Simpson Multi-Cooler Sand Cooler
As foundry sand preparation and molding plants become increasingly high-speed and quality-oriented, the control of return sand temperature is essential. The Simpson Multi-Cooler is specifically designed to provide the mixer group with sand that is cooled to temperatures that allow optimal mulling, premixed to eliminate return sand variations and with a moisture content controlled within tight tolerances. The result is optimal mulling and high-quality, profitable castings.
Continuous sand cooler and pre-conditioning system operating on the principle of evaporative cooling.
Sand systems with return sand temperature above 49°C and/or wide variations in return sand properties.
- Pre-mixing with back-blending and controlled retention
- High-efficiency cooling to below 49°C or 10°C over ambient
- Discharge moisture of 2.0% +/-0.2%
