When you are servicing large-scale commercial refrigeration systems, the Danfoss 067B3210 TEX 12 Thermostatic Element is a critical component for maintaining precise superheat control. This element, often identified by the alternate part number 067B321000, is engineered specifically for the TE 12 expansion valve series. Optimized for R22 and R407C refrigerants, it operates efficiently within a wide evaporating temperature range of -40°F to +50°F (-40°C to +10°C). As a veteran technician knows, the integrity of the power element is paramount; Danfoss utilizes advanced laser welding technology in the construction of this brass-bodied unit to ensure a hermetic seal against system pressure. Featuring an externally equalized design with a 1/4 inch flare connection and a 118-inch (3000 mm) capillary tube, this thermostatic expansion valve part provides the dependable modulation required for evaporators in chillers and cold storage applications. Replace your worn 067B3210 elements to prevent compressor slugging and optimize your HVACR system performance. Key Benefits Refrigerant Compatibility: Specifically designed for R22/R407C systems to ensure accurate pressure-temperature response. Robust Construction: Laser-welded stainless steel diaphragm and brass body provide superior resistance to high working pressures up to 400 psig. Extended Reach: Includes a 3-meter capillary tube for flexible bulb placement on the suction line. Precise Equalization: 1/4 inch flare external equalization connection allows for accurate monitoring of evaporator outlet pressure. Broad Application: Suitable for a wide range of commercial refrigeration and air conditioning cooling loads. Common Questions Is the 067B3210 interchangeable with the 067B321000? Yes, both part numbers refer to the exact same Danfoss TEX 12 thermostatic element and are fully interchangeable in the field. What is the maximum working pressure for this element? The unit is rated for a maximum working pressure (MWP) of 28 bar or approximately 400 psig, making it suitable for standard R22 and R407C operating envelopes. Can this element be used with R404A or R507A? No, this specific element is charged for R22 and R407C. Using it with R404A or R507A will result in incorrect superheat settings and potential system instability.
