Leizig Duct Kit (R32 Dehumidifier for LG70, LG100, LG150)

What This Kit Does

The Leizig Duct Kit is a factory-designed accessory that adds dedicated intake and exhaust duct connections to the LG70, LG100, and LG150 dehumidifiers. Without ducting, these units draw return air from and discharge treated air into the same immediate space — functional for open-floor layouts, but a limitation when your design calls for the unit to sit outside the conditioned room, in a mechanical chase, or overhead in a plenum.

With this kit installed, the dehumidifier can be positioned remotely and connected to the grow environment via duct runs for both inlet and outlet air paths. This separates the mechanical footprint from the canopy footprint, reduces in-room noise, simplifies filter access, and frees up valuable square footage on the grow floor. It is the correct OEM solution for any Leizig LG70, LG100, or LG150 installation where the unit will not be sitting open on the room floor.

Who It's For

This kit is relevant for commercial cannabis and hemp cultivation facilities where the dehumidifier is part of a larger HVAC design rather than a standalone floor unit. That includes sealed flower rooms with overhead mechanical space, multi-room builds where a single Leizig unit serves a zone via ducted distribution, and facilities running an air handling unit (AHU) alongside the dehumidifier — a configuration the Leizig line is specifically designed to support.

It also suits operators who are retrofitting an existing room and need to move the dehumidifier out of the canopy zone to reclaim floor or aisle space. If you are running vertical racks or high-density benching, eliminating a floor-mounted dehumidifier from the room equation is often worth the install complexity — this kit makes that possible with the LG70, LG100, and LG150.

Leizig LG-Series Dehumidifier Platform

The Leizig commercial dehumidifier line is built specifically for high-humidity cultivation environments. Units feature galvanized steel construction with corrosion-resistant surface treatments — relevant in grow rooms where chemical exposure from nutrients, foliar sprays, and CO2 injection accelerates wear on standard equipment. Leizig units are engineered for low acoustic output, which matters in facilities where noise levels affect staff and where vibration can disturb sensitive HVAC instrumentation.

The LG70, LG100, and LG150 models operate on R32 refrigerant — a lower global warming potential (GWP) refrigerant relative to legacy R410A, with high heat transfer efficiency. The broader Leizig line supports MODBUS integration for environmental controller connectivity, and the units are rated for paired operation with AHU systems for managing humidity in low-temperature, high-moisture growing conditions. High-efficiency filtration is standard across the line to protect both the unit's coil and the crop from airborne microbes.

Ordering and Compatibility — Confirm Before You Buy

This duct kit is model-specific. It is engineered and dimensioned for the Leizig LG70, LG100, and LG150 only. It is not interchangeable with other Leizig models in the line (LG228, LG508, LG880, etc.) or with duct kits from other dehumidifier brands. Before ordering, confirm your unit's model designation on the nameplate.

If you are speccing a new Leizig dehumidifier and already know your installation requires ducting, order this kit alongside the unit — lead times and shipping on accessories should align with the main unit so the installation is not delayed waiting on a secondary shipment. Contact HSC to coordinate both the dehumidifier and this kit as part of a single project order.
