| IP68-rated convection heater  Intertec announced a compact new convection electric heater that has been designed for temperature maintenance or control in harsh environments such as wells, tunnels, water and wastewater plants, pulp/paper mills, rendering/food processing environments, and any dusty or wet process conditions. The heater has been optimized for reliability, through features including a fully potted and factory-sealed design, and is rated to IP68 — allowing it to function even when fully submerged. Additionally, it has no exposed contacts, so it is highly reliable even in corrosive atmospheres with hydrogen sulphide or ammonia for example. Available with power outputs from 25 to 500 W, the new solution is much smaller and easier to install than the common option of trace heating cabling. The new product is a variant of Intertec's field-proven and explosion-proof Multitherm design for heating in hazardous environments, with the same high-integrity features, but without the protection markings. Multitherm features a compact 8x8 cm square shape designed for vertical mounting, with surface profiling that optimizes convection heat transfer. This form factor typically allows the heating element to be positioned closely alongside any process equipment that requires protection against freezing or condensation, or temperature regulation. The heater body is fabricated from seawater-proof aluminium, with a black anodized finish. write your comments about the article :: © 2008 Construction News :: home page |
