The new NTC Temperature Control Unit is available from AB Systems
A new range of water and oil temperature control units can achieve economical and precise results, according to a UK process cooling specialist.
Buckinghamshire-based AB Systems is distributing the new NTC units from Italian cooling OEM, Nova Frigo, to the UK market and says the low-noise range is designed to fulfill accurate heating and temperature control of injection moulds and extrusion barrels/cylinders.
To deliver accurate temperature control to plastic/rubber injection mould tools and dies – and thus ensure high levels of plant productivity and system efficiency – the NTC range is said to be intelligently designed to allow the set temperature to quickly and accurately return to the set point value, minimising temperature fluctuation.
This, says AB Systems, is largely thanks to PID logic, which allows continual auto-tuning adjustment and accurate regulation of process temperature. This controlled action adjusts the power supply automatically and adapts it according to the external load conditions, resulting in “considerable” energy savings.
To further reduce energy consumption, the units feature a wide exchange surface of the modulating valves and exchangers, which when combined, allow the temperature to reach the set point value extremely quickly and accurately.
In addition to microprocessor temperature control, the NTC units feature digital temperature display, automatic water filling, and allow direct and indirect cooling. Each unit also comes with a range of over temperature alarm and external thermocouple options.
Water versions of the NTC, available in models from 3-24kW, offer direct cooling up to a maximum of 90°C, and indirect cooling allowing continuous operation between 90-160°C. The units can be used in conjunction with a chiller to achieve a closed cooling circuit with zero water consumption, offering maximum energy efficiency and productivity. Oil models of the NTC are available with capacities from 3-36kW, and offer indirect cooling between 150-250°C.
In total, the range comprises 28 water or oil models with capacities ranging from 3 to 36kW. Leak stopper models are also available.
