Important Notice

Quest sets a minimum advertised price, so what you see here is the lowest any authorized dealer can publicly list. If another site shows a Quest unit for less, they are not authorized, even if they say they are, and that puts your warranty at risk. Quest can refuse service and support on an unauthorized purchase.

The good news: as an authorized Quest dealer, we'll beat any legitimate price, we just can't post it publicly. Call, text, or email and we'll get you the best price available, plus same-day commercial and bulk quotes.

QUEST'S PATENTED TECHNOLOGY | M-CoRR™

The Hi-E Dry 140 achieves exceptional efficiency through Quest’s proprietary M-CoRR™ (Multi-Coil Refrigerant Recovery) system. Its unique multi-coil design recovers energy within the refrigeration process, allowing the unit to remove more moisture per kilowatt hour while reducing the electrical demand and heat added to the surrounding space.

Designed for demanding commercial environments, M-CoRR™ delivers efficient, dependable drying while supporting a compact and mobile platform. The system helps the Hi-E Dry 140 achieve 7.2 pints/kWh at 80°F/60% RH, providing strong moisture removal, lower operating costs, and reliable performance wherever portable humidity control is required.

How Does M-CoRR™ Work in the Hi-E Dry 140?

M-CoRR™ uses a multi-coil refrigeration process to cool incoming air below its dew point, remove moisture, and recover energy before the dry air returns to the room. Reusing this energy improves water removal per kilowatt hour, reduces unnecessary heat output, and supports efficient operation across changing temperature and humidity conditions in demanding commercial environments.
