Thermostatic expansion valves of the TLE and TLEX series

The thermostatic expansion valve of the TLE and TLEX series has been specially developed for refrigeration systems with one or more cooling points, such as heat pumps, chillers, refrigerated cabinets, chest freezers, freezers, fermentation interrupters, ice cream and cream makers as well as compact appliances in refrigeration and air conditioning technology.

Technical details:

• TLE: with internal pressure equalisation
• TLEX: with external pressure equalisation and mandatory for multiple injection through liquid distributor
• Combined adsorber filling as standard for various refrigerants
• Gas ballast filling for low-temperature applications
• Adjustable superheat
• Warm thermal head for high reliability
• Solder connections
• Long service life due to stainless steel head welded with inert gas and stainless steel diaphragm
• Fixed built-in nozzle
• Refrigerants: R134a, R401A, R22, R407C, R407A, R422D, R404A, R507A, R402A, R407B, R410A, R23, ISC 89, R508A, R508B (other refrigerants on request)
• Nominal output range: 0.99 to 17.0 kW R22
• Max. Ambient temperature: 100 °C
• Max. Sensor temperature: 140 °C
• Static overheating: approx. 3 K
• Capillary tube length: 1.5 m
• Sensor diameter: 12 mm

Advantages and benefits:

The thermostatic expansion valves in the TLE and TLEX series offer a wide range of benefits, including:

• Optimal evaporator defrosting for all applications
• Stable control behaviour due to adsorber filling
• Best possible overheating control due to optimum time behaviour
• Insensitivity to temperature influences

The TLEX-00490 thermostatic expansion valve is the ideal solution for anyone who needs reliable and efficient control in refrigeration systems. With its various unique features and the ability to use different refrigerants, it offers maximum flexibility and performance.
