Tuleja termostatu Honeywell „45900409-008B”

This Honeywell thermostat well 45900409-008B is designed for installing immersion temperature sensors and aquastats. It provides reliable protection of the sensing element in heating and hot water supply systems, allowing its replacement or maintenance without draining the heat transfer fluid from the system. Technical specifications: Parameter Value Part numbers 45900409-008B, 534.196.003 Manufacturer Honeywell Mounting thread 1/2" (standard for most boilers) Immersion length 103 mm Purpose Protection of temperature sensors / thermostats ✅ Key advantages: Original Honeywell quality – Full compatibility with Honeywell equipment, ensuring accurate thermal contact and correct automation operation. Easy installation – The model has a standard 1/2" threaded connection, allowing easy screwing into a prepared socket in the boiler or a tee on the pipeline. Measurement accuracy – Thin wall thickness provides minimal thermal inertia, so the sensor responds quickly to temperature changes. Corrosion resistance – The well body is resistant to hot water and standard antifreezes, ensuring long service life. Additional information: Using an original well is critical for maintaining accuracy of safety systems, as corrosion or scale on the old part impairs heat transfer and causes delay in automation response. To improve heat transfer between the well wall and the sensor, it is recommended to fill the cavity with thermal paste. Order part numbers: 45900409-008B, 534.196.003
