WHD-FMA-NUT Capillary Thermostat With Waterproof Nut

Capillary Thermostat With Waterproof Nut Advantages

Moisture-Aware Mounting Design
The waterproof nut helps seal the mounting connection against moisture around the installation point, which is useful for equipment exposed to condensation or occasional splashing.

Remote Temperature Sensing
The 1500 mm capillary tube separates the sensing bulb from the thermostat body, allowing temperature to be detected at a different position within the equipment.

Stable Switching Behavior
The defined 3–5°C switching differential provides a controlled interval between the thermostat's switching points during normal operation.

Flexible Equipment Integration
The mechanical capillary structure can be incorporated into different refrigeration, cooling, and temperature-control systems without requiring an electronic temperature sensor or control board.

Straightforward Circuit Matching
The 250V/16A electrical configuration gives equipment designers a clear reference when integrating the thermostat into a compatible control circuit.

Capillary Thermostat With Waterproof Nut Applications

The WHD-FMA-NUT is suitable for equipment requiring temperature control in low- and moderate-temperature conditions, including:

Refrigeration units and display cabinets
Water dispensers and water coolers
Cold storage equipment
Ice makers and beverage cooling systems
Dehumidifiers
Climate control equipment
Other compatible refrigeration and cooling equipment

WHD-FMA-NUT Capillary Thermostat With Waterproof Nut FAQ
What does the waterproof nut do?

It helps seal the thermostat mounting point against moisture around the connection area. It does not represent a full-unit IP protection rating.

Is the WHD-FMA-NUT suitable for refrigeration equipment?

Yes. Its -35°C to 35°C range makes it suitable for various refrigeration and cooling control applications within the rated conditions.

Can the Capillary Thermostat With Waterproof Nut use a different capillary length?

The standard model uses a 1500 mm capillary. Other configurations can be discussed for OEM requirements.

What does the 3–5°C differential mean?

It is the temperature interval between the thermostat's switching points during operation.

Can it replace an existing mechanical thermostat?

It can be considered when the temperature range, electrical rating, bulb configuration, capillary length, and mounting requirements match the existing thermostat.

What information is needed for OEM selection?

Buyers should provide the required temperature range, capillary length, bulb configuration, electrical rating, and mounting requirements.
