Leizig Thermal Management Co., Ltd. (NASDAQ: LZIG) is a global leader in industrial thermal management — ventilation, refrigeration, dehumidification, and heat exchange. Originally founded in Sydney, Australia in 1990 as Rack Technologies, Leizig expanded into manufacturing in Guangzhou, China in 2003, building a portfolio of 50+ patents (10 invention, 20 utility model, 20 appearance). Their dedicated Leizig Climate division brings that industrial-grade engineering to commercial cannabis cultivation with purpose-built dehumidifiers and circulation fans.
Leizig has transitioned to an all-VFD (Variable Frequency Drive) lineup. VFD units use variable speed components to reduce cycling, maintain a more consistent humidity set point, and deliver a significantly greater lifespan compared to standard compressor units. Every dehumidifier features R410A refrigerant, galvanized steel construction with corrosion-resistant coatings, MERV-8/13 filtration, and RS485 (Modbus) communication for integration with commercial environmental controllers. Four installation methods — ceiling-suspended, wall-mounted, floor cabinet, or freestanding — and all units operate below 73 dB(A).
All models now feature Variable Frequency Drive technology — variable speed components reduce cycling, maintain consistent set points, and extend unit lifespan.
The flagship LG880-VFD delivers 880 pints/day with Variable Frequency Drive technology — purpose-built for warehouse-scale cultivation and multi-room commercial operations. Ceiling-mount design with dual blower fans maximizes floor space.
Directional forced-air circulation fans designed to promote consistent plant movement for even light distribution and eliminate microclimates across the canopy. Double ball bearing system for durability, cantilevered mounting brackets for quick install and relocation, and snap-in grilles for easy cleaning.
Available in 120V, 240V, and 277V configurations
Every dehumidifier includes RS485 communication protocol and remote dry contact input for seamless integration with commercial environmental controllers like TrolMaster, Argus, and Priva.
Rated air filtration protects plants from harmful microbes while maintaining optimal airflow. Standard MERV-8 with MERV-13 upgrade available for facilities requiring tighter particulate control.
Ceiling-suspended (hoisted), wall-mounted, floor cabinet, or freestanding. Every unit adapts to your facility layout without custom fabrication or additional hardware.
Corrosion-resistant surface coatings over galvanized steel for maximum durability in high-humidity grow environments. Built to last through years of continuous 24/7 operation.
All models operate below 73 dB(A) — industry-leading minimal noise for occupied grow environments. The LG228 achieves just 68 dB(A), the quietest in the commercial dehumidifier category.
All dehumidifiers use R410A refrigerant for efficient moisture removal across a 56–95°F operating range. Continuous condensate removal via 3/4″ NPT threaded drain connection.
