Spectrum Oil Storage System – Essential Stack

Essential Stack Oil Storage System

The Essential Stack provides a budget friendly and space saving solution.

The Essential Stack System is designed to easily and effectively identify, handle, store and dispense lubricants. It is an economical way to save space on a plant floor, while keeping lubricants organized and contaminant free.

It also eliminates the potential for mess and mishandling by keeping each fluid clearly identified with Trico’s exclusive color-coded tags and labels, part of the Spectrum Visual Lubrication Management line of products. Each label features a space to identify the specific substance contained within each tank, ensuring the right lubricant is delivered to the right equipment every time.

The Essential Stack System is ideal for any plant size as it is flexible to space requirements. It is available in two tank stack configurations – with a maximum of six tanks per system to meet various bulk storage needs. The Spectrum Oil Storage System provides centralized oil storage and dispensing. The 65-gallon tank capacity eliminates the cost of wasted space, time, labor, and unnecessary equipment purchases required when using 55-gallon drums.
