| Condensation poses a particular risk for control electronics, especially with outdoor siting, but also indoors. Various different output categories ensure that the correct thermal output is always available. In this way, the total required thermal output can be distributed with complete accuracy within an enclosure. |

Units for DIN or screw mounting.
TH heaters, installed separately from cooling unit, must be connected to a TMC thermostat. When used to prevent cabinet condensate they should be electrically connected also when cabinet is off.In this cabinet it’s better to install more heating elements with small heating power.In this way there is an optimal air temperature distribution. |

The elements are specially shaped so as to obtain the best curtain type exchange surface and are fixed on a stainless steel or steel plate. Fitted with an electrical connection box separate from the plate for uses at temperatures over 120 °C, the batteries may be powered by three-phase supplies up to 750 V.
The heating elements are wired with high temperature cables, generally in busbars mounted on insulators at one or more rates.
Designed to be used at temperatures up to 850 °C, the plates may be mounted on steel or stainless casings to allow their installation on the duct network
Devices can be produced according to ATEX directives.

These are particularly suitable for heating and maintaining the temperature of large volumes or heating circulating fluids such as water, heavy fuel oil, thermal fluid, air or gas. They can be fitted on tanks, cisterns, boilers and circulation reheaters and are the best electrical heating system for a range of industries such as food processing, chemicals, textiles, plastics etc.
The stainless steel or incolloy armoured elements are generally hairpin-shaped and are welded to the DIN/ASA standardized flanges according to procedures which have CODAP, TÜV and ASME approval.
The watt density, ranging from 0.1 to 15 W/cm², is determined from the working parameters of the process and the exchange coefficients. For a maximum immersion length of 3300 mm, the power delivered by a flange immersion heater can reach several MW.
The electrical cabling in one or more paces gives access to several power steps. Connection blocks and rods are used to ensure the electrical connection.
Devices can be produced according to ATEX directives.

Teflon® immersion heater
The technology of the immersion heater Teflon®, entirely realized in their workshops, is based on a cable heating of weak load and inertia thermics, which allows a soft and precise diffusion of heat. It is then formatted so as to obtain a large surface of exchange in small overall dimensions. This weak load generates one lifespan of the immersion heater but as product heated more important as with a traditional immersion heater of higher load. The range of power S `extends from 0,5 kw to 15 kw. |

Flexible Thermofoil™ Solutions for Heating
Thermofoil™ heaters are thin, flexible heating elements consisting of an etched foil resistive element laminated between layers of flexible insulation. Since their introduction by Minco over 45 years ago, Flexible Thermofoil™ heaters have demonstrated significant advantages over conventional electric heaters.
Precise Heating
Thermofoil™ heaters put heat where you need it. You simply apply them to the surface of the part to be heated. Their thin and Flexible profile gives close thermal coupling between the heater and heat sink. You can even specify profiled heat patterns with higher watt densities in areas where heat loss is greater.
Faster Warmup and Longer Life
The flat foil element of Flexible Thermofoil™ heaters transfers heat more efficiently, over a larger surface area, than round wire. Thermofoil™ heaters, therefore, develop less thermal gradient between the resistive element and heat sink. Heaters stay cooler. The result is higher allowable watt densities, faster warmup, and prolonged insulation life. Thermofoil™ heaters can safely run at wattages twice those of their wire-wound equivalents. Insulation life may be ten times greater. For high levels of reliable heat, the obvious choice is Flexible Thermofoil.

Freeze protection for military hardware, aircraft instrumentation and hydraulic equipment
Battery heating
Foodservice equipment
Factory bonding and subassemblies

The hotflex® is worldwide the first tubular heater which can be manually bent in all three dimensions. Easiest handling, simple assembly, optimal thermal features and the simple storage (the hotflex® is supplied in straight condition with numerous lengths from stock) are outstanding product arguments.
The three dimensional bending of the hotflex® enables _towards the traditional heating (e. g. with hotrod® cartridge heaters type HHP) high flexibility.
With applications such as outline heating a better heat transition, considerable savings of the tool mass, replacements as well as lower energy consumption can be achieved.
