Danfoss RT Thermostats / differential thermostats for heavy duty applications

RT controls are used in general industrial and marine sectors.
The Danfoss temperature switch series RT consist of a variety of ordinary room temperature switches and remote sensor temperature switches including neutral zone temperature switches. RT temperature switches are generally recommended for applications where safety or economical consequences are critical factors.
RT controls have been in service for more than 60 years.

Danfoss RT differential temperature switches are used in process plants, ventilation plants, refrigeration and heating plants, where there is a need to maintain a certain temperature difference, from 0 - 20° C, between two media. One of the sensors is used as a reference, ther other as an indirect controlled variable. (The direct controlled variable is the temperature differential).
Danfoss RT differential switches

• Temperature range: 0 - 20° C
• Operating range: -30° to 100° C
• Changeover switch SPDT
• Enclosure IP66
• Available with marine approvals from the major authorities
