Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Pressure Monitoring & Control: Designed to regulate pressure in HVAC systems, refrigeration units, and industrial machinery by switching circuits at predefined thresholds.
  • Media Compatibility: Supports fluids like refrigerant, oil, motor oil, transmission oil, air, and water, ensuring versatility across applications.
  • SPDT Contact Switching: Enables flexible circuit control with a single-pole, double-throw configuration for reliable on/off functionality.

Key features

  • 1. Corrosion-Resistant Brass Construction

    • With a corrosion-resistant brass body, ensure long-lasting durability in harsh environments such as HVAC systems and refrigeration units. The robust material withstands exposure to oils, refrigerants, and moisture, outperforming plastic-based alternatives in longevity*.

  • 2. SPDT Contact Arrangement for Flexible Circuit Control

    • With a SPDT (Single Pole Double Throw) contact design, easily configure circuits for multi-functional control, such as activating alarms or switching between safety modes. This design offers ~30% more adaptability than standard SPST switches*.

  • 3. High-Pressure & High-Current Capacity

    • Supporting up to 5000 psi and 40.2A, handle extreme pressure and load demands in industrial applications. This exceeds the capacity of standard 3000 psi switches, ensuring reliability in heavy-duty systems like air conditioning compressors*.

  • 4. Tailored for HVAC & Refrigeration Systems

    • Designed specifically for HVAC and refrigeration applications, this switch ensures precise pressure control in critical cooling environments. Its compatibility with refrigerants and motor oils makes it ideal for commercial and industrial use cases.

  • 5. Compliance with Industrial Safety Standards

    • Built to meet safety requirements for high-voltage systems (120VAC/240VAC), this switch ensures safe operation in commercial and industrial settings. Its waterproof seal and robust construction align with industry norms for durability and reliability.

Supplier's note

  1. Technical Breakthroughs:

    • Brass Construction: Ensures corrosion resistance in wet or corrosive environments.
    • SPDT Contact: Enables dual-state control for advanced circuit integration.
    • 5000 PSI Capacity: Exceeds industry standards for heavy-duty applications like industrial compressors.

  2. Version Selection Guide:

    • Base Model: Ideal for standard HVAC and refrigeration systems requiring 5000 PSI reliability.
    • Advanced Model: Perfect for high-current industrial machinery (e.g., hydraulic systems) needing 46.2A and 480VAC support.
    • Pro Model: Designed for extreme environments (e.g., deep-well pumps) with 6500 PSI and 600VAC ratings, ensuring safety in hazardous conditions.

With the Pro’s 6500 PSI rating—30% higher than the Base—you can safely monitor high-pressure hydraulic systems. Pair its 52.3A capacity with oil-resistant brass to ensure uninterrupted operation in harsh industrial settings. For HVAC technicians, the Base Model’s 40.2A and 240VAC compatibility streamline installation in standard commercial systems.
