Saginomiya pressure switches and controls from Japan deliver unmatched precision and reliability for HVAC and refrigeration systems. Boulton Trading Corporation proudly imports these premium Japanese engineered components, trusted worldwide for their durability in demanding applications.
Saginomiya’s Engineering Heritage
Established in 1954, Saginomiya has built a global reputation for electromechanical controls, particularly pressure switches that protect compressors and ensure safe system operation. Their R&D focus on micro-switch technology and bellows design has made them the choice for OEMs in air conditioning, commercial refrigeration, and industrial chillers.
Technical Excellence in Pressure Controls
Saginomiya pressure switches feature stainless steel diaphragms or bellows for corrosion resistance and fatigue-free performance across thousands of cycles. Models like the SNB seriesoffer adjustable setpoints from 0.2 to 30 bar, with differential settings as low as 0.3 bar for precise cut-in/cut-out control.
Key technical advantages include:
- Dual pressure operation: High/low pressure protection prevents compressor slugging or overpressure, with auto-reset or manual reset options.
- Wide temperature range: Reliable from -40°C to +120°C, ideal for low temp freezers and high ambient AC units.
- Electrical ratings: Up to 10A/250VAC, with gold plated contacts for low voltage DC signaling in modern controls.
- Refrigerant compatibility: Approved for HFCs, CO₂, and hydrocarbons, meeting global safety standards like UL and CE.
Popular configurations cover:
- LP switches (e.g., 0-6 bar) for evaporator pressure control and oil safety.
- HP switches (e.g., 10-40 bar) for condenser protection.
- Differential pressure switches for oil flow and filter monitoring.
Benefits for System Performance
These controls minimize nuisance trips while providing fast response (<1 second) to pressure anomalies, extending compressor life and reducing service calls. Their compact designs fit tight equipment spaces, and field-adjustable knobs simplify commissioning without special tools.
