Units designed for low outlet temperatures (up to 750°F) and units designed for high outlet temperatures (up to 1100°F). Both these models have general purpose terminal enclosures (NEMA 1) and utilize rugged 0.430in diameter Incoloy tubular heaters that are arranged in an optimum configuration to minimize the pressure drop.
