Description: Product SummaryCaloritech Type "PH" Electric Control Panel Enclosure Heaters are fan-forced air heaters designed to control the environment within enclosures by maintaining a stable temperature. Effects of low temperatures such as corrosion, freezing or condensation will adversely affect the components inside control panels. The Caloritech PH enclosure heater provides an optimal performance environment for the critical components contained within the control panel.Features + BenefitsFan AUTO/ON switch to prolong motor lifeExternally adjustable thermostat 0°F to 100°F (-18°C to 38°C)Pilot light for ‘HEAT ON’ indicationTerminal strip provides quick installation with both stranded and solid wireHigh temperature safety protectionOptional DIN rail mountingCSA C/US approvedLight WeightLow MaintenanceAluminum alloy outer casing protects interior componentsScrew fasteners provide easy access to components inside casingHeater Selection The wattage requirement is determined from a consideration of the surface area, insulation properties of the enclosure or space and the temperature difference between the ambient and the enclosure. For small enclosures (less than 100 ft2 surface area) conservative values for heat losses are as shown in Table 1. Example: To find wattage requirements in an uninsulated enclosure 2’ x 3’ x1’, which must be held at 40˚F in a 10˚F outdoor ambient, with internal electrical components that generate 80 watts. Surface Area = 2[(2’ x 3’) + (2’ x 1’) + (3’ x 1’)] = 22 ft2 From Table 1, an uninsulated outdoor enclosure requires 7 watts per square foot for each 10˚F temperature difference. Temperature Difference = 40˚F - 10˚F = 30˚F Wattage Required = (30˚F ÷ 10˚F) x 7 W/ft2 x 22 ft2 = 462 watts Heater Wattage = Wattage required - component wattage = 462 - 80 = 382 watts Use one PH400 rated at 400 watts. For enclosures requiring more than 800 watts, two or more PH heaters may be usedInstallation - The Caloritech PH enclosure heater should be installed in the center of the cabinet and as low as practical for the best possible heat distribution. The optimum efficiency is obtained when the unit is mounted in a vertical position allowing the top air vents to release the heated air in the most effective manner. The enclosures should be sealed and free from dust and dirt. Do not install the heaters on wood, cardboard or other flammable panels. Heat sensitive components should not be placed near the heat discharge area. For larger enclosures, two or more heaters may be used.
