Overview

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 it works ?

Primary (Dry) Air Stream: Warm supply air passes through the dry channels of 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 HX s reduces load on DX or chilled water cooling coils in Hybrid AHUs and Treated Fresh Air (TFA) units.
Energy Savings Examples
- IEC assisted TFA: Up to 30% less energy compared to conventional TFAs.
- IEC assisted Hybrid AHU: Up to 30% less energy while delivering three times more fresh air to conditioned spaces.
