SUNISO^® 4HT

• Low Oil Volatility: Reduces lubricant consumption and maintenance costs.
• Low Solubility In Ammonia: Improves system efficiency and performance.
• Excellent Thermal Stability: Extends fluid life, helping to reduce maintenance costs and downtime.
• Low Wax Content & High Viscosity Index: Excellent low-temperature fluidity with no waxy deposits to plug the system.
• Seal Compatibility: Suniso 4HT is neutral toward common seal materials. If converting from a naphthenic lubricant, please consult your Technical Services Advisor.

Suniso 4HT is designed for use in commercial and industrial refrigeration systems charged with ammonia (R-717) refrigerant. Ideally suited for low-temperature systems where evaporator temperatures are as low as -36°C / -33°F, Suniso 4HT is an excellent option for use in industries such as cold storage warehouses, food and beverage processing, flash freezing, ice rinks, etc.

Suniso 4HT is neutral toward common seal materials. If converting from a naphthenic lubricant, please consult a Petro-Canada Lubricants Technical Service Advisor.
