WFS-1001-H – Honeywell Water Flow Switch for HVAC Systems

Discover the WFS-1001-H Honeywell – a durable, high-accuracy water flow switch for HVAC systems. Officially distributed by DLK in Vietnam with trusted technical support.

In HVAC systems, water plays a crucial role in cooling, heat transfer, and ensuring stable operation throughout the facility. To control and protect equipment, monitoring water flow is essential. The WFS-1001-H by Honeywell is specifically designed for this purpose — to promptly detect issues, maintain steady flow, and enhance operational efficiency.
In Vietnam, DLK is the official distributor of Honeywell, offering high-quality valves and HVAC solutions, including the WFS-1001-H water flow switch.

1. Why monitor water flow in HVAC systems?

HVAC systems use water in several key processes:

• Chillers and Cooling Towers (for heat dissipation).
• Cold/hot water piping systems.
• Boilers and Heat Exchangers.

If water flow becomes unstable or interrupted, the system may face serious risks:

• Overheating, causing equipment damage.
• Reduced cooling/heating efficiency.
• Energy waste due to improper operation.
• Sudden system shutdowns.

Therefore, monitoring devices like the WFS-1001-H are vital to protect and optimize HVAC system performance.
