Saswell Launches 2025 Next-Gen HVAC Terminal Actuators—— Empowering Terminal Systems with Agile Customization and Intelligent Control

In 2025, Saswell officially unveils three new HVAC terminal actuators, targeting Fan Coil Units (FCU) and Underfloor Heating (UFH) systems. These innovations focus on three strategic pillars: Precision Modulation, Operational Safety, and Intelligent Hydraulic Balancing, further elevating Saswell’s solution-integrated capabilities.

With over 20 years of R&D expertise and a proven track record of co-developing products with global partners, Saswell continues to meet evolving market demands through Agile Customization and reliable delivery. This launch is a definitive showcase of that commitment.

Product 1: 0–10V Modulating FCU Actuator (SA905-V)

A continuous modulation solution for precision-driven environments

The SA905-V utilizes a stepper motor drive and supports 0–10V analog control signals. It provides continuous adjustment of valve openings based on real-time commands, ensuring stable water flow and precise indoor temperature consistency.

Key Features:

●Supports 0–10VDC continuous modulation

●Stepper motor drive: Rapid response and precise positioning

●Configurable flow characteristics: Supports Linear / Equal Percentage curves

●Bluetooth App debugging for efficient on-site configuration

●Standard M30×1.5 interface, compatible with major valve bodies

Ideal For:

Commercial buildings, luxury residences, and FCU systems requiring seamless BMS integration.

Product 2: Fail-Safe ON/OFF Linear Actuator (SA905-S)

A dedicated safety solution for power-off protection

The SA905-S is an ON/OFF Fail-Safe linear actuator engineered for the safety requirements of FCU water systems during power outages or anomalies. Featuring an integrated energy storage unit, it automatically drives the valve to a safety position upon power loss, significantly mitigating operational risks.

Key Features:

●Robust ON/OFF control with high system compatibility

●Fail-Safe Technology: Automatic reset during power failure

●High close-off force for reliable valve shut-off

●Ultra-quiet operation, ideal for noise-sensitive environments

●Standard M30×1.5 interface for easy installation

Ideal For:

Hotels, hospitals, and high-end residential projects where safety and reliability are paramount.

Product 3: New Generation UFH Actuator Series

From basic zone control to intelligent hydraulic balancing

Saswell’s new UFH lineup spans from traditional electro-thermal actuators to advanced smart stepper motor models, catering to diverse needs for cost-efficiency, comfort, and energy performance.

The flagship smart model introduces the ΔT (Temperature Differential) Auto-Regulation logic. By dynamically adjusting loop flow based on the system's operational status, it achieves automatic hydraulic balancing and resolves uneven heating issues.

Key Features:

●Stepper motor drive for micro-adjustment of loop flow

●Automatic ΔT Control: Boosts system efficiency and thermal comfort

●Low power consumption for long-term operational efficiency

●Bluetooth App for parameter setting and real-time monitoring

●Universal M30×1.5 interface for easy installation
