Problems can occur with strong temperature fluctuations or very low ambient temperatures. A frequent consequence is condensation and thus a risk of failure, malfunctions or malfunctions.
Lm-therm control cabinet heaters ensure stable temperatures, prevent damage due to condensation, frost and uneven temperature distribution on the components and housing. Whether control cabinet heaters with integrated thermostat, PTC control cabinet heaters, control cabinet heaters with fan or special solutions: Lm-therm delivers the perfect solution.

Our original Lm-therm control cabinet heater, invented by our Lm-therm company founder Leo Möskes, has ensured functional and safe thermal management for over 60 years.

Our new PTC control cabinet heater P70 offers:

• a quick mounting by clip fastening and pressure clamp
• an optional touch protection
• a wide voltage range
• an optimal temperature distribution

We offer the following for control cabinet heaters:

• Control cabinet heaters with integrated thermostat
• Control cabinet heaters with connection cable
• PTC switch cabinet heaters
• Fan heaters up to 1300 W
• Fan heaters up to 8,000 W
• Special solutions for housing, connection technology and connection cable
• Own developments on customer request

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

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

Filterfans avoid unwanted heat pockets and protect the electronics. Filterfans 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 filterfans in a wide range of sizes. The filterfans 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.

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.
