Description
Maximum Energy Efficiency and Overheating Control for Low-GWP Refrigerants
Refrigerant Boys’ T2 series thermostatic valve for R448A/R449A is designed to handle the specific pressure-temperature curves and glide typical of modern HFO/HFC blends introduced to replace R404A and R507. It ensures stable and responsive modulation of the refrigerant flow, guaranteeing full utilization of the evaporator’s heat exchange surface and preventing dangerous liquid slugging back to the compressor.
Strengths & Advantages:
Specific Calibration for R448A and R449A: Calibrated to compensate for the thermal glide dynamics of eco-friendly retrofit blends, maintaining constant superheat as the thermal load varies.
Sturdy Brass Body with Flare Fittings: SAE Flare male threaded connections that allow for quick, safe installations and easy maintenance without the need for brazing or welding on site.
Laser-Welded Stainless Steel Sensing Element: A diaphragm and hermetically sealed head with high mechanical strength, designed to withstand tens of thousands of thermal cycles and high operating pressures without gas leakage from the bulb.
High-Conductivity Sensor Bulb: The compact cylindrical bulb connected to the coiled capillary tube ensures immediate temperature detection on the suction line, reacting instantly to temperature fluctuations.
Fine-Tuning Adjustment Screw: Includes a manual adjustment stem protected by a hermetically sealed cap, allowing the refrigeration technician to optimize the static superheat value in the field.
Full Compatibility with POE Oils: Internal components and elastomeric seals are designed for maximum chemical resistance with synthetic polyester lubricants.
