User manual HONEYWELL TBE 0.5-4.5 INSTALLATION

[. . . ] · 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 TBE 0. 5-4. 5 0. 5-4. 5X 0. 5 - 4. 5 two-way 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 TBE 0. 5-4. 5 0. 5-4. 5X 0. 5 - 4. 5 angle · Warm thermal head provides best reliability · Flare 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 Further refrigerants on request. Application Thermostatic expansion valves series TBE 0. 5-4. 5 0. 5-4. 5 are used in plants with one or more refrigerant circuits, especially for series installations mobile air-conditioning and cooling units with flare connection, e. bus AC, train AC, transport cooling.

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 TBE 0. 5-4. 5 0. 5-4. 5 series the thermal head is heated advantageously by the liquid refrigerant. The warm thermal head is on the safe side at any time. Further refrigerants on request. · Do not bend or squeeze the bulb when tightening the bulb clamp!Information for original equipment manufacturers: The valve series TBE 0. 5-4. 5 0. 5-4. 5 can be customised to the requirements of your series device in an optimum way. Contact us! Superheat Adjustment (Two-way Valve) In general the Honeywell valves should be installed with the factory setting for the used refrigerant unaltered. This superheat adjustment is calibrated for lowest superheating and optimum evaporator utilisation. However, should it be necessary to adjust the superheat, turn the adjusting spindle as follows: Turning clockwise Turning counterclockwise = = reduced refrigerant mass flow, increase of superheat increased refrigerant mass flow, decrease of superheat One turn of adjusting spindle alters superheat setting by approx. Increase of superheat setting results in a lower MOP-value and vice versa.
