Honeywell TLE PRODUCT DATA
Series TLE
THERMOSTATIC EXPANSION VALVES FIXED ORIFICE, ADJUSTABLE SUPERHEAT SETTING
TLE
TLEX
Application
Thermostatic expansion valves series TLE and TLEX are used in plants with one or more refrigerant circuits, in particular for series systems such as heat pumps, refrigerated cabinets, deep freeze chests, freezers, fermentation interrupters, ice and cream machines, compact systems in refrigeration and air conditioning.
PRODUCT DATA
Features
•TLE: with internal pressure equalisation; for single injection in installations with one or more cooling circuits.
•TLEX: with external pressure equalisation; for optimal evaporation effectiveness in all applications. Obligatory for multiple injection by liquid distributors.
•Combi adsorber charge as standard
The same valve can be used for different refrigerants (see table on page 2)
Controller charge is high sensitive and responsive thus lowest possible level of superheat can be achieved
Charge is not sensitive to effects of temperature on the capillary tube and valve head
damping characteristic results in stable control behaviour
•Gas charge for deep freeze applications
•Adjustable superheat setting
•Warm thermal head provides best reliability
•Solder connections
•Extreme durable due to stainless steel head and stainless steel diaphragm welded using protective gas
•Fixed orifice
•Refrigerants: R134a, R401A, R12
R22, R407C, R407A, R422D
R404A, R507A, R402A, R407B, R502

Thermal systems with adsorber charge are completely insensitive to effects of temperature on the capillary tube and valve head. It reacts only according to the temperature of the bulb.
Thus, Honeywell TLE and TLEX valves with combi adsorber charge work absolutely reliable, even in icy condition or while defrosting using hot gas.

With gas charged valves and MOP it is under all operating conditions necessary that the bulb is always colder than the capillary tube and the thermal head!
With the Honeywell TLE and TLEX series the thermal head is heated advantageously by the liquid refrigerant. The warm thermal head is on the safe side at any time.
