Extreme-duty model extends this family of blower heaters
Chromalox
The CXH-XD blower heater (photo) is designed to withstand corrosive and wet environments and is ATEX-certified. It extends the capabilities of the company’s CXH-A units, by providing either primary or supplementary heating (for comfort or freeze protection) in areas that are classified as hazardous locations. CXH-XD enhancements include a corrosion-resistant, coated heat exchanger, optional 316 stainless- steel and epoxy-coated frames, as well as a corrosion-resistant and washdown-rated fan motor. With these added capabilities, this unit is suitable for use in onshore and offshore drilling platforms, pump houses, power-generating stations, water and wastewater plants, chemical storage facilities, pipeline-metering stations and more, says the company. The use of heavy-duty magnetic contactors and a low-voltage transformer simplifies installation. The CXH-XD model comes with power ratings from 3 to 35 kW, which provides heat outputs to 119,420 Btu/h. It is offered for three-phase voltages starting at 240 V, while an optional 690-V design is also available. — Chromalox, Pittsburgh, Pa.
