ALL IN ONE Heat Exchanger: Advanced IEC Technology

The ALL IN ONE Heat Exchanger (HX) is the next-generation Plate type, Crossflow, Air-to-Air heat exchanger engineered for superior Indirect Evaporative Cooling (IEC) performance. The IEC operations refer to the two separate airflow streams within the exchanger that enable cooling without adding moisture to the supply air. This technology is designed to deliver high cooling efficiency, significant energy savings, and long-term operational reliability for both industrial and commercial applications.

How the Indirect Evaporative Cooling Works

  • Primary (Dry) Air Stream: Warm supply air passes through the dry channels of the HX, separated by thin engineer polymer plates.
  • Secondary (Moist) Air Stream: Exhaust air flows through the wet channels where a thin film of water is present.
  • Heat Exchange Process:
    • Heat from the dry channel passes through the plate into the wet channel.
    • The heat evaporates the thin water film on the wet side.
    • The primary air is cooled sensibly (temperature reduction without moisture addition).
    • The secondary air absorbs the moisture and is exhausted.
  • This crossflow arrangement ensures zero moisture carryover to the supply air and enables consistent, reliable cooling performance.

Performance & Energy Savings

  • ALL IN ONE HX-based IDEC systems can replace conventional air-conditioning in some comfort cooling as well as ventilation applications, using up to 30% less energy.
  • Indirect-Direct Evaporative Cooling (IDEC) systems can completely eliminate conventional HVAC systems in certain climates.
  • Pre-cooling with ALL IN ONE HXs reduces load on DX or chilled water cooling coils in Hybrid AHUs and Treated Fresh Air (TFA) units.

Key Types of Air-to-Air Heat Exchangers

Plate Heat Exchangers

Use parallel plates (often aluminum) to maximize surface area. Ideal for high-efficiency, space-constrained, or commercial applications.

Rotary Heat Exchangers (Heat Wheels)

A rotating matrix absorbs heat from one stream and releases it into another, offering high efficiency in a compact design.

Tubular / Heat Pipe Exchangers

Use tubes or passive phase-change fluid to transfer heat. Suitable for high-temperature or dusty environments.

Run-Around Systems

Circulating fluid transfers heat between separate air streams. Useful for long-distance heat transfer.
