Supporting Hygiene-Critical Processing Environments

Processing equipment can be exposed to water, steam, alkaline cleaning agents, heavy loads, temperature extremes and continuous-duty operation. Lubricants and maintenance fluids must continue to perform through these conditions while supporting the cleanliness and control required in food, beverage and pharmaceutical facilities.

Rock Oil products are designed to help:

• Support reliable equipment performance in hygiene-critical environments.
• Protect components against wear, corrosion, moisture and wash-off.
• Maintain lubricant stability through temperature variation and continuous operation.
• Reduce maintenance-related downtime and support longer component life.
• Provide practical product options across processing, packaging and clean production systems.

PRO-GUARD™ FOODSAFE Greases

Rock Oil’s PRO-GUARD™ FOODSAFE greases provide high-performance lubrication for bearings, slides, chains and other components operating under demanding conditions.

The range includes extreme-pressure greases for heavy loads and wet environments, high-temperature products for oven conveyors and heated equipment, multi-purpose and water-resistant greases for general plant lubrication, and an assembly and anti-seize product for threaded fasteners, sliding components and small open gears.

These products are designed to provide dependable mechanical stability, wear protection, corrosion resistance and resistance to water wash-off. The correct grade should be selected according to operating temperature, load, application method and environmental exposure.

Chain, Gear and Worm Gear Fluids

Conveyor systems, drive chains, gearboxes and reduction units in processing and packaging facilities can operate under continuous load while being exposed to moisture, steam, cleaning solutions and temperature variation.

INDUS-FOODSAFE™ drive-system fluids include fully synthetic chain and gear lubricants, a specialist high-temperature chain fluid and a range of PAG-based worm gear fluids. These products are developed to support film strength, wear protection, thermal stability and reliable operation across demanding drive applications.

The PAG worm gear range is particularly suited to applications involving high sliding contact, elevated temperatures and continuous operation, including conveyors, mixers, dosing equipment and packaging-line reduction units.

Hydraulic, Compressor and Vacuum Pump Fluids

Rock Oil supplies clean-running hydraulic, compressor and vacuum pump fluids for equipment used throughout food, beverage and pharmaceutical production.

The hydraulic range includes fully synthetic and PAO-based options designed to provide wear protection, oxidation stability, low-foaming performance and reliable operation across wide temperature ranges. Products are available for processing machinery, packaging lines, bottling equipment and automation systems.

INDUS-FOODSAFE™ compressor and vacuum pump fluids support rotary vane, screw and reciprocating compressors, vacuum packaging equipment, tray sealers and other systems where stable, dependable lubrication is required in hygiene-critical locations.

Heat Transfer and Refrigeration Fluids

The INDUS-FOODSAFE™ portfolio includes heat-transfer and refrigeration products for closed-loop heating and cooling systems, temperature-controlled processes and industrial refrigeration equipment.

INDUS-FOODSAFE™ HTF supports continuous heating and cooling duties in applications such as jacketed vessels, commercial bakeries, industrial ovens, heat exchangers and food-processing lines. GLYSOFOR L provides a biodegradable, low-toxicity MPG-based option for heating, cooling, antifreeze and corrosion protection in closed liquid-circulation systems.

The INDUS-FOODSAFE™ RL range provides PAO-based synthetic fluids for ammonia refrigeration compressor lubricant and coolant duties, as well as selected sealing-fluid and vacuum-pump applications.

White Oils and Specialist Maintenance Fluids

The INDUS-FOODSAFE™ range also includes high-purity white oils and specialist products for cleaning and maintenance tasks.

White oils are available in a broad selection of viscosities for food manufacturing, pharmaceutical and cosmetic applications, lubricant blending and other duties requiring highly refined, colourless and odourless mineral oils.

Supporting products include an ultra-pure degreaser for removing oils and light residues, together with a specialist sugar dissolving fluid for confectionery, bakery and pharmaceutical equipment exposed to sugar, fondant and similar deposits.

NSF H1 Aerosol Maintenance Products

Rock Oil’s INDUS-FOODSAFE™ aerosol range provides controlled application for maintenance tasks in food, beverage and pharmaceutical environments. The range includes moisture-repelling, penetrating, silicone, grease and chain-lubricating sprays.

Each aerosol is NSF H1 registered, supporting use in applications where indirect or incidental contact with food products may occur. Products should be selected according to the required task, including moisture displacement, freeing seized components, clean lubrication, grease application or chain and cable protection.

Designed for Regulated Processing Environments

The INDUS-FOODSAFE™ portfolio includes NSF H1-registered products for applications where incidental food contact may occur, alongside products formulated using components listed under relevant FDA regulations, including FDA 21 CFR 178.3570 where applicable.

Certifications, registrations and formulation details vary by product. Always refer to the latest technical documentation or contact Rock Oil to confirm that the selected product and current approval status are appropriate for the intended application.

This product-specific approach helps maintenance and engineering teams support internal procedures, specification reviews and audit requirements while selecting the correct lubricant for each item of equipment.

Clear Product Identification

The INDUS-FOODSAFE™ range uses a structured colour system to support clear product selection in documentation, stores and production environments.

A consistent white background distinguishes INDUS-FOODSAFE™ products from other Rock Oil ranges, while dedicated section colours identify families such as greases, hydraulic fluids and aerosols. Distinct label colours are also used where appropriate, helping maintenance teams locate the correct product for the task.
