Material Drums and Transfer Pumps

The source of all spray foam work begins in the materialdrum and transfer pumps. Here's how to maintain these components.

  • Material Drum: Your materials should be kept securely in tanks under the recommended conditions. It may be necessary to use a Powerblanket Drum Heater to keep the materials insulated during the winter. Trap moisture before it causes crystallization with a desiccant filter.
