Modine PTN500 Vertical Hydronic Unit Heater Features:
• Heavy Duty Cupro-Nickel Tubes are available for High Pressure / Temperatue Aplications, up to 250PSI or 400F.
• These units are compact and light-weight, requiring fewer man hours to install.
• Integral junction box for ease of electrical wiring.
• Exposed coil for easy cleaning.
• All models through PT/PTN-279 have hanger brackets with 5/8" diameter hanger holes for 3-point suspension.
• All models larger than PT/PTN-279 have hanger brackets with 5/8" diameter hanger holes for 2-point suspension and angle supports for 4-point suspension.
• Motor-Cooling Cone - Shields motor from soil heat - prolongs life of insulation, windings, and lubricant. Prolongs motor life.
• Ideally suited for applications where steam pressures exceed 30 PSI and critical mounting height restrictions exist.
• Due to special coil design, the discharge air temperature of LOT models is approximately the same as the standard unit operating on lower steam pressures.
• Air distribution is increased through higher air volume/velocity.
• Ideal for use in dirty atmospheres because greater fin spacing increases resistance to foreign particle build-up.
• Coil - Aluminum fins firmly bonded to tubes for maximum heat transfer. Steam and water-carrying passages between extra-heavy steel pipe connections are copper for model PT and cupro-nickel for model PTN.
• Motor - All motors are totally enclosed. Single phase and explosion-proof types include built in thermal operation on specific unit heater models.
• Fan - Accurately balanced to operate quietly and at lowest possible power cost.
• Junction Box - All motor wiring is terminated in a electrical junction box either supplied on the unit heater casing or as an integral part of the motor.
• Horizontal Fins - Exposed for easy cleaning with air hose and brush.
• Casings - Baked-on, gray-green high solids paint applied over rust - and corrosion - resistance treated steel lasts longer.
