Antunes Controls

Antunes Controls is a manufacturer of pressure switches, gas switches, and related controls for HVACR and industrial equipment applications. The company, based in the United States, produces components used in commercial cooking equipment, heating systems, and refrigeration units. Their product line includes pressure switches designed to monitor and control gas or air pressure in systems such as gas-fired burners, boilers, and ovens. These switches are typically rated for specific pressure ranges and are constructed with materials suitable for industrial environments, including corrosion-resistant housings and electrical contacts rated for reliable switching. Antunes Controls also offers single gas switches, which serve as safety shut-off devices in gas supply lines, ensuring that gas flow is interrupted when pressure conditions deviate from set points. The switches are available in various configurations, including normally open or normally closed contacts, and with different pressure set points to match system requirements. 3G Electric supplies a range of Antunes Controls replacement parts, including pressure switches and gas switches, with multiple SKUs available to cover common models used in commercial and industrial equipment. These components are sourced to meet original equipment specifications, allowing maintenance teams to replace worn or failed controls without modifying system designs. The switches are typically rated for electrical loads up to 250 VAC and can handle currents up to several amps, depending on the model. Pressure ranges vary by part number, with some switches designed for low-pressure applications (e.g., inches of water column) and others for higher pressures (e.g., PSI). Antunes Controls products are commonly found in foodservice equipment such as convection ovens, fryers, and steamers, as well as in HVAC systems for pressure monitoring in ductwork or refrigerant circuits. 3G Electric supports global procurement of these parts, offering logistics assistance for international shipments. The catalog includes both common and less-common part numbers, enabling engineers and procurement specialists to source exact replacements for existing installations. For technical buyers, key considerations when selecting Antunes Controls switches include verifying the pressure range, electrical rating, port size, and switch action (single-pole single-throw or single-pole double-throw). The switches are typically designed for panel or bracket mounting, with threaded connections for pressure sensing lines. Replacement intervals depend on operating conditions, but regular inspection of switch contacts and pressure calibration is recommended to maintain system reliability. 3G Electric does not modify or customize these components; they are supplied as manufactured by Antunes Controls.

Frequently asked questions

Common questions about Antunes Controls from 3G Electric.

What types of pressure switches does Antunes Controls manufacture?

Antunes Controls manufactures pressure switches for gas and air applications. These include differential pressure switches, single-pole switches, and switches with adjustable or fixed set points. The switches are used to detect pressure changes in systems such as gas burners, ovens, and HVAC ducts. Models vary by pressure range, electrical rating, and connection type. For example, part number 803112501 is a pressure switch with specific set points, while JD-2-RED is an air pressure switch. Selection should be based on the system's operating pressure and electrical requirements.

Are Antunes Controls gas switches suitable for use in commercial cooking equipment?

Yes, Antunes Controls single gas switches, such as part number 8101111202, are designed for use in commercial cooking equipment like fryers, griddles, and ovens. These switches act as safety devices that shut off gas flow if pressure exceeds or drops below set limits. They are typically rated for gas pressures up to a few PSI and are constructed with materials resistant to heat and corrosion. Always verify the switch's pressure rating and electrical specifications match the equipment's requirements before installation.

What electrical ratings do Antunes Controls pressure switches typically have?

Antunes Controls pressure switches are generally rated for AC voltages up to 250 VAC and currents up to 15 amps, depending on the model. For example, switches used in HVACR applications often have ratings of 120 VAC or 240 VAC at 5 to 10 amps. The exact ratings are specified on the product label or in the manufacturer's datasheet. It is important to ensure the switch's electrical capacity exceeds the load it will control to prevent contact failure.

How do I identify the correct Antunes Controls replacement switch for my system?

To identify the correct Antunes Controls replacement switch, check the manufacturer part number on the existing switch. This number is typically printed on a label or stamped into the housing. Common part numbers include 803112501, 8021204007, and 8101111202. Cross-reference the pressure range, port size, and electrical ratings with the system's specifications. If the part number is unreadable, measure the pressure set point and compare with available models. 3G Electric's catalog lists multiple SKUs with corresponding part numbers for easy matching.

Can Antunes Controls switches be used in outdoor or wet environments?

Antunes Controls switches are primarily designed for indoor use in controlled environments. They are not typically rated for direct exposure to water or extreme weather unless specified. For outdoor applications, the switch should be installed in a weatherproof enclosure to protect against moisture and debris. Check the product datasheet for any IP rating; most standard models do not carry an IP rating. If the switch will be exposed to condensation or washdown conditions, consider using a protective cover or selecting a switch with sealed contacts.
