WEATHER-RITE™ XT Features & Benefits

  1. Improved indoor air quality - Helps dilute airborne contaminants making exhaust systems operate more efficiently
  2. Augment existing ventilation system - Unit can be designed to automatically modulate outdoor air volume for 20% to 100% to help meet ventilation requirements in cold weather and decrease heat build up in warm weather
  3. More consistent temperatures and less stratification - Optional cooling effectively reduces indoor air temperatures to help keep people and processes productive
  4. Cost savings - Heating systems deliver 100% of the heat generated into the building resulting in energy savings
  5. Flexibility and convenience - Heating systems require little to no ductwork and can be installed indoors or outdoors
  6. Evaporative and mechanical cooling packages available

Optional Cooling Packages:
Evaporative Cooling:

WEATHER-RITE™ XT-Series evaporative cooling system is an economical solution. It requires no air-cooled condenser, no chiller or cooling tower, no chilled water pumps or distribution piping/insulation, no major motor control center or electrical gear. Operating costs are a fraction of similar-capacity mechanical refrigeration systems.

Evaporative cooling works when warm air passes over specially treated wetted media. The heat passes from the air to the wetted media, causing the water to evaporate and inside air to cool.

Mechanial Cooling

For situations requiring temperature and humidity levels lower than the performance parameters available with outdoor air alone or with evaporative cooling, WEATHER-RITE™ XT-Series offer a broad range of cooling options.

Cooling options can be added by simply installing one of our coil sections equipped with the appropriate cooling coils and a condensing unit or chiller. The versatility afforded by the coil section enables you to utilize DX refrigerant, chilled water or other types of cooling coils in your system.

Model Configurations
Make-up Air (MUA) Models
Design: 100% replacement air with a fixed discharge air volume.
Function: Supplies direct replacement air for building mechanical exhaust.
Application: Used as make-up air for industrial processes which incorporate mechanical exhaust.


Air Management (AM) Models
Design: Variable outdoor air from 20% to 100% and modulating burner with a 30:1 turn-down ratio. Discharge air volume is fixed.
Function: Automatically responds to building pressure and temperature needs.
Application: Used in industrial and commercial buildings that have air quality and specific air management requirements.


Fixed Recirculation (FR) Models
Design: Fixed 80% air turnover rate and 20% outdoor air replacement rate. Discharge air volume is fixed.
Function: Provides efficient, low-cost heating where minimum ventilation rates are required.
Application: Used in warehouses, distribution centers, retail outlets, etc.
