Research Products 865 Ductless Humidification System 34.6 Gpd

Product Description

The RESEARCH PRODUCTS 865 is a ductless whole-home humidification system designed for residential and light-commercial applications where forced-air ductwork is not available or practical. Operating at 240 volts and drawing up to 16 amps, this self-contained unit delivers up to 34.6 gallons per day of moisture output to maintain healthy indoor humidity levels. The cabinet measures 10.07 inches long by 7.06 inches wide by 20.87 inches tall, making it a compact unit for its output capacity. Licensed HVAC technicians and mechanical contractors typically handle installation and commissioning.

This unit is suited for spaces that lack a central air handler or ducted return system, such as additions, converted spaces, server rooms, or standalone zones requiring independent humidity control. At 34.6 gallons per day capacity, it is sized for larger residential applications or small commercial spaces. The ductless design allows placement without modifying existing ductwork, simplifying the installation scope in retrofit projects.

Key Features

• 34.6 gallons per day moisture output for high-capacity humidification without a duct connection
• 240-volt, 16-amp electrical supply keeps unit self-contained and independent of low-voltage HVAC controls
• Compact footprint at 10.07 inches x 7.06 inches x 20.87 inches fits in tight mechanical spaces
• Ductless configuration eliminates the need to tie into an air handler or duct system
• Suitable for residential and light-commercial environments requiring standalone humidity management

Compatibility

Designed as a standalone ductless humidification unit for residential and light-commercial spaces that do not have a central forced-air system or require an independent humidification zone.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified electrician familiar with 240-volt branch circuit requirements per NEC guidelines. Shut off power at the breaker panel before making any electrical connections. A dedicated 240-volt circuit sized appropriately for the 16-amp draw is required. Follow all local mechanical and electrical codes, and consult the manufacturer installation manual for drain line routing and water supply connection requirements.
