magnets can be used, depending on the length of the bundles. In the event that people are present in the lifting area, however, extra mechanical slings must be fitted for safety purposes.

Electropermanent magnets utilize permanent magnetic material surrounded by an electrically powered coil. To energize an electropermanent magnet, a momentary pulse of D. C. power is applied to the magnet's coil in order to charge the permanent magnetic material within. Once energized, the electropermanent magnet does not require a constant source of power to retain the lifted steel coil. To release the steel coil, a reverse pulse of D. C. power is applied to the magnet's coil. The Electropermanent magnet design tends to excel when the steel coil's edge stagger is kept to a minimum.
Special Adaptations (Standard Circular, Rectangular, and Bi-Polar)
Able to prevent "telescoping"
Less storage space required
Transport requires less manpower
