The LHS 210 / 410 Air Heater Series – Compact and powerful

Leister’s new series of compact and powerful LHS 210 / 410 air heaters are suitable for installation in industrial plants where space is limited or tubular air systems such as furnaces for heat curing processes, due to their compact design and ease of integration.

With a choice of eight air heaters with single (SF) or dual flanges (DF), the innovative design allows for easy electrical connection, with connection housing separated from the airstream, which allows unhindered air flows through the air heater with minimal loss in pressure. The connection housing is also protected against overheating, making it possible to work with an air inlet temperature up to 350 degrees Celsius.

The SF-R and DF-R air heaters are equipped with an extension on the housing connection. The ceramic inside this extension ensures that the electrical connection on the tubular air heaters is sealed off and protected from high temperatures or backflowing hot air.

The series SF-R and DF-R (“recirculation”) are designed for many industrial processes where hot air recycling is required. The recirculation abilities of these models lower energy consumption which reduces CO2 emissions and saves money.

One of the distinguishing features of the SF and SF-R models is that they are compatible with Leister’s extensive line of nozzles and are suitable for countless industrial applications. For example, the air flow can be extended with a wide slot nozzle or distributed over a larger area. Various shrinking applications within the packaging industry are possible with a screen reflector nozzle.

Whilst the Leister LHS 210 series produce an air volume of 80-250 l/min, the 410 range generates a larger air volume of 160-420 l/min, with all air heaters supplying hot air up to a maximum 650 degrees Celsius.

The LHS 210 / 410 Series – Compact, powerful, and reliable air heaters for space limited industrial processes.
