3. Product details:

R438A is a simple to use, the ODP zero (ozone depletion potential) of HFC refrigerants, can directly replace R - 22 at moderate temperature in direct expansion (DX) refrigeration equipment, including business systems, supermarket and fixed direct expansion (DX) type air conditioning equipment, including DX water-cooling chiller.

Application:

Medium temperature and low temperature of commercial, industrial, direct expansion refrigeration system (DX), including:

Residential and commercial air conditioning system; Household air conditioning; Air source heat pump water heater;

Direct expansion (DX) type is the best choice for water-cooled machine

Advantages:

Provide a simple, efficient and economic directly replace - R - 404 - a, R - 507, R - 407 - c is easier to replace

HFC refrigerants, zero ODP value;

Compatible with traditional and new lubricating oil. In most cases, the process of replacement without replacement lubricating oil type;

So far, all of the field test was successful, and without temperature control expansion valve replacement; Still can continue to use Existing equipment

Than the R - 404 - a and R - 404 had a 30% lower global warming potential (GWP)

After filling is used, if discover the refrigerant in the system capacity is insufficient, can be directly to make up, without row has complete pump refrigerant

Performance:

In most systems, has a very close to that of R - 22 refrigeration capacity and efficiency

Than R - 22 lower exhaust temperature, can prolong the life of compressor

Under the condition of low temperature, than R - 22 refrigeration capacity and efficiency as high as 16% up to 8%

In medium temperature conditions and super-cooling degree is 6 ° C, R438A refrigeration energy consumption about 8% less than R - 22, but the efficiency and R - 22.

Compared with R22 R438A advantage:

Unique HFC refrigerant R438A combines R22 pressure enthalpy characteristics and mineral oil compatibility, can be used to replace R22 in the vast majority of the temperature of the evaporator. As a substitute R22 R438A have wide application range, and is superior to other R22 alternative. R438A design closely match the pressure, temperature, enthalpy, mass flow performance, become R22 perfect replacements. R438A with R404A on global warming potential (GWP) value is less than 42%. R438A matching of r22 system capacity and efficiency, and significantly reduce exhaust temperature, could extend the service life of compressor. It is compatible with both traditional and new lubricant, provide efficient and effective replacement of r22. Note: R438A is a direct replacement the best mixed refrigerant R22.

4. Packaging specifications: 11.3 kg / 25 lb disposable cylinders

5. Product selection deadline:

R438A refrigerant ODP is zero, so is not affected by the Montreal "draft regulations obsolete material in control.

6. Lubricating oil use advice:

R438A compatible with traditional and new lubricating oil, including: mineral oil (MO), alkyl benzene lubricating oil (AB), and ester lubricant (POE). In most cases, the replacement process without replacement lubricating oil type.
