Filter fans avoid unwanted heat pockets and protect the electronics. Filter fans from Lm-therm are a cost-effective and simple solution for cooling control cabinets. Not only the slide-on filter fan cover, which allows tool-free filter mat replacement, speaks for the use of Lm-therm filter fans, but also the simple and quick installation without screws make Lm-therm filter fans the perfect solution.

Lm-therm offers filter fans in a wide range of sizes. The filter fans can also be used outdoors with appropriate protection, e.g. with our jet water hood.

In addition to filter fans and control cabinet heaters, we offer an extensive range of thermostats and hygrostats. They ensure an optimal climate in the control cabinet. Our temperature controllers are available either as normally closed/NC for controlling heaters or for switching alarms when the temperature falls below the permissible value, whereby the contact opens when the temperature rises, or as normally open/NO for controlling filter fans, heat exchangers, Peltier cooling units and for switching alarms when the permissible internal temperature of the control cabinet is exceeded. In parallel, we also offer other products such as Ex-controllers, IP-protected controllers and special Peltier controllers.

Our Lm-therm LED lights have been specially developed for use in control cabinets. Two connections - Wieland plug or Pushfit - allow individual connection of the control cabinet lights. Integrated magnets and enclosed clips allow an easy and quick mounting.

The following LED lights are available:

• with 400 Lm or 700 Lm
• wide voltage range (24 - 265V AC/DC) at 400 Lm
• with motion detector or ON/OFF switch
• up to 16 luminaires with AC and up to 8 luminaires with DC voltage can be interconnected by means of a connecting cable

Keyboards and monitors for data centers and industry

Our peripheral devices are specially designed for use under special conditions and offer maximum functional reliability and flexibility. They are the ideal solution for industrial applications, data centers, and server rooms where reliability, durability, and easy integration are paramount—even in confined spaces, high ambient temperatures, or in dirty and vibration-intensive environments.

Your advantages at a glance

• Robust construction: Our devices are designed for continuous operation in industrial and IT environments and impress with their durable mechanics.
• Flexible application options: Thanks to their compact design and variable mounting options, our peripheral devices can be used almost anywhere – even where space is limited.
• High protection class: With protection classes up to IP68 in some cases, our products are suitable for both indoor and outdoor use.
• Versatile designs: Whether as keyboard consoles, monitors, or keyboard drawers, our peripheral devices are available in various designs and sizes and can be customized to your requirements.
• Reliable functionality: Even in the presence of strong vibrations, temperature fluctuations, or aggressive atmospheres, our devices operate reliably and without malfunction.

Peltier cooling units operate on the principle of thermoelectric cooling and therefore do not require any cooling liquid (zero GWP). In addition, they ensure a high level of functional reliability, as they are designed in such a way that there is no exchange of air between the ambient air and the interior of the control cabinet.

Lm-therm Peltier control cabinet cooling units are the optimal solution especially in extreme ambient conditions, e.g. cramped conditions, high ambient temperatures, dirty as well as aggressive atmospheres, strong vibration and acceleration forces, and are vibration-proof.

They operate perfectly at temperatures between -20 °C and +70 °C. Peltier cooling units are suitable for both indoor and outdoor applications. The IP protection class to the outside is IP 66.

Unlike conventional cooling units, Lm-therm Peltier cooling units can be mounted in almost any position, as operation is independent of position (except roof mounting).

For Peltier cooling units, we can also offer various special solutions and modify and manufacture Peltier cooling units according to your requirements.

Lm-therm offers the following Peltier units:

• Useful cooling capacities from 30 W to 800 W
• Devices with AC (120V, 230 V) or DC (12, 24,48V)
• Protection class IP 66 or Type 4X
• Operating temperature range from -20°C to 70°C
• Stainless steel versions optionally in V2A or V4A
• Special design Peltier devices

Special version salt fog proof

Where standard is no longer possible, Lm-therm comes into play. We develop and deliver your control cabinet air conditioning or thermal management solution according to the individual requirements. We are able to provide customized solutions to your problem and develop and implement special designs in control cabinet heating and Peltier cooling solutions according to individual requirements.

Take advantage of our experience of more than a quarter of a century.
We will be pleased to advise you.
