STEGO, a specialist in thermal management, has introduced enclosure heaters featuring a new loop-style heating element. These heaters are available in five different series, with power outputs ranging from 10 to 150 W, to meet various thermal management requirements. The heaters are certified safe for use in applications exposed to shocks and vibrations, making them suitable for a wider range of applications. Furthermore, pressure clamps are used to reduce installation time.
Enclosure heaters are the tool of choice for preventing condensation in control cabinets. Heating the air inside the cabinet avoids temperature fluctuations and keeps relative humidity constant, thus protecting electric and electronic components against harmful humidity as it condenses and preventing short circuits. STEGO, a pioneer in enclosure heaters, will be showcasing its enclosure heater with a completely new heating body: the loop heater. No fewer than five series featuring the new body are being launched on the market: the LPS 164 and LTS 064 series are based on the compact loop profile and deliver a heating power of between 10 and 50 W, while the larger loop profile in the LT 065, LTF 065 and LP 165 series gives them a heating capacity of 50 to 150 W.
The most striking product and design feature of the compact convection heaters is the innovative aluminium profile strip that forms part of its heating body and, in fact, gives it its name – the loop – based on its shape with similarities to a figure-of-eight and thus also the symbol for infinity. This profile is extremely efficient at absorbing the heat from the PTC heating elements, meaning that users benefit from improved, uniform heat transmission inside their control cabinet.
All loop heaters come with a clip so that they can be attached quickly to their 35 mm DIN rail. Pressure clamp connection reduce installation time for the user by up to 50%. Cables with rigid wire and ferrules can be connected quickly and without any tools. The clamps exert constant pressure on the cables, which provides added security when transporting pre-assembled control cabinets, for example. You therefore need not worry about the connecting cables ever coming loose during operation. The LTF 065 loop heater series with integrated tamper-proof thermostat offers additional potential for savings as there is no need to have a separate thermostat for control purposes. The LTS 064, LT 065 and LTF 065 series are designed to be touch-safe. Their light-grey, insulated plastic housings keep the surface temperature under 80°C, thus protecting maintenance and operating personnel from burns in the event of accidental contact. STEGO products are approved and safety certified independently by globally recognised testing institutes such as VDE, UL and EAC.
The loop heaters are shock- and vibration-proof and have the approvals to prove it. The innovative loop profile allows the heater to be assembled in a completely new way: rather than being pressed together, the heating body and heating element are firmly interlocked by the spring action exerted by the loop profile.
