Quest 876 High-Efficiency & High Capacity Commercial Dehumidifier

Description

Meet the Quest 876: Engineered for Superior Moisture Control

The Quest 876 is a step forward in humidity control technology. Designed with performance and efficiency in mind, it’s built to deliver powerful dehumidification in large-scale grow rooms—while reducing the number of units needed.

Why Customers Choose the Quest 876

Maximum Efficiency
Pulls up to 876 pints of moisture daily and operates at an impressive 3.1 L/kWh, cutting down both energy use and equipment costs.

Enhanced Design
An evolution of the trusted Quest 506, this model features upgraded components and expanded capacity for even greater performance.

Things to Know Before You Buy

Professional Setup Required
To ensure safety and compliance, installation must be performed by a certified professional. Ceiling-hung units should follow all local and state regulations.

Electrical Compatibility
This is a 230-volt unit that requires hardwiring. If your setup runs on 208V or 277V, a buck boost transformer will help it integrate seamlessly.

Made for Demanding Environments

Ideal for commercial greenhouses, large industrial buildings, and mission-critical storage spaces, the Quest 876 delivers round-the-clock moisture control where it’s needed most. Whether you're managing a warehouse or a military facility, it’s built to perform under pressure.
