About Thermostats & Temperature Switches
Thermostats and temperature switches switch an electrical contact at a set temperature to control heaters, fans and compressors or to shut down equipment safely. Seven Star LLC, an independent supplier in Muscat, supplies these devices from JUMO, Danfoss, Raychem, Hydac, Industrie Technik, Trafag, Barksdale, GESTRA, Chromalox, Murphy and SAUTER to customers in Oman and the GCC.
Types of thermostat in this category
Industrial thermostats such as the Danfoss RT 14, KP 61 and MBC 8100, JUMO heatTHERM and frostTHERM and Trafag EXAS explosion-proof room thermostats control heating, cooling and frost protection. Safety temperature limiters like the JUMO safetyM STB/STW and TB/TW and GESTRA TRS 5-50 (SIL 3) protect boilers and heaters. Electronic temperature switches including the Hydac ETS and Barksdale BTS3000, bimetal switches, heat tracing thermostats from Raychem and Chromalox, and panel controllers from Industrie Technik complete the range.
How to select a thermostat
Define the setpoint range, switching differential, sensor type (bulb and capillary, rod, surface or room) and contact rating. For safety functions specify a type-tested limiter to EN 14597 and any SIL level. Check enclosure rating, process connection and hazardous area approval.
Data needed for a quotation
Send the model or code, or setpoint range, sensor type, capillary length, contact rating, approvals and quantity.

Frequently Asked Questions
What is the difference between a thermostat and a safety temperature limiter?
A thermostat controls temperature by switching on and off. A safety limiter latches off when a limit is exceeded and needs manual reset.
Which thermostats are used in refrigeration?
Danfoss KP and RT thermostats are common for cold rooms, condensers and frost protection.
What is EN 14597?
The European standard for temperature control and limiting devices on heat generating systems.
Are explosion-proof thermostats available?
Yes. Models such as the Trafag EXAS and JUMO exTHERM are designed for hazardous areas.
What should I send for a quotation?
The model, or setpoint range, sensor type, capillary length, contact rating, approvals and quantity.
