Despatch Announces Uniformity Test Results for LAC2-18 Bench-top Oven Used to Cure Adhesives

Minneapolis, Minn., U.S.A. January 13, 2015 –Despatch ovens are known for superior temperature uniformity which is critical to consistent product quality. Uniformity is confirmed using a nine-point test conducted in an empty oven after stabilization period. A second test with product loaded should also be conducted to ensure that the oven is delivering uniform heat to all parts.

A customer wanted to use the Despatch LAC2-18 bench-top oven for curing an adhesive used to mount a high-mass (8-pound) structure to a thick-gauge aluminum plate. Temperature uniformity needed to be confirmed before a decision could be made since just a slight variance will damage the parts.

“The customer supplied Despatch with parts which were loaded onto three shelves in the oven,” said Daniel Ruf, Despatch Engineering Manager. “Each part was fitted with a calibrated thermocouple in order to measure the product temperature. Three additional thermocouples were used to measure the air temperature on each level. The temperature range of all six thermocouples was within +/- 0.7°C. This result is considerably better than the published +/- 1.0°C specification of the oven.”


The test results on a loaded LAC2-18 oven shows all six thermocouples are within +/- 0.7°C.

 

The LAC2-18 bench-top oven features horizontal recirculating airflow and exceptional temperature uniformity. The high-performance oven delivers temperatures up to 260ºC (500ºF). A high-volume fan circulates air through perforated, stainless steel walls to create a constant horizontal airflow across all sections of the oven. ¬The result is proven reliability in demanding production and laboratory applications such as curing, drying, sterilizing, aging and other process-critical procedures.
