Description

Application – Caloritech PXFT heaters are designed to maintain a stable temperature inside control enclosures, pump houses or similar spaces. The standard units are not suitable for use outdoors, unprotected from the weather. All heaters have a built-in thermostat. The heater is also available without a thermostat on special order. Features – The PXFT heater uses a high surface area aluminum heat emitter to eliminate the need for a fan while providing low radiation and high convection heating to the enclosure. The thermostat rating is 25 A at 240V, Single Pole, Single Throw, adjustable from 30°F to 120°F (0°C to 50°C). A movable bracket allows the heater to be floor or wall mounted with the terminal box located on the left or right side, top or bottom. Wire guards are provided standard with the PXFT-300, PXFT-400 and PXFT-600-watt heaters, and are available as an option on the PXFT-050, PXFT-125, and PXFT-200-watt units. Moisture-resistant heaters (shown below) are available on special order. 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 100ft.2 (9.3 m2) surface area) conservative values for heat losses are as shown in Table 4 page C6. Installation – Caloritech PXFT heater is approved for horizontal or vertical mounting on the floor or lower wall of the enclosure. Heaters must be installed using the mounting bracket provided to ensure minimum spacing between the heater and the wall or floor. Try to maximize the spacing between the heater and temperature sensitive components. Surface temperatures of the 50 -watt and 125-watt units are about 212°F (100°C) and 338°F (170°C) respectively. The other units listed operate around 410°F (210°C). Panel Enclosure Heaters ? Types PH and PXFT Designed to prevent condensation and freezing in control panels, eliminating costly damage and down time. PH heater is available in four wattages ranging from 125 to 800W and utilizes a fan to circulate air in the panel, reducing temperature stratification. PXFT heater is a natural convection heater, available in wattages from 50 to 600W. Both types have built in thermostat control. Caloritech?
