Dehumidification Solutions: The Ultimate Starter’s Guide

Conquer moisture, enhance air quality, and protect your assets with the right portable dehumidification unit for your space.

Do you struggle with stagnant moisture and mold growth in your warehouse, jeopardizing your products and employees? Are you looking for a unit to remove the moisture from a water-damaged building after a flood? Have you come to expect unreliable, poorly-manufactured moisture removal equipment to break down every year? 

Chances are you’re in the market for a commercial portable dehumidifier, and TEMP-AIR® Equipment Sales is your trusted partner for all needs related to portable HVAC equipment. This starter’s guide answers the top questions asked by real people who have considered buying or already purchased a unit.

What is a portable commercial dehumidifier?

A commercial dehumidifier is the best unit to reduce indoor humidity, improve air quality, to restore water-damaged areas, and to facilitate process drying. While many are designed to tackle significant moisture loads in large spaces, many of these units also double as heaters, air conditioners, or air purification systems. When selecting a portable commercial dehumidifier, it’s essential to know there are two different operating systems: low-grain refrigerant (LGR) and desiccant.

LGR dehumidifiers utilize refrigerant coils to cool the air and condense moisture, removing humidity from the air efficiently and thoroughly, even in challenging environments. LGR dehumidifiers suitable for water damage restoration, construction sites, and large-scale manufacturing processes where controlling moisture is critical, and the LGR technology allows these units to operate effectively across a range of temperatures and humidity levels.

On the other hand, desiccant dehumidifiers work by passing air over a silica gel-coated wheel to absorb moisture. The silica gel naturally absorbs moisture from the air without relying on cooling or refrigerant, making these units highly effective in cold climates or in processes requiring very dry conditions. Desiccant dehumidifiers can provide quality control in pharmaceuticals, food processing, and electronics manufacturing, where precise humidity control is essential for quality and safety.

Both types of units are designed for mobility, durability, and high performance. Overall, dehumidifiers help prevent the growth of mold and mildew, protect sensitive equipment from corrosion, and maintain the integrity of building structures, potentially saving industrial operators time and money on maintenance and repair costs. Whether it’s simply humidity removal or a strict process drying event, there is, in fact, a unit out there to meet your exact needs.
