Tangram Technology assesses IR savings

Apr 29 2015 share:

An independent study commissioned by Ceramicx and conducted by Robin Kent of engineering consultancy Tangram Technology has recently measured the detailed differences between a thermoforming customer’s IR heating system when compared to a conventional heating system on an identical thermoforming machine.

Direct comparisons between two thermoforming lines were undertaken using identical tools, products and cycle times. The measuring equipment used for all electrical testing was the Elcomponent SPC Pro.

This is a device that measures all voltage and current of all three-phases of the complete incoming supply to the thermoforming machine utilising one single phase as a reference voltage for the calculations.

The Ceramicx-based heating systems showed a decrease in the average power drawn from 56.16 kW to 32.85 kW, representing a 41.6% reduction. Figures were also taken that showed a direct comparison between the two oven systems. With the machine base loads removed, the Ceramicx system then showed a measured energy saving of 45.8%. Additional study work undertaken showed that yet further improvements and energy savings would be available using the new Ceramicx-based system.

Both machines were directly comparable and both are part of two in-line and fast cycling systems at the customer, loaded with the same tools and both making the same polystyrene-based products for the fast moving consumer goods and food service markets.

The Ceramicx IR-based oven platen and control system was designed and built at the company’s manufacturing facility in West Cork, Ireland, before being shipped directly to the customer’s manufacturing facility. The Ceramicx oven has a total of eight temperature sensors built into the system. These can be selected individually or grouped for control purposes. Additionally the heaters can be subdivided into as many as 132 separate zones, thus giving a wide range of control options.

The Ceramicx oven system features upper and lower heating platens together with power control systems, enclosures, switchgear, and PLC control.
