Heating Temperature Limiter

Heating Temperature Limiter Overview

A Heating Temperature Limiter monitors temperature and disconnects the heating circuit when a preset limit is reached. Unlike a standard thermostat used for normal temperature control, a limiter provides an independent over-temperature cutoff.

The range includes capillary, bimetal, and electronic sensing configurations for heating equipment, water heating systems, ovens, commercial appliances, and industrial equipment.

Heating Temperature Limiter Technical Specifications & Selection Factors

Heating Temperature Limiter Applications
HVAC and Air Handling

Heating Temperature Limiter products can be used in air handlers, duct heaters, electric furnaces, and heat pump auxiliary heaters to provide temperature limit protection for heating components.

Water Heating Systems

Applications include electric water heaters, tankless heating units, and hot-water circulation systems. The Intelligent Water Temperature Control Switch is used for water heating applications where temperature adjustment and switching are required.

Cooking and Oven Equipment

Ovens, sealing machines, PPR pipe welding equipment, and melting equipment can use a Degree Oven Heating Temperature Limiter for high-limit temperature cutoff.

The WHD-H2 covers 0–320°C with AC 16A 250V electrical specifications, a 6 mm sensing bulb, 300–2000 mm capillary length, and automatic reset.

Industrial Process Heating

Heating limiters are used in industrial ovens, dryers, processing chambers, heat exchange equipment, and other heat-based manufacturing equipment.

Food Service Equipment

Applications include warming cabinets, cookers, grills, and food preparation equipment where heating circuits require temperature limit protection.

Moisture and Corrosion-Exposed Equipment

The Stainless Steel Heating Temperature Limiter WHD-BP has a stainless steel configuration with a 0–120°C temperature range, 8.5 mm sensor diameter, 35 mm sensor length, and 5000 mm capillary length.

Heating Temperature Limiter FAQ

How should the temperature limit be selected?

Set the limit above the normal working temperature but below the equipment's unsafe temperature. For example, the WHD-H2 can be used for oven applications with a limit up to 320°C.

When should automatic or manual reset be used?

Choose automatic reset when temporary temperature rises are expected and automatic recovery is acceptable, such as water heaters or general heating equipment. Choose manual reset when a trip should require inspection before restarting, such as industrial ovens or sealing equipment.

When is a capillary and bulb sensor suitable?

Use a capillary and bulb sensor when the sensing point is separated from the thermostat mounting position. For example, the bulb can be installed inside a water tank while the limiter is mounted on the external panel.

How should the electrical rating be selected?

Match the limiter rating to the heating load. The standard models are rated up to AC 16A 250V; higher-load applications should be checked against the actual current of the heating element.

When is a stainless steel limiter suitable?

The WHD-BP is suitable when the application requires a 0–120°C limit range, an 8.5mm sensor, and a 5000mm capillary. Its stainless steel construction can also be specified for equipment where stainless material is required.

What is the temperature range of the Degree Oven Heating Temperature Limiter?

The WHD-H2 covers 0–320°C and uses a 6mm sensing bulb with a 300–2000mm capillary and automatic reset.

What is the difference between WHD-H2 and WHD-E2?

Both cover 0–320°C with AC 16A 250V and 6mm sensing bulbs. WHD-H2 is intended for oven applications, while WHD-E2 is the general Heating Temperature Limiter for other heating equipment.

What is the Intelligent Water Temperature Control Switch used for?

The WHD-H3 uses a manual rotary knob, making it suitable for water heating equipment where the temperature needs to be adjusted directly at the control panel.

Can the capillary length and sensor configuration be customized?

Yes. Common options include capillary length, sensor diameter, temperature setting, housing material, terminal type, and mounting configuration.

Can samples be provided before bulk production?

Yes. Samples can be used to check temperature cutoff, reset behavior, sensor position, and installation compatibility before bulk production.

What is the MOQ for Heating Temperature Limiter orders?

MOQ varies by model and customization. Standard configurations generally require less customization than orders involving new specifications, materials, or branding.

Can you provide Wholesale and OEM supply?

Yes. Supply is available for Wholesale, OEM, and ODM orders, including standard configurations and customized specifications for distributors and heating equipment manufacturers.
