Compact Double Vertical Lift Module
The Compact Double: Exclusively Distributed, Integrated, and Supported in North America by White Systems.
White Systems' Compact Double VLM
The Compact Double Vertical Lift Module (VLM) delivers ultra high density storage to maximize every square foot of your facility. Built with a metal rack and pinion system, this VLM ensures smooth and reliable tray retrieval at a convenient ergonomic height, enhancing operator safety and comfort. The safety curtain and additional safety features further ensure a secure working environment.
Watch how the Compact Double utilizes a dual-tray elevator to manage its high-density, 4-tray horizontal storage rows, providing unparalleled SKU capacity in a single vertical module.
Why Choose a Compact Double?
If speed, space, and efficiency matter to your operation, the Compact Double is the ideal solution. Its dual-tray system delivers faster picking without pauses, while vertical storage drastically reduces your floor space requirements. Built with precision mechanics and safety in mind, it enhances both throughput and workplace ergonomics. Whether you’re dealing with high SKU counts, tight footprints, or growing demand, the Compact Double gives you the performance and flexibility to keep up—without compromise.
Built for Maximum Inventory Consolidation
The Compact Double is the ideal solution for facilities managing massive SKU counts that require total organization in a restricted footprint. By utilizing a 4-tray horizontal configuration and an intelligent dual-tray elevator, it allows for the highest possible storage volume per square foot. It is the ‘Master’ unit for high-density storage, designed for operations where floor space is the most critical constraint.
Double the Speed
Dual-tray delivery keeps one tray ready while the next is retrieved, cutting wait times and boosting throughput.
Maximum Storage Volume
Optimizes every inch of vertical space with intelligent tray spacing and compact design with 4 trays per level.
Precise, Durable Motion
Rack-and-pinion drive delivers smooth, low-maintenance performance.
Ergonomic Access
Trays arrive at a comfortable height with built-in safety features to protect operators.
Compact + Scalable
Small footprint with up to 52′ of height—ideal for tight spaces and future growth.
Benefits & Solutions of the Compact Double VLM
The Compact Double Vertical Lift Modules deliver speed, space savings, and ergonomic efficiency for high-volume operations.
-
Highest Storage Density: Utilize a four-tray per level configuration to store more inventory in a single module than any other VLM in our lineup.
- Maximize SKU Density & Control: By utilizing 4-deep tray storage and a dual-tray elevator, the Compact Double provides the highest SKU density in our lineup. While the system intelligently manages tray positioning to optimize access, its primary strength is consolidating massive inventories into the smallest possible footprint.
-
Footprint Efficiency: Reclaim up to 85% of floor space by consolidating massive amounts of shelving into one high-density vertical system.
- Streamlined Picking: Combined with MILO™ software, the Double handles massive SKU counts while maintaining 99.9% accuracy and organization.
Features & How it Works
The Compact Double VLM uses a dual-tray extractor system that delivers one tray to the operator while simultaneously retrieving the next—eliminating downtime between picks. Trays are stored vertically and automatically spaced using smart height sensing to maximize density. When an operator requests an item, the system’s rack-and-pinion elevator moves quickly and smoothly to retrieve the correct tray and present it at an ergonomic access window.
Key features include:
-
Dual-Tray Delivery – Keeps picking fast by staging one tray while the other is in use.
-
Rack & Pinion Drive – Ensures smooth, precise motion and long-term reliability.
-
Smart Height Detection – Automatically adjusts tray spacing to optimize storage.
-
Ergonomic Access Point – Trays arrive at a safe, comfortable working height.
-
Safety Light Curtain – Immediately halts movement if anything crosses the access window.
-
Customizable Tray Layouts – Flexible compartments keep inventory organized and accessible.
-
WMS Connectivity – Seamlessly integrates with software for inventory tracking and control.
This system transforms your storage into a compact, high-speed, operator-friendly solution that adapts to your workflow.
