Medium Watt Density Cartridge Heaters
(download brochure) (download install guide)
Hotset’s medium watt density cartridge heaters are a value alternative to a high watt density heater. Medium watt density cartridge heaters are the right choice for high temperature applications that do not require integrated thermocouple, precise wattage distribution, are less than 65 watts per square inch on the heater sheath, and have lengths greater than 7 inches.
Don’t let the fact that this is a value line lead you to believe this is of lower quality than that of a high watt density cartridge heater. Medium watt density heaters feature a similar construction as a low watt density heaters with spiraled resistance wire inside of ceramic--but unlike low watt density cartridge heaters you may see in the market place, Hotset’s medium watt density heaters swaged, compacting the ceramic and MGO for improved durability and faster response.
| Options | High Watt Density | Medium Watt Density | Low Watt Density |
| Thermocouple J or K | Yes | No | No |
| Highly compressed MgO | Yes | Yes | No |
| Internally connected leads | Yes | Yes | Yes |
| Swaged leads | Yes | Yes | No |
| Wattage Distribution | Precise | Yes | No |
| High movement applications | Yes | Yes | No |
| 12v, 24v, 48v compatible | Yes | Yes | Yes |
For more simple applications that don’t require precise heating wattage distribution the medium watt density cartridge heater is a durable high value alternative. Built to Hotset exacting standards, the medium watt density cartridge heater is a proven performer.
Hotset can work with you to improve the durability of your medium watt density heater.
Do your failed cartridge heaters have similar characteristics? If so they hold clues as to the root cause of failure. Hotset can evaluate your failed heater and identify the right configuration to improve durability.
Replacement heater
Hotset medium watt density cartridge heaters allow you to build Hotset quality into your equipment without the premium cost.
The Hotset cartridge heater configurator puts the engineering tools in your hands to design the correct cartridge heater for you application specific needs. This program guides, and informs you on design criteria with an easy to use graphical interface. In less than 2 minutes you can engineer your heater.
