Thermocouples, Thermostats and the Spare Parts That Keep Heating Systems Alive

A boiler is only as reliable as its sensors. This 349-item section from 116 suppliers is the maintenance backbone of the HVAC catalogue: thermocouples and temperature sensors (107 positions), boiler and water heater spare parts (67), thermostats (62), electronic temperature controllers (36), pipe insulation and fittings, thermostatic expansion valves, heat meters and metering assemblies. It is the category service companies and wholesalers come back to monthly, not once a project.

Russian instrument plants have produced temperature sensing equipment for power stations and process industries for decades, so the depth here is real: industrial thermocouples in numerous junction types, lengths and thermowell materials, calibrated against GOST standards and supplied with verification documents when required. Pricing on sensors and controls typically undercuts European catalogue brands by a wide margin, which matters when you buy them by the hundred.

• Sensors: thermocouples and RTDs in standard and custom lengths, with thermowells
• Controls: mechanical thermostats and electronic controllers for heating equipment
• Metering: heat meters and apartment-level metering units for billing projects
• Spares: elements, gas valves, boards and fittings for boilers and water heaters
• Shipping: light parcels go by air courier in days; bulk orders by truck or sea, EXW/FOB
