Product Features

  • Hermetic leak‑proof construction with mass‑spectrometer leak testing for ultra‑low external leakage rate
  • Corrosion‑resistant stainless‑steel power sensing element to prevent premature valve failure
  • Compact form factor for installation in space‑constrained equipment enclosures
  • Adjustable superheat setting for fine‑tuning on‑site system commissioning
  • Optimised metering performance for R134A medium‑temperature refrigeration circuits
  • Supports internal equalizer configuration for standard evaporator layouts
  • Robust build for continuous duty in commercial refrigeration and HVAC environments

Specific Application Scenarios

  1. Commercial reach‑in coolers: Used by refrigeration technicians servicing convenience‑store beverage coolers; maintains stable cabinet temperature under frequent door‑opening load swings.
  2. Walk‑in medium‑temperature cold rooms: Deployed by facility maintenance teams for grocery and food‑storage cold rooms to protect compressors during variable cooling demand.
  3. Refrigerated display cases: Installed by HVAC‑R contractors for supermarket open display cases, preventing evaporator flood‑back during peak operation.
  4. Light‑duty air‑conditioning & heat‑pump service jobs: Used by repair trades during system retrofits or component replacement for R134A‑based HVAC assemblies.
  5. Portable commercial refrigeration units: Specified by equipment rebuilders for mobile cooling systems that face fluctuating ambient temperature conditions.
