Moretto: New temperature controllers first at FAKUMA

MORETTO S.p.A. (www.moretto.com), based at Massanzago in Italy, one of the world’s leading manufacturers of automation equipment for the processing of plastics, has exhaustively looked at the subject of mould cavity temperature control, undertaken research and finally presented the gathered requirements to its in-house research and development department. The aim was to introduce a complete market-ready family of temperature controllers at FAKUMA for the first time worldwide, named TE-KO, comprising two stand-alone product ranges, one based on water, one on oil, each with eight models, satisfying present and future market requirements. Those requirements are solved as follows, taking into specific consideration fast and impeccable commissioning:

• Working controls: the device controls volume and checks operating pressure, ensuring that the coolant volume is actually circulating.

• Heating: the resistors located in two different areas increase the relevant performance

• Cooling: a tubular stainless steel heat exchanger with double winding generates 50 kW refrigerating capacity. Heat accumulation is impossible.

• Electrical connections: TE-KO comes with power supply cable. RS485 serial port.

• Hydraulic connections: TE-KO has 4 input and 4 output connections as standard, in order to solve the issue of branchings, connections and manifolds once and for all.

• Filter: available with high capacity, accessible from the outside, due to fast lock feature (optional). The cooling liquid contains glycol or anti-freeze agents. The large filter absorbs sediment over long periods of time, thus maintaining optimum long-term heat exchange capability.

• Volume: the 16 liter capacity of the super tank is double that of conventional systems. The oval shape of the trough ensures ideal mixing of the coolant; the stainless steel construction guarantees a long service life.

These are the principal characteristics of the new TE-KO temperature controller, entirely constructed of AISI 304 stainless steel, thus perfectly resistant to water-induced corrosion. In addition, TE-KO is equipped with a display feature, enabling the user to access a variety of real-time data. The device is equipped with PID-control technology via a micro processor, managing all relevant functions. Temperature control is based on values transmitted by solid-state relays. Moreover, Moretto uses the most reliable pumps on the market for guaranteeing duration in time.

Great emphasis has been placed on accessibility, so that all essential tasks required for problem-free operation of the equipment are easy to perform. A version designed to operate under vacuum – to prevent possible loss of liquid – completes this range of products which are designed specifically for a long operation lifespan.
