Working with a major paint manufacturer we were asked to develop two environmental test cells; creating specific atmospheres designed to simulate areas and conditions of the world for paint to be applied. New products required set parameters for paint to be applied specifically for defense and scientific research so testing was imperative.
We met very exacting requirements for two bespoke test cells.
- One to be fixed at 25C with 50% relative humidity and approximately 10% fresh air
- The other with variable set points – from 5C and 10% relative humidity to 40C and 80% relative humidity and anywhere in between.
We designed and installed a system which included an air handling unit, cooling coil, heating coil and humidifier to achieve the requirements of the fixed booth.
In the variable booth test cell, fresh air enters through filters in the ceiling and extracts through the floor. The operating software had to perform at infinite set points and the equipment’s range had to be able to cope with both ends of the scale, leading to a significant air handling challenge. Our installation of a desiccant wheel to dry the air stream provided the low relative humidity and temperature conditions required.
