Tranquility® Dedicated Outdoor Air Systems (TOH/R) Horizontal

Overview

ClimateMaster Dedicated Outdoor Air Systems (TOH/R) Series provides the most complete solution for your water-source application. Our many options & configurations allow the design for outdoor air requirements to be incorporated into the water loop system, further enhancing the advantages of a WSHP application. The ability to precisely control leaving air dew point temperature in summer, handle extremely cold entering air temperatures in winter, & perform at part load conditions give designers unmatched flexibility in building design, Indoor Air Quality (IAQ) & energy efficiency.

Precise Leaving Air Temperature Control

• Air temperature leaving dehumidifier controlled to ±0.2°F (±0.1°C)
• Substantial energy savings
• Conditioned outdoor air can be introduced directly into space

Evaporator Coil

• Raised lance fins, rifled tubes maximize moisture removal
• Very high MRE’s (Moisture Removal Efficiency)

Drain Pan

• Stainless steel pan minimizes corrosion

Refrigerant Reheat Coil

• Sized for neutral LAT (65 – 80°F, 18 – 27°C)
• Air separation avoids condensate re-vaporization

Scroll Compressor

• State-of-the-art compressor technology for highest efficiency & reliability
• Quiet operation for less noise
• Over 5 tons (18 kW), multiple compressors are staged to match the load

Fans

• Forward curved centrifugal blowers
• Backward-inclined centrifugal fans, plug fans on larger units

Electrical Service

• Single point power connection, for all units

Controls

• Simple ladder logic addresses wide variety of conditions
• System can handle dehumidification, cooling, & heating
• Occupancy contact ensures outdoor air enters only when needed
