Besides its inherent inertness, improved system efficiency and higher productivity, the performance advantages of the RHB Series versus naphthenic oils include:

(1) Partial miscibility and solubility with CFCs, HCFCs and ammonia for improved oil return to the compressor;

(2) Superior system cleanliness and lubricity to reduce component wear and corrosion;

(3) Superior chemical and thermal stability;

(4) Lower foaming tendency; and

(5) Extended oil drain capability.

RECOMMENDED USES

Summit’s RPE Series fully synthetic refrigeration lubricants were designed for use in refrigeration compressors using R-134A and other HFCs as the refrigerant. They are miscible with all HFCs, HCFCs, CFCs and blends.

• NSF H1 Pending and meets USDA 1998 (H1) guidelines (lubricants with incidental food contact)
• Lower wax content versus the “essentially” or “virtually” wax free oils marketed by competitors
• Reduced oil carryover
• Superior cleanliness
• Superior chemical and thermal stability
• Enhanced wear protection
• Lower foaming tendency
• Extended oil drain interval capability
• Less oil make-up

RECOMMENDED USES

Summit RHT FG-68 is exceptionally well suited for rotary screw and reciprocating compressors in ammonia service. It is compatible with naphthenic and other hydrotreated paraffinic-based compressor oils for ammonia service, as well as PAO and alkylbenzene-based products. It is compatible with all seal elastomers commonly used in these systems including Buna-N, NBR and Neoprene.

• Solubility of gas in the lubricant causes reduced lubricant viscosity resulting in cylinder scoring and high wear rates. Compensating for this with a higher viscosity lubricant can cause handling problems at lower temperatures.
• Absorption of lubricant into the gas stream results in high lubricant usage rates and a depletion of protective lubricant film in the cylinder.
• Condensed hydrocarbon liquids in the cylinder area can “wash” the lubricant from the cylinder walls causing severe mechanical damage.
• The carryover from increased lubricant feed rates or use of heavily compounded oils to compensate for hydrocarbon and CO2 dilution and wash-out can damage the well formation and plug CO2 injectors.
• Gases such as CO2 and H2S may be corrosive to compressor components. NGL protects against the corrosive effect of these gases to compressor components while maintaining lubricating properties.

NGL Series lubricants are extremely resistant to hydrocarbon and CO2 dilution and absorption of the gas stream components. Any lubricant carryover will not impair the well formation as it is compatible with well-bore treatment fluids and soluble in water. The result is a lubricant maintaining the proper viscosity for wear protection, resisting wash-out and carryover, and posing no threat of damage to the well formation or CO2 injectors. The extremely high viscosity index of the NGL Series lubricants allows protection over a broad temperature range. The low pour point provides all-season ease of handling even in very cold climates. The use of pressurized and heated tanks as well as heat traced lines can be eliminated. Summit NGL Series can offer these same advantages when compressing a number of other difficult gases including hydrogen, helium and nitrogen. Please contact your Summit representative with your specific gas application.

RECOMMENDED USES

Summit NGL Series can offers advantages with reciprocating compressors pumping natural gas, carbon dioxide and a number of other difficult gases, including hydrogen, helium and nitrogen.

Your benefits at a glance

• Low solubility in ammonia
• Excellent flow characteristics at low temperatures
• Lower maintenance costs due to long oil change intervals and reduced oil consumption
• Easier changeover due to neutral behaviour towards seals
• High refrigeration efficiency due to reduced oil deposits
• Lower operating costs due to long filter and oil separator lifetimes
• Lower oil carryover than with naphthene-based mineral oils
