Regenerative Heat Recovery Technology

DOHAIS System

Discover
DOHAIS System represents a breakthrough in HVAC technology, prioritizing medical-grade hygiene, superior energy efficiency, and climate responsibility.

Below is a detailed breakdown of the features and benefits of this Regenerative Heat Recovery technology:

Core Technology: Regenerative Heat Recovery

The standout feature of this system is its ability to operate without a traditional outdoor unit, significantly reducing the carbon footprint.

  • Outdoor-Less Design: It utilizes a Regenerative Heat Pipe that leverages hot water and hot gas directly from the compressor.

  • Energy Recycling: Instead of wasting heat, the system recovers and repurposes it to maintain thermodynamic balance, making it exceptionally energy-efficient.

Advanced Air Purification (DOHAIS)

Designed to create a "Clean and Comfortable" environment that prevents the spread of infections:

  • Plasma Technology: Filters and neutralizes bacteria, dust, and smoke particles as small as 0.01 microns.

  • Oxygen Enrichment: Ensures high air quality by maintaining sufficient oxygen levels through plasma-treated air.

  • Odour Neutralization: Effectively eliminates unpleasant smells, including persistent cigarette smoke.

High-End Material & Construction

Built for durability and hygiene, specifically for environments like hospitals, labs, and premium commercial spaces:

  • Stainless Steel Build: The AHU (Air Handling Unit) is constructed from high-grade stainless steel to prevent rust and contamination.

  • Protective Coatings: Cooling coils are treated with anti-corrosion and anti-fungal layers to stop biofilm and mold growth.

  • RockWool Insulation: Provides superior thermal insulation and fire resistance, preventing condensation and energy loss.
