Siemens Building Technology ASZ6.6 Heating Element
The Siemens ASZ6.6 Stem Heating Element is a critical field-installed accessory designed to maintain operational integrity in chilled water and low-temperature process applications. This 24V AC/DC heating element delivers a constant 30W output to prevent ice formation on the valve stem when handle media temperatures drop below 32°F (0°C). By effectively eliminating frost buildup, the ASZ6.6 ensures that the valve actuator can operate without increased friction or seizing, protecting the sealing packing and preventing premature mechanical failure of the stem heating assembly.
Engineered for versatility, this stem heater is compatible with Siemens Flowrite valves and Acvatix actuators featuring stem diameters of 10 mm or 14 mm, including the SAX, SAV, and SKD/SKB/SKC series. The unit mounts directly to the valve neck and requires a separate power source to ensure the stem remains clear even during actuator standby. For optimal thermal management, do not insulate the actuator bracket or valve stem when the ASZ6.6 is installed, as maintained air circulation is required for safe operation and to prevent overheating of the BTU output components.
Key Benefits for the Field- Ice Mitigation: Prevents stem freezing and damage to the packing gland in media conditions below 32°F (0°C).
- Universal Compatibility: Fits a wide range of Siemens actuators and valves with 10 mm and 14 mm spindle diameters.
- Robust Performance: Provides reliable 30W heating capacity to handle rigorous industrial and commercial chilled water systems.
- Simplified Installation: Designed for rapid field mounting on existing valve-actuator assemblies with basic hand tools.
Can I use the ASZ6.6 with 120V power systems?
No, this heating element is specifically rated for 24V AC/DC. Using higher voltage will result in immediate component failure.
Does this heater require its own power supply?
Yes, the ASZ6.6 heating element must be powered separately from the actuator to ensure constant frost protection, regardless of the control signal state.
Should I insulate the valve stem after installing the heater?
Absolutely not. Insulation can trap excessive heat, leading to temperatures reaching up to 248°F (120°C), which may damage the actuator or become a fire hazard.
