Seasons 4 - Commercial Heating and Cooling System Manufacturers

The Seasons•4 Make-Up Air System is another sound approach to humidity control. This system uses multiple compressors staged to provide the dehumidification requirements. The system concept is to reduce the moisture introduced in the outdoor air to the lowest possible level. Because the outdoor conditions vary greatly throughout the day, the multiple compressors used are better able to meet this load variance efficiently. Outdoor air accounts for 100% of the load requirements.

This type of system is very effective in supermarkets that use multi-deck open frozen food display cases. Case credits for this type of case are higher than other types and will provide most of the space sensible load. Units are furnished with return air cooling coils in order to make up any load requirements that the outside air coils do not.

Make-Up Air units include the following features:

• Multiple compressors for efficient load matching and low electric demand
• Independent high efficiency outdoor air pre-cool circuit eliminates "sensible load" cooling burden from dehumidification coils
• Minimum two-stage outdoor air dehumidification circuit for dedicated moisture removal
• Independent return air circuit parallel to outdoor air circuit treats sensible load requirements of space, giving your system built-in flexibility
• Motorized outdoor air with cost-efficient night-bypass damper
• Heat reclaim coils use waste heat derived from your refrigeration system to offset requirements for comfort zone heating
• Auxiliary heat section is specifically designed for your location’s requirements
• Low velocity pleated, long-lasting air filters
• Backward inclined airfoil blade blowers for high-efficiency operation
• Premium efficiency 4-pole motors (exceeds EPAC requirements)
• Single point power connection for easy installation
• Spacious cabinet design with full height access doors, with single handle, multiple point latches, for easy access and maintenance
• Oversized condenser coils designed for higher efficiency and energy savings
• Factory mounted 24-volt controls are compatible to the computer hardware of your choice. Your control system matches your specifications exactly.
