Thermal management specialist STEGO presents its enclosure heaters with an innovative, loop-style heating body. The company is offering a total of five heater series ranging in power from 10 to 150 W for thermal management applications. Certified safety when exposed to shocks and vibrations enables the heaters to be used for a wider range of applications, while pressure clamps help to reduce installation time.
Loop heaters to prevent condensation inside your control cabinet
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 loop: a brand-new design for the heating body
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.
Safe and user-friendly
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.
Shock- and vibration-proof
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. The elastic property of the aluminium profile is leveraged to maintain a strong force on the heating elements at all times, even in the event of temperature cycles during operation, and to ensure constant heating power throughout the heater’s service life. The effort that went into this design has been well worth it: all touch-safe loop heaters, i.e. the LT 065, LTF 065 and LTS 064 series, have been successfully tested for shock and vibration resistance in accordance with the standards DIN EN 60068-2-27:2010-02 and DIN EN 60068-2-64:2009-04 in relation to the standard DIN EN IEC 61373:2011-04, cat. 1 B. This also makes them demonstrably suitable for situations exposed to a strong vibration impact in environments such as rail and mobile applications or wind power.
