R404A GAS 0,750 Kg IN REFILLABLE CYLINDER NEW 1/4″ SAE VALVE

Description

R404A GAS 0,750Kg IN REFILLABLE CYLINDER NEW 1/4” SAE VALVE

The cylinder, new, remains your property.

Its main application is new systems for medium and low refrigeration temperatures. Theoretical cooling capacity is 5% lower than R-502 at evaporating temperatures of -40ºC. The coefficient of performance (COP) is approximately 5 to 8% lower than R-502. If superheat increases, the COP of R-404A may be higher than that of R-502. In the case of retrofits of R-502 and its HCFC substitutes (R-408A, DI-44), it is necessary to eliminate 95% of the original mineral or alkylbenzene oil, replacing it with a polyol ester oil, change the filter drier, the expansion valve, the rubber O-rings with the plastic ones and in some cases oversize the condenser. In the event that it is used as a retrofit to R-22, it will also be necessary to replace the relief valves and other items rated for the R-22 pressures.

Applications:

• average temperatures
• low temperatures
• New installations
• Retrofits

Characteristics:

• Does not damage the ozone layer, ODP = 0
• Only compatible with POE type synthetic oils.
• It is possible to fill the devices in case of leaks.
• Lower discharge temperatures than R-22, which extends compressor life.
• Cooling capacity and energy efficiency slightly lower than those of R-502.
• Superior cooling capacity and energy efficiency similar to R-22.
• Global Warming Potential (GWP) = 3922
• Boiling point at 1.013 bar (ºC): -46.45
• Glide (temperature glide) (ºC): 0.7
• Saturated vapor density at 25ºC (kg/m3): 63.28
• UN No: 3337
• Security classification: A1.
• Low toxicity and non-flammable.
• Always load in liquid phase
