Lm-therm heaters with a built-in thermostat ensure that the climate is ideally adapted to the operative procedures. The devices ideally use the exhaust heat from the running processes and prevent condensate formation. This has a positive effect on the lifetime of control cabinets and actively lowers the power consumption.
A 2-point bimetallic temperature controller reliably prevents high surface temperatures. Factory settings adapted to all kinds of switch-on and shutdown temperatures are also available.
This is complemented by a high-quality aluminium housing which is constructed according to thermotechnical standards. Both the high-class heater casing and the ceramic heating elements are of very high quality. Furthermore, Lm-therm heaters with a built-in thermostat do not require an additional controller. This saves you money!
The Lm-therm self-regulating PTC heaters consist of a specially designed aluminium body and custom-fit built-in PTC elements. The PTC heaters also stand out due to their high quality. A sophisticated system of aluminium cooling fins supports the technology, which is suitable for a high operating voltage range.
Since a predefined switch-off is not possible for PTC heaters, installing a separate controller is recommended. We are very glad to help you choose the right Lm-therm controller for your needs.
The Lm-therm fan heaters can be equipped to meet the requirements of the respective place of installation perfectly and also lend themselves to modular installation. We offer a selection of fan heaters in different voltage, output and mounting versions.
With up to 8,000 W, Lm-therm fan heaters ensure maximum heat output – even in regions with temperatures as low as -40°C. A built-in temperature limiter prevents dangerous heat build-ups. The devices can withstand high purge temperatures.
The Lm-therm fan heaters meet our high quality requirements. Stable metals like aluminium or stainless steel ensure that the housing units are mechanically robust. The built-in vibration-proof quality fans have a very high durability with their guaranteed operating life of at least 50,000 hrs. The devices are also tested in a shock and vibration test according to the EN 60068-2-6 and EN 60068-2-27 standards.
The Ex safe zones 1/21 and 2/22 assume that specific structural requirements are met. The Lm-therm Elektrotechnik AG Ex heaters with an electric voltage of 115 V and 230 V are suitable for use in explosive areas like petrol stations, biogas plants and chemistry laboratories, etc. The Lm-therm Ex heaters are protection class IP66/67 and meet the requirements of standard 2014/34/EU.
The devices which are equipped with explosion-proof thermostats monitor thermal processes. The Ex heaters work according to the principle of fluid or gas expansion. A pressure-resistant encapsulated microswitch serves as an electrical switch element.
