ESC-SERIES EVAPORATIVE COOLING

 

The ESC-Series evaporative cooling unit is a semi-custom fabricated air handler that can utilize direct (DEC) or indirect (IEC) evaporative cooling and a combination of both indirect/direct (IDEC) evaporative cooling to meet specific usage and dimensional requirements. The ESC-Series unit come with various options including service access location, utility connections, airflow arrangements and accessories. The evaporative air handler uses 100% outside air to provide tempered makeup air and whole building cooling. The ESC-Series unit is designed for large industrial or commercial buildings looking to provide better indoor air quality without the equipment or operating costs associated with mechanical cooling. 


PERFORMANCE FEATURES

INDIRECT

  • Designed for large industrial or commercial buildings looking to temper the air in the building without the equipment or operating costs of mechanical cooling 
  • Uses 30 – 40% of the energy of mechanical cooling and maintain temperatures below 85°F on a design summer day when sized properly 


INDIRECT / DIRECT

  • Will provide supply air at 66/63°F at summer design of 105/71°F or 71 tons with 39.6 EER with no mechanical cooling 
  • Options include 304 stainless steel casing, intake louver and screen, 2” permanent intake filters, shut off damper and factory mounted controls
