Series TLEX 0.5 to 4.5 - MOP at 0C (combi adsorber charge) - TEV with fixed orifice and adjustable superheat setting
 |
| TLEX 0.5 - 4.5 Thermostatic Expansion Valve with built-in orifice, solder connections, adjustable superheat setting and external pressure equalization. |
Thermostatic expansion valve for multiple injection in plants with one or more circuits, particularly for series systems such as refrigerated cabinets, deep freeze chests, freezers, fermentation interrupters, ice and cream machines, compact systems in refrigeration and air conditioning. Imperative for multiple injection by liquid distributors or for use with plate head exchangers.
