- Page 1 Max Air Heater FOR SAFETY AND LONG HEATER LIFE, CAREFULLY READ THIS MANUAL BEFORE USE.
- Page 2 THANK YOU FOR CHOOSING THE MAX AIR HEATER TUTCO MAX AIR HEATER The Max provides a compact, efficient heater for heating air or inert gases up to 1400°F/760°C. The Max comes in various power ratings ranging from 6kW to 36kW. Two (2) type “K” thermo- couples with a convenient terminal block are included for ease of wiring.
- Page 3 WARNINGS! TUTCO SureHeat Process Air Heaters contain high watt-density elements and must be controlled carefully to prevent element failure. IMPORTANT: Be sure to read and understand this operating manual before turning the system ON. Follow all checklists shown in the manual. Failure to do so can cause a heat- er failure and may void warranty.

- Page 6 DIMENSIONS/MOUNTING NOTE: The inlet side of the heater is located where the leads/power feedthrus come out of the housing. Failure to install NOTE: The inlet side of the heater is located where the leads/power feedthrus come out of the housing. Failure to install the heater in its proper orientation can result in heater damage and is not covered under the manufacturer’s warranty.

Page 11: Performance Curves
PERFORMANCE CURVES The attached performance curves show exit air temperatures at different airflows and voltages. Pressure readings (longer dashed lines) are measured at the inlet to the heater with no entrance or exit restrictions. MAX MAXIMUM PERFORMANCE CURVE Temperature measured by the internal S2 “K” thermocouple Minimum recommended airflow is 12 SCFM (340 SLPM) - Page 12 Solid lines indicate safe, normal-life operating conditions. The shorter dash lines indicate marginal, shorter-life operating conditions leading to premature burnout. With a known flow (or pressure) at the heater entrance, follow the flow (or pres- sure) line across until it meets the desired temperature curve. Drop a line straight down to intersect the x-axis. This point, along the “Heater volts –...
