Inline air heaters such as the LHS 61S PREMIUM are used for rapid air heating and specific hot air applications in industrial processes. Through the 62 mm (2.4 in) wide heating tube, the device distributes hot air efficiently and is individually adjustable for respective requirements through various accessories and nozzles. Integrated power control allows easier installation, because fewer cables have to be laid. Not only does this reduce installation costs, but also reduces the risk of faulty connections.
The electronic control on the LHS 61S PREMIUM is continuously variable via a rotary potentiometer on the upper housing part. This ensures an extremely precise power control. Because the control is done electronically, it works quietly and without practically any wear. All LHS PREMIUM models from LEISTER are supplied with an integrated relay with an alarm contact, which shows any failure and triggers overheating protection if necessary.
