Oil Minder® Systems for Elevators: Intelligent Protection for Safety, Compliance, and Environmental Responsibility

---

Elevator pits are among the most vulnerable areas in any building. Located at the lowest point of the structure, they naturally collect water from groundwater seepage, cleaning processes, leaks, or fire sprinkler activation. Without proper management, this accumulation can cause equipment corrosion, electrical failures, and costly downtime.

The Oil Minder® Control and Pump System provides a fully customizable solution for oil and water sensing and containment, helping facilities maintain safe operations while preventing harmful contaminants from entering sewers, rivers, and waterways.

Designed for durability and minimal maintenance, Oil Minder® systems deliver reliable performance in even the most challenging conditions.

Elevators rely on sump pumps to keep pits dry and operational. In many cases, these pumps must handle up to 3,000 gallons per hour, especially during emergency sprinkler activation.

Key Reasons Elevator Pumping Systems are Essential:

• Safety & Code Compliance: According to ASME A17.1 safety codes, elevator pits used for fire service operations require sump pumps or drains, often capable of discharging 50 gallons per minute (GPM) during emergencies.
• Preventing Water Damage: Persistent moisture can rust safety components such as buffer springs and limit switches, threatening elevator reliability.
• Environmental Protection: Hydraulic elevators can leak oil into pits. Without detection technology, contaminated water could be discharged into public sewer systems.
• Operational Reliability: Keeping pits dry protects critical equipment, reduces maintenance costs, and ensures continuous elevator performance.

Why Oil Detection Matters in Elevator Pumping Systems

• Submersible sump pumps remove accumulated water directly from the pit.
• Oil-sensing pumps, like Oil Minder®, go a step further, detecting hydrocarbons and preventing environmental contamination while triggering alarms for fast intervention.

Engineered for performance and reliability, Oil Minder® systems deliver several critical advantages.

Key Features & Benefits:

• Self-cleaning, maintenance-free conductivity probes
• Plug-and-play multi-pin connector for fast, simple installation
• Push-to-test diagnostic feature for dependable operation
• Fully compatible with Industrial Flow Solutions’ Stancor® line of submersible pumps
• UL-certified components
• Modular design for customized performance and cost efficiency
• Compliance with ASME A17.1 elevator safety codes
• Meets SPCC (40 CFR Part 112.7) EPA requirements

How the Oil Minder® System Works

The system operates automatically to protect both your facility and the environment:

1. Water rises and contacts the sensor probe while lifting the float, activating the pump.
2. The pump continues removing water from the sump.
3. Pumping stops when either:
   • Water drops below the probe, or
   • Oil contacts the probe, eliminating conductivity.
4. The pump shuts off before oil is discharged, leaving approximately 3 inches (76.2 mm) of liquid in the sump.
5. If water rises again, the oil floats above the probe, and pumping resumes. Audible and visual alarms provide clear operational alerts.

Flexible System Design for Any Facility

Oil Minder® systems are engineered for adaptability across elevator shafts, building trades, and electric utilities—including substations, transformer vaults, and moats.

• Simplex or Duplex Configuration:

• Simplex: A cost-effective single-pump solution.
• Duplex: Provides redundancy or separates water and hydrocarbon handling for greater flexibility.
• Vertical Probe: The OM300 vertical probe and float assembly allow installation in sump pits as small as 12 inches (304 mm) in diameter.
• Heater Option: For colder climates, a sump heater prevents freezing—ensuring uninterrupted operation year-round.
• Advanced Monitoring and Control: Modern facilities demand visibility and rapid response. Oil Minder® delivers both.
  • BACnet integration connects directly to your Building Monitoring System (BMS).
  • Dry contacts alert operators to oil faults and high-water levels.
  • Audible and visual alarms ensure issues are detected immediately.

Built for Reliability. Designed for Protection.

The Oil Minder® Control and Pump System efficiently manages water from hydraulic elevator pits and transformer vaults, safeguarding infrastructure and ecosystems.

By eliminating the need for ancillary oil-water separators and reducing maintenance demands, the system provides a smarter, more sustainable approach to fluid management.

For facilities where downtime, environmental risk, and code violations are not an option. Safety, compliance, and environmental responsibility matter. Oil Minder® delivers intelligent pumping you can trust.
