Thermal Product Solutions (TPS), a global manufacturer of thermal-processing equipment, announced the shipment of a Blue M Clean Room Convection Oven to a specialty technology company. This utility oven will be used to bake parts at 180°C.
The temperature range of this Blue M convection oven is 15°C above ambient to 250°C and has work chamber dimensions of 25” W X 25” D x 28” H. All seams and entrance ports are welded gas tight to minimize leakage. A high rate HEPA filter in the re-circulation air stream provides filtration to an efficiency of 99.99% on 0.3-micron particles. A Yokogawa UP55A programmable temperature controller is employed to control the unit. Based on a nine-point thermocouple survey before shipment in an empty, stabilized oven, the temperature uniformity is ±1% of 180°C.
A Termikfil high temp HEPA filter in the re-circulation air stream provides air filtration to an efficiency of 99.99% on 0.3-micron particles. This also allows operations of up to 250°C. Ramp rates up to 5°C/minute are possible with this filter, but to maintain better particle counts, ramp rates should be limited to <3°C per minute. A Yokogawa UP55A programmable controller employs an easy-to-read, 14 segment large color LCD display.
“Based on the customer’s clean room specifications, we designed this unit with a HEPA filter to deliver clean air to their work zone and packaged it according to clean room packaging standards to reduce the level of contamination during installation.”- Jason Cillo, International Sales Manager.
