Honeywell TOE PRODUCT DATA

FIXED ORIFICE, O-RING CONNECTIONS

TOEX 0.5 - 4.5 two-way

TOEX 0.5 - 4.5 angle

Application

Thermostatic expansion valves series TOE(X) are used in plants with one or more refrigerant circuits, especially for series installations, mobile air-conditioning and cooling units with O-ring connection, e. g. bus AC, train AC, transport cooling.

THERMOSTATIC EXPANSION VALVES

PRODUCT DATA

Features

• TOE: with internal pressure equalisation; for single

injection in installations with one or more cooling circuits.

• TOEX: 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

• Optional available with gas charge and MOP

• Adjustable superheat for two-way construction

• Fixed superheat setting for angle construction

• Warm thermal head provides best reliability

• O-ring connections

• Extreme durable due to stainless steel head and

stainless steel diaphragm welded using protective gas

• Fixed orifice

• Refrigerants: R134a

R22, R407C, R422D R404A, R507A Further refrigerants on request.

Refrigerant

R134a +15 °C to -30 °C 34 37.4

R22, R407C, R422D +15 °C to -30 °C 36 39.6

R404A, R507A ±0 °C to -30 °C 36 39.6

Further refrigerants on request.

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 TOE(X) valves with combi adsorber charge work absolutely reliable, even in icy condition or while defrosting using hot gas.

3. Gas charge

Refrigerants and MOP on request. 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 TOE series the thermal head is heated advantageously by the liquid refrigerant. The warm thermal head is on the safe side at any time.
