Immersion sleeves serve as the protective guardians of temperature sensors in demanding industrial environments. At Andivi, these precision-engineered components bridge the gap between harsh process conditions and accurate temperature measurement, ensuring reliable data collection across diverse applications.
Comprehensive Immersion Sleeve Portfolio
Andivi manufactures a complete range of immersion sleeves designed for various industrial requirements. The product lineup includes brass immersion sleeves suitable for temperatures up to +160°C with pressure ratings of 16 bar, perfect for standard HVAC applications. The stainless steel variants elevate performance significantly, with models capable of withstanding temperatures up to +700°C and pressures reaching 40 bar static.
The standard offerings feature G1/2″ thread sockets with multiple mounting lengths from 50mm to 400mm, providing flexibility for different installation depths. Specialized configurations include pressure screw options with silicone gaskets for enhanced sealing, welded designs with clamp rings, and high-temperature models with internal connecting threads. Materials range from galvanized brass for cost-effective applications to stainless steel 1.4571 for superior corrosion resistance and temperature tolerance.
Custom Engineering Excellence
Beyond standard configurations, Andivi specializes in custom immersion sleeve development tailored to specific client requirements. This capability encompasses diverse material selections, alternative thread socket specifications, various mounting lengths, and specialized designs for unique applications. Whether clients require exotic alloys for chemical compatibility, non-standard thread configurations for legacy systems, or extended lengths for deep tank measurements, Andivi’s engineering team delivers precisely engineered solutions.
Custom development extends to pressure ratings, temperature specifications, and surface treatments to match specific process conditions. This flexibility ensures optimal performance across applications where standard products fall short, providing clients with perfectly matched solutions rather than compromise alternatives.
HVAC and Building Automation Applications
In HVAC systems, immersion sleeves function like protective armor for temperature sensors, enabling accurate monitoring in heating and cooling circuits, boiler systems, and chilled water installations. Brass sleeves excel in standard building automation applications where temperatures remain moderate and corrosion resistance requirements are manageable. These installations benefit from reliable temperature feedback for control systems, ensuring optimal energy efficiency and occupant comfort.
Stainless steel variants prove indispensable in commercial buildings with higher temperature applications, such as steam heating systems, high-temperature hot water loops, and industrial HVAC installations. The robust construction protects sensors from flow-induced vibration, thermal shock, and potential chemical contamination from water treatment additives.
Industrial Process Monitoring
Industrial applications demand exceptional durability from immersion sleeves, as they must withstand aggressive media, high pressures, and extreme temperatures. Chemical processing facilities rely on stainless steel immersion sleeves to monitor reactor temperatures, distillation column conditions, and heat exchanger performance. The corrosion resistance of 1.4571 stainless steel ensures long-term reliability in environments where process fluids might attack lesser materials.
Food and beverage industries utilize sanitary-grade stainless steel immersion sleeves for temperature monitoring in pasteurization systems, fermentation vessels, and storage tanks. These applications require materials that meet stringent hygiene standards while providing accurate temperature measurement for process control and food safety compliance.
Energy and Power Generation
Power generation facilities represent some of the most demanding applications for immersion sleeves, where temperatures can exceed 400°C and pressures reach extreme levels. Steam turbine monitoring, boiler feedwater temperature measurement, and cooling system oversight all depend on robust immersion sleeve installations. The ability to replace sensors without system shutdown proves invaluable in maintaining power plant availability and operational efficiency.
Renewable energy applications, including solar thermal systems and geothermal installations, benefit from immersion sleeves that can handle wide temperature ranges and potentially corrosive fluids. These applications often require custom lengths and specialized materials to accommodate unique system configurations and environmental conditions.
