DewAir™ products supplied by:

Compared to other brands, RH-Cube™ has:

• Raw capacity — our 2.0 ton system can remove more moisture than a 10 ton air conditioner

• More capacity than our CZ model for non-corrosive applications of high humidity & temp.

• Minimal ducting for simpler installation

• Less constrained electrical supply requirements

• Very low energy usage, very low cost of operation

Optimized to pull more moisture where needed For applications such as greenhouses and industrial processing plants where temperatures and humidity levels are high, the RH-Cube 18 HH model is the ideal choice. In some cases, there can be a deployment of both the HH and CZ models to span a wider range of humidity and temperature where the CZ is only used at lower RH and temperatures by means of automation.

The HH model may have it’s condenser outdoors to reduce heat such as industrial processing plants applications, or indoors to recover heat such as greenhouses for 25,000 BTUs of reheat.

RH-Cube 18 HH application selection

Compact | Capacity | Cost effective

High humidity dehumidifier for select applications

The higher capacity of the HH model needs to be

aligned to applications where the range of indoor

air temperature and range of humidity is within the

recommended region for the HH model. Not ob-

serving this will cause cycling that will reduce effi-

ciency. Please refer to the capacity tables on our

website for guidance or request technical support.
