Product Introduction

The mobile cleanroom dehumidifier packages a refrigeration coil, hot-gas defrost circuit, fan, filter and condensate collection system in a narrow wheeled cabinet. A top handle and locking casters allow one unit to support commissioning, maintenance shutdowns or short-term production changes in several rooms. The discharge spigot accepts flexible ducting so dry air can be directed into a localized enclosure while the machine remains in a service corridor.

Key Features

Large locking casters and a rigid top handle support controlled movement across smooth factory floors.

A circular discharge collar directs conditioned air through temporary flexible ducting to the affected zone.

The removable inlet filter protects refrigeration surfaces and can be serviced from outside the cabinet.

Automatic restart, hot-gas defrost and a continuous drain connection reduce supervision during extended drying work.

Customer Product Concerns

Temporary moisture events require fast action, but permanent ductwork and fixed dehumidification capacity may not be available at the affected location.

A short production campaign creates a local latent load that does not justify permanent HVAC modification.The wheeled package adds independent moisture removal only for the required period and can then be reassigned.

Placing service equipment inside a clean space consumes floor area and complicates access.A ductable outlet lets the cabinet remain outside the critical zone while dry air is delivered through a temporary connection.

Operators lose drying time when a small condensate tank repeatedly reaches its shutoff level.The hose drain or optional lifting pump transfers water continuously to a nearby floor drain.

A portable machine moves or vibrates when its fan and compressor start.Locking casters, resilient compressor mounts and a low-center-of-gravity steel chassis keep the operating position stable.

Typical Applications

Cleanroom commissioning and moisture pull-downTemporary control during AHU maintenanceSmall airlocks and material transfer roomsLocal drying around sensitive production toolsEmergency response to condensate or water ingress
