Honeywell TLE PRODUCT DATA
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.

THERMOSTATIC EXPANSION VALVES
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

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.
